A prática regular de exercício físico traz inúmeros benefícios para os idosos, mas é necessário identificar uma prescrição de treinamento que possa ser realizada de maneira segura e eficaz por esta população. O Treinamento Multimodal é uma alternativa para estimular as capacidades e habilidades físicas importantes para a manutenção da saúde e autonomia no envelhecimento. O objetivo deste estudo, de abordagem quantitativa e delineamento quase-experimental, foi medir a confiabilidade de um circuito multimodal incremental na determinação do limiar anaeróbio (LAN) de idosos por meio da dosagem do lactato sanguíneo. O estudo foi aprovado por Comitê de Ética em Pesquisa. Foram identificadas variáveis sociodemográficas e clínicas. As variáveis clínicas foram medidas antes, durante e após sessões de treinamento em um circuito multimodal. Para as análises descritivas, foram calculadas as frequências absolutas, porcentagens, medianas, médias e desvio padrão. Para a análise de confiabilidade intraobservador e de concordância, foram utilizados o Coeficiente de Correlação Intraclasse (CCI) e o teste de concordância Bland-Altman, usando o pacote estatístico SPSS® V24. Para a identificação da igualdade de médias no teste e no reteste foram utilizados os testes paramétricos t-pareado e One-way ANOVA medidas repetidas, para variáveis contínuas e com distribuição normal, tomadas nos momentos antes e depois. Para os casos onde as suposições de normalidade e/ou esfericidade não foram atendidas, foram utilizados os testes não paramétricos de Wilcoxon ou Friedman. A intensidade do limiar anaeróbio (ILAN) e a Frequência Cardíaca na Intensidade do Limiar Anaeróbio (FCILAN) foram identificadas a partir de três critérios. Participaram do estudo 20 idosos, na maioria mulheres, com idade entre 60 e 65 anos, de cor branca, convivendo com companheiro, com mais de 12 anos de escolaridade, aposentados. Ao testar a reprodutibilidade da ILAN em dois momentos distintos com o mesmo avaliador, observamos que a média dos escores obtidos no teste e reteste foi semelhante (>,05) indicando boa correlação entre os pares analisados (r = ,77 a ,91). Nossos resultados também mostraram alta confiabilidade em todos os critérios adotados para determinação do LAN (CCI=,86 a ,95), além de boa concordância das medidas teste e reteste para o LAN2 do 1° e 3° critérios por meio do método de análise Bland-Altman. Identificamos redução da pressão arterial na primeira hora após o treinamento em circuito, em comparação com os valores pré-intervenção, nos momentos teste e reteste. O principal achado de nosso estudo se deu pela confiabilidade e concordância entre as medidas teste-reteste para as variáveis estudadas, sugerindo adequação do circuito multimodal incremental na determinação do LA de idosos por meio da dosagem do Lactato Sanguíneo / Regular physical activity brings several benefits to elderly people, but it\'s necessary to identify a training prescription that can be performed in a safe and effective manner for this population. The Multimodal Training is an alternative to stimulate physical skills and abilities important to maintaining health and autonomy in aging. The purpose of this study, with quantitative approach and quasi-experimental delineation, was to measure the reliability of an incremental multimodal circuit in the determination of the anaerobic threshold (ANT) of elderly people through blood lactate dosage. The study was approved by the Ethics in Research Committee. Social demographic clinical variables were found. Clinical variables were measured before, during and after the training sessions in a multi-modal circuit. For descriptive analysis, absolute frequencies, percentages, medians, averages and standard deviation were calculated. For intra-observer reliability and agreement analysis, we used the Interclass Correlation Coefficient (ICC) and Bland-Altman agreement test, using statistical package, SPSS® V24. To the measures equality identification in the test and retest were used the t-paired parametrics and One-way ANOVA repeated measures, to continuous variables and with normal distribution, taken moments before and after. To the cases where normality and/or spherecity were not satisfied, we used Wilcoxon or Friedman non-parametric tests. The anaerobic threshold intensity (ATI) and the heart rate in the anaerobic threshold intensity (HRATI) were identified according to three criteria. Participated in the study 20 elderly people, mostly women, between the ages of 60 and 65 years old, white colored, living with a partner, with more than 12 years of schooling, retired. When testing the reproducibility of ATI in two different times with the same evaluator, we observed the measure of the obtained scores in the test and retest was similar to (>,05), indicating a good correlation between the analyzed pairs (r = ,77 a ,91). Our results also showed high reliability in all adopted criteria to determine ATI (CCI=,86 a ,95), in addition to the good agreement of the test and retest measures to the ATI2 of the first and third criteria through Bland-Altman analysis method. Was identified arterial pressure reduction in the first hour after the circuit training, compared with preintervention values, in the test and retest moments. The main discovery was given through reliability and agreement between measures test-retest to the studied variables, suggesting adjustment of the incremental multimodal circuit in the determination of the elderly people ATI through blood lactate dosage

Hipotensão pós-exercício é o fenômeno de redução da pressão arterial sistêmica por minutos ou horas após a realização de atividade física, sendo considerado uma resposta fisiológica para o controle pressórico. Fatores como nível pressórico, aptidão física e tipo de exercício físico, contribuem para potencializar a resposta hipotensora pós-exercício, contudo, apesar de ser conhecido que a pressão arterial não possui valor constante ao longo das 24 horas, ainda não foi investigado se existe diferença na resposta hipotensora quando o exercício físico é realizado em diferentes horários do dia. À vista disso, 16 mulheres foram divididas em dois grupos; Adultos Maduros (n=8; 58,7 + 10,9 anos) e Adultos Jovens (n=8; 21 + 4,3 anos). Cada grupo realizou três sessões experimentais; duas compostas de exercício físico resistido de baixa intensidade (dez exercícios a 40% de uma repetição máxima) realizados em diferentes fases do dia, manhã (07:30h) e noite (18:00h), e uma sessão controle - sem a realização de exercício físico. A pressão arterial foi medida por 24 horas após as sessões, a percepção de desconforto avaliada por meio de inventário. Em suma, descrevemos que: (1) Não constatamos redução pressórica no grupo Adultos Jovens em nenhuma das fases avaliadas. Observamos hipotensão pós-exercício no grupo Adultos Maduros de forma intermitente por 5 horas na variável pressão arterial média após o exercício realizado na fase matutina. Com base na análise de Fourier e da própria observação do comportamento pressórico da pressão arterial média, podemos observar que o exercício matutino atenuou o padrão pressórico ultradiano, como consequência, a pressão arterial média manteve-se a níveis abaixo da sessão controle; (2) Na avaliação da percepção de desconforto, o grupo Adultos Jovens quando comparado com o grupo Adultos Maduros, apresentou maior desconforto ao realizar o exercício na fase matutina, já na sessão com exercício noturno, encontramos pouca alteração na percepção de desconforto de adultos jovens e adultos maduros / Post exercise hypotension is a phenomenon of decreased blood pressure by minutes or hours after physical exercise, being considered a physiological response in blood pressure control. Factors such as blood pressure level, physical ability and type of exercise, contribute to potentiate post exercise hypotension, however, despite being known that blood pressure has no constant value over 24 hours, still not been investigated whether there are differences in the hypotensive response when exercise is performed at different times of the day. In view of this, 16 women were divided into two groups; Mature adults (n = 8; 58.7 ± 10.9 years) and Young Adults (n = 8; 21 ± 4.3 years). Each group performed three experimental sessions; two with low intensity resitance exercise (tem exercise at 40% one repetition maximum) was performed at two phases, morning (07: 30h) and night (18: 00h), and a control session without performing physical exercise. Blood pressure was measured during 24 hours after the sessions, perception of discomfort assessed by inventory. We describe that: We did not found blood pressure reduction in Young Adults group for none of the phases. We observed intermittently post-exercise hypotension Mature Adults group for five hours in mean arterial pressure after morning exercise. Based on Fourier Analysis and own observation mean arterial pressure behavior, we can observe that the morning exercise attenuated ultradian pressor pattern, As a result, average blood pressure levels remained below than control session; (2) In assessing the perception of discomfort, Young Adults group compared with Mature Adults group, showed greater discomfort to perform the exercise in the morning phase, during nightly exercise, we found little perception of discomfort change in Young Adults and Mature adults

Uma sessão de exercícios resistidos promove hipotensão pós-exercício em hipertensos (HT). Devido às alterações cardiovasculares impostas pela doença, é possível que os HT apresentem mecanismos hipotensores diferentes dos observados em normotensos (NT). Além disso, os HT utilizam medicamentos anti-hipertensivos que podem afetar as respostas fisiológicas pós-exercício. O objetivo desta tese foi avaliar, em homens HT, o efeito de uma sessão de exercício resistido sobre a pressão arterial (PA) e seus os mecanismos hemodinâmicos e autonômicos, comparando este efeito com o observado em NT e verificando o efeito do uso do captopril sobre estas respostas. Participaram do estudo, 12 HT (50±3anos) e 14 NT (44±3anos). Os hipertensos foram estudados em duas situações: após 4 semanas de placebo ou captopril (3 x 50mg/dia) administrados em formato crossover e de forma duplo-cega. Os NT foram estudados apenas 1 vez sem nenhum medicamento. Em cada grupo/situação experimental os voluntários realizaram 2 sessões experimentais conduzidas em ordem aleatória: Controle (repouso) e Exercício (6 exercícios, 3 séries até a fadiga moderada, 50% de 1RM). As variáveis foram medidas antes e em 2 momentos pós-intervenções: Pós1 (entre 30-80min) e Pós2 (após 7h). Além disso, a PA foi medida por 24h em condições ambulatoriais. No Pós1, a PA sistólica diminuiu de forma similar nos grupos/situações (NT=-8±2; HT não medicado=-13±2; HT medicado=-12±2mmHg). A PA diastólica também diminuiu, mas a queda foi maior nos HT não medicados em comparação com os NT (-9±1 vs. -4±1mmHg, respectivamente) e foi igual nos hipertensos com e sem medicamento. Em cada grupo/situação, a hipotensão pós-exercício se acompanhou de redução do débito cardíaco (DC) em parte dos voluntários e da resistência vascular periférica (RVP) na outra parte. O volume sistólico (VS) diminuiu (NT=-14±5; HT não medicado=-11±5; HT medicado=-17±5ml) e a FC aumentou (NT=+13±3; HT não medicados=+13±2; HT medicados=+13±2bpm) pós-exercício de forma similar nos grupos/situações. Também de forma similar, o balanço simpatovagal cardíaco aumentou (NT=+1,9±0,4; HT não medicados=+1,4±0,3; HT medicados=+1,8±0,3) e a sensibilidade barorreflexa diminuiu (NT=-5±1; HT não medicados=-4±2; HT medicados=+3±1mmHg/bpm) pós-exercício. No Pós2, não houve efeito do exercício sobre nenhuma variável. A PA ambulatorial foi semelhante em todos os grupos/situações. Em conclusão, uma sessão de exercício resistido promove efeito hipotensor no ambiente laboratorial em NT e HT medicados ou não, mas este efeito não se mantém em condições ambulatoriais. Nos HT, a magnitude de queda da PA diastólica é maior que nos NT. Os mecanismos hemodinâmicos e autonômicos da hipotensão pós-exercício são semelhantes em NT e HT medicados ou não. O determinante hemodinâmico (DC ou RVP) da hipotensão pós-exercício varia de um indivíduo para outro, mas a redução da PA se acompanha de redução do VS e aumento da FC, sendo este último resultante do aumento do balanço simpatovagal cardíaco e da redução da SB / A session of resistance exercise promotes post-exercise hypotension in hypertensive subjects (HT). Due to the cardiovascular alterations imposed by the disease, it is possible that HT present hypotensive mechanisms different from those observed in normotensive subjects (NT). Moreover, HT frequently receive antihypertensive medications that might affect post-exercise responses. The aim of this thesis was to evaluate, in HT men, the effects of resistance exercise session on blood pressure (BP) and its hemodynamic and neural mechanisms, comparing these effects with the responses observed in NT and verifying the effect of captopril use on these responses. Twelve HT (50±3 years) and 14 NT (44±3 years) participated in the study. HT were studied in two situations, after 4 weeks of placebo and captopril (3 x 50mg/day) administered in a crossover double-blind design. NT was studied only once without any medication. At each group/situation, subjects underwent 2 experimental sessions performed in a random order: Control (rest) and Exercise (6 resistance exercises, 3 sets until moderated fatigue, 50% of 1RM). Measurements were taken before and in 2 post-intervention moments (Post1 - between 30-80min and Post2 - after 7pm). Moreover, ambulatory BP was measured after the sessions. In Post1, systolic BP decreased similarly in all groups/situations (NT=-8±2; unmedicated HT=-13±2; medicated HT=-12±2mmHg). Diastolic BP also decreased, but this decrease was greater in unmedicated HT compared with NT (-9±1 vs. -4±1mmHg, respectively), and were similar in HT with and without medication. Regardless of group/situation, exercise promoted a decrease in cardiac output (CO) in some subjects and a reduction in systemic vascular resistance (SVR) in others. Stroke volume (SV) decreased (NT=-14±5; unmedicated HT=-11±5; medicated HT=-17±5ml) and HR increased (NT=13±3; unmedicated HT=13±2; medicated HT=13±2bpm) after exercise similarly in all groups/situations. Also similarly between groups/situations, cardiac sympathovagal balance increased (NT=+1,9±0,4, unmedicated HT=+1.4±0.3, medicated HT=+1,8±0,3) and BS decreased (NT=-5±1; unmedicated HT=-4±2; medicated HT=+3±1mmHg/bpm) post-exercise. In Post2, in all groups/situations, exercise did not affect any variable. In addition, ambulatory BP was similar after the control and exercise sessions in all group/situation. In conclusion, a single bout of resistance exercise session promotes post-exercise hypotension in the laboratory in NT and HT subjects receiving or not captopril, but this hypotensive effect is not maintained under ambulatory conditions. The magnitude of BP decrease is greater in non-medicated HT than in NT, and it was not changed by captopril. Autonomic and hemodynamic mechanisms of post-exercise hypotension are similar in NT and HT receiving medication or not. The hemodynamic determinant (CO or SVR) of post-exercise hypotension varies from one subject to another. However, BP reduction is accompanied by decrease in SV and an increase in HR that results from an increase in cardiac sympathovagal balance and decrease in BS

Estudo de abordagem quantitativa e delineamento quase-experimental com o objetivo de comparar os efeitos dos exercícios dinâmicos contínuo e intervalado sobre a magnitude e duração da resposta hipotensora em hipertensos. A amostra foi composta por 20 idosos hipertensos de um município do interior paulista. As variáveis estudadas foram agrupadas nas categorias: sociodemográficas, antropométricas e hemodinâmicas. Cada participante foi submetido duas sessões de exercício físico, com intervalo de uma semana entre os treinos. As sessões de exercício contínuo foram realizadas a intensidade do limiar anaeróbio. Nas sessões de exercício intervalado, os indivíduos trabalharam no limiar de compensação respiratória por 4 minutos durante a fase ativa; na fase de recuperação, trabalharam a 40% do consumo máximo de oxigênio por 2 minutos. O tempo total de cada sessão foi de 42 minutos. Para obtenção dos dados hemodinâmicos, os participantes realizaram três exames de Monitorização Ambulatorial da Pressão Arterial (MAPA), com duração de 24 horas: MAPA controle, MAPA após exercício contínuo e MAPA após exercício intervalado. As análises descritivas, com cálculo de frequências absolutas e porcentagens e descrição das médias, desvio padrão e medianas, foram realizadas por meio do pacote estatístico SPSS, versão 15.0. A descrição das diferenças proporcionais entre os grupos foi realizada primordialmente por meio de aplicação do teste estatístico não paramétrico de Wilcoxon. Em todas as análises, foi adotado o nível de significância estatística de 5% (p<0,05).Quando comparamos os resultados da MAPA realizada após o exercício contínuo aos valores derivados da MAPA controle, encontramos diferença estatisticamente significante para as variáveis Pressão Arterial Sistólica (PAS) vigília (p<0,001), PAS sono (p<0,001), Pressão Arterial Diastólica (PAD) vigília (p<0,001), PAD sono (p<0,001), Pressão Arterial Média (PAM) vigília (p<0,001), PAD sono (p<0,001), Frequência cardíaca (FC) sono (p<0,03) e Duplo Produto (DP) vigília (p<0,002) e sono (p<0,001), sendo que todos os índices mostraram redução após a prática do exercício contínuo. À comparação dos resultados da MAPA após exercício intervalado aos resultados da MAPA controle, constatamos que, após a prática de exercício, houve redução nos valores de PAS vigília (p<0,001), PAS sono (p<0,001), PAD vigília (p<0,001), PAD sono (p<0,001), PAM vigília (p<0,001), PAM sono (p<0,001) e DP vigília (p<0,001) e DP sono (p<0,001). Na comparação do exercício contínuo ao intervalado, encontramos diferença estatisticamente significante para as variáveis PAS vigília (p<0,001) e sono (p<0,01), PAD vigília (p<0,001), PAM vigília (p<0,001), PAM sono (p<0,01), DP vigília (p<0,01) e DP sono (p<0,001), que se mostraram mais reduzidas após a prática do exercício intervalado. Concluímos que a prática de exercício físico contínuo e intervalado promove a hipotensão pós-exercício (HPE) ao longo das 20 horas subsequentes à atividade. O exercício intervalado gera maior magnitude de HPE e menor sobrecarga cardiovascular em comparação ao exercício contínuo. / Quantitative study with a quasi-experimental design to compare the effect of continuous and interval dynamic exercises on the magnitude and length of the hypotensive response in hypertensive patients. The sample consisted of 20 hypertensive elderly patients from a city in the interior of the State of São Paulo, Brazil. The study variables were grouped in the following categories: sociodemographic, anthropometric and hemodynamic. Each participant was submitted to two physical exercise sessions with a one-week interval between the training. The continuous exercise sessions were held at the intensity level of the anaerobic threshold. In the interval exercise sessions, the participants exercised at the respiratory compensation threshold for four minutes during the active phase; in the recovery phase, they worked at 40% of the maximum oxygen consumption for two minutes. The total length of each session was 42 minutes. To obtain the hemodynamic data, the participants undertook three outpatient Ambulatory Blood Pressure Monitoring (ABPM) tests, which took 24 hours: control ABPM, ABPM after continuous exercise and ABPM after interval exercise. For the descriptive analyses, including the calculation of absolute frequencies and percentages and the description of means, standard deviations and medians, the statistical software SPSS version 15.0 was used. The description of the proportional differences between the groups was mainly based on the application of Wilcoxon\'s non-parametric statistical test. In all analyses, statistical significance was set at 5% (p<0,05).When comparing the ABPM results after continuous exercise with the results of the control ABPM, a statistically significant difference was found for the variables Systolic Blood Pressure (SBP) wake (p<0.001), SBP sleep (p<0.001), Diastolic Blood Pressure (DBP) wake (p<0.001), DBP sleep (p<0.001), Mean Blood Pressure (MBP) wake (p<0.001), MBP sleep (p<0.001), Heart frequency (HF) sleep (p<0.03) and Double Product (DP) wake (p<0.002) and sleep (p<0.001). All indices showed a drop after continuous exercise. In the comparison between the ABPM results after interval exercise with the control ABPM results, after the exercise, the following levels dropped: SBP wake (p<0.001), SBP sleep¬ (p<0.001), DBP wake (p<0.001), DBP sleep (p<0.001), MBP wake (p<0.001), MBP sleep (p<0.001) and DP wake (p<0.001) and DP sleep (p<0.001). In the comparison between the continuous and interval exercises, a statistically significant difference was found for the variables SBP wake (p<0.001) and sleep (p<0.01), DBP wake (p<0.001), MBP wake (p<0.001), MBP sleep (p<0.01), DP wake (p<0.01) and DP sleep (p<0.001), which were lower after the interval exercise sessions. In conclusion, the practice of continuous and interval physical exercise promotes post-exercise hypotension (PEH) during the 20 hours after the exercise. Interval exercises lead to a larger HPE and less cardiovascular burden in comparison with continuous exercise.

Este estudo teve como objetivo comparar o efeito agudo de três métodos de recuperação pós-exercício (recuperação ativa, passiva e crioterapia) sobre o desempenho físico, marcadores fisiológicos, psicológicos, bioquímicos e imunológicos, bem como os sentidos atribuídos por sujeitos treinados. Doze corredores treinados em provas de meio-fundo e fundo, voluntários, do gênero masculino (idade: 20,6 ± 1,7 anos; Massa corporal: 64,1 ± 5,6 Kg; Estatura: 1,74 ± 0,05 m.; Gordura corporal: 6,8 ± 2,7 %; VO2máx: 57,0 ± 5,9 mL.Kg-1.min-1; vVO2máx: 15,7 ± 1,7 Km/h; Tlim: 603 ± 243 s.) realizaram três corridas de 30 minutos, em esteira rolante, a 80% da vVO2max, estimado através de teste incremental. Em seguida foram aplicados os métodos de recuperação ativa (corrida a 40% da vVO2max), passiva (sentado em uma cadeira) e crioterapia (imersão em água com gelo quebrado a 5° [±1º] até a altura da crista ilíaca) por 20 minutos, em ordem contrabalanceada. Logo após, os sujeitos realizaram um teste de corrida (Tlim) a 100% da vVO2max. Uma semana antes da realização dos testes, foi realizado um procedimento de familiarização com os métodos de recuperação a serem aplicados. As taxas dos marcadores tempo limite de corrida, distúrbio de humor total, razão fadiga/vigor, percepção subjetiva de esforço, frequência cardíaca, lactato, IL-6, TNF-, leucócitos, neutrófilos, monócitos e linfócitos foram mensuradas no momento anterior a corrida (M1), após a corrida na esteira rolante (M2), imediatamente após a aplicação dos métodos recuperativos (M3) e após a aplicação do teste de corrida tempo limite (M4), exceto a PSE que foi mensurado no M1 e M4, e o Tlim e a entrevista (para análise de representações sociais) que foram realizadas no M4. Foram retirados 18ml de sangue venoso, em cada momento de coleta, para realização dos procedimentos de análise sanguínea. Após os resultados concluímos que o uso dos métodos de recuperação ativa, passiva ou crioterapia durante 20 minutos após uma corrida de 30 minutos a 80%vVO2máx não afetou o desempenho subsequente de corrida a 100%vVO2máx até a exaustão. A crioterapia promove maior queda na frequência cardíaca e menor remoção de lactato após exercício a 80%vVO2máx comparada aos métodos de recuperação ativa e passiva, promovendo maior produção de lactato e menor resposta cronotrópica durante corrida subsequente a 100%vVO2máx até a exaustão e que o uso da crioterapia não interfere na percepção de esforço e nas respostas psicológicas após o esforço, mas induz uma maior perturbação sobre os marcadores imunológicos, especificamente, sobre leucócitos e linfócitos. Na perspectiva qualitativa, verificou-se uma variedade discursiva sobre a escolha do melhor método de recuperação. Os sentidos que mais se destacaram foram: uma maior leveza do corpo, acalmando a musculatura e fica mais... assim, relaxado na crioterapia; ação natural do corpo e quando se está cansado paramos para descansar na recuperação passiva e; continuidade de movimentos, operabilidade, manutenção do ritmo e da normalidade na recuperação ativa / This study aimed at comparing the acute effect of three post-exercise recovering methods (active, passive and cryotherapy recovering) on the physical performance, physiological, psychological, biochemical, immunological, performance and sense markers attributed by trained subjects. Twelve male volunteer runners (aged 20.6 + 1.7 years old; Body mass: 64.1 + 5.6 kg; Height: 1.74 + 0.05 m; Body fat 6.8 + 2.7%; VO2máx: 57,0 ± 5,9 mL.Kg-1.min-1; vVO2máx: 15,7 ± 1,7 Km/h; Tlim: 603 ± 243 s.) trained in middle-distance and distance races have accomplished three 30-minute runnings on a treadmill at 80% of the vVO2, estimated through an incremental test. After that, the active (running at 40 % of the vVO2max), passive (sitting on a chair) and cryotherapy (immersion in water with broken ice at 5° [+ 1°] until the height of the iliac crest) recovering methods were applied for 20 minutes in counterbalanced order. Then, the subjects carried out a running test (Tlim) at 100% of the vVO2max. One week before the accomplishment of the tests, a procedure in order to familiarize them with the recovering methods to be applied was carried out. The running limit time markers, total humor disturb, fatigue/vigor ratio, subjective perception of effort, heart rate, lactate, IL-6, tnf-, leucocytes, neutrophils and lymphocytes rates were measured at the moment before the running (M1), after running on the treadmill (M2), immediately after applying the recovering methods (M3) and after doing the limit time running test (M4), except the PSE, which was measured in M1 and M4, and the Tlim and the interview (to analyze the social representations), which were carried out in M4. 18 ml of venous blood were taken, in each moment of the blood collecting so as to carry out the blood analysis procedures. After the results, we reached the conclusion that the use of active, passive and cryotherapy recovering methods within 20 minutes after a 30-minute running at 80%vVO2máx hasnt affect the performance of a following running at 100%vVO2máx until exhaustion. The cryotherapy promotes a higher fall in the heart rate and a smaller lactate removal after the exercise at 80%vVO2máx, compared to the active and passive recovering methods, thus promoting higher production of lactate and a smaller chronotropic response during the follow-up running at 100%vVO2máx until exhaustion; and that the use of cryotherapy does not interfere in the effort perception or in the psychological responses after effort, but it leads to a higher disorder on the immunologic markers, specifically on the leucocytes and lymphocytes. Within the qualitative perspective, it was verified a discursive variety about the choice of the best recovering method. The senses which were highlighted most were, a larger lightness of the body, calming the muscles down and it gets sort of, relaxed in cryotherapy; natural action of the body and when youre tired we stop to rest in the passive recovering; and, continuity of movement, operability, keeping the rhythm and the normality in the active recovering

This paper investigates the importance of electrical stimulation (E-Stim) treatment pre- exercise, during exercise, and post-exercise on knee pain management and exercise performance on individuals with knee injuries. Common problems from which individuals experience pain and injuries are arthritis, ACL tears, and osteoarthritis. One therapeutic approach to address the pain has been electrical stimulation. This is a non-invasive treatment that introduces electrical currents into the injured tissue or muscle. However, there are several modalities of electrical stimulation treatment that include Transcutaneous Electrical Nerve Stimulation (TENS), Neuromuscular Electrical Stimulation (NMES), and Patterned Electrical Neuromuscular Stimulation (PENS). These treatments have the same goal: to provide a non-invasive method to stimulate the muscles and nerves to aid the healing process. Throughout this research, the populations targeted were females and males with age ranging from adolescents to older adults. The subjects were 15 – 75 years of age and had experienced knee injuries. They included athletes, older adults with osteoarthritis, and those who required arthroplasty. Between January 2023 and April 2024, the review of literature was conducted using UCF Libraries, PubMed, (MedLine), and SPORTDiscus (EBSCOhost). Keywords used included “TENS (Transcutaneous Electrical Nerve Stimulation) *”, “NMES (Neuromuscular Electrical Stimulation) *”, “osteoarthritis (OA)*”, Electrical Stimulation (E- Stim) *”, “knee injuries*”, “pain management*”, “before exercise*”, “after exercise*” and “during exercise*”. The results from these studies suggested that the application of e-stim was favored either during or after exercise.

Thesis (MSpor)--University of Stellenbosch, 2007. / ENGLISH ABSTRACT: Various types of post-exercise recovery strategies have become part of the modern athlete’s daily routine. It is a well known that inadequate recovery will prolong the time it takes for the runner’s body to adequately adapt between training sessions and competitions. Anecdotal claims have been made about compression garments as a beneficial method to assist recovery after training sessions and competitions. Until now limited scientific research has addressed the influence that compression garments have on the recovery process after sporting activities. The benefits of compression garments, as a possible recovery modality, are that it is costeffective, practical and easily obtainable. This study endeavored to investigate the possible influence that compression garments may have on middle-aged long distance runners’ recovery rate after a prolonged run. This is the first study that has focused on compression garments as a post-exercise recovery modality for experienced middle-aged long distance runners. The other unique aspect of this study is the prolonged two-hour treadmill protocol that was used to induce muscle soreness. In addressing the aims, a randomized, crossover study design was used to investigate the possible benefits that the high pressure (CCL II 23-32 mmHg (mercury millimeter)) graduated compression garments may bring about. Seven competitive male long distance runners (height: 176.0 ± 8.6 cm; body mass: 92.5 ± 11.8 kg; VO2max: 45.7 ± 5.0 mL.kg-1.min-1) between the ages of 36 to 51 years volunteered for the study. The runners had to complete a two-hour treadmill run at 70 % of their predetermined maximum aerobic capacity, followed by a monitored 72-hour recovery period. The first part of the prolonged run was a 90–minute variant gradient run, followed by a 30-minute downhill run. Each subject acted as his own control and visited the Stellenbosch University’s Sport Physiology Laboratory (South Africa) on two occasions, separated by 7 to 28 days. One test was done with a compression garment (23 to 32 mmHg) and the other without. Testing included the measurement of lower limb circumferences (ankle, calf, mid- and proximal thigh), plasma lactate, lactate dehydrogenase and creatine kinase concentrations and the completion of subjective questionnaires on perceived muscle soreness (visual analog scale (VAS)). The lower extremities’ functional ability was determined with a time to exhaustion (TTE) step test, a vertical jump test (VJ) and modified sit-and-reach flexibility test. Preexercise measurements were taken and immediately after and during the 72 hour after the treadmill run and repeated for the second bout. The main outcomes of this study showed that the two-hour treadmill run induced delayed onset of muscle soreness, with and without the compression garment. Evidence of this was a significant rise in plasma creatine kinase (CKp) over the duration of both trials (P < 0.05). The compression garment significantly reduced swelling in the calf muscle (41.0 ± 0.2 vs. 41.5 ± 0.5 mm; P < 0.002). Runners showed a lower perceived muscular pain and discomfort while performing functional knee movements at 24 and 48-hours after the two-hour run with the compression garment (1.2 ± 1.6 vs. 3.8 ± 2.4 cm and 0.9 ± 1.8 vs. 3.0 ± 2.6 cm on VAS, respectively; P < 0.05). Significant differences in perceived muscle soreness between the WCG and WOCG trials were observed at 24-hours after the run during rest (0.1 ± 0.2 vs. 0.4 ± 0.8 cm; P = 0.02) and with stretching (1.9 ± 1.2 vs. 3.5 ± 2.5 cm on VAS P = 0.02). The perceived pain associated with pressure was significantly lower with the compression garment at 24 (307 %) and 48-hours (237 %) after the run (P < 0.05). Blood lactate levels were reduced during the acute phase of recovery at 10 (1.8 ± 0.5 vs. 2.2 ± 0.9 mmol.L-1; P = 0.05) and 30 minutes (1.8 ± 0.5 vs. 2.4 ± 0.4 mmol.L-1; P = 0.01) after the run, as well as plasma creatine kinase concentrations were statistically significantly lower at 24-hours (238.3 ± 81.3 vs. 413.3 ± 250.8 units.L-1; P = 0.005) after exercise with the compression garment. The two-hour treadmill run and the compression garment had no significant influence on the runners’ lower limb strength, power, endurance or flexibility (P > 0.05). Compression garments demonstrated the potential to enhance recovery after prolonged strenuous exercise in well trained middle-aged runners. In addition, runners did not experience additional fatigue from the moderate to high pressure garments. The effect of higher pressure compression garments on athletic performance and the psychological influence of the garment need further investigation. / AFRIKAANSE OPSOMMING: Verskillende tipes naoefening herstelstrategië, vorm deel van die moderne atleet se daaglikse routine. Dit is wel bekend dat onvoldoende herstel sal beteken dat die atleet se liggaam langer sal neen om aan te pas tussen inoefen sessies en kompetisies. Sekere bewerings word al gemaak omtrent die voordeligheid van kompressiesokkies tydens die herstelperiode na oefening sessies en kompetisies. Tot nou toe was daar beperkte wetenskaplike navorsing oor die invloed van kompressie sokkies of die herstel proses van sport aktiwiteite. Die voordeel van kompressie sokkies as ‘n moontlike herstelmetode, is dat dit koste-effektief, prakties en maklik verkrybaar is. Hierdie studie poog om ‘n ondersoek in te stel na die moontlike invloed wat kompressie sokkies op middeljarige lang-aftstandatlete se herstelperiode sal hê na ‘n verlengde hardloopsessie. Hierdie is die eerste studie wat konsentreer op kompressie sokkies as ‘n naoefenings hersteltegniek vir ervare middeljarige lang-afstandatlete. Die ander unieke aspek van die ondersoek is die langdurige tweeuur trapmeul protokol wat gebruik word om spierpyn te veroorsaak. Om die doel te bereik, is ’n lukrake oorkruis studie gebruik om ondersoek in te stel na die moontlike voordele van die hoë druk (CCL II 23-32 mmHg) kompressie sokkies. Hierdie sokkies toon ’n progressiewe verhooging van druk vanaf die enkle tot onder die knieskyf. Sewe mededingende langafstand atlete (lengte : 176.0 ± 8.6 cm; liggaams massa: 92.5 ± 11.8 kg; VO2maks: 45.7 ± 5.0 mL.kg-1.min-1) tussen die ouderdomme van 36 en 51 jaar, het aan die studie deel geneem. Die wedlopers moes ‘n twee-uur lange trapmeul toets voltooi, teen 70% van hul vooraf bepaalde maksimum aerobiese kapasiteit. Dit is gevolg deur ‘n gemonitorde 72-uur herstel periode. Die eerste deel van die twee-uur hardloop sessie was ‘n 90-minuut afwisselende opdraende en afdraende hardloop stel, wat gevolg is deur a 30-minuut afdraande deel. Elke deelnemer was sy eie kontrole en het op twee geleenthede die Stellenbosch Universiteit se Sport Fisiologiese Laboratorium (Suid Afrika) besoek. Die twee besoeke is tussen 7 en 28 dae geskei. Een toets is met kompressie sokkies gedoen (23 – 32 mmHg) en die ander sonder. Die toetse het die volgende behels: laer been omtrekke (enkel, kuit, middel- and bo dy), die versameling en ontleding van bloed monsters vir plasma laktaat, laktaat dehydrogenase and kreatine kinase konsentrasies en die voltooing van subjektiewe vraelyste oor die graad van spierpyn ervaaring (“visual analog scale” (VAS)). Die onderlyf funksionele vermoëns is bepaal met ’n tyd tot uitputtings traptoets, ‘n vertikale sprong toets en ‘n gewysige sit-en-strek soepelheids toets. Data is voor die oefeninge in gevorder asook direk daarna, en gedurende die 72 uur na die trapmeul draf. Die metings vir die tweede sessie is herhaal. Die hoof uitkomste van die studie het gewys dat die twee-uur trapmeulsessie het spierpyn veroorsaak, met en sonder die kompressie sokkies. Die bewys hiervan was ‘n betekensvolle toename in plasma kreatien kinase (CKp) oor die tydperk van albei oefening toetse (P<0.05). Die kompressie sokkies het die swelling in die kuitspiere verminder, in vergelyking met die toetse sonder kompressie sokkies (41.0 ± 0.2 vs. 41.5 ± 0.5 mm; P < 0.002). Wedlopers met die kompressie sokkies het minder spierseerheid en ongerief aangeteken toe hulle knie beweegings gedoen het op 24 en 48-uur na die twee-ure trapmeul toets (1.2 ± 1.6 vs. 3.8 ± 2.4 cm op VAS en 0.9 ± 1.8 vs. 3.0 ± 2.6 cm op VAS, onderskeidelik; P < 0.05). Betekenisvolle verskille is waargeneem tussen die toetse met en sonder kompressie sokkies, op 24-uur na die twee-ure toets gedurende rus (0.1 ± 0.2 vs. 0.4 ± 0.8 cm op VAS; P = 0.02) en met strek oefeninge (1.9 ± 1.2 vs. 3.5 ± 2.5 cm op VAS P = 0.02). Die pyn wat ervaar was met drukking, was betekenisvol minder met die kompressie sokkies op 24 (307 %) en 48-uur (237 %) na die trapmeul sessie (P < 0.05). Bloed laktaat konsentrasie in die sirkulasie was verlaag gedurende die akute fase van die herstelings periode op 10 (1.8 ± 0.5 vs. 2.2 ± 0.9 mmol.L-1; P = 0.05) en 30 minute (1.8 ± 0.5 vs. 2.4 ± 0.4 mmol.L-1; P = 0.01) na die hardloop sessie, sowel as die plasma kreatine kinase konsentrasie was statisties betekenisvol laer by 24 uur (238.3 ± 81.3 vs 413.3 ± 250.8 eenhede L-1; P = 0.005) na die hardloop sessie met die kompressie sokkies. Die twee-ure trapmeul toets en die kompressie sokkies het geen betekenisvolle invloed gehad op die wedlopers se onderlyf ledemate se plofkrag, uithouvermoë of soepelheid (P > 0.05) nie. Kompressie sokkies het gewys dat dit potensiaal het om met herstel te help na lang en harde oefening in geoefende middeljarige atlete. Nietemin is daar verdere wetenskaplike navorsing nodig om dit te bevestig. Wedlopers het nie addisionele vermoeienis van die drukking van kompressie sokkies ervaar nie. Sterker drukkende kompressie sokkies sowel as die sielkundige invloed van die sokkies benodig verdere navorsing.spierpyn ervaaring (“visual analog scale” (VAS)).

Thesis (MScSportSc)--Stellenbosch University, 2013. / ENGLISH ABSTRACT: There are extensive literature on the PEH response after acute and chronic aerobic and resistance exercise, as well as a few studies on concurrent and water exercise. However, there is comparatively little evidence that high intensity interval training (HIIT) elicits similar post exercise blood pressure reductions (PEH) compared to other types of exercise. Furthermore, it is difficult to quantify the magnitude of the hypotensive response following these exercises, due to variations in exercise protocols in terms of intensity and duration. Both these training variables are considered important determinants of the magnitude and duration of the PEH response. The current study determined the magnitude of the PEH response after an acute bout and six sessions of HIIT, and the effects after two weeks of detraining in overweight/obese young women. Twenty young women (aged 21 ± 2 years) volunteered for the study. All the subjects were normotensive (SBP: 119.2 ± 5.6 mmHg and DBP: 78.8 ± 4.1 mmHg). Subjects performed six sessions of HIIT within two weeks and detrained for two weeks. SBP, DBP, MAP and HR were monitored during seated recovery after exercise for 60 min to determine the change from resting values. The overall outcome showed that an acute HIIT session resulted in a reduction of 2.9 mmHg in SBP which approached near clinical significance, while six sessions of HIIT caused a clinically significant reduction of 5.3 mmHg; this response was almost totally reversed after detraining. There were no clinically significant reductions in DBP after the acute or six sessions of HIIT (1.7 and 2.7 mmHg, respectively). However, a clinically significant hypotensive response of 3.9 mmHg was sustained after detraining following the maximal exercise capacity test. MAP also reduced by a magnitude of 2.3 and 5.6 mmHg, respectively, after the acute bout and six sessions of HIIT, and detraining values were still 2.9 mmHg lower than resting values and approached near clinical significance. The results indicate that both an acute bout and six sessions of HIIT elicited a meaningful PEH response. However, the six sessions of HIIT caused a clinically significant reduction which was approximately twice the acute session. Likewise, detraining showed clinically significant effects in DBP and MAP, but SBP returned to near baseline values. This suggests that in only two weeks, the accumulated effects of six sessions of HIIT elicited a greater hypotensive response than after an acute session of HIIT. / AFRIKAANSE OPSOMMING: Daar is omvattende literatuur oor die post-oefening hipotensie (POH) na afloop van akute en kroniese aërobiese en weerstandsoefeninge, asook enkele studies oor gelyktydige krag- en uithouvermoë- en wateroefeninge. Daar is egter relatief min bewyse dat hoë intensiteit interval oefening (HIIO) soortgelyke post-oefening afnames in bloeddruk (POH) in vergelyking met ander tipes oefening veroorsaak. Voorts is dit moeilik om die omvang van die hipotensiewe respons na afloop van oefening te kwantifiseer, hoofsaaklik as gevolg van die variasies in oefeningprotokolle in terme van intensiteit en tydsduur. Beide hierdie inoefeningveranderlikes word as belangrike determinante van die omvang en die tydsduur van die POH respons beskou. Die huidige studie het die omvang van die POH respons na ʼn akute sessie en ses sessies HIIO, en die gevolge na afloop van twee weke se nie-inoefening (“detraining”) by oorgewig/vetsugtige jong dames, bepaal. Twintig jong dames (ouderdom 21 ± 2 jaar) het vrywillig ingestem om aan die studie deel te neem. Al die deelnemers was normotensief (SBD: 119.2 ± 5.6 mmHg en DBD: 78.8 ± 4.1 mmHg). Die deelnemers het ses sessies HIIO binne twee weke voltooi en het daarna vir twee weke geen inoefeningsessies gehad nie. SBD, DBD, GAD en HS is tydens ʼn sittende herstelfase vir 60 minute gemonitor om die verandering vanaf rustende waardes te bepaal. Die algehele uitkoms toon dat ʼn akute HIIO sessie ʼn afname van 2.9 mmHg in SBD tot gevolg gehad het wat aan kliniese betekenisvolheid grens, terwyl ses sessies van HIIO ʼn klinies betekenisvolle afname van 5.3 mmHg veroorsaak het; hierdie respons wat bykans volledige omgekeerd na die twee weke met geen inoefening. DBD het geen kliniese betekenisvolle afname na afloop van die akute of ses sessies van HIIO getoon nie (1.7 en 2.7 mmHg, respektiewelik). ʼn Klinies betekenisvolle hipotensiewe respons van 3.9 mmHg is egter gevind na die geen inoefeningsperiodes. GAD het ook met ʼn omvang van 2.3 en 5.6 mmHg, respektiewelik, verminder na afloop van die akute sessie en ses sessies van HIIO. Die geen inoefening waardes was steeds 2.9 mmHg laer as die rustende waardes en het aan kliniese betekenisvolheid gegrens. Die resultate toon dat beide ʼn akute sessie en ses sessies van HIIO ʼn betekenisvolle POH respons ontlok het. Ses sessies van HIIO het egter ʼn klinies betekenisvolle afname, wat ongeveer twee keer soveel as die afname van die akute sessie was, veroorsaak. In dieselde lig het ʼn twee weke geen inoefeningsperiode steeds klinies betekenisvolle veranderinge in DBD en GAD getoon, maar SBD het tot naby aan die basislyn waardes teruggekeer. Hierdie resultate suggereer dat in slegs twee weke die geakkumuleerde effekte van ses sessies van HIIO ʼn groter hipotensiewe respons as na ʼn akute sessie van HIIO ontlok het.

Objetivo: O presente estudo investigou as respostas hemodinâmicas agudas da pressão arterial sistólica (PAS), pressão arterial diastólica (PAD) e frequência cardíaca (FC), imediatamente e nas 24 horas após o exercício, em idosas hipertensas, submetidas a 3 tipos de exercícios físicos e um momento controle (C). Métodos: Participaram do estudo 30 idosas hipertensas sob terapia medicamentosa. Todas as idosas foram submetidas aos protocolos de exercício aeróbio contínuo (AC), exercício aeróbio intervalado (AI), exercício resistido (ER) e a (C), com o intervalo mínimo de 7 dias para assegurar o efeito agudo de cada intervenção, em ordem randomizada. Todas as participantes foram submetidas previamente ao teste ergométrico, utilizando-se o protocolo de rampa devido a sua melhor acurácia para a população em estudo. A prescrição do AC e do AI foi feita por meio da frequência cardíaca máxima (FCM) obtida no teste. Na intervenção do AC foi calculada a frequência cardíaca de treinamento (FCT), com a intensidade de 70% FCM, com duração de 40 minutos de exercício. No AI foi utilizado a alternância de 80% da FCM no período de condicionamento, durante 2 minutos, e 60% da FCM, durante 2 minutos, para o período de recuperação, com duração de 40 minutos de exercício. O ER foi conduzido após obtenção de uma repetição máxima (1RM) em três exercícios para os principais grupos musculares: chest press, leg press e remada sentada e mais seis exercícios resistidos comumente utilizados para a prescrição do treinamento de força nas academias, utilizando o número de repetições adequadas por meio da escala de percepção subjetiva de esforço (PSE). A intensidade do ER foi de 50% de 1RM para dez repetições para o aquecimento específico e, após 1 minuto, a carga era ajustada para 70% de 1RM e realizava-se uma série entre 6 e 10 repetições para o condicionamento em todos os exercícios. Os valores da PAS, PAD e FC foram obtidos antes e após as sessões dos exercícios pelo método oscilométrico e, após cada sessão era realizada a monitorização ambulatorial da pressão arterial (MAPA) de 24 horas nos 4 momentos. Os dados foram avaliados pelo modelo de efeitos mistos. Resultados: Os dados obtidos no período pré e pós exercícios, mostraram redução em menor valor da variável PAS após a realização do AI e AC comparados ao ER no momento pós exercício (p<0,01). Na FC foi observado aumento no período pós exercício em AI e AC em comparação com ER e de ER em relação ao C (p<0,01). As observações nas 24 horas subsequentes foram obtidas por meio da MAPA, com maior redução da PAS em AI nas 24 horas do que nos outros grupos, sendo a redução da PAS em ER também maior do que em AC e C (p<0,01). Na PAD, a redução em AI e ER foram similares. Considerando apenas o período de vigília, a redução de PAS em AI foi superior aos outros grupos. No período de sono, AI e ER promoveram maiores reduções na PAS, com maior redução da variável PAD em ER (p<0,01). Conclusão: A prática de exercício físico intervalado e resistido promovem maior hipotensão pósexercício (HPE) ao longo das 24 horas subsequentes, em relação ao AC e C. O exercício aeróbio contínuo promove apenas redução da pressão arterial nas primeiras horas após o exercício. / Objective: The present study investigated the acute hemodynamic responses of systolic blood pressure (SBP), diastolic blood pressure (DBP) and heart rate (HR), immediately and within 24 hours after exercise, in hypertensive elderly women submitted to 3 types of physical exercise and control. Methods: Thirty hypertensive elderly women in drug therapy participated of the study. They all underwent to continuous aerobic exercise (CA), interval aerobic (IA), resistance exercise (RE) and control (C), with a minimum interval of 7 days, in random order. All participants were previously submitted to the treadmill stress test, using the ramp protocol due to its better accuracy for the study population. The prescription of the CA and the IA was done by maximum heart rate (MHR) obtained by the test. In the CA intervention, training heart rate (THR) was calculated, with the intensity of 70% MHR, with duration of 40 minutes of exercise. In the IA, we used 80% of the MHR during the conditioning period for 2 minutes and 60% of the MHR during 2 minutes for the recovery period, lasting 40 minutes. The ER was conducted after obtaining a maximal repetition (1RM) in three exercises for the main muscle groups: chest press, leg press and seated paddling, and six more commonly used resistance exercises for the prescription of strength training in the academies, using the number of adequate repetitions through the subjective perception of effort scale (PES). The RE intensity was 50% of 1RM for ten replicates for the specific heating and after 1 minute the load was adjusted to 70% of 1RM, and a range of 6 to 10 replicates were performed for the conditioning. The SBP, DBP and HR values were obtained before and after the exercise sessions by the oscillometric method and after that, 24-hour ambulatory blood pressure monitoring (ABPM) was performed in the 4 moments. The data were evaluated by the mixed effects model. Results: Data obtained in the pre and post exercise period showed a decrease in the SBP variable after IA and CA compared to the RE (p <0.01). In the HR, we observed increase in the post-exercise period in IA and CA compared to RE and RE in relation to C (p <0.01). The observations in the subsequent 24 hours were obtained through ABPM, with a greater fall in SBP in IA in 24 hours than in the other groups, with a decrease in RE also greater than in CA and C (p <0.01). In DBP, IA and RE fall were similar. Considering only the waking period, the SBP decrease in IA was higher than the other groups. In the sleep period, IA and RE promoted fall in SBP, with a greater fall in DBP in RE (p <0.01). Conclusion: The practice of interval aerobic and resistance exercise promoted greater post-exercise hypotension (PEH) during the subsequent 24 hours, compared to CA and C. Continuous aerobic exercise promotes only drop in the first hours after exercise.
