No limiar do humano : doping e performance esportiva em perspectiva antropológica

Silbermann, Marcos January 2014 (has links)
Esta dissertação tem como objeto as controvérsias instauradas a partir doping e o combate contra a sua utilização. Com o limite continuamente demarcado entre doping e antidoping, entre o lícito e o ilícito do esporte, os próprios limites do corpo, da natureza e do humano são traçados. Nesta direção desenvolver uma abordagem que descreva os coletivos sociotécnicos articulados a partir e através deste permanente conflito entre doping e antidoping é a via de entrada para uma melhor compreensão das relações entre esporte e tecnologia na atualidade. Seja, na performance atlética, que passa a ser compreendida como uma realidade intrinsecamente heterogênea a partir dos diversos artefatos sociotécnicos, conceituais e materiais envolvidos em sua constituição. Como nos contra investimentos realizados pelas instituições esportivas com o intuito de coibir e detectar as práticas de doping. No intuito de apreender como estas relações complexas produzem diversos dispositivos técnicos e conceituais que atuam nas intersecções entre o esporte profissional e a tecnociência, constituindo novas práticas e saberes sobre o corpo do atleta. Por fim, tensionando o anthropos como figura conceitual, tanto eticamente, questionando o que sabemos e compreendemos como humano, como disciplinarmente, explicitando os limites metodológicos da análise antropológica, quando se estabelece como um empreendimento disciplinar, que visa à compreensão do humano. / This dissertation has as its object the controversies brought from doping and combating its use.

The Effects of Attentional Focus and Dual-Tasking on Conventional Deadlift Performance in Experienced Lifters

Chan, Alan 07 January 2019 (has links)
Previous attentional focus literature suggests that adopting an external focus (EF) results in greater force production through a variety of mechanisms. The purpose of the present study was to examine the effects of attentional focus and dual-tasking when performing heavily loaded barbell movements that are specific to strength-based sports. Fifteen resistance-trained males (age = 23.3 ± 3.4 years) reported to the laboratory for three visits. The first visit consisted of a five-repetition maximum (5RM) test on the conventional deadlift. During the subsequent sessions, the participants performed a total of twelve single conventional deadlift repetitions while adopting an internal focus (IF), an external focus (EF), or while performing the cognitive task (COG). The IF and EF consisted of focusing on activating the quadriceps and maintain a straight bar path, respectively. The COG consisted of counting the total occurrence of two single-digits in a sequence of three-digit numbers, separately. Three-dimensional motion capture and force platforms were used to collect kinematic and kinetic data. No significant differences were found between the IF, the EF and the COG for lift duration, peak barbell velocity, peak vertical ground reaction force, area of 95% confidence ellipse, peak hip moments and peak hip powers. Adopting an EF significantly reduced variability of the barbell trajectory and centre of pressure (COP) in the anterior-posterior direction. Mean velocity of COP was also significantly lower for the EF. Our findings suggest that adopting an EF may lead to greater postural stability when performing heavily loaded barbell movements.

Nutrition and athletic performance: implications of heart rate variability

Minnis, James Michael January 1900 (has links)
Master of Science / Department of Human Nutrition / Mark Haub / The purpose of this review is to examine the role of heart rate variability (HRV) as a predictor of athletic readiness and performance and assess whether nutrition strategies can be implemented to create favorable HRV indices with the goal of improving athletic readiness and performance. The balance between training and recovery is crucial for reaching an optimal adaptation and avoiding overtraining, allowing for improved readiness to train and compete. The measurement of HRV is non-invasive and is used primarily to quantify physical and mental stress in athletes by monitoring the effects of the autonomic nervous system on the heart. Current data suggests a relationship between resting parasympathetic tone, via time and frequency domains, and athletic performance. Parasympathetic modulated HRV indices have been associated with performance metrics such as peripheral work capacity, aerobic power, running and sprint performance, swimming performance, weight lifting performance, anaerobic capacity, strength, and enhanced mental focus/skill execution. The use of nutrition to help enhance sports performance is becoming more common. Evidence-based sports nutrition provides fuel for training/competition, assists in maximizing training adaptations, enhances recovery, improves mental focus, and aids in injury prevention and recovery. The use of nutrition strategies to influence HRV is novel and current evidence is scarce in regards to nutritional effects on HRV, specifically in athletes. Current research suggests that achieving energy balance and decreasing body fat in overweight/obese individuals has positive effects on the vagal component of HRV indices. Proper hydration, fruit and vegetable intake, a moderate carbohydrate diet, omega-3 fatty acid supplementation/intake also seem to have positive effects on HRV indices. Certain individual supplements have been studied in regards to HRV including casein hydrolysate, amaranth oil, and bovine colostrum. Caffeine seems to have the opposite effect on HRV indices, increasing sympathetic modulation while decreasing parasympathetic modulation. Much more research needs to be done in regard to potential nutritional influences on HRV so that sport dietitians feel confident in the methods currently used to assess athlete readiness and determining what types of nutrition strategies may be used to further improve the performance of an athlete.

No. of bitstreams: 1 GilmarioRB.pdf: 219927 bytes, checksum: d54da309fb4e81072769d636df525c12 (MD5) Previous issue date: 2008-05-15 / The kinanthropometric characteristics are used by the sports science as selection criteria and detection of talents. Hence, this study aimed at comparing the anthropometrical profile, the body composition, the somatotype and the vertical jumps of the beach volleyball players. This study consists of 79 male beach volleyball players, being forty nine (n=49) Brazilian participants of the National Circuit and thirty (n=30) of 15 countries participating in the XV Pan American Games. In order to analyze the vertical jumps of the Brazilian the participants were allocated into two groups (G1 and G2) in agreement with the national ranking of their teams. The vertical jump protocol developed by Smith and collaborators was used to evaluate the vertical jumps of spike and block. The Heath-Carter anthropometrical technique (1990) was used for calculating the somatotype. The Student s t test with the Bonferroni adjustment was used to calculate the differences among the investigated variables. The multiple regression analysis was used to identify the contributions of the anthropometrical variables in the performance of the vertical jumps and the multivariance analysis was used to calculate the differences among the components of the somatotype. The Brazilian athletes of G1 were better than G2 in the spike jump (p <0.01), block jump (p <0.01) and in the block difference (p <0.01). The prediction model of the spike jump of G2 included the body mass and standing spike reach (adjusted R2 = 0.77), the body mass and the standing block reach were also included in the model of the block jump (adjusted R2 = 0.73). The regression model of G1 was not statistically significant. As for the somatotype, statistically significant differences were found between the Brazilians and the Pan Americans (Wilks' lambda = 0.498; p <0.05). The Brazilian somatotype was classified as balanced mesomorph (2.7-4.3-3.0) and the Pan American somatotype as endomorphic mesomorph (3.5-4.6-2.4). As to the specific position of the block game (2.8-4.3-2.9) and the defense game (2.6-4.4-3.0), the Brazilian somatotype was classified as balanced mesomorph and the Pan American somatotype, the block (3.7-4.4-2.4) and the defense (3.4-4.9-2.3), was classified as endomorphic mesomorph. In conclusion, the vertical jump height (spike and block) influences the male Brazilian beach volleyball players performance. The physical type of the Brazilian blockers and defenders was similar with relationship to the somatotype. The Brazilian and Pan American beach volleyball players differ in terms of kinanthropometric characteristics. This work had a multidisciplinary feature with the participation of several departments and laboratories, like the Physiotherapy Department, the Nutrition Department, the Physical Education Laboratory, thus corroborating the multidisciplinary research feature / As caracter?sticas cineantropom?tricas s?o utilizadas pela ci?ncia do esporte como crit?rios de sele??o e detec??o de talentos. Dentro deste contexto, este estudo teve como objetivo comparar o perfil antropom?trico, a composi??o corporal, o somatotipo e os saltos verticais de atletas de voleibol de praia. Participaram do presente estudo 79 atletas de voleibol de praia masculino, sendo quarenta e nove (n=49) brasileiros participantes do Circuito Nacional e trinta (n=30) de 15 pa?ses participantes dos XV Jogos Pan Americanos. Para analisar os saltos verticais dos brasileiros os sujeitos foram alocados em dois grupos (G1 e G2) de acordo com o ranking nacional dos seus times. Utilizou-se o protocolo de saltos verticais de Smith e colaboradores, para avaliar os saltos verticais de ataque e bloqueio. A t?cnica antropom?trica de Heath e Carter (1990) foi utilizada para o c?lculo do somatotipo. Teste t de Student com ajuste de Bonferroni foi utilizado para calcular diferen?as entre as vari?veis investigadas. A an?lise de regress?o m?ltipla foi utilizado para identificar as contribui??es das vari?veis antropom?tricas na performance dos saltos verticais e a an?lise multivariada de vari?ncia foi utilizada para calcular diferen?as entre os componentes do somatotipo. Os atletas brasileiros de G1 foram maiores no salto de ataque (p<0,01), salto de bloqueio (p<0,01) e na diferen?a de bloqueio (p<0,01) do que G2. O modelo de predi??o do salto de ataque de G2 incluiu a massa do corpo e a envergadura de ataque (R2 ajustado= 0,77) e tamb?m no modelo do salto de bloqueio foi inclu?do a massa do corpo e a envergadura de bloqueio (R2 ajustado= 0,73). O modelo de regress?o do G1 n?o foi estatisticamente significante. Quanto ao somatotipo foram encontradas diferen?as estatisticamente significantes entre brasileiros e pan americanos (Wilks lambda= 0,498; p<0,05). O somatotipo dos brasileiros foi classificado como mesomorfo balanceado (2,7-4,3-3,0) e o dos Pan Americanos como mesomorfo endom?rfico (3,5-4,6-2,4). Quanto ? posi??o espec?fica de jogo de bloqueio (2,8-4,3-2,9) e de defensa (2,6-4,4-3,0) o somatotipo dos brasileiros foi classificado como mesomorfo balanceado e o dos pan americanos de bloqueio (3,7-4,4-2,4) e defesa (3,4-4,9-2,3) foi classificado como mesomorfo endom?rfico. Em conclus?o, a altura do salto vertical (ataque e bloqueio) influencia a performance de atletas de voleibol de praia masculino brasileiros. O tipo f?sico dos bloqueadores e defensores brasileiros foi similar quanto ao somatotipo. Os atletas brasileiros e pan americanos de voleibol de praia se diferenciam quanto ?s caracter?sticas cineantropom?tricas. O trabalho teve um car?ter multidisciplinar com a participa??o de v?rios departamentos e laborat?rios, como o Departamento de Fisioterapia, Departamento de Nutri??o, Laborat?rio de Educa??o F?sica, atestando-se o car?ter multidisciplinar da pesquisa

Coordenação de Aperfeiçoamento de Pessoal de Nível Superior - CAPES / BACKGROUND:Basketball has intensive and intermittent efforts, however, is unclear, in which they compose affect technical-tactical performance. AIM: To comparethe technical-tactical performance after the high-intensity effort in college basketball players. METHODS:Ten male college basketball team athletes performed warm-up (5 min), followed or not from the Super-7 exercise, on different days. Shortly thereafter, the athletes performed two simulated 5v5 games lasting 10 min on different days:Light Pré-exercise Game (LGAME) vs. Vigorous Préexercise Game (VIGAME). A rating perception of effort for recordaded in the procedures and the internal load of the games was calculate. The technicaltactical performance was evaluate by: IAD-BB, and Basic and Advanced Game Statistics. The data of the athletes were groupedfor comparison between the simulated games.RESULTS: The RPE in the warm-ups were equivalent and VIGAME presented higher value for the LGAME (7.6 ± 1.1 and 5.7 ± 1.3 u.a.). There was no difference in overall technical-tactical performance according to specific IAD-BB components. During VIGAME there were fewer 3 point shots, assists, turnovers, field goal %, successful fastbreaks, points in the paint, drives, catch-and-shoot shots, lay-up %, field goals attempt, defensive rebounds. CONCLUSIONS:The high intensity pre-exercise did not influence the technicaltactical performance of basketball players. However,there was changing in the quality of the actions observed in the game statistics. / INTRODUÇÃO: O basquetebol possui esforços intensos e intermitentes, contudo, não é claro, em que medida eles afetam o desempenho técnico-tático. OBJETIVO: Comparar os efeitos de um esforço prévio de alta intensidade sobre o desempenho técnico-tático em jogadores de basquetebol universitário. METODOLOGIA: Dez atletas de equipe de basquetebol universitário do sexo masculinorealizaram aquecimento (5 min), seguido ou não do exercício Super-7, em distintos dias. Logo após, os atletas realizaram dois jogos simulados 5v5 com duração de 10 min cada, em dias distintos:Jogo de Estímulo Prévio Leve (JLEV) x Jogo Estímulo Prévio Vigoroso (JVIG). A percepção de esforço (PE) foi registradanos procedimentos e a carga interna dos jogos foi calculada. O desempenho técnico-tático foi avaliado por: Instrumento de Avaliação do Desempenho Técnico-Tático Individual no Basquetebol (IAD-BB), e as Estatísticas de Jogo Básicas e Avançadas. Os dados dos atletas foram agrupados para comparação entre os jogos simulados. RESULTADOS: A RPE nos aquecimentos foi equivalente e o JVIG apresentou maior valor que o JLEV (7,6 ± 1,1 e 5,7 ± 1,3 u.a.). Não houve diferença no desempenho técnico-tático geral, nos componentes específicos do IAD-BB. No JVIG houve menos arremessos de 3 pontos, assistências, bolas perdidas e aproveitamento dos arremessos de quadra, contra-ataques bem-sucedidos, pontos no garrafão, infiltrações com bola, arremessos do tipo catch and shoot, aproveitamento das bandejas, total de arremessos tentados e aumento nos rebotes defensivos. CONCLUSÃO: O esforço prévio de alta intensidade não interferiu no desempenho técnico-tático dos jogadores de basquetebol. Houve, no entanto, alterações na qualidade das ações observadas nas estatísticas de jogo. / São Cristóvão, SE

Avaliação da suplementação com extrato da folha de Erythroxylum mucronatum (Benth.) associada ao treinamento de força na melhora do desempenho físico de ratos / Evaluation of the Erythroxylum mucronatum (Benth.) leaf extract supplementation associated with a resistance training on enhance of physical performance of rats

Silva Filha, Elizabete 23 February 2018 (has links)
Coordenação de Aperfeiçoamento de Pessoal de Nível Superior - CAPES / A regular practice of physical activity and an adoption of a diet that supply the individual's metabolic needs are essential for good physical performance. The usage of natural products for this purpose is already described in the literature, mainly by the antioxidant effect. Erythroxylum mucronatum (EM) belongs to the family Erythroxylaceae, known for high concentrations of flavonoids and alkaloids, compounds that are characterized as antioxidants. Therefore, the objective of this study was to evaluate the effect of supplementation based on the ethanolic extract of EM (EEM) in the improvement of the physical performance of rats submitted to strength training. 40 Wistar rats (250-300g), divided into 4 groups: Control Group (GC), Trained (GT), Trained + EEM 50mg / kg (GTEM50), Trained + EEM 150 mg / kg . The trained animals were submitted to strength training for 4 weeks, 5x per week, with a volume of 3 sets with 10 repetitions and intensity 60% of a maximal repetition (1RM), the GC underwent a fictitious training. The body weight was monitored weekly and every 15 days the animals passed through rota-rod, grip strength and 1RM tests. At the end of the 4 weeks of training, the perigonadal and retroperitoneal fat, plantar muscles (MP) and blood were collected. After weighing, the MP was used to evaluate a lipid peroxidation (TBARS) and activity of the enzyme superoxide dismutase (SOD). Blood were used to measure the levels of alanine (ALT) and aspartate (AST) aminotransferase enzymes, biochemical markers of liver damage and concentration of creatine kinase (CK) and lactate dehydrogenase (LDH) enzymes. Finally, it was carried out the test of muscular resistance and measurements of glycemia (fast, pre, post and 15 ppp-test) and lactate (pre, post and 15 'post-test). Initially, it was identified the total phenolic compounds content (213,29 ± 5,58mg) and total flavonoids (355,73 ± 7,74mg) of the EEM. After 4 weeks of training, the GTEM150 had lower body weight when compared to the GC, in addition, GTEM50 and 150 presented lower amount of fat when compared to GC and GT. All groups presented higher weight of MP when compared to GC. On rota-rod, the GTEM150 showed better performance on the thirtieth day when compared to the GC. In grip strength test, the GTEM50 and 150 groups showed a better performance on the fifteenth day when compared to the GC and on the thirtieth day all the groups were superior to the GC, in addition, the GTEM150 was superior to GT and GTEM50 in the same day. In the 1RM, on the fifteenth day all groups obtained superior results to the GC and on the thirtieth day the GTEM150 was superior to the GT and GTEM50. Regarding the muscular endurance test, it observed that all groups were superior than GC, however, GTEM150 was also better than GT and GTEM50. In addition, the GTEM150 presented lower hypoglycemic response during- and hyperglycemic after- the test. All trained groups had a lower post-test lactate concentration when compared to GC and 15 'post-test the GTEM50 recovered faster than GC and GTEM150 than all groups. In the PM, a lower lipid peroxidation was observed in all groups compared to GC and GTEM150 compared to the others. All groups had increased SOD activity when compared to GC, and GTEM150 an increased activity when compared to GT and GTEM50. In addition, GTEM150 presented lower concentration of CK and LDH in the plasma when compared to all the other groups. Finally, there was no difference in ALT and AST concentration levels. In summary, our results point to an improvement on physical performance in animals supplemented with MEE at a dose of 150 mg / kg. / A prática regular de atividade físicas e a adoção de uma dieta que supra todas as necessidades metabólicas do indivíduo, são fatores chave para um bom desempenho físico. A utilização de produtos naturais para este fim já é descrita na literatura, principalmente pelo efeito antioxidante destas substâncias. A Erythroxylum mucronatum (EM) pertence à família Erythroxylaceae, conhecida pelas grandes concentrações de flavonoides e alcaloides, compostos estes caracterizados como antioxidantes. Sendo assim, o objetivo deste estudo foi avaliar o efeito da suplementação a base do extrato etanólico de EM (EEM) na melhoraria do desempenho físico de ratos submetidos ao treinamento de força. Para tal, foram utilizados 40 ratos Wistar (250-300g), divididos em 4 grupos: Grupo Controle (GC), Treinado (GT), Treinado + EEM 50mg/kg (GTEM50), Treinado + EEM 150 mg/kg (GTEM150). Os animais treinados foram submetidos ao treinamento de força por 4 semanas, 5x por semana, com volume de 3 séries com 10 repetições e intensidade 60% de uma repetição máxima (1RM), o GC passou por um treinamento fictício. O peso corporal foi acompanhado semanalmente e a cada 15 dias os animais passavam por testes no rota-rod, grip strength e 1RM. Ao término das 4 semanas de treinamento, a gordura perigonadal, retroperitoneal, os músculos plantares (MP) e sangue foram coletados. Após pesado, o MP foi utilizado para avaliar a peroxidação lipídica (TBARS) e a atividade da enzima superóxido dismutase (SOD). O sangue foi utilizado para aferição dos níveis das enzimas alanina (ALT) e aspartato (AST) aminotransferase, marcadoras bioquímicas de danos hepáticos e concentração das enzimas creatina quinase (CK) e lactato desidrogenase (LDH). Por fim, foi realizado o teste de resistência muscular e medidas de glicemia (jejum, pré, pós e 15’pós-teste) e lactato (pré, pós e 15’ pós-teste). Inicialmente, identificamos o teor de compostos fenólicos totais (213,29±5,58mg) e de flavonoides totais (355,73±7,74mg) do EEM. Após 4 semanas de treinamento, o GTEM150 possuía menor peso corporal quando comparado ao GC, além disso, os GTEM50 e 150 apresentaram menor quantidade gordura quando comparados ao GC e GT. Todos os grupos apresentaram maior peso do MP quando comparados ao GC. No rota-rod, o GTEM150 apresentou melhor desempenho no trigésimo dia quando comparado ao GC. No grip strength os grupos GTEM50 e 150 apresentaram uma melhor performance já no décimo quinto dia quando comparados ao GC e no trigésimo dias todos os grupos foram superiores ao GC, além disso, o GTEM150 esteve superior que o GT e GTEM50 neste mesmo dia. No 1RM, no décimo quinto dia todos os grupos obtiveram resultados superiores ao GC e no trigésimo dia o GTEM150 foi superior ao GT e GTEM50. Em relação ao teste de resistência muscular, observamos que todos os grupos foram superiores ao GC, entretanto, o GTEM150 foi também melhor que o GT e GTEM50. Além disso, o GTEM150 apresentou menor resposta hipoglicêmica durante e hiperglicêmica após o teste. Todos os grupos treinados apresentaram uma menor concentração de lactato pós-teste quando comparado ao GC e 15’ pós-teste o GTEM50 se recuperou mais rápido que o GC e o GTEM150 que todos os grupos. No MP foi observado uma menor peroxidação lipídica em todos os grupos comparados ao GC e no GTEM150 comparado aos demais. Todos os grupos tiveram atividade da SOD aumentada quando comparado ao GC e o GTEM150 obteve maior atividade quando comparado ao GT e GTEM50. Ademais, GTEM150 apresentou menor concentração de CK e LDH no plasma quando comparado a todos os demais grupos. Por fim, não houve diferença nos níveis de concentração de ALT e AST. Em suma, nossos resultados apontam uma melhora do desempenho físico nos animais suplementados com EEM na dose de 150 mg/kg. / Aracaju, SE

Utför fotbollsspelare skadeförebyggande träningsprogram och har de tillgång till medicinsk personal? : - En enkätundersökning / Are soccer players performing an injury prevention program and do they have access to medical staff : - A questionnaire study

Fomin, Gabrielsen, Sanne January 2017 (has links)
Bakgrund: Det finns i tidigare studier beskrivna problem så som implementering och följsamhet när det gäller skadeförebyggande träningsprogram (SPP) för fotbollsspelare.   Syfte: Syftet med studien är att kartlägga och undersöka om kvinnliga och manliga fotbollslag i Stockholm utför ett SPP samt om det finns något samband med deras tillgång till medicinsk personal. Syftet är också att undersöka om det finns någon skillnad på tillgången till medicinsk personal och utförande av SPP mellan kvinnliga och manliga fotbollsspelare.   Metod: Enkäten skickades ut till 133 manliga och kvinnliga fotbollsspelare från samma fotbollsklubb. Enkäten innehöll 14 frågor om tillgång till medicinsk personal, information om skadeförebyggande träning samt utförande av SPP.   Resultat: Totalt 82 fotbollsspelare besvarade enkäten.  Majoriteten av deltagarna uppgav att de har tillgång till medicinsk personal. Fler manliga än kvinnliga fotbollsspelare har tillgång till medicinsk personal (P=0,018). Ingen korrelation visades mellan att ha tillgång till medicinsk personal och att ha fått information om skadeförebyggande träning (P=0,45). 66% av deltagarna angav att de utför ett SPP.
