Efeito agudo do exercício aeróbio com diferentes volumes no desempenho de força em indivíduos fisicamente ativos / Acute effect of aerobic exercise with different volumes on strength performance in physically active individuals

Silva, Natalia Ribeiro da 17 December 2015 (has links)
O treinamento concorrente (TC) é frequentemente utilizado por praticantes de atividades físicas e atletas com o intuito de desenvolver a força muscular e o condicionamento aeróbio. No entanto, essa estratégia de treinamento pode atenuar os ganhos de força e hipertrofia muscular em longo prazo, efeito este conhecido como fenômeno da interferência. Há indícios na literatura de que a magnitude da interferência pode ser dependente do volume em que o exercício aeróbio é realizado. Assim, o objetivo do presente estudo foi verificar o efeito do exercício aeróbio realizado com diferentes volumes no desempenho agudo de força máxima e de resistência de força dos membros inferiores. Homens fisicamente ativos (n=21) foram submetidos a seis condições experimentais realizadas em ordem aleatória, sendo três sessões de exercício aeróbio com volumes distintos (3km, 5km e 7km) seguidas pelo teste de força dinâmica máxima (1RM) e outras três sessões de exercício aeróbio com os volumes distintos seguidas pelo teste de resistência de força (4 séries de repetições máximas a 80% 1RM). Para o exercício aeróbio foi realizada a corrida contínua em esteira rolante a 90% do limiar anaeróbio (Lan) e os testes de força foram realizados no exercício leg press 45o. Para a comparação dos valores de 1RM, volume total (VT) e número de repetições máximas (NRM) da sessão de treinamento de força (TF) foi realizada uma análise de modelo misto tendo os volumes do exercício aeróbio como fator fixo e sujeitos como fator aleatório. Testes post-hoc com ajustamento de Tukey foram utilizados para comparações múltiplas. O nível de significância adotado foi de 5%. Não foram observadas diferenças nos valores de 1RM entre as condições. O VT e NRM das condições de 5km e 7km foram menores quando comparados com a condição controle. Ao passo que, o VT da condição de 7km foi menor em relação ao VT das condições de 3km e 5km; e o NRM da condição de 7km foi menor em relação ao NRM da condição de 3km. Não foram observadas diferenças no VT e NRM entre as condições de 3km e controle e entre as condições de 3km e 5km. Em conclusão, o desempenho da resistência de força foi prejudicado após a realização do exercício aeróbio e a ocorrência e a magnitude desta interferência dependeram do volume em que o exercício aeróbio foi realizado. Adicionalmente, o desempenho da força dinâmica máxima não foi prejudicado pela realização prévia do exercício aeróbio / Concurrent training (CT) is frequently utilized by physically active individuals and athletes in order to develop muscle strength and aerobic fitness. However, this training strategy may result in attenuation of the gains on strength and muscle hypertrophy in long term. This effect has been referred to as the interference phenomenon. There are indications that the magnitude of this interference may be dependent on the volume that aerobic exercise is performed. Thus, the aim of the present study was to verify the effect of aerobic exercise performed with different volumes on the acute performance of lower limbs maximum strength and strength endurance. Physically active men (n=21) were submitted to six experimental conditions performed in random order, three aerobic exercise sessions with different volumes (3km, 5km and 7km) followed by the maximum dynamic strength (1RM) test and three aerobic exercise sessions with different volumes followed by strength endurance test (4 sets of maximum repetitions at 80% 1RM). The aerobic exercise was a continuous treadmill run at 90% of the anaerobic threshold (AT) and all strength tests were performed in the leg press 45o. A mixed-model analysis with the volumes of aerobic exercise as a fixed factor and subject as a random factor was performed to compare 1RM values, total volume (TV) and maximum number of repetitions (MNR) of the strength training (ST) session. Post-hoc tests with Tukey adjustments were used for multiple comparisons. The significance level adopted was 5%. No differences were observed in 1RM values among conditions. The TV and MNR of the 5km and 7km conditions were lower when compared to the control condition. The TV of the 7km condition was lower than the 3km and 5km conditions; and the MNR of the 7km condition was lower than the 3km condition. No differences were observed in TV and MNR between the 3km and control conditions and between the 3km and 5km conditions. In conclusion, strength endurance performance was impaired when performed after aerobic exercise and the magnitude of this interference depended on the volume of the aerobic exercise. In addition, maximum dynamic strength performance was not affected by prior execution of aerobic exercise

Čižauskas, Mantvydas 22 May 2006 (has links)
The aim: to examine the alternation of physical preparedness of the cadets aged 23-25 of the Great Lithuanian etmon Jonusas Radvila training company, while purposely training the least trained physical feature. The object of the study: the physical preparedness of the cadets. Hypothesis: The results of the physical preparedness of the cadets will improve after 8 weeks of emphasized training of the least trained physical feature. Methods used in the work: theoretical analysis and generalization, anthropometry, physical fitness test, pedagogical experiment, mathematical statistics. Subjects: 54 healthy cadets, aged 23-25, of the Great Lithuanian etmon Jonusas Radvila training company. Anthropometrical measurements (height and weight) were performed using standard methods. The body mass index was calculated according to formula (kg/m2). The physical preparedness of the cadets was examined with the tests corresponding to the NATO standards: press-ups (t/2 min), sit-ups (t/2 min), and 3000 m running. Physical preparedness was assessed according to the table of points in the system of 5 points. After analyzing the results of physical preparedness it was observed that for those cadets who failed or performed weakly, the hardest exercise was sit-ups in 2 minutes. The experimental group of the cadets was made of volunteers, who failed or performed this normative of physical preparedness weakly. The program for training the dynamic endurance strength of abdominal muscles was applied... [to full text]

Physiological Adaptations Following a Strength Endurance Training Block Performed with Accentuated Eccentric Loading or Traditional Resistance Training

Long, Alex 01 May 2024 (has links) (PDF)
Physiological adaptations were investigated following a strength-endurance (S-E) block prescribed with accentuated eccentric loading (AEL) or traditional resistance training (TRAD). Recreationally trained participants (n = 11 males, 6 females, age = 23.2 ± 4.2 yrs, body mass (BM) = 81.3 ± 22.2 kg, height = 172.1 ± 10 cm) completed a four-week block of concurrent resistance, sprint, and change of direction training. Participants were assigned one of two training conditions, AEL (n = 9) or TRAD (n = 8). Training was identical, except AEL performed 110% eccentric overloading every 1st, 3rd, 5th, 7th, and 9th repetition during back squat (BS) and bench press (BP). Body composition, summated muscle size (ACSAsum) and thickness (MTsum), regional ACSA and MT, and region-specific fascicle angle (FA) and length (FL) were assessed pre- (PRE) and post-training (POST). External work was calculated and exercise displacement was measured to determine the mechanical stimulus provided. Physiological variables were analyzed using multiple mixed analysis of variance (ANOVA). External work and displacement were analyzed with independent Welch’s t-tests. A statistically significant main effect of Time was observed for ACSAsum and ICW (p < 0.05); however, there were no statistically significant Time x Condition interaction effects observed for any dependent variable (p > 0.05). Time x Length interaction effects also failed to reach statistical significance for regional ACSA or regional MT (p > 0.05). Moreover, Time x Position interaction effects were not statistically significant for regional MT (p > 0.05). There were also no statistically significant interaction effects observed for regional FA or FL (p > 0.05). Differences in external work did not reach statistical significance (p > 0.05). A four-week S-E training block, performed with or without AEL, increases muscle size, but results in only minor architectural alterations. Additionally, AEL appears to induce unique region-specific hypertrophy. In contrast, TRAD seems to induce greater increases in ICW, potentially indicating greater sarcoplasmic hypertrophy. Interestingly, 110% eccentric overloading did not lead to statistically greater work performed, although differences may be practically significant when allometrically scaled. Researchers and practitioners should examine region-specific musculoskeletal adaptations, when possible, to more accurately assess training effects.

OVLIVNĚNÍ EFEKTIVITY STIMULACE VYTRVALOSTNÍ SÍLY PROSTŘEDNICTVÍM CVIČENÍ NA NESTABILNÍCH OPORNÝCH PLOCHÁCH / Affecting the efficiency of stimulation a strenght endurance through exercies on unstable surface

Jebavý, Radim January 2012 (has links)
Affecting the efficiency of stimulation a strenght endurance through exercies on unstable surface In our work we sought to verify the affecting the efficiency of a Strength programme of exercise on unstable surfaces for stimulation of strength endurance abilities, compared to a similar didactic programme conducted on stable surfaces, thus creating an alternative choice for coaches, teachers, and sports instructors. A major element of the didactic process is the quality of the strength training programme on stable and unstable surfaces. When evaluating the overall results of the tests before and after the experimental programme, we come to be of the opinion that the experimental programme manifested itself positively in effectiveness of stimulating strength abilities. The strength programme had an influence on increasing the persistence of strength in dynamic and static regimens. In the case of a strengthening programme on unstable surfaces there was a tendency towards greater growth in the number of repetitions as opposed to programme on a stable base at the beginning of the programme in the case of exercise in a dynamic regimen. Keywords: effectiveness, strength endurance preparation, unstable surfaces, stabilisation system.

Lateralität bei Leistungsschwimmern

Hermsdorf, Mario 10 September 2009 (has links)
Kann durch ein zusätzliches Kraftausdauertraining bei Hochleistungsschwimmern eine vorhandene Lateralität bei den oberen Extremitäten verringert werden? Ein positiver Effekt des Trainings am Armkraftzuggerät (AKZ), welches mit unterschiedlichen Belastungseinstellungen für die beiden Seiten durchgeführt wurde, konnte nur bei zwei von den sieben Probanden (Pb.) der Testgruppe (TG) nachgewiesen werden. Die anderen Pb. der TG zeigten bei den gemessenen Parametern keine eindeutige Verringerung der absoluten bzw. prozentualen Differenzen, teilweise waren sogar Differenzvergrößerungen zu finden. Die Pb. der Kontrollgruppe (KG), die mit denselben Belastungseinstellungen für die beiden Seiten trainierten, zeigten ein sehr heterogenes Bild bei den erreichten Ergebnissen. Während bei sechs Pb. die erreichten Ergebnisse relativ stabil blieben, stiegen die Differenzen bei den anderen vier Pb. in unterschiedlichen Messungen an. Insgesamt kann keine signifikante Verringerung des anfangs vorhandenen Seitenunterschiedes bei der TG im Vergleich zur KG nachgewiesen werden. Bei einer nachträglichen Trainingsdatenanalyse des Schwimmers Pb. 18 konnte festgestellt werden, dass über den Zugstil Schmetterling (S) auf der linken Seite, wo höhere Belastungen eingestellt waren, auch höhere Leistungswerte provoziert wurden als bei der Zugart Kraul (K). Ferner waren die Leistungswerte beim S links größer als rechts, was bei K nicht der Fall war. Dort zeigte die rechte Extremität höhere Werte. Ob nun solch ein Training am AKZ mit dem Zugstil K oder S zu besseren Ergebnissen führt, konnte noch nicht geklärt werden. Aus diesem Grund wird ein Training in der Zugart der Hauptlage empfohlen. Außerdem sollte versucht werden, im allgemeinen Training spezielle Übungen zur Verringerung von Seitigkeitsunterschieden zu integrieren. / Introduction: The results of published studies on laterality (related to sport) as well as results of evaluations from IAT (Institute for Applied Sports Training) data and findings of own investigations indicate the existence of laterality in athletes, not only in acyclic but also in cyclical sports such as swimming. Is it possible to reduce existing laterality in upper extremities by additional strength endurance training in high performance swimmers? Results and discussion: A positive effect of swimming machine ergometer training, with different load settings for both sides, could be proven by only two out of seven subjects, whose side difference decreased demonstrably. The measured parameters didn’t show any significant decrease of the absolute and/or percentage differences for the other subjects, in fact an increase of side differences were to be found partially. The subjects of the control group, undergoing the same training, showed heterogeneous results. While the results of the six subjects remained stable, the side differences of the other four subjects increased during different measurements. Overall, there was no significant decrease of the existing laterality in the test group compared to the control group. In an additional training data evaluation of subject 18 it was found that the athlete’s left-hand side, where higher loads were set, was able to gain a higher performance in butterfly style than in crawl. In contrast to crawl style, the left side performance values during butterfly strokes were higher then right-hand side values. During crawls strikes the right-hand side displayed higher values. Whether a „crawl" or „butterfly" training at the swimming machine ergometer leads to better results, could not be clarified yet. For that reason, training in the athlete’s favored swimming position is recommended. Moreover, the general training program should imply certain exercises to decrease laterality.

­Hur påverkar dietärt nitrat muskelfunktionen och återhämtningen vid styrketräning? : En pilotstudie i samarbete med Karolinska Institutet och Åstrands laboratoriet.

Jakobs, Kristin January 2011 (has links)
Forskning om människans fysiologi och hur den fungerar uppdateras dagligen. Inom idrottens värld testas nya som gamla, naturliga som onaturliga preparat och träningsmetoder kontinuerligt, allt för att optimera en idrottares prestation. Ett ämne som det forskas mycket om idag är kvävemonoxid och dess påverkan i kroppen. Från att ha tolkats som ett skadligt ämne i kroppen har det gått till att möjligen kunna hjälpa hjärtsjuka patienter och även optimera idrottsutövande. Kvävemonoxid bildas i kroppen naturligt med hjälp av syre, men det kan även bildas utan syre genom intag av nitrat som hittas i många grönsaker. Studier om nitrat inom idrottsområdet har koncentrerats till dess påverkan vid uthållighetsidrott och effekten har visat på ökad verkningsgrad och blodflöde till muskulaturen. Senare fann forskarna även hur dietärt nitrat sänkte ens syreupptagningsförmåga (Vo2max) tillsammans med en ökad uthållighet. Detta är en intressant upptäckt då sänkt Vo2max ofta leder till en försämrad arbetsprestation. Dessa studier ger en bild av hur nitrat fungerar vid aerobt arbete, det vill säga med syre. Det som forskningen inte tagit upp ännu är hur nitrat påverkar anaerobt arbete och maximala prestationer som förekommer vid styrketräning. Syftet med denna studie var därför att undersöka hur nitrat påverkar muskelfunktion och uthållighet vid styrketräning.  I en randomiserad, dubbelblind, korsande studie, konsumerade åtta män (ålder 19-26, 23 (±2, 3)) nitrat eller placebo (0,1 mmol/kg kroppsvikt/dag) under tre dagar. Under fjärde dagen testades männens prestation i fyra olika styrketest. Laktat och glukosvärden mättes för att se hur den laktacida systemet påverkades. Studien gav inget stöd till att dietärt nitrat påverkar styrketräning. Resultaten från tillfället med nitrat respektive placebo förblev i stort sett oförändrade. Slutsatsen blev att ett intag av nitrat inte har någon större betydelse för denna modell av styrketräning. Den främsta förklaringen till detta kan tänkas vara att nitratet ger störst inverkan vid långvariga arbetsdurationer och främst under aerobt arbete. I detta fall används mestadels lagrad energi i kroppen, och energisystemen där syre krävdes är troligen inte av större betydelse. / Research on human physiology and how it is working is updated daily. In the world of sports they are testing new as old, natural as unnatural preparations and different training methods continuously in order to optimize athletic performance. A substance that´s been research on, up till today is nitric oxide and its influence in the body. From being interpreted as a harmful substance in the body, it went to possibly help heart disease patients, and also optimize the physic in sport performance. Nitric oxide is formed in the body naturally by oxygen, but it can also be formed without oxygen through the ingestion of nitrates found in many vegetables. Studies on nitrate in the sport field have concentrated on the effect on endurance sports and the effect has been shown to increase the efficiency and the blood flow to the muscles. Later on they also found that nitrate supplementation seems to give a lower Vo2max together with an increased time to exhaustion. These findings are really interesting because normally a reduction in Vo2max leads us to a decrease in workability. All these studies give an idea on how nitrate works aerobic, that is with oxygen. The research has not yet an explanation on how nitrate affect anaerobic work and maximum performance that occurs in weight training. The purpose of this study was to investigate how nitrate affects muscle function and endurance in strength training. In a randomized, double-blind, crossover trial, eight men (age 19-26, 23 (±2, 3)) consumed nitrate or a placebo (0.1 mmol/kg bodyweight/day) for three days. During the fourth day the test persons were tested in four different strength tests to see how they performed. Lactate and glucose concentrations were measured to see how the laktacid system was influenced. The study gave no support that dietary nitrate affects weight training. The results from the occasion with nitrate respectively placebo remained essentially unchanged. It was concluded that an intake of nitrate not will give any significant effects on the model of strength training. The main reason for this may be that nitrate provides the greatest impact on long-term work-duration and mainly during aerobic work. In this case the main use is mostly stored energy in the body, and the energy systems in which oxygen is required will probably not be of major importance. / Pilotstudie i samarbete med Åstrands laboratoriet och Karolinska Institutet

Efeitos do treinamento físico com kettlebell sobre a qualidade de movimento, força muscular e capacidade cardiorrespiratória

Castro, Bruno Farias 28 January 2016 (has links)
Fundação de Apoio a Pesquisa e à Inovação Tecnológica do Estado de Sergipe - FAPITEC/SE / Since it was introduced in the United States in 2001, Kettlebell training has grown exponentially among professional and amateur athletes from different sports. The main argument used by disseminators of this methodology was the fact that their ballistic exercises would be efficient to generate positive adaptations in muscle strength and power and cardiorespiratory endurance simultaneously, as well as being an extreme energy consumption activity. Such statements are currently supported by respected scientific publications however; it is not yet scientifically clear whether there is different adaptations between the two most common ways of practicing the swing, a fundamental exercise in Kettlebell training. Just as it´s unclear what is the best dose to prescribe for each goal during kettlebell training. Two studies were then developed with the following objectives: a) to compare the two most common forms of execution of the swing exercise, unilateral and bilateral (study one); b) to compare two typical kettlebell training routines with different volume and intensity (study two). Participated in this research physically active university students without experience (study one) or experience (study two) in kettlebell training. The results of our studies suggest that: a) the two forms of the swing exercise, unilateral and bilateral, are effective to improve the quality of motion muscle strength and cardiorespiratory endurance; b) Regardless of the volume and intensity used in the protocol of this study, the total training load was primarily responsible for the significantly positive response in the quality of movement, strength and cardiorespiratory endurance. / Desde que foi reintroduzido nos Estados Unidos em 2001, o treinamento com Kettlebell cresceu exponencialmente entre atletas profissionais e amadores das mais diversas modalidades. O principal argumento utilizado pelos disseminadores desta metodologia foi o fato de que seus exercícios balísticos seriam eficientes para gerar adaptações positivas na força e potência muscular e na resistência cardiorrespiratória simultaneamente, além de ser uma atividade de extremo consumo energético. Tais afirmações são atualmente suportadas por respeitadas publicações científicas entretanto, ainda não está claro cientificamente se existe diferentes adaptações entre as duas formas mais comuns de praticar o swing, exercício fundamental no treinamento com Kettlebell. Assim como, também não é de conhecimento científico, a dose de treinamento com kettlebell mais eficiente para que ocorram positivas adaptações nas capacidades físicas. Foram então desenvolvidos dois estudos com os seguintes objetivos: a) Comparar as duas formas mais comuns de execução do exercício swing, unilateral e bilateral (estudo um); b) Comparar duas típicas rotinas de treinamento com kettlebell com diferentes volume e intensidade (estudo dois). Participaram desta pesquisa estudantes universitários fisicamente ativos, sem experiência (estudo um) ou com experiência (estudo dois) em treinamento com kettlebell. Os resultados dos nossos estudos sugerem que: a) As duas formas de execução do exercício swing, unilateral e bilateral, são eficazes para melhorar a qualidade de movimento, a força muscular e a resistência cardiorrespiratória; b) Independentemente do volume e da intensidade utilizados no protocolo deste estudo, a carga total de treinamento foi o principal responsável pela resposta significativamente positiva na qualidade de movimento, na força e na resistência cardiorrespiratória.
