ABSTRACT
ABSTRACT This study aimed to analyze how strength is measurement and its use occurs in studies of Latin American magazines with swimming athletes. The review followed PRISMA principles, carrying out the research in Scielo and Lilacs databases, adopting as inclusion criteria: a) studies with swimming athletes samples; b) studies that involved some evaluation of strength in athletes. A total of 87 articles were found, where 23 remained for complete analysis for suit all the criteria. Data analysis will be performed by metassumarization and content analysis. The results indicated the main measuring instrument to evaluate the strength was the dynamometer (isokinetic, isometric, and portable). Two main groups of subjects involved in the studies were identified, being these, the analysis of the strength for a better performance, and the analysis of imbalance muscular strength, especially in the shoulder. The intervention method was little used, demonstrating that the use of parachute during training and strength training outside the pool under an undulatory periodization are both effective in the athlete's performance. It is concluded that the main method of strength assessment in swimming is with the use of dynamometer, swimmers have a shoulder with muscular imbalance and there are few proposals for intervention to improve muscular strength in swimming athletes.
RESUMO O objetivo foi analisar como ocorre a mensuração da força e sua utilização em estudos de revistas latino-americanas com atletas de natação através de uma revisão. A revisão seguiu os princípios do PRISMA, realizando a pesquisa nas bases de dados Scielo e Lilacs, adotando como critérios de inclusão: a) estudos com amostras de atletas de natação; b) Estudos que envolveram alguma avaliação de força em atletas. Um total de 87 artigos foram encontrados, onde 23 permaneceram para análise completa por atenderem todos os critérios. Para análise de dados foi utilizado metassumarização e análise de conteúdo. Os resultados indicaram que o principal instrumento de medida para avaliar a força foi o dinamômetro (isocinético, isométrico, portátil). Dois grupos principais de temáticas envolvidas nos estudos foram identificados, sendo estes, a análise da força para um melhor desempenho e a análise do desequilíbrio da força muscular, especialmente no ombro. O método de intervenção foi pouco utilizado, demonstrando que o uso do parachute durante o treino e o treinamento de força fora da piscina sob uma periodização ondulatória são eficazes no desempenho dos atletas. Conclui-se que o principal método de avaliação da força na natação é com o uso do dinamômetro, os nadadores apresentam um ombro com desequilíbrio muscular e poucas são as propostas de intervenção para a melhora da força muscular em atletas de natação.
ABSTRACT
Aim: Determine the relationship between changes in oxidative stress markers, muscle damage, DOMS, and their relationship with performance in response to a session of football training during a 1-week recovery period of young football players. Methods: Nineteen young football players aged 16.7±1.0 years were included in the study. After initial evaluation for basal levels of oxidative stress and muscle damage markers, DOMS, and performance testing (Vertical Jump, Agility T-test, and RAST potency test), the athletes were submitted to a routine training session composed of squatting exercises, followed by a simulated football match of 45 minutes. Athletes were reevaluated for 3 consecutive days (24h, 48h, and 72h after the training session) during the recovery week. Results: An elevated DOMS score in the quadriceps and posterior thigh (P<0.05) and serum CK was observed 24h to 72h after the training session. Despite elevated DOMS and CK muscle damage markers, no changes were observed in the vertical jump test, RAST potency test, or agility T-test during the recovery week. In addition, no changes in the oxidative stress markers analyzed MDA, AOPP, and GSH were observed during the recovery week. Conclusion: Training sessions with squatting exercises and simulated matches promote a rise in CK and DOMS, but not sufficient to impair physical performance during the training week in young players.(AU)
