ABSTRACT

O objetivo deste estudo foi verificar o comportamento da força muscular após três semanas de destreinamento em adultos jovens. Dez homens (22,5±5,5 anos) ativos, saudáveis e experientes no treinamento de força realizaram o teste de 10RM nos exercícios leg press, supino reto e rosca scott, pré e pós um período de três semanas de destreinamento. Para a análise dos dados foi utilizado o teste não paramétrico de Wilcoxon, o nível de significância mantido em 5% e as análises realizadas no software SPSS 15.0. Não foi verificada diferença significativa em nenhum dos exercícios no pré e pós teste (leg press: pré 294,4±46,7, pós 316,7±51,7 kg; supino reto: pré 58,5±8,1, pós 59,4±9,9 kg; rosca scott: pré 31,2±2,3, pós: 31,8±3,9 kg). Entretanto, no leg press e rosca scott houve um incremento da força de 7,8 e 3,2%, respectivamente. Pode-se concluir que não existe alteração na força muscular após três semanas de destreinamento.


The aim of this study was to investigate the behavior of the muscle strength after three weeks of detraining in young adults. Ten active, healthy and experienced in strength training men (22.5±5.5 years), performed 10RM test in leg press, bench press and arm curl exercises, before and after a period of three weeks of detraining. Data was analyzed with nonparametric Wilcoxon test, the significance level was maintained at 5% and the analysis performed in SPSS 15.0. There was no significant difference in exercises in pre and post test (leg press: pre 294.4±46.7, post 316.7±51.7 kg, bench press: pre 58.5 ± 8.1, post 59.4 ± 9.9 kg; arm curl: pre 31.2±2.3, post: 31.8±3.9 kg). However, there was a strength increase of 7.8 and 3.2% in the leg press and arm curl respectively. In conclusion, was verified that no change in muscle strength happened after three weeks of detraining.
