Abstract:

The research examined the effects of different intensities and different rest intervals of strength training on the rating of perceived exertion (RPE) in young athletes. Participated in the study 23 young men, aged 17.06 ± .73 years, 68.01 ± 8.09 kg of body mass, and 173.65 ± 5.61 cm of height. They were submitted to the appropriateness of charges (5 RM, 10 RM or 15 RM) and rest intervals (30, 60 or 120 s) and then asked to point perceived exertion according to the OMNI-RES scale. A two-way ANOVA was used and significant differences were analyzed by post-hoc Bonferroni. For RPE there were no significant differences between the intensities in the recovery intervals evaluated. For intervals with the same intensity, there were differences between 15 RM and range of 120 and 60 s with 15 RM and 30 s intervals. Intensities of 10 and 5 RM, in the range of 120 s showed significant differences. It follows that the smaller the rest interval the greater the levels of fatigue regardless of the number of repetitions performed in all intensities and it may be inferred that the RPE was sensitive to reduction in the rest interval. A pesquisa analisou os efeitos de diferentes intensidades e diferentes intervalos de recupera o do treinamento resistido na percep o subjetiva de esfor o (PSE) em atletas jovens. Foram selecionados 23 adolescentes, homens, com 17.06 ± .73 anos de idade, 68.01 ± 8.09 kg massa corporal e 173.65 ± 5.61 cm de estatura. Submetidos à adequa o de cargas (5 RM, 10 RM ou 15 RM) e intervalo de recupera o (30, 60 ou 120 s), onde ao final de cada série foi pedido para apontar o esfor o percebido na escala OMNI-RES. A estatística utilizada foi a two-way ANOVA. As diferen as significativas foram analisadas pelo post-hoc de Bonferroni. Na PSE n o foram encontradas diferen as significativas entre as intensidades nos intervalos de recupera o avaliados. Com rela o aos intervalos com a mesma intensidade, verificou-se diferen a entre 15 RM e intervalo de 120 e 60 s com 15 RM e intervalo de 30 s. Para as intensidades de 10 e 5 RM, apenas o intervalo de 120 s apresentou diferen a em rela o a 5 e 10 RM com intervalo de 30 s demonstrou que entre as intensidades e intervalos de recupera o ocorreram diferen as significativas. Conclui-se que quanto menor o intervalo de recupera o maior ser o os níveis de fadiga, independente do número de repeti es executadas em todas as intensidades, podendo inferir que a PSE mostrou-se sensível a diminui o do intervalo de recupera o.
