- W1738768815 abstract "Acredita-se que o exercicio resistido (ER) em plataformas instaveis pode resultar em uma maior demanda para o sistema neuromuscular, aumentando a ativacao dos musculos estabilizadores do tronco, o que representa um estresse adicional aos musculos esqueleticos quando comparado com a superficie da plataforma estavel. O objetivo deste estudo foi o de comparar a percepcao subjetiva de esforco (PSE), atraves da escala OMNI-RES e o numero de repeticoes maximas (RM), realizada a 80% de 1RM no exercicio supino reto entre as superficies instavel e estavel. A amostra foi composta por 10 mulheres treinadas (idade 22,5 ± 3,30). O teste de 1RM foi aplicado para a previsao de acoes voluntarias maximas musculares (AVMM), descritos por Kraemer, Ratamess (2004). O supino reto no banco a 80% de 1RM ate a falha muscular concentrica, sem alterar o padrao de movimento, foi realizado 48h apos a previsao das AVMM e o supino reto na plataforma instavel (bola suica) 48h apos a plataforma estavel. Para comparacao da percepcao subjetiva de esforco ( OMNI-RES ) e o numero de repeticoes maximas em relacao ao teste na plataforma estavel e instavel, foi aplicado o ‘ t-test de Student ’ para amostras pareadas. Em todos os casos foi adotado um nivel de significância de 0.05. A analise estatistica foi realizada pelo software de processamento e analise estatistica Package for Social (SPSS Science , Chicago, EUA), versao 17.0. ABSTRACT Comparative study of maximum number of reps and perception subjective effort It is believed that resistance exercise on unstable platforms may result in a greater demand for the neuromuscular system, increasing the activation of the stabilizing muscles of the trunk, which represents an additional stress to the skeletal muscles compared with the surface of stable platform. The aim of this study was to compare the perceived exertion by OMNI-RES scale and the number of repetitions performed at 80% of 1RM in the bench press exercise between stable and unstable surfaces. The sample consisted of 10 trained women (age 22.5 ± 3.30). The 1RM test was applied for predicting maximal voluntary muscle actions (MVMA), described by Kraemer, Ratamess (2004). The bench press at the bank at 80% of 1RM until concentric muscular failure, without changing the movement pattern was performed 48h after the forecast of MVMA the bench press and the platform unstable (swiss ball) 48h after stable platform. For comparison of perceived exertion (OMNI-RES) and the number of repetitions regarding testing in stable and unstable platform, the 'Student t-test' was applied for paired samples. In all cases we adopted a significance level of 0.05. analysis was performed by processing and statistical analysis software Statistical Package for the Social Sciences (SPSS Science,Chicago,USA), version 17.0." @default.
