Resistance exercise of high velocity contract muscular in older women : effects on perceived exertion.

O presente estudo comparou a percep??o subjetiva de esfor?o (PSE), atrav?s da escala de PSE OMNI-RES, em diferentes protocolos de exerc?cio resistido de alta velocidade de contra??o muscular. Doze mulheres idosas (63 ? 3,0 anos) realizaram tr?s protocolos de exerc?cio resistido, para membros superiores e inferiores. Cada protocolo foi feito com 3x10 repeti??es, com a carga de dez repeti??es m?ximas (tr?s s?ries de dez repeti??es cont?nuas); tr?s s?ries de dez repeti??es descont?nuas (cinco segundos de pausa); tr?s s?ries de dez repeti??es descont?nuas (quize segundos de pausa). N?o foi observada diferen?a significativa (p > 0,05) entre os tr?s protocolos. A reprodutibilidade da OMNI-RES entre os testes foi forte e positiva em ambos os exerc?cios. Comparada ? 1? s?rie, a PSE aumentou continuamente (p < 0,05), ap?s a 2? e 3? s?ries, em todos os protocolos. Conclui-se que: 1) A PSE foi a mesma, independentemente do protocolo; 2) A escala OMNI-RES de PSE ? reprodut?vel; e 3) A PSE foi maior com o aumento do n?mero de s?ries.This study compared measures of Rating of Perceived Exertion (RPE), based on the OMNI-RES RPE scale, to three different high-velocity resistance exercise protocols. Twelve older women (63 ? 3.0 yrs) performed 3 upper and lower body resistance exercise protocols. Each protocol involved 3X10 rep sets at a 10 repetition maximum load (3 sets of 10 continuous reps); 3 sets of 10 discontinuous reps (5 second rest interval); 3 sets of 10 discontinuous reps (15 second rest interval). No significant (p > 0.05) difference on RPE was observed among the three protocols. OMNI-RES reliability between tests was easy and positive in both exercises. Compared to baseline, RPE increased continuously (p < 0.05) after the second and the third set in of all the protocols. It was concluded that: 1) RPE is the same independent of the protocol; 2) the OMNI-RES RPE scale is reliable; and 3) RPE increase as the number of sets
