|Title:||Overall and differentiated session ratings of perceived exertion at different time points following a circuit weight training workout|
da Silva, LH
|Abstract:||Session ratings of perceived exertion (SRPE) have been considered to provide a quantitative evaluation of the entire exercise session in different types of resistance training. In this study we investigated the ability of SRPE to assess exercise strain in a circuit weight training (CWT) workout and the influence of time lag to report SRPE. Ten healthy male volunteers (22.3 +/- 2.8 years, 72.5 +/- 6.5 kg, and 175 +/- 5 cm) completed a CWT session involving three circuits of five multiple joint exercises with single sets of 20 repetitions at 30% one repetition maximum (1-RM). Heart rate [63.7-75.0% maximum heart rate (%HRmax)], blood lactate (5.6-7.6 mM) as well as overall, chest, and active muscle RPE increased significantly (p < 0.05) throughout the CWT, but no significant differences were found between ratings of perceived exertion (RPE) types. Overall, chest and active muscle SRPE were accessed 10 minutes, 20 minutes, and 30 minutes after the workout, with no significant main effects or SRPE type x time interaction being found (p > 0.05). Finally, no significant differences (p > 0.05) were observed between averaged SRPE and RPE responses (overall: 3.7 +/- 0.6 vs. 3.5 +/- 0.9; chest: 3.8 +/- 0.7 vs. 3.6 +/- 0.8; active muscle; 3.7 +/- 0.7 vs. 3.5 +/- 0.7). These results suggest SRPE, irrespective of the moment at which it is taken, to be a useful tool for assessing global exercise strain in a CWT workout, providing coaches, physicians, and exercisers a practical way for monitoring this type of resistance training.
