JEPonline 2013;16(6):79-88. This study investigated the perceptual and affective responses of different muscle actions during weight training in older women. Fourteen women between 60 and 75 yrs of age participated in this research. All subjects completed four exercise sessions. During the first session, maximum strength was determined (1RM) in the following exercises: lying supine, leg extension, front pulley, leg curl, and side lifting. In the second, third and fourth exercise sessions, concentric (CONC), eccentric (ECC), and dynamic (DYN) training were randomly performed. Rating of perceived exertion (RPE) and affective responses were determined after each series of exercises. To analyze RPE and affective responses between the exercises during the same training session, ANOVA with repeated measures was used with a significance level of P≤0.05. No significant effects were found for perceptual and affective responses between sessions with different muscle actions. Regarding exercises during the sessions, significant effects were found for RPE (F (4,52) = 6.272, P=0.003, n2 p = 0.325) only between exercises: supine x pulley (P=0.007) and leg extension x pulley (P=0.004) in ECC. The RPE and affective responses were similar between the different muscle actions. However, the ECC exercise sessions promoted better perceptual and affective responses (depending on the exercises used).
