ALVES, Ragami Chaves et al. Weight exercise on affective and perceptual responses. Rev Bras Med Esporte [online]. 2015, vol.21, n.3, pp.200-205. ISSN 1517-8692.


Feelings of pleasure/displeasure are modulated according to prescribed exercise intensities, where the more intense the stimulus, the higher the perception of effort.


To investigate the differences between perceptual and affective responses to different intensities of acute resistance training in elderly women.


Fourteen women aged between 65 and 75 years old, previously sedentary and overweight were subjected to three different intensities of resistance training: 35% and 70% 1-RM, and self-selected. Affect and rate of perceived exertion (RPE) were assessed. Session rate of perceived exertion (RPE-S) was assessed 30 minutes after the conclusion of the session. One way ANOVA test for repeated measures was used for the dependent variables (RPE-S, RPE and affect), followed by Tukey's post hock.


RPE-S showed a significant difference (F (7.99) = 15.358; p = 0.001) between the intensities as well as RPE between each exercise. RPE-S of 35% 1-RM was lower when compared to RPE-S for 70% 1-RM, and self-selected intensity. The intensity of 70% 1-RM, compared with the self-selected intensity, showed no significant difference. Regarding RPE during the exercises, significantly more effort (p<0.001) was observed for the 70% 1-RM when compared with the self-selection of the load. The affect revealed a significant difference for the intensity of 35% 1-RM, showing a more pleasant response when compared to the load of 70% 1-RM, and self-selection of the load.


Results showed that low intensities are perceived as less effort and this fact contributed to the production of more pleasurable affective responses. Moreover, inter-individual factors between subjects can modulate these responses, enabling the reduction of perceived exertion in more vigorous intensities.
