AFFECTIVE RESPONSES TO PRESCRIBED AND SELF-SELECTED STRENGTH TRAINING INTENSITIES.

This study was an evaluation of the effects of self-selected intensity and three prescribed intensities of strength exercises on affective responses. 16 healthy active male participants (M age = 25.1 yr., SD = 5.5; M height = 168.0 cm, SD = 31.8; M weight = 84.4 kg, SD = 8.6) were randomly assigned to a control condition without exercise (Control); three prescribed exercise intensities at 40% of one-repetition maximum (1RM), 60% 1RM, and 80% 1RM; and one self-selected intensity (Self-selected). Affective response was assessed by the Feeling Scale and the Felt Arousal Scale. All prescribed intensities showed increased activation and only the session at 80% 1RM showed reduction valence compared to the Control condition. Thus, the affective response to strength training does not seem to be influenced by exercise intensity.
