JEPonline 2014;17(6): 66-73. The purpose of this study was to investigate the self-selected load for weight training and the sensations produced in obese adolescents. This study consisted of 11 obese adolescent women, 13 to 15 yrs of age with a body mass index ≥30.0 kg·m-2 . Each subject performed a 1 repetition maximum (1RM) test. The training session consisted of three exercises: (a) bench press; (b) leg press; and (c) barbell curl with 3 series of 10 repetitions at a self-selected intensity with a 1-min interval for rest. At the end of each series, the subjects reiterated their affective responses at that moment to the researcher. This procedure was adopted for all of the exercises. ANOVA was used for the comparison of affective responses between the different exercises. The findings indicate that the barbell curl presented a higher unpleasant affective response compared with leg press and bench press exercises. Weight training exercises at a self-selected intensity among obese adolescent girls promotes pleasurable affective responses.
