- Abstract
The purpose of this study was to investigate the impact of self-selected and imposed exercise intensity on cardiorespiratory fitness and body composition in 75 obese women. The subjects were divided into: G1 (self-selected intensity); G2 (intensity 10% above ventilatory threshold); and G3 (control group, no exercise). The exercise program consisted of 12 wks. The findings demonstrated a significant improvement in cardiorespiratory fitness (VO2 max and HRVT) in G1 (3.55 mL.kg-1.min-1) and in G2 (9.69 mL.kg-1.min-1). There were no significant changes in body composition. In conclusion, the 12-wk program of self-selected and imposed exercises resulted in an improvement in cardiorespiratory fitness with no significant changes in body composition. The self-selected intensity demonstrated to be an important strategy in order to promote engagement of obese subjects in an exercise program.
