RESUMEN
To investigate the relationship between cognitive and affective responses during acute exercise, 24 low-active females completed two 30-min bouts of cycle ergometer exercise at 90% of the ventilatory threshold. In one condition participants had full knowledge of the exercise duration (KD); in the other, exercise duration was unknown (UD). Affect and self-efficacy were measured before and every 3 min during exercise, and affect was also measured postexercise. Affect declined throughout the first half of both conditions, and continued its decline until the end of the UD condition, when a rebound effect was observed. Self-efficacy during exercise displayed a similar pattern. Hierarchical regression analyses demonstrated that during-exercise self-efficacy was a stronger predictor of during-exercise affect than preexercise self-efficacy, and that this relationship was strongest at the end of exercise when duration was unknown. These results indicate that repetitive cognitive appraisal of self and the task could impact the exercise experiences of low-active women during the adoption phase of an exercise program.

The purpose of this study was to examine the relationships between transformational and transactional leadership behaviors and the self-efficacy ofparticipants involved in a structured 10-week exercise program. Three weeksinto their exercise classes 174 females (M age = 25.36 years, SD = 8.48) provided ratings of their exercise instructor's leadership behaviors as well as their personal efficacy related to scheduling, over-coming barriers and within-class capabilities. Results revealed that for exercise initiates, contingent rewards behaviors were able to explain unique variation in scheduling self-efficacy and barrier self-efficacy, but not within-class self-efficacy. For experienced exercisers, none of the leadership behaviors assessed in this study were associated with participant self-efficacy.
