Background Positive affective responses can lead to improved adherence to exercise. This study sought to examine the affective responses and exercise intensity of self-selected exercise in adolescent girls. Methods An observational study where twenty seven females (Age M?=?14.6?�?0.8 years) completed three 20-minute exercise sessions (2 self-selected and 1 prescribed intensity) and a graded exercise test. The intensity of the prescribed session was matched to the first self-selected session. Intensity, affective responses and ratings of perceived exertion were recorded throughout the sessions and differences examined. Repeated measures ANOVAs were conducted to examine differences. Results There were no significant differences in intensity between the prescribed and self-selected sessions, but affective responses were significantly more positive (p?<?.01) during the self-selected session. Ratings of perceived exertion were significantly lower (p?<?.01) during the self-selected session than the prescribed session. On average participants worked at 72% V?O2 peak; well within the intensity recommended by the American College of Sports Medicine. Conclusion Even though the intensity did not differ between the self-selected and prescribed sessions, there was a significant impact on affective responses, with more positive affective responses being elicited in the self-selected session. This highlights the importance of autonomy and self-paced exercise for affective responses and may have potential long-term implications for adherence.
