This study examined the moderating role of gender on the team building (TB)/perceived effort relationship in an exercise setting. Youths (n=100) who participated in either a TB or control group exercise setting completed a measure of perceived effort prior to and following a TB intervention. A 2 (group)×2 (gender) ANCOVA controlling for baseline perceived effort revealed a significant interaction, F (1, 95)=4.50, p<.05. The interaction revealed that females in the TB condition reported significantly more perceived effort at the post-assessment than did those in the control condition whereas the perceived effort reported by males did not differ between conditions. These results provide preliminary evidence that gender may need to be considered in future TB investigations that include perceived effort as a dependent measure.
