Background: Physical self-concept and physical self-esteem are important sources of general self-esteem and overall health. Evidence indicates that exercise leads to an enhancement in physical self-concept and physical self-esteem. Until now however, it remained unclear whether the beneficial effects of exercise were impacted by different types of exercise environments. Thus, the purpose of this study was to experimentally investigate, whether the presence or absence of an instructor or other group members influenced elder adults’ physical self-concept and esteem. Method: Participants were 46 women and 20 men (Mean age 65.4, SD = 4.36) who were randomly assigned to one of four experimental groups differing across two factors—group versus no-group and instructor versus no-instructor. Participants took part in an 8-week-walking program with a comparable number of training sessions across the four experimental groups. Physical self-concept and physical self-esteem were assessed both pre and post exercise intervention. Results: Descriptively, the highest improvement in physical self-concept and esteem were observed in the instructor/no-group and the no-instructor/group condition. Between these two conditions, no significant difference of change was observed. Moreover, no improvement was observed when both instructor and group were present. Conclusion: Effects of either instructor presence or group presence may be explained by mechanisms of social integration and social support. An unexpected absence of effects on self-concept and esteem under the instructor/group condition are explained with reference to an individual’s cognitive dissonance caused by the need to adapt to different exercise oriented goals or attitudes of the instructor and the group members which might hinder the positive development of the self.

Background： The influence of self-presentation concerns on the adolescent sport experience has received scant empirical attention. The purpose of this investigation was to prospectively examine the relationship among self-presentational concerns and pre-game affective states among middle and high school aged football players. Methods： American football players （n = 112; mean age = 15.57 years） completed a measure of self-presentational concerns （SPSQ, McGowan, et al., 2008） a week prior to the measurement of selected pre-game affective states （i.e., attentiveness, self-assurance, serenity, and fear）. Results： Regression analyses revealed that concerns about appearing athletically untalented negatively contributed to the significant prediction （p 〈 0.001） of pre-game attentiveness, /3 = -0.43, Radj ^2 19.5% （p 〈 0.001）, and self-assurance, /3 = -0.38, R^dj = 11.9% （p 〈 0.01）. Conclusion： These findings highlight the importance of reducing self-presentational concerns in promoting positive pre-game mental states that likely impact the quality of athletes＇ competitive play and experience.
