The effect of trampolining activity on physical self-perception in junior secondary boys

In the past decades, most self-esteem intervention studies involved fitness training and adventure-based activities but not sport skill development programmes. In this study, 40 Chinese grade 7 boys took part in eight 2-hour trampolining sessions. Moderate increase in self-esteem was revealed (effect size = .46). The best and the worst learning outcomes were found in conditions that supported task-involvement (informing participants their performance ranks) and ego-involvement (informing participants their personal improvements) respectively, though no significant differences in skill proficiency were found in the participants. This study provided strong evidence for promoting task goals and suppressing ego goals in physical education.
