Three groups of 40 college students were each given different treatments in an experiment designed to investigate the effect of systematic physical fitness training combined with counseling on measured self-concept. One experimental group received a fitness program consisting of flexibility training and systematic distance running; a 2nd group received the same physical training plus 1 hr/wk of group counseling designed to reinforce progress made in the fitness program; and a 3rd group (control) received no physical fitness training or counseling. After a 10-wk program, the group receiving fitness training and running made a significant gain in self-concept as measured by the Tennessee Self-Concept Scale. The Ss were divided into low and high self-concept groups for statistical analysis. It was found that the students who received fitness training and counseling and had low self-concepts on the pretest measure made significant positive changes in self-concept.
