The purpose of this study is to determine the relationship between task and ego goal orientation and ZOF. The subjects consisted of interscholastic athletes of the men's varsity and junior varsity baseball, men's track and field, and women's track and field teams from a local Midwestern high school. By providing a more concise zone of optimal function (ZOF) by breaking down the zone into three components: psychological, physiological, and competitive (evaluated by the Sport Participation Questionnaire) the athletes may be able to manipulate their ZOF by using the characteristics of their task and ego orientation (evaluated by the TEOSQ). The data was analyzed by doing a series of factor analyses and multiple regressions. After finding four significant factors (two separate psychological, one physiological, one competitive) a multiple regression was employed to determine the relationship between the factors and task and ego orientaXon.Nearly significant was the regression with ego-oriented athletes and the thinking construct which consisted of items 16-18 of the Sport Participation Questionnaire. Also, significant were relationships of the task or ego score and the demographic findings.
