Self-report questionnaires consisting of psychological, social, and health/physical fitness variables, were administered to 319 males and 385 females aged 40 to 69 years to identify contributing variables to exercise motivation and sport participation of the middle-aged and elderly people.
　The correlation between such variables and exercise motivation or sport participation was computed. Means of the variables between typical groups classified by using the strength of exercise motivation and sport participation were compared. Multiple regression analyses were also applied to the data.
　Results seemed to show that contributing variables to both exercise motivation and sport participation were value of exercise and sport friends. Exercise time and health condition were also added to the effective variables of sport participation.
