This study was designed to investigate the influences of family and peers on sport participation amongst adolescents in secondary schools at Hlanganani rural area of Limpopo Province, South Africa. A total of 172 learners (108 females and 64 males) attending three public secondary schools in Hlanganani rural area volunteered to participate in the study. Results indicated that adolescents preferred peers to family for support in sport participation. In terms of gender, no significant differences (p>0.05) were noted between mean values for school boys and girls with regard to family influence. Boys reported more tangible support, whereas girls indicated a preference for emotional support. Sport participation among learners is likely to increase when they receive informational, tangible, emotional and appraisal support from their parents and peers.
