In South Africa, sport unites the country because it transcends race, gender, politics and language groups. Majority of South African youth are in the developmental phase where critical decisions are being taken on key life transitions, including education, work, lifestyle, participation in society, and other psycho-sociological areas. Learners in high school in the previously disadvantaged communities form a crucial part of South Africa’s future. The purpose of this study, therefore, was to determine how high school learners in the Theewaterskloof Municipality in South Africa perceived the influence of sport participation on their quality of life. The perceptions of the learners were specified according to six domains: drugs, alcohol and crime; mental health; social contact, culture and safety; happiness and wellbeing; physical health and diseases; and academic achievement. The research was conducted at three high schools located in the Theewaterskloof Municipality, Western Cape Province. A questionnaire was used to collect information from 484 learners aged 13 to 18 years. A significant relationship was noted for variables of each domain, except drugs, alcohol and crime and academic achievement. Learners perceived that increasing sport participation resulted in a significantly positive response of at least one variable for the domains social contact, culture and safety; physical health and diseases; mental health; and happiness and wellbeing.
