They also see it as a way to relax and forget about social responsibilities, and find that encouraging family and peers to participate is very important (Nelson et al ., 2010). Although this is considered important, there are also obstacles. Some Indigenous Australians view leisure, sport and physical activity negatively, believing that they remove connections with others by focusing on oneself (Nelson et al., 2010). The final obstacle is family involvement; Indigenous Australians experience a lack of family activities (Nelson et al., 2010). Physical factors relate to an individual's physiology. Indigenous Australians have a high disease burden due to diseases such as diabetes, cardiovascular disease, respiratory disease and obesity (Nelson, Abbott & Macdonald, 2010, p. 498).
