An important reason to aim for a high level of participation of girls and women in sport and development projects is that it can bring them the physical, psychological and social advantages of sport. Participation in sports activities, as long as it is organised with knowledge and skill, can bring not only better health but also discipline, self-awareness, self-confidence, independence and leadership skills. Women will often start to feel stronger both physically and psychologically. From a social point of view, they gain experience with teamwork, negotiating, planning, winning and losing. Sport also yields up social networks. This broadens a person's perspective; women learn more about their community and the world outside of it, and are able to identify opportunities they would otherwise not have been aware of. Because sport increases self-confidence, girls are better able to stand up for themselves. This is important for the prevention of unwanted sexual contacts and pregnancy. Sport is therefore a means in preventing HIV/AIDS.
