Hemophilia is a sex-linked recessive disorder characterized by a lack of blood factors necessary for clotting. This review aims to investigate the benefits of sports activities in children with hemophilia in terms of both physical and psychological wellness. Sports activity is necessary for children with hemophilia to preserve joints' range of motion, reduce joint bleeding, improve muscle mass and strength, enhance proprioception and prevent secondary chronic diseases. In the past, high-impact sports were usually forbidden in children with hemophilia because of their high bleeding risk. Recent studies, however, have shown that prophylaxis therapy can allow a hemophilic child to take part in vigorous activities or high-impact sports. The benefits of sports activity in children with hemophilia are expressed by a better muscular trophism and an improved bone mineral density. Moreover, physical activity has a positive impact on children's psychosocial well-being. Due to prophylaxis therapy, the quality of life of children with hemophilia is similar to their peers, and this has allowed an improvement in sports participation, including team sports.
