Lower physical activity and altered body composition in patients with haemophilia compared with healthy controls.

Although physical activity has been recommended for PWH since the mid-1970s, the physical activity engagement of adult PWH was still severely limited, possibly due to over-cautiousness but presumably also in consequence of chronic pain. Poor physical activity engagement may well be expected to contribute to the increased body fat and decreased leg muscle mass. Consequently, policies should focus on improving the knowledge and motivation of PWH to engage in health-enhancing physical activity.
