Summary Sport is nowadays perceived as beneficial for children with haemophilia, as good muscle strength supports joints and may reduce bleed frequency; by contrast psychological benefits are less known. This study introduces the impact of sport on health‐related quality of life (HRQoL) and physical performance in children with haemophilia. A cross‐sectional, multi‐site, study of boys aged 6–17 years with haemophilia A or B of any severity, current or past inhibitor, which assessed physical performance, sporting activity and HRQoL using age appropriate questionnaires including KINDL, Haemo‐QoL and HEP‐Test‐Q. Eighty‐four haemophilic boys (23 mild, 19 moderate, 42 severe) with a mean age of 11.52 years (SD = 3.4) were enrolled from two haemophilia centres in the United Kingdom. 28.4% were overweight/obese according to their BMI/age and had a good orthopaedic status (M = 1.55, SD = 3.3).
