Episodes of bleeding in people with haemophilia (PWH) are associated with reduced activity and limitations in physical performance. Within the scope of the 'Haemophilia & Exercise Project' (HEP) PWH were trained in a sports therapy programme. Aim of this study was to investigate subjective and objective physical performance in HEP-participants after 1 year training. Physical performance of 48 adult PWH was compared before and after sports therapy subjectively (HEP-Test-Q) and objectively regarding mobility (range of motion), strength and coordination (one-leg-stand) and endurance (12-min walk test). Sports therapy included an independent home training that had previously been trained in several collective sports camps. Forty-three controls without haemophilia and without training were compared to PWH. Of 48 PWH, 13 performed a regular training (active PWH); 12 HEP-participants were constantly passive (passive PWH). Twenty-three PWH and 24 controls dropped out because of incomplete data. The activity level increased by 100% in active PWH and remained constant in passive PWH, and in controls (P ? 0.05). Only mobility of the right knee was significantly improved in active PWH (+5.8 ± 5.3°) compared to passive PWH (-1.3 ± 8.6°). The 12-min walk test proved a longer walking distance for active PWH (+217 ± 199 m) compared to controls (-32 ± 217 m). Active PWH reported a better subjective physical performance in the HEP-Test-Q domains 'strength & coordination', 'endurance' and in the total score (+9.4 ± 13.8) compared to passive PWH (-5.3 ± 13.5) and controls (+3.7 ± 7.5). The 'mobility'-scale and one-leg-stand remained unchanged. Sports therapy increases the activity level and physical performance of PWH, whereby objective effects do not always correspond with subjective assessments.
