The effect of resistance training on the frequency of bleeding in haemophilia patients: a pilot study.

The benefits and feasibility of progressive resistance training on muscle strength and bleeding profile were studied prospectively in two patients with severe haemophilia. Additionally, retrospective data were collected from three patients who had been training for 11-21 years (one patient for 21 years and two patients for 11 years). Muscle strength increased, especially in muscle groups surrounding the target joints (elbow and knee). Bleeding frequency decreased from 2-3 times per week to 1-2 times per week. Patients who had been training for > 11 years reported bleeding episodes of 2-4 times per month prior to training, but after > 11 years of progressive training a marked decrease in bleeding occurred, as well as a decrease in severity. These data support the importance of resistance training for haemophilia patients, not only for increasing muscle strength, but also for decreasing the frequency and severity of bleeding episodes and the associated pain. A controlled study, with a greater number of patients, is needed to confirm the suggested benefits of resistance training in haemophilia patients.
