Abstract

Background: Patients with hemophilia A have low bone density than healthy controls. It is now widely recognized that physical activity and sports are beneficial for patients with hemophilia. Objective: The aim of this study was to compare the effects of mild and moderate intensity treadmill walking exercises on markers of bone metabolism and hand grip strength in male patients with moderate hemophilia A. Material and Methods: Fifty male patients with moderate hemophilia, their age ranged from 25 to 45 years. The subjects were randomly assigned into 2 equal groups; the first group (A) received moderate intensity aerobic exercise training. The second group (B) received mild intensity aerobic exercise training. Results: There was a 32.1% and 24.8% increase in mean values of Serum Calcium and Hand grip strength respectively and 22.7 % reduction in mean values of parathyroid hormone in moderate exercise training group (A). While, There was a 15.1 % and 15 % increase in mean values of Serum Calcium and Hand grip strength respectively and 10.3 % reduction in mean values of parathyroid hormone in mild exercise training group(B). The mean values of Serum Calcium and Hand grip strength were significantly increased, while the mean values of parathyroid hormone were significantly decreased in both groups .Also, there were significant differences between mean levels of the investigated parameters in group (A) and group (B) after treatment. Conclusion: Moderate intensity aerobic exercise training on treadmill is appropriate to improve markers of bone metabolism and hand grip strength in male patients with hemophilia A.
