Background: physical exercise plays a role in the maintenance of the skeleton, but the specific mechanisms by which exercise increases bone mass are not understood. Purpose: The purpose of this study was to investigate the effect of continuous versus intermittent aerobic exercise on serum parathyroid hormone (PTH), ionized calcium (Ca2+) and bone alkaline phosphatase (B-ALP). Subjects: Thirty postmenopausal women aged between 5060 years were randomly assigned into two groups: Continuous exercise group (A) (n=15), and intermittent exercise group (B) (n=15). Materials and Methods: Continuous exercise consisted of walking exercise on treadmill for 40 minutes with moderate exercise intensity at 60%-70% of maximal heart rate. Intermittent exercise comprised walking exercise on treadmill for 20 minutes then 40 minutes of rest period followed by 20 minutes walking exercise with moderate exercise intensity 60%-70% of maximal heart rate for each period. Venous blood samples were collected immediately before and after the exercise session in both groups. Post ExercisesResults: The PTH was significantly higher in both groups (P<0.001), but it was significantly higher (p<0.05) in continuous exercise group compared to intermittent exercise group. TheCa2+decreased significantly in both groups (P<0.001), while it wassignificantly decreased (p<0.05) in continuous exercise group compared to intermittent exercise group. The B-ALP was increased significantly in both groups (P<0.001), but it was significantly higher in intermittent exercise group compared to continuous exercise group
