Effects of Jumping Exercise and Nutritional Management on Bone Mineral Density and Bone Turnover Markers in a Young Man

Jun Iwamoto

The strategy for increasing bone mineral density (BMD) has not been established in young men with low BMD. We report on a case of a young man with low BMD who was treated with exercise and nutritional management. A 29-year of old man consulted our clinic because of low BMD. He was instructed to perform maximum jumping exercise (5 times per day, 5 days per week) and intake calcium (800 mg/day), vitamin D (800 IU or 20 μg/day), and vitamin K (300 μg/day) for 6 months. The lumbar spine and femoral neck BMD increased by 2.9% and 4.7%, respectively. These results suggest the effectiveness of maximum jumping exercise and nutritional management (calcium, vitamin D, and vitamin K) on the BMD of the clinically relevant skeletal sites in young men with low BMD.
