Male athletes may need calcium supplementation to keep their bones strong

Researchers at the University of Memphis measured the calcium levels of basketball players and found that after intense exercise the players lost an average of 422 milligrams of calcium in sweat during each session compared with a loss of 40 to 144 milligrams per day during mild activity.

Researchers also found that over 10 months the players total body bone mineral content declined by 6 per cent and the bone mineral content in their legs declined by 10.5 per cent. When the players received 2 grams of oral calcium supplements the next season their lean body mass increased and average bone mineral content increased by 5 per cent.
