Many investigations have found that prolonged amenorrhea in female athletes is associated with a reduction in bone mineral density (BMD). As exercise is an osteogenic stimulus in itself, it is possible that some bone los...

Deficits in dynamic neuromuscular control of the knee may contribute to the higher incidence of anterior cruciate ligament (ACL) injury in female athletes. There is evidence that neuromuscular training alters muscle firing patterns, as it decreases landing forces, improves balance, and reduces ACL injury incidence in female athletes. The purpose of this review is to summarise the evidence for a...
