Amongst women in exercise training, the female athlete triad is on the increase. This is the combination of disordered eating, amenorrhoea and osteoporosis. However, the effects of exercise training on bone mineral accumulation in youngsters is not fully known. Bone mass increases rapidly during childhood and adolescence until peak bone mass (PBM) is attained. PBM is an important determinant of adult bone mineral density (BMD) and therefore optimisation of PBM is valuable in the prevention of osteoporosis. This paper reviews the effects of exercise training on the accumulation of bone mineral in girls.
