在生长发育期增加骨量的沉积和减少老年期骨量的丢失是预防骨质疏松的主要策略。儿童青少年期,尤其是青春前期,参加承重运动能促进腰椎和股骨颈的骨量增长,这种优势在运动终止后仍保持较长时间。但体力活动对儿童青少年骨量的具体影响与研究对象的年龄、研究部位、运动类型以及运动持续时间有关。在老年人中开展的研究表明,一定强度的体力活动可能会减少老年人骨量丢失,降低跌倒发生的危险性,但在体力活动终止后对骨量的益处消失。
In the growth and development to increase the deposition of bone mass and reduce the loss of bone mass in old age is the main strategy to prevent osteoporosis. Childhood adolescence, especially in early adolescence, to participate in weight-bearing sports can promote bone and lumbar spine bone growth, this advantage remained for a long time after the termination of the campaign. However, the specific impact of physical activity on bone mass in children and adolescents is related to the age, study site, type of exercise and duration of exercise. Studies in the elderly have shown that a certain intensity of physical activity may reduce bone loss in the elderly and reduce the risk of falls, but the benefits of bone mass disappear after physical activity is terminated.
