Abstract:

BACKGROUND: Bone metabolism has become an important topic in recent years. Suitable exercise training has a positive effect on bone metabolism, and different exercise methods have different effects on bone metabolism. However, there is a lack of comprehensive and systematic understanding of the effects of sports on bone metabolism related mechanisms.
OBJECTIVE: To review the effects of exercise on bone metabolism reported by scholars inside and outside China and reveal the biochemical and biomechanical mechanisms of bone metabolism and the positive effects of exercise on bone metabolism, providing theoretical basis and practical reference for increasing the efficacy of bone metabolism and preventing metabolic diseases such as osteoporosis.
METHODS: A computer-based online search of Elsevier, Springer, CNKI, Wanfang database, VIP and Taiwan Academic Literature Database was performed to retrieve literatures regarding bone metabolism and exercise training in Chinese and English. These retrieved literatures were screened against inclusion and exclusion criteria.
RESULTS AND CONCLUSION: The mechanism of bone remodeling is an important process of bone metabolism. The influence of exercise on the biomechanical mechanism of bone metabolism mainly has two aspects. One is to directly stimulate the direction of force acting on the bone. The other is the indirect stimulation of muscle contraction during exercise to bone, which manifests as the effects of exercise on peak bone mass, the reduction of bone loss, and bone mineral density in a specific area during the growth period. Exercise can increase peak bone mass and reduce bone loss during the growth period. Different types of exercise have different effects on bone metabolism.

Key words: bone metabolism, bone remodeling, muscle contraction, bone density, exercise training, aerobic training, resistance training, impact training
