Study on The Effect of Vitamin D and Nutrition Intervention on Improving Athletes Muscle Strength and Bone Strength
Osteoporosis is a skeletal disease that increases the risk of fractures due to decreased bone strength, along with decreased muscle strength, increased risk of falls, and fractures. Peak bones of athletes are lower than men's. After training, athletes' estrogen levels decrease and bone loss accelerates. Therefore, the prevalence of OP of athletes after training is increased compared with the general population. Studies have shown that vitamin D deficiency is associated with decreased muscle strength. After training, athletes can lose muscle mass and muscle strength with increasing age. The decline in physical activity caused by abnormal muscle quantity and quality is an independent risk factor for osteoporotic fractures caused by falls. At present, foreign conclusions on whether VitD supplementation can improve muscle strength and fracture occurrence have not been unified; related domestic research is limited, and there is no community-based prospective intervention study. This article observes the effects of intensive exercise, different vitamin D preparations, and calcium supplementation on muscle strength and fractures in high-risk groups of osteoporosis after training. Conclusion: Strengthening exercise and supplementing calcium may be beneficial to maintain and improve athletes 'muscle strength after training. Supplementing calcium and common vitamin D may improve athletes' muscle strength after training in a short time.
