Vitamin D deficiency is related to decreased muscle strength. Vitamin d obtained from food is absorbed with fat, and the absorption site is mainly in the jejunum and ileum. This article analyzes the effects of vitamin D and calcium supplementation on athletes’ muscle strength and fracture prevention. 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. Compared with the baseline level, the left-hand grip strength of group A was significantly lower than the baseline at 2-year follow-up, the right-hand grip strength of group B was significantly reduced at 1 year, and the left-hand grip strength of group C was significantly increased at 1-year. There was no hand-grip strength at 2 years of follow-up statistical changes. Intensive exercise and calcium supplementation may help maintain and improve athletes’ muscle strength after training. Calcium supplementation and general vitamin D may improve athletes' muscle strength after training in the short term.
