The effect of autumn, winter and spring changes on the vitamin D level of female athletes

Vitamin D plays an important role in supporting bone health and immune function. According the results of the studies, vitamin D deficiency is very prevalent among common people and athletes in different countries. Moreover, vitamin D deficiency is the cause of bone and other disorders. the results of the study show that the level of serum ۲۵(OH)D is depends on seasonal variation. The study population included ۶۳ female athletes (۲۳to۴۷years old), who were participated voluntarily, in the middle of autumn, winter and spring. Serum ۲۵-hydroxy-vitamin D (۲۵(OH)D) levels were measured by DS۲DYnex, that is made in America, with method of Aliza. The value of ۲۵(OH)D< was considered as deficiency, > as insufficiency, ≤۲۵(OH)D>۳۰ as sufficient levels. the levels of deficiency and insufficiency were ۶۶.۷% and ۳۳.۳% in autumn, ۴.۸% and ۹۵.۲% in winter, ۲۰.۶% and ۷۶.۲% in spring respectively.۳.۲%of people had adequate levels of vitamin D in spring. there was a significant difference between the serum ۲۵(OH)D in autumn and winter, winter and spring. There was no significant difference between the serum ۲۵(OH)D in autumn and spring. the highest level of vitamin D mean was in autumn and the lowest level was in winter. These findings indicate the necessity for research projects and actions to prevent vitamin D deficiency.Vitamin D plays an important role in supporting bone health and immune function.
