Vitamin D is synthesised in the skin during exposure to sunlight and its fundamental roles are the regulation of calcium and phosphate metabolism and bone mineralisation. The aim of our study was to evaluate serum levels of 25-hydroxyvitamin D3, PTH and bone turnover markers (P1NP, OC, beta-CTx, OC/beta-CTx) and the intake of calcium and vitamin D in Polish Professional Football League (Ekstraklasa) players and in young men with a low level of physical activity. Fifty healthy men aged 19 to 34 years were included in the study. We showed that 25(OH)D3 and P1NP levels and OC/beta-CTx were higher in the group of professional football players than in the group of physically inactive men. The daily vitamin D and calcium intake in the group of professional football players was also higher. We showed a significant relationship between 25(OH)D3 levels and body mass, body cell mass, total body water, fat-free mass, muscle mass, vitamin D and calcium intake. Optimum 25(OH)D3 levels were observed in a mere 16.7% of the football players and vitamin D deficiency was observed in the physically inactive men. The level of physical activity, body composition, calcium and vitamin D intake and the duration of exposure to sunlight may significantly affect serum levels of 25(OH)D3.
维生素D在皮肤暴露于阳光期间合成，其基本作用是调节钙和磷的代谢以及骨矿化。我们研究的目的是评估波兰职业足球联赛（甲级联赛）球员和身体活动水平较低的年轻男性的血清25-羟基维生素D3、甲状旁腺激素（PTH）和骨转换标志物（I型前胶原氨基端前肽（P1NP）、骨钙素（OC）、β-胶原降解产物（β-CTx）、OC/β-CTx）水平，以及钙和维生素D的摄入量。50名年龄在19至34岁的健康男性被纳入研究。我们发现，职业足球运动员组的25（OH）D3和P1NP水平以及OC/β-CTx高于身体不活跃男性组。职业足球运动员组的每日维生素D和钙摄入量也更高。我们发现25（OH）D3水平与体重、身体细胞质量、总体水、去脂体重、肌肉质量、维生素D和钙摄入量之间存在显著关系。仅16.7%的足球运动员观察到最佳25（OH）D3水平，而身体不活跃的男性中观察到维生素D缺乏。身体活动水平、身体成分、钙和维生素D摄入量以及阳光暴露时间可能会显著影响血清25（OH）D3水平。
