Regular exercise or high physical activity levels are associated with higher serum 25-hydroxyvitamin D [25(OH)D] concentrations; however, the effect of acute exercise on serum 25(OH)D concentrations remains unclear.
We aimed to clarify whether acute endurance exercise has a direct effect on the circulating 25(OH)D concentrations in young adults.
Exercise intervention trial in an institutional practice.
Twenty young, active adults (males, n = 10; females, n = 10).
Participants were asked to perform a cycling exercise for 30 minutes at 70% maximal oxygen uptake.
The serum concentrations of 25(OH)D and other blood parameters were assessed before exercise and at 0, 0.5, 1, 3, and 24 hours after exercise.
The serum 25(OH)D concentrations were significantly increased not only at 0 (P < 0.01), 1 (P < 0.05), and 3 hours (P < 0.01) after exercise, but they were also increased at 24 hours (P < 0.05) after acute endurance exercise in young adults. A significant sex × time interaction effect was observed (P < 0.05), and the incremental areas under the curve for the 25(OH)D concentrations were significantly higher in men than in the women (P < 0.01).
There is a direct effect of endurance exercise on serum 25(OH)D concentrations. In addition, sex disparity was observed in the serum 25(OH)D response to acute endurance exercise, and the increase in 25(OH)D concentrations was greater in men than in women.
规律运动或较高的身体活动水平与较高的血清25-羟维生素D[25(OH)D]浓度相关；然而，急性运动对血清25(OH)D浓度的影响仍不清楚。
我们旨在阐明急性耐力运动是否对年轻成年人循环中的25(OH)D浓度有直接影响。
在机构实践中的运动干预试验。
20名年轻、活跃的成年人（男性，n = 10；女性，n = 10）。
参与者被要求以最大摄氧量的70%进行30分钟的骑自行车运动。
在运动前以及运动后0、0.5、1、3和24小时评估血清25(OH)D浓度和其他血液参数。
年轻成年人急性耐力运动后，血清25(OH)D浓度不仅在运动后0小时（P < 0.01）、1小时（P < 0.05）和3小时（P < 0.01）显著升高，而且在24小时（P < 0.05）也升高。观察到显著的性别×时间交互效应（P < 0.05），男性25(OH)D浓度曲线下增量面积显著高于女性（P < 0.01）。
耐力运动对血清25(OH)D浓度有直接影响。此外，在血清25(OH)D对急性耐力运动的反应中观察到性别差异，男性25(OH)D浓度的升高大于女性。
