背景：较高水平的体力活动和心肺功能与血清25-羟基维生素D [25（OH）D]浓度呈正相关;然而，25（OH）D浓度对慢性耐力运动训练的反应尚不清楚。因此，本研究的目的是阐明血清25（OH）D浓度是否直接增加5周的耐力运动训练和影响体脂肪的变化在老年mention.Methods：20名日本老年男子被随机分为5周的耐力运动训练组（ET组; N = 10）或久坐不动的对照组（SC组; N = 10）。采集空腹血测定血清25（OH）D等血液指标。内脏脂肪面积和肝脏脂肪含量分别通过磁共振成像和质子磁共振spectroscopic.Results：5周耐力运动训练后，ET组的最大摄氧量（VO 2 max）水平从基线时的23.3显著增加至终点时的28.1 mL/kg/min; SC组的水平无变化。SC组血清25（OH）D浓度随季节变化有显著性降低（P < 0.05），而ET组无明显变化。结果可能部分归因于ET组肝内脂肪的轻微减少。没有观察到身体脂肪或内脏脂肪areas.Conclusions百分比的变化：我们的研究结果表明，5周的耐力训练可以抑制血清25（OH）D浓度的季节性下降，而不改变身体脂肪。
Background:Higher levels of physical activity and cardiorespiratory fitness are positively related to serum 25-hydroxyvitamin D [25(OH)D] concentrations; however, the response of 25(OH)D concentrations to chronic endurance exercise training is unclear. Therefore, the purpose of this study was to elucidate whether serum 25(OH)D concentrations were directly increased by 5 weeks of endurance exercise training and influenced by changes in body fat in elderly men.Methods:Twenty elderly Japanese men were randomized to either the 5-week endurance exercise training group (ET group; N = 10) or the sedentary control group (SC group; N = 10). Fasting blood samples were collected to determine serum 25(OH)D and other blood parameters. The visceral fat area and hepatic fat content were assessed by magnetic resonance imaging and proton magnetic resonance spectroscopy, respectively.Results:After 5 weeks of endurance exercise training, the levels of maximal oxygen uptake (VO2max) were significantly increased from 23.3 at baseline to 28.1 mL/kg/min at the endpoint for the ET group; levels were unchanged for the SC group. A significant seasonal reduction in serum 25(OH)D concentrations was observed in the SC group (P < 0.05), while no change was found in the ET group. The results may be partly attributed to the slight decrease in intrahepatic fat in the ET group. No changes were observed in percent body fat or visceral fat area.Conclusions:The results of our study suggest that 5 weeks of endurance training could inhibit the seasonal reduction in serum 25(OH)D concentrations without changes in body fat.
