Vitamin D status has been associated with cardiorespiratory fitness (CRF) in cross-sectional investigations in the general population. Data characterizing the association between 25-hydroxyvitamin D (25(OH)D) concentration and CRF in athletes are lacking. Junior and collegiate ice hockey players were recruited from the Minneapolis, MN (44.9° N), area during the off-season period (May 16-June 28). The purpose of this study was to examine the cross-sectional association between 25(OH)D concentration and CRF in a sample population of competitive ice hockey players. Circulating 25(OH)D level was assessed from a capillary blood sample analyzed using liquid chromatography-tandem mass spectrometry. V[Combining Dot Above]O2peak during a skate treadmill graded exercise test (GXT) was used to assess CRF. Data on both 25(OH)D concentration and V[Combining Dot Above]O2peak were available for 52 athletes. Insufficient 25(OH)D concentrations were found in 37.7% of the athletes (<32 ng·ml). Vitamin D status was not significantly associated with any physiological or physical parameter during the skate treadmill GXT.
在一般人群的横断面调查中，维生素D状态与心肺适能（CRF）有关。目前缺乏关于运动员中25-羟基维生素D（25(OH)D）浓度与CRF之间关联的数据。在休赛期（5月16日至6月28日），从明尼苏达州明尼阿波利斯市（北纬44.9°）招募了青少年和大学冰球运动员。本研究的目的是在一组竞技冰球运动员样本中，检验25(OH)D浓度与CRF之间的横断面关联。通过使用液相色谱-串联质谱法分析的毛细血管血样评估循环25(OH)D水平。在滑冰跑步机分级运动试验（GXT）期间的最大摄氧量（V̇O₂peak）用于评估CRF。52名运动员同时有25(OH)D浓度和V̇O₂peak的数据。37.7%的运动员25(OH)D浓度不足（<32 ng·ml）。在滑冰跑步机GXT期间，维生素D状态与任何生理或身体参数均无显著关联。
