背景：维生素D是一种脂溶激素，在骨骼健康、肌肉功能和运动表现中发挥作用。研究表明，低水平的维生素D会导致肌肉恢复和功能减慢，应力性骨折的发生率增加，甚至运动表现更差。职业篮球和足球运动员维生素D水平不足已被证实，然而，到目前为止，还没有关于职业曲棍球运动员维生素D缺乏的研究。目的/假设：这项研究的目的是进行一项横断面回顾，以确定职业曲棍球运动员维生素D缺乏和不足的患病率。研究设计：横断面研究，证据水平3。方法：对105名职业曲棍球运动员季前赛血清25-羟基维生素D实验室检测结果进行回顾分析。所有来自国家曲棍球联盟(NHL)3支球队的球员都包括在内。评估的球员参数包括年龄、身高、体重、体重指数和25(OH)维生素D水平。运动员根据血清维生素D水平分为4组：缺乏组(=32 ng/m L)和理想组(=40 ng/m L)。结果：105名运动员的25(OH)维生素D平均水平为45.8+/-13.7 ng/mL(范围24-108 ng/mL)。这项研究中没有一名参与者被认为有缺陷。共有14名球员(13.3%)被认为不足，91名球员(86.7%)被认为足够。然而，只有68名球员(64.8%)被认为是理想的。在进行比较时，维生素D水平充足的运动员比维生素D水平不足的运动员年龄大(25.9岁比23.1岁；P=.018)。结论：尽管职业曲棍球运动员参加冬季运动，并花费大量时间在室内训练，但他们的维生素D缺乏水平较低。
Background: Vitamin D is a fat-soluble hormone that plays a role in bone health, muscle function, and athletic performance. Studies have shown that low levels of vitamin D can lead to slower muscle recovery and function, increased rates of stress fractures, and even poorer athletic performance. Insufficient vitamin D levels have been demonstrated in professional basketball and football players, however, there have been no studies to date reviewing vitamin D insufficiency in professional hockey players.Purpose/Hypothesis: The purpose of this study was to perform a cross-sectional review to determine the prevalence of vitamin D deficiency and insufficiency in professional hockey players. The hypothesis was that there would be a high percentage of players with vitamin D insufficiency.Study Design: Cross-sectional study; Level of evidence, 3.Methods: The preseason serum 25-hydroxy (OH) vitamin D laboratory test results of 105 professional hockey players were retrospectively reviewed. All players on 3 National Hockey League (NHL) teams were included. Player parameters evaluated included age, height, weight, body mass index, and 25(OH) vitamin D level. Players were divided into 4 groups based on serum vitamin D levels: deficient (= 32 ng/mL), and ideal (>= 40 ng/mL). Descriptive statistics were performed, in addition to 2-group and 3-group comparisons.Results: The average 25(OH) vitamin D level of 105 players was 45.8 +/- 13.7 ng/mL (range, 24-108 ng/mL). No players in the study were considered deficient. A total of 14 players (13.3%) were considered insufficient, while 91 players (86.7%) were considered sufficient. However, only 68 players (64.8%) were considered ideal. When comparing groups, athletes with sufficient vitamin D levels were older than athletes with insufficient vitamin D levels (25.9 vs 23.1 years; P = .018). All other player parameters demonstrated no significant difference between groups.Conclusion: Despite playing a winter sport and spending a great deal of time training indoors, professional hockey players have low levels of vitamin D insufficiency.
