Adductor strains are the most common non-contact musculoskeletal injury sustained in ice hockey. Systematic reviews have determined higher level of play and lower hip adduction to abduction strength ratios to be associated with an increased risk of adductor strain across multiple sports. Limited research exists regarding hip adduction and abduction strength profiles across various levels of ice hockey players.
To compare isometric hip adduction and abduction strength profiles among bantam, high school, tier one juniors, and NCAA Division I collegiate ice hockey players. A secondary purpose was to identify whether differences in strength profiles between dominant and non-dominant limbs exist.
Cross-sectional cohort study.
A questionnaire of demographic data, hockey, and injury specific information was completed by all subjects. The mean of three reps of maximal hip isometric adduction and abduction strengths were quantified using a handheld dynamometer with external belt-fixation. Ratios of hip adduction-to-abduction strength were calculated and normalized for body weight.
A total of 87 uninjured skaters were included in this study with a mean age of 17 years. Mean hip adductor-to-abductor ratios for Bantam hockey players were 121% followed by collegiate (115%), Juniors (111%), and high school (109%) hockey players. No statistically significant differences were found between peak hip adduction and abduction isometric strength and playing level. In addition, there was no difference between unilateral hip strength ratios and shooting hand or leg dominance. While 34.5% of subjects reported a history of adductor injury, no significant differences existed regarding strength ratios during bilateral comparison or when compared to their team norms. Three subjects were found to have unilateral ratios of less than 80%, while two subjects demonstrated bilateral ratios of less than 80%.
Symmetry is illustrated between dominant and non-dominant legs in ice hockey players with and without a history of adductor injury. Results align well with previously established cross-sectional data from Australian football, with ratios of 103% in high school players, 107% in semi-professional players, and 113% in collegiate players.

内收肌拉伤是冰球运动中最常见的非接触性肌肉骨骼损伤。系统评价已确定，在多项运动中，高水平比赛以及较低的髋内收与外展力量比值与内收肌拉伤风险增加有关。关于不同水平冰球运动员的髋内收和外展力量特征的研究有限。
比较少年冰球运动员、高中冰球运动员、一级青年冰球运动员和美国大学体育协会（NCAA）一级大学冰球运动员的等长髋内收和外展力量特征。第二个目的是确定优势肢体和非优势肢体之间的力量特征是否存在差异。
横断面队列研究。
所有受试者均完成了一份关于人口统计学数据、冰球和损伤特定信息的问卷。使用带有外部腰带固定的手持测力计对最大髋等长内收和外展力量的三次重复测量的平均值进行量化。计算髋内收与外展力量的比值，并按体重进行标准化。
本研究共纳入87名未受伤的滑冰运动员，平均年龄为17岁。少年冰球运动员的平均髋内收与外展比值为121%，其次是大学冰球运动员（115%）、青年冰球运动员（111%）和高中冰球运动员（109%）。髋内收和外展等长力量峰值与比赛水平之间未发现统计学上的显著差异。此外，单侧髋部力量比值与射门手或腿部优势之间也没有差异。虽然34.5%的受试者报告有内收肌损伤史，但在双侧比较或与团队标准比较时，力量比值没有显著差异。发现三名受试者的单侧比值低于80%，而两名受试者的双侧比值低于80%。
有或无内收肌损伤史的冰球运动员的优势腿和非优势腿之间表现出对称性。研究结果与之前澳大利亚足球的横断面数据非常吻合，高中球员的比值为103%，半职业球员为107%，大学球员为113%。
