A limited number of studies on the epidemiology of injuries and fitness profiles of netball players in South Africa have been conducted, but no research on the potential morphological and skill-related fitness predictors of injuries could be located.
We investigated whether morphological or skill-related factors measured in the pre-season could predict injuries sustained in-season.
In our cohort study, 77 under-18 (U18), U19, U21 and senior elite netball players underwent pre-season testing including anthropometry, balance, flexibility, explosive power, upper and lower body strength, core strength, speed and agility testing. A questionnaire was used to collect demographic data, elite-level experience and injury history. Injuries in pre-season, training and matches were recorded during the subsequent 2017-2018 season using an injury profile sheet.
Amongst the 77 players who underwent pre-season fitness tests, 33 players (42.9%) had at least one injury. Regarding player morphology, a significant association of body mass and body fat percentage with injury risk was found in a simple logistic regression. In a multiple logistic regression analysis, only fat percentage ( = 0.0508) remained a significant predictor of injury at the 10% significance level, with higher fat percentage being associated with lower injury risk.
Heavier players and players with a higher fat percentage had a decreased injury risk.
As a result of the apparent protective effect of heavier weight of players, referees should more strictly enforce the no-contact rule in netball. Further research on functional movement screening as a tool for potential prediction of injury in netball is recommended.
南非针对无挡板篮球运动员的损伤流行病学及体能状况开展的研究数量有限，但尚未找到关于损伤潜在形态学和技能相关体能预测因素的研究。
我们调查了季前测量的形态学或技能相关因素是否能够预测赛季中发生的损伤。
在我们的队列研究中，77名18岁以下（U18）、U19、U21和成年精英无挡板篮球运动员接受了季前测试，包括人体测量、平衡、柔韧性、爆发力、上下肢力量、核心力量、速度和敏捷性测试。通过问卷调查收集人口统计学数据、精英水平经历和损伤史。在随后的2017 - 2018赛季，使用损伤情况记录表记录季前、训练和比赛中的损伤情况。
在接受季前体能测试的77名运动员中，33名运动员（42.9%）至少有一次损伤。关于运动员形态，在简单逻辑回归中发现体重和体脂百分比与损伤风险存在显著关联。在多元逻辑回归分析中，只有体脂百分比（ = 0.0508）在10%显著性水平下仍然是损伤的显著预测因素，较高的体脂百分比与较低的损伤风险相关。
体重较重和体脂百分比更高的运动员损伤风险降低。
由于运动员体重较重具有明显的保护作用，裁判员应在无挡板篮球比赛中更严格地执行无接触规则。建议进一步研究将功能动作筛查作为预测无挡板篮球损伤可能性的工具。
