摘要

目的探讨男性青少年足球运动员落跳垂直运动动力学与急性非接触性膝关节损伤风险之间的关系。前瞻性队列研究。设立专业足球学院。青少年足球运动员（n = 264）。主要观察指标：落跳垂直动力学；伤害流行病学。使用二元逻辑回归评估动力学和损伤之间的关联。采用统计参数映射法比较受伤组与未受伤组的差异。结果制动：峰值推进力比(OR = 1.59, 1.10-2.29, p <；0.05),推进工作(OR = 0.53, 0.28 - -0.99, p & lt;0.05)和垂直刚度(OR = 1.68, 1.13-2.52, p <；0.05)与持续膝盖损伤的风险相关。所有变量都显示出“不可用”或“弱”水平的预测能力，以确定哪些球员会受伤（AUC 0.568-0.663）。结论：表征力-时间波形形状的落跳垂直动力学为男性青少年足球运动员急性非接触性膝关节损伤风险提供了见解。在地面接触的早期阶段，力量的大瞬时峰值，加上推进力的减少，是男性青少年足球运动员急性非接触性膝盖损伤的危险因素。变量不够敏感，不足以预测伤害，但提供了额外的训练目标，以帮助减轻这一人群的风险。

Drop jump vertical kinetics identify male youth soccer players at greater risk of non-contact knee injury

Objectives

To determine associations between drop-jump vertical kinetics and acute non-contact knee injury-risk in male youth soccer players.

Design

Prospective cohort study.

Setting

Professional soccer academies.

Participants

Youth soccer players (n = 264).

Main outcome measures

Drop-jump vertical kinetics; injury epidemiology. Associations between kinetics and injury were assessed using binary logistic regression. Differences between injured and uninjured groups were compared using statistical parametric mapping.

Results

Peak braking: peak propulsive force ratio (OR = 1.59, 1.10–2.29, p < 0.05), propulsive work (OR = 0.53, 0.28–0.99, p < 0.05) and vertical stiffness (OR = 1.68, 1.13–2.52, p < 0.05) were associated with risk of sustaining a knee injury. All variables demonstrated ‘unusable’ or ‘weak’ levels of predictive ability in identifying players who would become injured (AUC 0.568–0.663).

Conclusions

Drop-jump vertical kinetics that characterise the shape of the force-time waveform provide insight to acute non-contact knee injury-risk in male youth soccer players. Large transient spikes in force in the early phase of ground contact, coupled with reduced propulsive forces are a risk factor for acute non-contact knee injury in male youth soccer players. Variables are not sensitive enough to predict injury but provide additional training targets to help mitigate risk in this population.

期刊介绍： Physical Therapy in Sport is an international peer-reviewed journal that provides a forum for the publication of research and clinical practice material relevant to the healthcare professions involved in sports and exercise medicine, and rehabilitation. The journal publishes material that is indispensable for day-to-day practice and continuing professional development. Physical Therapy in Sport covers topics dealing with the diagnosis, treatment, and prevention of injuries, as well as more general areas of sports and exercise medicine and related sports science. The journal publishes original research, case studies, reviews, masterclasses, papers on clinical approaches, and book reviews, as well as occasional reports from conferences. Papers are double-blind peer-reviewed by our international advisory board and other international experts, and submissions from a broad range of disciplines are actively encouraged.
