Injuries in volleyball players are most common in the ankles and knees. Many volleyball players suffer from overuse injuries because of the strain placed on the lower extremities from repeated jumping. A characteristic of players who are most at risk for lower extremity injuries is the tendency to display trunk instability during landing, such as lateral flexion and rotation. Research has shown the effectiveness of exercise-based warm-up interventions for acute volleyball injuries. However, comprehensive analyses on the use of lower extremity, trunk, and balance programs to prevent overuse injuries are lacking.
To examine the effects of trunk and balance warm-up exercises on the prevention, severity, and length of limitation of overuse and acute lower limb injuries in male volleyball players.
Prospective, single-cohort study.
This study involved the 2019 (control group) and 2021 (intervention group) male volleyball teams. The control and intervention groups were on the same team; however, seven players joined in 2021 through a sports referral program through which different players are recruited. Measurements included injury incidence rate, injury severity, and injury burden. The intervention involved the addition of trunk and balance exercises during the 2021 season.
There was no significant difference in injury incidence rates between groups. Injury severity decreased by 3.7 days for overuse injuries (p=0.04). Injury burden decreased by 11.8 (days/1000 player hours) overall and by 7.1 (days/1000 player hours) for overuse injuries.
The results show that an exercise-based warm-up aimed at improving trunk posture during landing did not reduce the incidence rate of injury in men's volleyball. However, the addition of this warm-up did significantly reduce the severity of overuse injury.
Level 3B.
排球运动员的损伤最常见于脚踝和膝盖。许多排球运动员因反复跳跃给下肢带来的压力而遭受过度使用损伤。下肢受伤风险最高的运动员的一个特征是在落地时表现出躯干不稳定的倾向，如侧屈和旋转。研究表明基于运动的热身干预对急性排球损伤有效。然而，缺乏对使用下肢、躯干和平衡训练计划预防过度使用损伤的综合分析。
研究躯干和平衡热身运动对男性排球运动员过度使用和急性下肢损伤的预防、严重程度及受限时间的影响。
前瞻性单队列研究。
本研究涉及2019年（对照组）和2021年（干预组）男子排球队。对照组和干预组属于同一支球队；然而，2021年有7名球员通过体育推荐计划加入，该计划招募不同的球员。测量指标包括损伤发生率、损伤严重程度和损伤负担。干预措施是在2021赛季增加躯干和平衡训练。
两组之间的损伤发生率没有显著差异。过度使用损伤的严重程度降低了3.7天（p = 0.04）。总体损伤负担降低了11.8（天/1000球员小时），过度使用损伤的损伤负担降低了7.1（天/1000球员小时）。
结果表明，旨在改善落地时躯干姿势的基于运动的热身并未降低男子排球的损伤发生率。然而，增加这种热身确实显著降低了过度使用损伤的严重程度。
