The use of compression garments has spread rapidly among athletes, largely because of marketing and perceived benefits. Upon review, it is unclear whether compression garments have a significant effect on performance and recovery, although they have been found to enhance proprioception. Further, it is reported that compression of the knee joint improves both dynamic and static balance. However, there is currently a paucity of data demonstrating the effects of compression garments on the biomechanical risk factors of knee-related injuries in female athletes.
To evaluate the ability of a directional compression garment to alter hip and knee kinematics and kinetics during a drop vertical jump (DVJ) in healthy college-aged female athletes.
Controlled laboratory study.
A sample of 23 healthy female collegiate athletes (mean age, 19.6 ± 1.3 years) participating in jumping sports (volleyball, basketball, and soccer) was included in this analysis. Each athlete performed 2 sets of 3 DVJs with and without a directional compression garment. Three-dimensional hip and knee kinematics and kinetics were collected using a standard Helen-Hayes 29-marker set, which was removed and reapplied after the garment was fitted, as well as 8 visible-red cameras and 2 force platforms. Each participant was tested in a single session.
Hip abduction range of motion was significantly reduced from 12.6° ± 5.5° to 10.2° ± 4.6° ( = .002) while performing DVJs without and with the compression garment, respectively. No statistically significant differences between conditions were found in peak hip abduction, knee valgus range of motion, peak valgus, peak hip abduction moment, and peak knee valgus moment.
The results of this study show that wearing compression garments does have minimal effects on lower body mechanics during landing from a DVJ, partially supporting the idea that compression garments could acutely alter movement patterns associated with the knee injury risk. However, further research should focus on muscle activation patterns and adaptations over time.
The use of specifically designed compression garments could aid in the prevention of knee injuries by inducing changes in jumping mechanics.
压缩衣在运动员中迅速普及,这主要归因于市场营销以及人们所感知到的益处。经审查发现,尽管压缩衣已被证实可增强本体感觉,但目前尚不清楚其对运动表现和恢复是否具有显著影响。此外,据报道,对膝关节进行加压可改善动态和静态平衡。然而,目前缺乏数据证明压缩衣对女运动员膝关节相关损伤的生物力学风险因素的影响。
评估定向压缩衣对健康的大学适龄女运动员进行下落式垂直跳(DVJ)时髋部和膝部运动学及动力学的改变能力。
对照实验室研究。
本分析纳入了23名参与跳跃运动(排球、篮球和足球)的健康女大学生运动员样本(平均年龄,19.6±1.3岁)。每位运动员在穿着和不穿着定向压缩衣的情况下各进行2组,每组3次下落式垂直跳。使用标准的海伦 - 海斯29标记集收集三维髋部和膝部运动学及动力学数据,在穿上压缩衣后移除并重新应用该标记集,同时使用8台可见红光摄像机和2个测力平台。每位参与者在单个时间段内接受测试。
在进行下落式垂直跳时,不穿和穿着压缩衣时,髋部外展活动范围分别从12.6°±5.5°显著减小至10.2°±4.6°(P = 0.002)。在髋部外展峰值、膝内翻活动范围、峰值内翻、髋部外展峰值力矩和膝内翻峰值力矩方面,不同条件之间未发现统计学上的显著差异。
本研究结果表明,穿着压缩衣在下落式垂直跳着陆时对下肢力学确实具有最小影响,部分支持了压缩衣可急性改变与膝关节损伤风险相关的运动模式这一观点。然而,进一步的研究应关注肌肉激活模式以及随时间的适应性变化。
使用专门设计的压缩衣可通过诱导跳跃力学的变化来帮助预防膝关节损伤。
