背景：生物反馈训练使运动员能够通过接受生物力学和生理学数据来改变生物力学和生理学功能，目的：比较两种不同的实时生物反馈模式对减少前交叉韧带损伤相关危险因素的效果。高中女子足球运动员（年龄14.8 ± 1.0岁，身高162.6 ± 6.8 cm，体重55.9 ± 7.0 kg; n = 4）。干预：在重复双腿下蹲期间进行一组基于动力学或运动学的实时生物反馈。主要结果指标：收集基线和训练后的垂直跳，以确定是否有任何反馈方法改善了高损伤风险的着陆力学。在动力学聚焦生物反馈后，着陆过程中的最大膝关节外展力矩和角度显著降低（P = .04）。在运动学聚焦生物反馈后的垂直跳跃中，膝关节外展力矩的减少没有差异（P = .2）。最大膝关节外展角显着减少后，动力学生物反馈（P <0.01），但只有运动学生物反馈（P = 0.08）。结论：创新的生物反馈在本研究中采用减少膝关节外展负荷和姿势从基线到训练后在下降垂直跳。
CONTEXT: Biofeedback training enables an athlete to alter biomechanical and physiological function by receiving biomechanical and physiological data concurrent with or immediately after a task.OBJECTIVE: To compare the effects of 2 different modes of real-time biofeedback focused on reducing risk factors related to anterior cruciate ligament injury.DESIGN: Randomized crossover study design.SETTING: Biomechanics laboratory and sports medicine center.PARTICIPANTS: Female high school soccer players (age 14.8 ± 1.0 y, height 162.6 ± 6.8 cm, mass 55.9 ± 7.0 kg; n = 4).INTERVENTION: A battery of kinetic- or kinematic-based real-time biofeedback during repetitive double-leg squats.MAIN OUTCOME MEASURES: Baseline and posttraining drop vertical jumps were collected to determine if either feedback method improved high injury risk landing mechanics.RESULTS: Maximum knee abduction moment and angle during the landing was significantly decreased after kinetic-focused biofeedback (P = .04). The reduced knee abduction moment during the drop vertical jumps after kinematic-focused biofeedback was not different (P = .2). Maximum knee abduction angle was significantly decreased after kinetic biofeedback (P < .01) but only showed a trend toward reduction after kinematic biofeedback (P = .08).CONCLUSIONS: The innovative biofeedback employed in the current study reduced knee abduction load and posture from baseline to posttraining during a drop vertical jump.
