摘要

背景：在羽毛球运动中，下肢损伤经常发生在意想不到的扣球落地动作中。此外，下肢受伤的风险可能因不同的着陆策略而异。本研究旨在探讨意外因素和两种反手区域扣球动作对下肢生物力学的影响。方法：采用运动捕捉系统和测力板采集13名女运动员(年龄：21.2±1.9岁；高度：167.1±4.1 cm；体重：57.3±5.1 kg)，在预期和非预期条件下反手后场跳扣球（BRJS）和反手侧跳扣球（BLJS）。出人意料的任务是让运动员随机进行一些特定的羽毛球角球练习，然后由指示牌发出随机的运动命令，然后由机器将毽子扔向左半场。波形分析采用统计参数映射，离散参数分析采用2 × 2重复测量方差分析。结果：在非预期条件下，BRJS和BLJS均能提高初始接触（IC）时的垂直瞬时载荷率（p = 0.003, η p 2 = 0.314）和膝关节伸直力矩（p = 0.013, η p 2 = 0.231）。主效应结果表明，与BLJS相比，BRJS在IC状态下产生了更大的膝关节外展角（p = 0.03, η p 2 = 0.182）和膝关节内收力矩（p = 0.010, η p 2 = 0.248），而交互效应表明BRJS在非预期状态下具有更大的锋面压力位移中心（p = 0.041, η p 2 = 0.186）。与BRJS相比，BLJS具有更大的膝关节伸展力矩（p = 0.013, η p 2 = 0.231）和更小的膝关节屈曲角（p = 0.002, η p 2 = 0.347）和髋关节屈曲角（p < 0.001, η p 2 = 0.491）。此外，与BRJS相比，BLJS表现出更高的踝关节内旋转峰值力矩（p = 0.018, η p 2 = 0.212），并且在非预期条件下踝关节翻转峰值力矩更大。结论：意想不到的因素显著影响了两种扣球落地动作的生物力学，潜在地增加了前交叉韧带损伤的风险。此外，在BLJS运动过程中，意想不到的因素可能会增加踝关节扭伤的风险。

Impact of unanticipated and backhand area smash landing on the lower limb biomechanics of female badminton players.

Background: In badminton, lower limb injuries frequently occur during unanticipated smash landing movements. Additionally, the risk of lower limb injuries may vary depending on different landing strategies. This study aims to investigate the impact of unanticipated factors and two types of smash actions in the backhand area on lower limb biomechanics.

Method: A motion capture system and force plates were used to collect biomechanic data of 13 female athletes (age: 21.2 ± 1.9 years; height: 167.1 ± 4.1 cm; weight: 57.3 ± 5.1 kg) during backhand rear-court jump smash (BRJS) and backhand lateral jump smash (BLJS) in both anticipated and unanticipated conditions. Unanticipated tasks were conducted by having the athletes perform a random number of specific badminton corner drills, followed by a random movement command given by a signboard and a shuttlecock being launched towards the left half-court by a machine. Waveform analysis was performed using Statistical Parametric Mapping, and discrete parameters were analyzed using a 2 × 2 repeated measures ANOVA.

Results: The results indicated that under unanticipated conditions, both BRJS and BLJS led to higher vertical instantaneous load rates (p = 0.003, $η_{p}^{2}$ = 0.314) and knee extension moments (p = 0.013, $η_{p}^{2}$ = 0.231) at initial contact (IC). The main effect results indicated that BRJS caused greater knee abduction angles (p = 0.03, $η_{p}^{2}$ = 0.182) and knee adduction moments (p = 0.010, $η_{p}^{2}$ = 0.248) at IC than BLJS, while the interaction effects showed that BRJS had a greater frontal plane center of pressure displacement under unanticipated conditions (p = 0.041, $η_{p}^{2}$ = 0.186). BLJS showed greater knee extension moments (p = 0.013, $η_{p}^{2}$ = 0.231) and smaller knee (p = 0.002, $η_{p}^{2}$ = 0.347) and hip (p < 0.001, $η_{p}^{2}$ = 0.491) flexion angles at IC compared to BRJS. Additionally, BLJS demonstrated higher peak ankle internal rotation moments (p = 0.018, $η_{p}^{2}$ = 0.212) than BRJS, with a greater peak ankle inversion moment under unanticipated conditions.

Conclusion: Unanticipated factors significantly impacted the biomechanics of both smash landing actions, potentially increasing the risk of ACL injuries. Moreover, unanticipated factors may increase the risk of ankle sprains during the BLJS movement.

期刊介绍： The translation of new discoveries in medicine to clinical routine has never been easy. During the second half of the last century, thanks to the progress in chemistry, biochemistry and pharmacology, we have seen the development and the application of a large number of drugs and devices aimed at the treatment of symptoms, blocking unwanted pathways and, in the case of infectious diseases, fighting the micro-organisms responsible. However, we are facing, today, a dramatic change in the therapeutic approach to pathologies and diseases. Indeed, the challenge of the present and the next decade is to fully restore the physiological status of the diseased organism and to completely regenerate tissue and organs when they are so seriously affected that treatments cannot be limited to the repression of symptoms or to the repair of damage. This is being made possible thanks to the major developments made in basic cell and molecular biology, including stem cell science, growth factor delivery, gene isolation and transfection, the advances in bioengineering and nanotechnology, including development of new biomaterials, biofabrication technologies and use of bioreactors, and the big improvements in diagnostic tools and imaging of cells, tissues and organs. In today`s world, an enhancement of communication between multidisciplinary experts, together with the promotion of joint projects and close collaborations among scientists, engineers, industry people, regulatory agencies and physicians are absolute requirements for the success of any attempt to develop and clinically apply a new biological therapy or an innovative device involving the collective use of biomaterials, cells and/or bioactive molecules. “Frontiers in Bioengineering and Biotechnology” aspires to be a forum for all people involved in the process by bridging the gap too often existing between a discovery in the basic sciences and its clinical application.
