Abstract

Anterior cruciate ligament (ACL) injury is common in sports that include 'change in direction' tasks. The aim of the current study was to determine the association between T2 relaxation time (an indicator of ACL integrity) of the distal portion of the ACL sub-region, biomechanical loading factors of the ACL, sex, and sport status of the participants. Participants between 18 to 35 years performed unanticipated 'change in direction' trials at their maximal self-preferred speed. The maximal knee flexion angle and the valgus moment of the right knee during the weight acceptance phase were analysed. MRI data (T2 relaxation time) of the ACL was also collected. Among the independent variables involved in the linear regression model, the association of the valgus moment and sex were statistically significant (p = 0.01 and p = 0.001 respectively). In conclusion, the main finding of the study is that higher T2 was significantly associated with a higher valgus moment as acute response to the 'change in direction' tasks. New sentence: In conclusion, the main finding of the study is that higher T2 was significantly associated with a higher valgus moment during 'change in direction' tasks.

健康人前交叉韧带T2松弛时间与生物力学负荷的关系。

前交叉韧带（ACL）损伤在包括“改变方向”任务的运动中很常见。本研究的目的是确定ACL亚区远端部分的T2松弛时间（ACL完整性的一个指标）、ACL的生物力学负荷因素、性别和参与者的运动状态之间的关系。年龄在18到35岁之间的参与者以他们自己最喜欢的速度进行了意想不到的“方向改变”试验。分析了负重阶段右膝的最大屈曲角度和外翻力矩。同时收集前交叉韧带的MRI数据（T2松弛时间）。在线性回归模型的自变量中，外翻力矩与性别的相关性有统计学意义（p = 0.01和p = 0.001）。总之，本研究的主要发现是，高T2与高外翻力矩显著相关，作为对“改变方向”任务的急性反应。总之，这项研究的主要发现是，在“改变方向”任务中，较高的T2与较高的外翻力矩显著相关。

期刊介绍： Sports Biomechanics is the Thomson Reuters listed scientific journal of the International Society of Biomechanics in Sports (ISBS). The journal sets out to generate knowledge to improve human performance and reduce the incidence of injury, and to communicate this knowledge to scientists, coaches, clinicians, teachers, and participants. The target performance realms include not only the conventional areas of sports and exercise, but also fundamental motor skills and other highly specialized human movements such as dance (both sport and artistic). Sports Biomechanics is unique in its emphasis on a broad biomechanical spectrum of human performance including, but not limited to, technique, skill acquisition, training, strength and conditioning, exercise, coaching, teaching, equipment, modeling and simulation, measurement, and injury prevention and rehabilitation. As well as maintaining scientific rigour, there is a strong editorial emphasis on ''reader friendliness''. By emphasising the practical implications and applications of research, the journal seeks to benefit practitioners directly. Sports Biomechanics publishes papers in four sections: Original Research, Reviews, Teaching, and Methods and Theoretical Perspectives.
