(1)极限飞盘涉及频繁的切割动作，这有很高的前十字韧带（ACL）损伤的风险，特别是对女性球员。本研究调查了女性极限飞盘运动员在比赛中进行的切割动作，以了解可能使她们处于ACL损伤风险中的动作。(2)在16场联盟认可的极限飞盘比赛中，12名女选手佩戴的可穿戴下半身惯性传感器重建了下半身运动学和场地周围的运动。(3)根据速度和方向变化标准识别出422个切口。平均截骨的入路速度为3.4 m/s，入路加速度为3.1 m/s2，截骨角度为94 °，地面接触膝关节屈曲度为34 °。从30到90度的浅切是最常见的。速度和加速度不因切割角度而改变。在更具竞争力的球队中，球员的速度和加速度更高，在切割过程中膝盖弯曲度降低。(4)这项研究表明，下半身一组可穿戴惯性传感器可以成功地跟踪运动员的运动在真实的游戏，产生详细的生物力学指标的行为和性能。这些游戏中的测量结果可用于在未来的实验室研究中指定受控的切割运动。这些研究应该优先考虑高水平的球员，因为他们可能会表现出更高的风险切割行为。
(1) Ultimate frisbee involves frequent cutting motions, which have a high risk of anterior cruciate ligament (ACL) injury, especially for female players. This study investigated the in-game cutting maneuvers performed by female ultimate frisbee athletes to understand the movements that could put them at risk of ACL injury. (2) Lower-body kinematics and movement around the field were reconstructed from wearable lower-body inertial sensors worn by 12 female players during 16 league-sanctioned ultimate frisbee games. (3) 422 cuts were identified from speed and direction change criteria. The mean cut had approach speed of 3.4 m/s, approach acceleration of 3.1 m/s2, cut angle of 94 degrees, and ground-contact knee flexion of 34 degrees. Shallow cuts from 30 to 90 degrees were most common. Speed and acceleration did not change based on cut angle. Players on more competitive teams had higher speed and acceleration and reduced knee flexion during cutting. (4) This study demonstrates that a lower-body set of wearable inertial sensors can successfully track an athlete’s motion during real games, producing detailed biomechanical metrics of behavior and performance. These in-game measurements can be used to specify controlled cutting movements in future laboratory studies. These studies should prioritize higher-level players since they may exhibit higher-risk cutting behavior.
