Anterior cruciate ligament (ACL) injuries in basketball appear to be more common when players are in possession of the ball. The greater risk of ACL injury when in possession of the ball may result from the athlete's inability to fully attend to their movement. However, it is also possible that having to carry/manipulate the ball restricts the athlete's ability to utilise their upper extremities for stability during a manoeuvre. The purpose of this study was to explore how possession of a basketball and divided attention influence lower extremity mechanics during cutting and landing. Twenty uninjured females with basketball experience performed a baseline lateral cutting task, as well as lateral cuts while carrying a basketball, with and without a subsequent chest pass. Requiring participants to carry the basketball in isolation (i.e., without the additional pass) had minimal influence on lower extremity mechanics compared to baseline. However, participants demonstrated less knee flexion (40.9° vs. 47.3°) and greater knee abduction (12.2° vs. 10.1°) for trials that included the additional pass (divided attention condition) compared to trials conducted while carrying the basketball in isolation. Athletes may be at greater risk for ACL injury when they are unable to solely attend to their movement.
篮球运动中,当球员控球时,前交叉韧带(ACL)损伤似乎更为常见。控球时ACL损伤风险更高,可能是因为运动员无法充分关注自身动作。然而,也有可能是因为在动作过程中,持球/操控球限制了运动员利用上肢保持稳定的能力。本研究的目的是探讨持球和注意力分散如何影响切入和落地时的下肢力学。20名有篮球经验的未受伤女性进行了一项基线侧向切入任务,以及在持球情况下进行侧向切入,且分别有无随后的胸前传球。与基线相比,要求参与者单独持球(即无额外传球)对下肢力学影响极小。然而,与单独持球进行的试验相比,在包含额外传球(注意力分散情况)的试验中,参与者表现出更小的屈膝角度(40.9°对47.3°)和更大的膝外展角度(12.2°对10.1°)。当运动员无法完全专注于自身动作时,他们面临ACL损伤的风险可能更高。
