Abstract

ABSTRACT This study investigates whether the presence of a previous lower limb injury influences “Lower limb asymmetry” (LLA) in elite basketball players. A prospective, longitudinal observational study was carried out with 13 players grouped based on lower limb injury history in the 3 months prior to the study (Injury = 7, non-injured = 6). A total of 68 measurements per player were collected over 3 months, using the “Inertial Measurement Unit (IMU)” device. The mean difference in, (i) % of step balance; (ii) the average of the number of impacts performed per minute during training and (iii) the player’s load was assessed. This intensive evaluation is in line with the assessment methodology proposed in the field of sports injury. Our results show no significant differences (p = 0.377) in the asymmetry of the step balance between players with/without a history of injury. However, there were differences when the player’s position was considered (p = 0.046). These findings confirm that the presence of a previous lower limb injury does not influence the asymmetry in lower limb step balance in male basketball players. For clinicians, the variables studied offer an indirect measurement of any capacity and/or deficit in the absorption of lower limb loads after an injury.

既往下肢损伤不会影响优秀篮球运动员的步态不对称:一项前瞻性纵向观察研究
摘要:本研究调查了先前下肢损伤的存在是否会影响精英篮球运动员的“下肢不对称”(LLA)。根据研究前3个月的下肢损伤史,对13名球员进行了前瞻性纵向观察研究(损伤 = 7、无损伤 = 6) 。使用“惯性测量单元(IMU)”设备,每个玩家在3个月内总共收集了68个测量值。阶跃平衡的平均差值,(i)%;(ii)训练期间每分钟冲击次数的平均值,以及(iii)评估球员的负荷。这种深入的评估符合运动损伤领域提出的评估方法。我们的结果显示没有显著差异(p = 0.377)在有/没有受伤史的球员之间的步进平衡的不对称性。然而,当考虑球员的位置时,存在差异(p = 0.046)。这些发现证实了先前下肢损伤的存在不会影响男性篮球运动员下肢步进平衡的不对称性。对于临床医生来说,所研究的变量提供了对受伤后下肢负荷吸收能力和/或不足的间接测量。
