Abstract:
The aim of the present study was to compare the coordination patterns and levels of coordination variability of healthy and injured runners with iliotibial band syndrome (ITBS). Sixty runners divided into four groups (15 healthy males, 15 healthy females, 15 males with ITBS and 15 females with ITBS) ran at a steady and freely chosen pace on an over-ground track, and their coordination patterns of the lower limbs were calculated during 10 running stances using the vector coding technique. Both male and female runners with ITBS showed a greater dominance of the pelvis segment and the anti-phase patterns in the frontal plane thigh-pelvis coupling (p = 0.001, η2 = 0.36). In addition, injured female runners showed a greater hip adduction dominance, whereas injured males presented a greater anti-phase pattern in the transverse plane-frontal plane hip coupling (p = 0.003, η2 = 0.08). The levels of coordination variability during running stance did not change between ITBS injured and healthy runners in any of the couplings. Currently injured runners with ITBS appeared to present altered coordination patterns on the hip couplings that were partly dependent on gender but did not lead to changes in the coordination variability levels.
摘要:
本研究的目的是比较健康和受伤的跑步者的协调模式和协调变异性水平。60名跑步者分为四组(15名健康男性,15位健康女性,15名患有ITBS的男性和15名患有ITBS的女性)在地面赛道上以稳定且自由选择的速度奔跑,使用向量编码技术在10个跑步姿势中计算了它们的下肢协调模式。患有ITBS的男性和女性跑步者在骨盆段和额面大腿-骨盆耦合中表现出更大的优势(p=0.001,η2=0.36)。此外,受伤的女性跑步者表现出更大的髋关节内收优势,而受伤的男性在横向平面-额叶平面髋关节耦合中表现出更大的反相位模式(p=0.003,η2=0.08)。在任何联轴器中,ITBS受伤的跑步者和健康的跑步者在跑步姿势期间的协调变异性水平都没有变化。目前,患有ITBS的受伤跑步者似乎在髋关节上表现出改变的协调模式,这部分取决于性别,但并未导致协调变异性水平的变化。
