ObjectivesTo determine if preseason lower limb ROM，flexibility，and strength different in collegiate gymnasts（NCAA Division 1）who do or not sustain a injury during competitive season.MethodsOver four seasons，a total of 15 female gymnasts（age = 20.5 ± 1.0 years）undergoes preseason screening（30 gymnasts-season）.我们测试了关节ROM（髋关节：屈曲、内旋和外旋;踝关节：负重背屈）、肌肉柔韧性（被动直腿抬高、托马斯、奥伯、伊利试验）和力量（通过手持式测力计测量髋伸肌、外展肌和屈肌等长力量;膝关节：股四头肌和腿筋等速力量，60°/秒）。团队运动教练在每个赛季跟踪过度使用下肢损伤（限制体操运动员充分参与，发生在参加有组织的练习或比赛，并需要医疗护理）。对于测试多个赛季的运动员，每次遭遇都被认为是独立的，每次季前赛评估都与同一个竞争赛季中的过度使用损伤有关。体操运动员被分为受伤组和非受伤组。一个独立的t检验被用来衡量受伤和非受伤groups.ResultsDuring四年，我们记录了23过度使用下肢损伤季前赛的结果之间的差异。体操运动员持续在赛季过度使用损伤表现出显着较低的髋关节屈曲ROM（平均差异：−10.6°; 95%置信区间：−16.5，−4.6;p< 0.01）和髋关节外展力量较低（平均差异：体重的−4.7%; 95%置信区间：−9.2，−0.3;结论体操运动员在赛季过度使用下肢损伤后，季前赛髋关节屈曲ROM明显不足，髋关节外展肌无力。这些研究结果表明，在运动和动力链负责着陆过程中的技能表现和能量吸收的潜在障碍。
ObjectivesTo determine if preseason lower extremity ROM, flexibility, and strength differ in collegiate gymnasts (NCAA Division 1) who do or do not sustain an injury during the competitive season.MethodsOver four seasons, a total of 15 female gymnasts (age = 20.5 ± 1.0 years) underwent preseason screening (30 gymnast-season). We tested joint ROM (hip: flexion, internal and external rotation; ankle: weightbearing dorsiflexion), muscle flexibility (passive straight leg raise, Thomas,’ Ober’s, Ely’s tests) and strength (hip extensors, abductors, and flexors isometric strength via a handheld dynamometer; knee: quadriceps and hamstring isokinetic strength at 60°/sec). The team athletic trainer tracked overuse lower extremity injuries (restricted gymnasts from full participation, occurred as from participation in organized practice or competition, and required medical attention) during each season. For athletes that tested multiple seasons, each encounter was considered independent, and each preseason assessment was linked to overuse injuries sustained during the same competitive season. Gymnasts were dichotomized into injured and non-injured groups. An independent t-test was used to measure differences in preseason outcomes between injured and non-injured groups.ResultsDuring four years, we recorded 23 overuse lower extremity injuries. Gymnasts that sustained an in-season overuse injury demonstrated significantly lower hip flexion ROM (mean difference: −10.6°; 95% confidence interval: −16.5, −4.6;p< 0.01) and lower hip abduction strength (mean difference: −4.7% of body weight; 95% confidence interval: −9.2, −0.3;p= 0.04).ConclusionGymnasts who sustain an in-season overuse lower extremity injury have significant preseason deficit of hip flexion ROM and weakness in the hip abductors. These findings indicate potential impairments in the kinematic & kinetic chains responsible for skill performance and energy absorption during landing.
