摘要

研究背景:本研究采用哥本哈根内收肌锻炼法(CAE)和北欧腘绳肌锻炼法(NHE),旨在研究:1)CAE和NHE干预是否与非洲青年男子足球运动员内收肌和腘绳肌力量的提高有关;2)休息一段时间和二次干预后力量是否发生变化:研究设计:干预前-干预后研究:44名非洲精英男子学院球员(年龄为14.7±1.5 [12-18]岁)参加了每周两次的CAE和NHE干预训练,分别为期8周和10周,中间休息4周。采用混合效应线性回归模型测量了长杆内收肌挤压力量和俯卧位等长腿肌力量,以观察力量随时间的变化:结果:在每次干预中,分别有 96% 和 95% 的 CAE 和 NHE 课程完成,没有发生与执行练习有关的不良事件。内收肌挤压力量在第一次干预期间有所增加(基线为 3.23 [2.99-3.47] N/kg,干预后为 3.53 [3.30-3.76] N/kg,p=0.911),并在休息期(3.52 [3.27-3.76] N/kg,p=0.999)和第二次干预(3.60 [3.35-3.84] N/kg,p=0.002)后保持不变。腘绳肌力量在第一次干预期间有所改善(基线为 4.95 [4.42-5.49] N/kg,干预后为 5.48 [4.95-6.02] N/kg,P=0.002):CAE和NHE干预措施可在非洲精英学院实施,且依从性高。内收肌和腘绳肌力量在第一次干预中有所改善,但在第二次干预中没有进一步改善。因此,二次干预应包括增加运动量或负荷,以提高内收肌和腘绳肌的纵向力量:III级(队列研究)。

Implementing the Copenhagen Adductor Exercise and Nordic Hamstring Exercise in West African Academy Soccer Players: An Intervention Study.

Background: This study implemented the Copenhagen Adductor Exercise (CAE) and Nordic Hamstring Exercise (NHE) to examine 1) whether CAE and NHE interventions are associated with adductor and hamstring strength gains in youth African male soccer players and 2) whether strength changes after a rest period and secondary intervention.

Study design: Pre-post intervention study.

Methods: Forty-four African elite male academy players (age 14.7±1.5 [12-18] years) participated in twice weekly CAE and NHE interventions for 8- and 10-week periods separated by a 4-week rest. Long lever adductor squeeze strength and prone isometric hamstring strength were measured with mixed-effects linear regression models to observe strength changes over time.

Results: Ninety-six and 95% of CAE and NHE sessions were completed in each intervention, with no adverse events related to the execution of the exercises. Adductor squeeze strength increased during the first intervention (baseline 3.23 [2.99-3.47] N/kg, post-intervention 3.53 [3.30-3.76] N/kg, p=0.911) and was maintained following the rest period (3.52 [3.27-3.76] N/kg, p=0.999) and second intervention (3.60 [3.35-3.84] N/kg, p=0.002). Hamstring strength improved during the first intervention (baseline 4.95 [4.42-5.49] N/kg, post-intervention 5.48 [4.95-6.02] N/kg, p<0.001), decreased to baseline during the rest period (4.98 [4.44-5.53] N/kg, p=0.996), and did not improve during the second intervention (5.01 [4.46-5.55] N/kg, p=0.978).

Conclusion: CAE and NHE interventions can be implemented at an elite African academy with high compliance. Adductor and hamstring strength improved in the first intervention, with no further improvements in the second intervention. Secondary interventions therefore should include higher exercise volume or load to improve longitudinal adductor and hamstring strength.

Level of evidence: Level III (Cohort Study).
