Abstract

Objective

The Copenhagen Adduction Exercise (CAE) has been studied in football players to determine its impact on strength gains. We aimed to examine the effects of the CAE on eccentric hip adduction (EHAD) strength and the eccentric adduction-to-abduction strength ratio in elite adolescent taekwondo athletes.

Materials and methods

Twenty-three elite taekwondo athletes (9 females, 14 males, mean age 16.43 ± 1.8 years) were included in the study. All athletes received progressive CAE training in addition to their regular taekwondo training for 8 weeks. Eccentric hip abduction (EHAB) and EHAD muscle strengths were assessed with a handheld dynamometer at baseline, at the 4th week and the 8th week.

Results

A significant main effect of time was observed, indicating that the dominant side EHAD strength (F_2,44 = 71.733, p < 0.001), EHAB strength (F_2,44 = 6.342, p = 0.004); EHAD/EHAB ratio (F_2,44 = 31.813, p < 0.001). The non-dominant side EHAD strength (F_2,44 = 87.308, p < 0.001); EHAB strength (F_2,44 = 6.825, p = 0.007); and EHAD/EHAB ratio (F_2,44 = 49.364, p < 0.001) also differed across time.

Conclusions

An eight-week progressive Copenhagen Adduction exercise significantly and clinically meaningfully increases EHAD strength, as well as improves the EHAD/EHAB ratio bilaterally among elite adolescent taekwondo athletes when implemented into the regular training.

优秀青少年跆拳道运动员进行为期8周的哥本哈根内收训练后，髋偏心内收和内收外展比的早期力量增加

目的研究足球运动员的哥本哈根内收练习（CAE），以确定其对力量增益的影响。我们的目的是研究CAE对优秀青少年跆拳道运动员偏心髋内收（EHAD）力量和偏心内收/外展力量比的影响。材料与方法选取优秀跆拳道运动员23名，其中女9名，男14名，平均年龄16.43±1.8岁。所有运动员在常规跆拳道训练的基础上接受渐进式CAE训练，为期8周。在基线、第4周和第8周用手持式测力仪评估偏心髋关节外展（EHAB）和EHAD肌肉力量。结果观察到时间的显著主效应，表明优势侧EHAD强度（F2,44 = 71.733, p < 0.001）、EHAB强度（F2,44 = 6.342, p = 0.004）；EHAD/EHAB比值（F2,44 = 31.813, p < 0.001）。非优势侧EHAD强度（F2,44 = 87.308, p < 0.001）；EHAB强度（F2,44 = 6.825, p = 0.007）；EHAD/EHAB比值（F2,44 = 49.364, p < 0.001）也存在时间差异。结论为期8周的渐进式哥本哈根内收训练，在常规训练中实施后，能显著提高优秀青少年跆拳道运动员的EHAD强度，并改善EHAD/EHAB比值。
