Abstract

Aim: The hamstring strength training in youth soccer is relevant both for muscle injury prevention and for sprint performance increase. This study aim to assessment hamstring eccentric strength in young soccer players to know any lower limb strength asymmetries Methods: The sample is composed of male young soccer players Under 17 (n=14, 16,6±0,5 years, 175,8±7,1cm and 70,9±9,1 kg). To assess the hamstring eccentric strength and the lower limb eccentric strength asymmetry have been used a specific dynamometer (NordBord Hamstring Testing System, Vald Performance, Australia) with software. Every young soccer player performed a single repetition of the Nordic hamstring exercise with constraint to the Nord Bord; after about 10 minutes, instead, they performed 5 repetitions of the same exercise, without interruption. All values were acquired using NordBord software: for both assessments, were detected the eccentric strength and the lower limbs strength asymmetry. Results: The evaluation of the hamstring eccentric strength does not show substantial and statistically significant differences in the single test with reference to the peak parameter. In the comparison between the average eccentric strength expressed in the 5 repetitions there is a statistically significant difference between the values expressed by the two limbs (p<0-05), and an increase in the value asymmetry is observed (15,8±5,4%). Conclusion: This difference between the two tests leads us to think that the fatigue potential effect on the hamstring muscles deriving from the number of repetitions requested, can accentuate and highlight to a greater extent the differences between the hamstrings of the two lower limbs in the young player.
腿筋损伤预防:青少年足球运动员的力量评估
目的:青少年足球运动中腘绳肌力量训练对预防肌肉损伤和提高短跑成绩具有重要意义。方法:选取17岁以下男性青少年足球运动员(n=14、16、6±0、5岁、175、8±7、1cm和70、9±9、1 kg)为研究对象。为了评估腿筋偏心强度和下肢偏心强度不对称性,我们使用了一种特殊的测功仪(澳大利亚Vald Performance公司的nordboard腿筋测试系统),并使用软件。每个年轻的足球运动员都要重复一次北欧腿筋练习,并限制北板;大约10分钟后,他们做了5次同样的练习,没有中断。所有数值均使用nordboard软件获取:对于两种评估,均检测偏心强度和下肢强度不对称。结果:参考峰值参数,单次试验对腘绳肌偏心强度的评价无实质性、统计学差异。在5次重复表示的平均偏心强度比较中,两肢表示的数值差异有统计学意义(p<0-05),数值不对称性增加(15.8±5.4%)。结论:这两项测试的差异使我们认为,由重复次数引起的腘绳肌疲劳潜在影响,更大程度上强调和突出了年轻运动员下肢腘绳肌的差异。
