Abstract

The current study sought to compare single leg (SL) landing and cutting mechanics within a cohort of youth footballers. A secondary aim was to examine how task complexity modulates the relationship between maturation and performance. Thirty-nine soccer players from an English football academy were categorised as pre-, circa- and post-peak height velocity (PHV). As part of routine club testing, players performed 1) bilateral and SL jumps (countermovement jump (CMJ) and 10/5 rebound jump tests), 2) speed (30-m sprint), and 3) change of direction (COD; 505 test and 45° cut) assessments. Landing (LESS score) and cutting mechanics (CMAS score) were determined during SL CMJ and 45° cuts, respectively. Differences in landing mechanics were not observed between groups. However, large effect sizes indicated that CMAS scores were lower in the post-PHV group versus pre- and circa-PHV groups, indicative of a favourable cutting technique. The circa-PHV group outperformed the pre-PHV group in the 'simpler' bilateral CMJ and linear sprint assessments, but not in the SL CMJ, 10/5 or COD assessments. The observed variability between participants in the circa-PHV period could be interpreted by changes in coordinative abilities. It is possible that athletes may require closer monitoring and possible training modification during this phase.

青少年足球运动中协调能力受损吗?
目前的研究试图比较一群青少年足球运动员的单腿着地和切球力学。第二个目的是研究任务复杂性如何调节成熟度和绩效之间的关系。来自英国足球学院的39名足球运动员被分为高峰前、高峰前后和高峰后高度速度(PHV)。作为常规球杆测试的一部分,参与者进行了1)双侧和侧侧跳(反向跳(CMJ)和10/5反弹跳测试),2)速度(30米冲刺)和3)方向变化(COD;505测试和45°切割)评估。在SL CMJ和45°切削时分别测定着陆(LESS评分)和切削力学(CMAS评分)。各组间未观察到着陆力学的差异。然而,大效应量表明,与phv前和phv前后组相比,phv后组的CMAS评分较低,表明有利的切割技术。circa-PHV组在“更简单”的双侧CMJ和线性冲刺评估中表现优于pre-PHV组,但在SL CMJ、10/5或COD评估中表现不佳。在circa-PHV期间,观察到的参与者之间的差异可以通过协调能力的变化来解释。在这个阶段,运动员可能需要更密切的监测和可能的训练修改。

期刊介绍: The Journal of Sports Sciences has an international reputation for publishing articles of a high standard and is both Medline and Clarivate Analytics-listed. It publishes research on various aspects of the sports and exercise sciences, including anatomy, biochemistry, biomechanics, performance analysis, physiology, psychology, sports medicine and health, as well as coaching and talent identification, kinanthropometry and other interdisciplinary perspectives. The emphasis of the Journal is on the human sciences, broadly defined and applied to sport and exercise. Besides experimental work in human responses to exercise, the subjects covered will include human responses to technologies such as the design of sports equipment and playing facilities, research in training, selection, performance prediction or modification, and stress reduction or manifestation. Manuscripts considered for publication include those dealing with original investigations of exercise, validation of technological innovations in sport or comprehensive reviews of topics relevant to the scientific study of sport.
