The current study aimed to compare locomotive outputs across English U16, U18 and U23 academy soccer and investigate possible relationships with neuromuscular and aerobic capacities. Participants included 46 outfield players from an English Category Two soccer academy. Global positioning system (18 Hz) data were utilised to analyse locomotive outputs across twenty eleven-a-side matches in each age group. Maximal sprinting speed (MSS) and aerobic speed (MAS) were assessed at the beginning of the season. Absolute total distance (TD), high-speed running (HSR), acceleration and deceleration workloads were higher in U18’s and U23’s vs. U16’s (g = 1.09–2.58; p < 0.05), and absolute sprinting distances were higher in U23’s vs. U16’s (g = 0.96; p < 0.05). In addition, relative HSR outputs were higher in U23’s vs. U18’s (g = 1.84–2.07; p < 0.05). Across the whole cohort, players’ MSS was positively associated with absolute HSR and sprinting distances (ρ = 0.53–0.79; p < 0.05) but not with relative parameters. MAS was positively associated with total distance, decelerations, and both absolute and relative HSR outputs (ρ = 0.33–0.56; p < 0.05). Overall, absolute locomotive outputs were significantly higher in U23’s and U18’s vs. U16’s. Locomotive outputs were also associated with maximal sprinting and aerobic speeds. Thus, training programmes should be tailored to competition demands to optimally prepare each age group for competition and reflect the increasing demands of each level of competition. Further, improving physical fitness (speed and endurance) is likely to drive greater outputs in competition.

“小步,还是巨大的飞跃?” 比较U23,U18和U16英语学院足球的比赛要求以及它们与速度和耐力的关联

当前的研究旨在比较英国U16,U18和U23学院足球的机车输出,并研究其与神经肌肉和有氧运动能力之间的可能关系。参与者包括来自英国第二足球学校的46名外场球员。全球定位系统(18 Hz)数据用于分析每个年龄组中二十一次11场比赛的机车输出。在赛季开始时评估了最高冲刺速度(MSS)和有氧运动速度(MAS)。U18和U23的绝对总距离(TD),高速行驶(HSR),加速和减速工作负载比U16的更高(g = 1.09–2.58; p <0.05),U23和vs的绝对短跑距离更高。 U16(g = 0.96; p <0.05)。另外,U23的相对高铁输出比U18的高(g = 1.84–2.07; p <0.05)。在整个队列中,运动员的MSS与绝对HSR和冲刺距离呈正相关(ρ= 0.53-0.79; p <0.05),而与相对参数无关。MAS与总距离,减速度以及绝对和相对高铁输出都呈正相关(ρ= 0.33–0.56; p <0.05)。总体而言,U23和U18的绝对机车输出显着高于U16。机车输出还与最大的冲刺和有氧运动速度有关。因此,应根据竞争需求量身定制培训计划,以最佳地为每个年龄段的竞争做好准备,并反映出各个竞争水平的不断增长的需求。此外,提高体能(速度和耐力)可能会在比赛中带动更多的产出。运动员的MSS与绝对HSR和冲刺距离呈正相关(ρ= 0.53-0.79; p <0.05),但与相对参数无关。MAS与总距离,减速度以及绝对和相对高铁输出都呈正相关(ρ= 0.33–0.56; p <0.05)。总体而言,U23和U18的绝对机车输出显着高于U16。机车输出还与最大的冲刺和有氧运动速度有关。因此,应根据竞争需求量身定制培训计划,以最佳地为每个年龄段的竞争做好准备,并反映出各个竞争水平的不断增长的需求。此外,提高身体素质(速度和耐力)可能会在比赛中带动更多的产出。运动员的MSS与绝对HSR和冲刺距离呈正相关(ρ= 0.53-0.79; p <0.05),但与相对参数无关。MAS与总距离,减速度以及绝对和相对HSR输出均呈正相关(ρ= 0.33–0.56; p <0.05)。总体而言,U23和U18的绝对机车输出显着高于U16。机车输出还与最大的冲刺和有氧运动速度有关。因此,应根据竞争需求量身定制培训计划,以最佳地为每个年龄段的竞争做好准备,并反映出各个竞争水平的不断增长的需求。此外,提高体能(速度和耐力)可能会在比赛中带动更多的产出。MAS与总距离,减速度以及绝对和相对HSR输出均呈正相关(ρ= 0.33–0.56; p <0.05)。总体而言,U23和U18的绝对机车输出显着高于U16。机车输出还与最大的冲刺和有氧运动速度有关。因此,应根据竞争需求量身定制培训计划,以最佳地为每个年龄段的竞争做好准备,并反映出各个竞争水平的不断增长的需求。此外,提高体能(速度和耐力)可能会在比赛中带动更多的产出。MAS与总距离,减速度以及绝对和相对高铁输出都呈正相关(ρ= 0.33–0.56; p <0.05)。总体而言,U23和U18的绝对机车输出显着高于U16。机车输出还与最大的冲刺和有氧运动速度有关。因此,应根据竞争需求量身定制培训计划,以最佳地为每个年龄段的竞争做好准备,并反映出各个竞争水平的不断增长的需求。此外,提高体能(速度和耐力)可能会在比赛中带动更多的产出。机车输出还与最大的冲刺和有氧运动速度有关。因此,应根据竞争需求量身定制培训计划,以最佳地为每个年龄段的竞争做好准备,并反映出各个竞争水平的不断增长的需求。此外,提高体能(速度和耐力)可能会在比赛中带动更多的产出。机车输出还与最大的冲刺和有氧运动速度有关。因此,应根据竞争需求量身定制培训计划,以最佳地为每个年龄段的竞争做好准备,并反映出各个竞争水平的不断增长的需求。此外,提高体能(速度和耐力)可能会在比赛中带动更多的产出。
