Abstract

Purpose: This study aimed to (1) analyze the impact of a small-sided game training program in the locomotor profile of youth male soccer players (while interacting with the baseline level - higher and lower level); and (2) test the relationships between variation in locomotor profile and the accumulated demands in 3v3, 5v5 and match over the period of observation.

Methods: The cohort lasted 3-weeks. Twenty under-17 male amateur soccer players (16.8 ± 0.41 years; experience: 6.35 ± 0.67 years) were assessed twice for their final velocity at 30-15 intermittent fitness test (VIFT), peak speed at 30-m sprint test (PSS) and anaerobic speed reserve (ASR). The PSS was estimated using a Global Positioning System, while the VIFT was estimated using the maximum level attained by the players during the test. Based on the baseline levels, the scores were standardized using the Z-score. The total score of athleticism (TSA) was calculated per player to organize the players into two groups: lower TSA and higher TSA. Over the three weeks of observation, the small-sided games of 3v3 and 5v5 and match demands were monitored using polar team pro. The heart rate responses (mean and peak), distance covered (overall and split by speed thresholds), and peak speed in these games were obtained and summed over the weeks. The repeated measures ANCOVA tested the variations (time) of the locomotor profile of players while considering the baseline as covariable and the group as a factor. The Pearson-product correlation test analyzed the relationships between variations in locomotor profile (Δ, post-baseline) and the accumulated demands in 3v3, 5v5, and match.

Results: Between-groups analysis (lower TSA vs. higher TSA) revealed no significant differences on VIFT (p = 0.915), PSS (p = 0.269), ASR (p = 0.258) and TSA score (p = 0.138). Within-group (baseline vs. post-observation) analysis revealed significant difference on VIFT (p < 0.001), PSS (p = 0.008), while no significant differences were found on ASR (p = 0.949) and TSA score (p = 0.619). Significant correlations were found between ΔPSS and match total distance (r = 0.444; p = 0.050), match Z2 (r = 0.481; p = 0.032) and match Z3 (r = 0.454; p = 0.044). Significant correlations were found between ΔTSA and match total distance (r = 0.457; p = 0.043), match Z1 (r = 0.451; p = 0.046), match Z2 (r = 0.500; p = 0.025) and match Z3 (r = 0.468; p = 0.037).

Conclusion: Significant improvements were observed after the period of observation. However, the fitness baseline level and the accumulated training load in the small-sided games seem to have no significant impact on the observed improvements.

青少年男子足球运动员小边比赛训练计划的影响:运动轮廓的变化与基线水平和累积负荷的相互作用。
目的:本研究旨在(1)分析小型比赛训练计划对青少年男子足球运动员运动特征的影响(同时与基线水平-高水平和低水平相互作用);(2)在观察期间检验运动剖面的变化与3v3、5v5和match的累积需求之间的关系。方法:随访3周。17岁以下男子业余足球运动员20名(16.8±0.41岁);年龄:6.35±0.67岁),分别进行30-15间歇体能测试(VIFT)最终速度、30米冲刺测试(PSS)峰值速度和无氧速度储备(ASR)测试。PSS是使用全球定位系统估计的,而VIFT是使用玩家在测试期间达到的最高水平估计的。在基线水平的基础上,使用z分数对得分进行标准化。计算运动员运动能力总分(TSA),将运动员分为低TSA组和高TSA组。在为期三周的观察中,使用polar team pro对3v3和5v5的小型比赛和比赛需求进行了监测。这些游戏的心率反应(平均和峰值)、覆盖距离(总体和速度阈值分割)和峰值速度在几周内得到并求和。重复测量ANCOVA测试运动员运动轮廓的变化(时间),同时考虑基线为协变量,组为一个因素。Pearson-product相关检验分析了运动轮廓(Δ,基线后)的变化与3v3, 5v5和匹配的累积需求之间的关系。结果:组间分析(低TSA vs高TSA)显示,VIFT (p = 0.915)、PSS (p = 0.269)、ASR (p = 0.258)和TSA评分(p = 0.138)差异无统计学意义。组内(基线与观察后)分析显示VIFT有显著差异(p)。结论:观察期后观察到显著改善。然而,体能基线水平和累积训练负荷在小面比赛中似乎对观察到的改善没有显著影响。
