Abstract

We examined the sensitivity and time-course of recovery of neuromuscular and perceptual player monitoring measures to U-18 English Premier League academy football match play. Eighteen players performed maximal posterior chain, hip adductor and abductor isometric strength tests, countermovement jumps (CMJ) and provided self-report wellbeing scores around eight competitive league home games: 1 day before (MD-1), pre-match (MD-PRE), post-match (MD-POST) and two (MD+2) and three (MD+3) days post-match. A permutational multivariate analysis of variance and post hoc univariate analyses of variance were used to examine match-induced responses to monitoring variables. Between MD-1 and MD-POST, we observed small to moderate reductions to the adductor and abductor peak force and maximal impulse and IPCS peak force; small reductions to CMJ jump height (JH) (flight time), eccentric peak force and eccentric deceleration rate of force development and moderate to large reductions to perceived fatigue, muscle soreness and mood. No match-induced changes were observed for CMJ flight time: contraction time or eccentric duration. Posterior chain, abductor, CMJ and self-report measures normalised by MD+3 but adductor peak force remained compromised at MD+3 (ES = small). Posterior chain, adductor and abductor peak isometric force and maximal impulse; CMJ JH, eccentric peak force and eccentric deceleration rate of force development and perceived fatigue, muscle soreness and mood are sensitive to match-induced fatigue. Since adductor peak force remained compromised at MD+3, it is apparent that players might not achieve complete neuromuscular recovery within 3 days of match play, and that the adductor muscle group might be particularly vulnerable to match-induced fatigue.

摘要

我们研究了神经肌肉和感知球员监测指标对 U-18 英格兰超级联赛学院足球比赛的敏感性和恢复过程。18 名球员进行了最大后链、髋关节内收肌和外展肌等长力量测试、反跳(CMJ),并在 8 场主场联赛比赛前后提供自我报告的幸福感评分:比赛前一天(MD-1)、比赛前(MD-PRE)、比赛后(MD-POST)和比赛后第 2 天(MD+2)和第 3 天(MD+3)。采用置换多元方差分析和事后单变量方差分析来检查监测变量对比赛的反应。在 MD-1 和 MD-POST 之间,我们观察到内收肌和外展肌峰值力和最大冲量以及 IPCS 峰值力的小到中度降低;CMJ 跳高技术(JH)(飞行时间)、离心峰值力和离心力发展减速率的小降低,以及感知疲劳、肌肉酸痛和情绪的中到大降低。CMJ 飞行时间:收缩时间或离心时间没有观察到比赛引起的变化。后链、外展肌、CMJ 和自我报告的测量值在 MD+3 时正常化,但内收肌峰值力在 MD+3 时仍然受损(ES=小)。后链、内收肌和外展肌的最大等长力量和最大冲量;CMJ JH、离心峰值力和离心力发展减速率以及感知疲劳、肌肉酸痛和情绪对比赛引起的疲劳敏感。由于内收肌峰值力在 MD+3 时仍然受损,很明显,球员可能在比赛后 3 天内无法完全恢复神经肌肉功能,并且内收肌肌肉群可能特别容易受到比赛引起的疲劳的影响。
