To describe the perceived load, fatigue and recovery profiles during congested and non-congested schedules in international football tournaments.
Retrospective single-cohort observational study.
Internal load (session-rating of perceived exertion [s-RPE]) and perceived ratings of fatigue, muscle soreness, psychological status, sleep quality, and sleep duration were recorded daily from 37 national team footballers during the competition phase of 3 international tournaments. ANOVA and Effect Size (ES) analyses compared individualised internal load and perceived response profiles between congested and non-congested acute 2-match schedules. Conditions included Acute Congestion (≤4 days between two matches), Non-Congestion (>4 days between two matches), Single-Match, and No-Match.
Significantly higher s-RPE match loads (p < 0.001) within the single- and multi-match conditions resulted in significantly worsened (p < 0.05) subjective ratings of perceived fatigue, muscle soreness and sleep duration in the 24-48 h post-match. Internal load profiles were not different between the Acute-Congestion or Non-congestion conditions (p > 0.05); though Acute-Congestion had significantly worsened pre-match subjective ratings compared to Non-Congestion on both MD1 (p = 0.040; ES = 0.94) and MD2 (p = 0.033; ES = 0.94). However, between-match differences in Acute-Congestion showed no further impairments in perceived response between the first and second matches (p > 0.05).
During international tournaments, internal load and perceived fatigue/recovery profiles are largely determined by their exposure (or lack thereof) to match-play. Periods of acute match congestion impaired players pre-match perceived status when compared to non-congested microcycles. However, acute match congestion does not appear to exacerbate players post-match fatigue/recovery response within the context of international football tournaments.
描述国际足球比赛中密集赛程和非密集赛程期间的感知负荷、疲劳和恢复情况。
回顾性单队列观察研究。
在 3 项国际比赛的比赛阶段，37 名国家队足球运动员每天记录内部负荷（赛中感觉努力评分[s-RPE]）和感知疲劳、肌肉酸痛、心理状态、睡眠质量和睡眠时间的评分。通过 ANOVA 和效应量（ES）分析，比较了密集和非密集的急性 2 场比赛赛程下的个体化内部负荷和感知反应情况。条件包括急性拥挤（2 场比赛之间≤4 天）、非拥挤（2 场比赛之间>4 天）、单场比赛和无比赛。
单场和多场比赛条件下的 s-RPE 比赛负荷明显更高（p<0.001），导致赛后 24-48 小时的主观疲劳、肌肉酸痛和睡眠持续时间评分明显恶化（p<0.05）。急性拥挤和非拥挤条件下的内部负荷模式没有差异（p>0.05）；尽管急性拥挤在 MD1（p=0.040；ES=0.94）和 MD2（p=0.033；ES=0.94）上的比赛前主观评分明显差于非拥挤，但在 MD1 和 MD2 上没有进一步的感知反应损伤。
在国际比赛中，内部负荷和疲劳/恢复感知主要取决于他们是否（或缺乏）接触比赛。与非拥挤的微周期相比，急性比赛拥挤会损害比赛前运动员的感知状态。然而，在国际足球比赛的背景下，急性比赛拥挤似乎不会加剧运动员赛后的疲劳/恢复反应。
