This study analyzed the impact of performing four consecutive football matches separated by 48-72 hours during a FIFA tournament on physical load, technical performance and plasma markers of redox state, muscle damage and inflammation in elite female players. Forty-eight players from three national teams were evaluated at seven time points: before (baseline) and throughout the tournament (after each match and before two training sessions). Only data from players who played all matches were included in the analyses (N = 13). The players were divided into high-rank (N = 6) and low-rank (N = 7) team players according to FIFA standards. Plasma creatine kinase (CK), C-reactive protein (CRP), total antioxidant status (TAS), and uric acid (UA) were analyzed at the selected time points. Technical performance and physical load were also quantified according to team rank. Players from low-rank teams played significantly more time than high-rank players (85 ± 10 vs 67 ± 15 minutes; P = .02; d = 1.51). Low-rank team players presented higher values in technical performance actions than the high-rank team players, but most of the differences were explained by the longer match time played. UA content differed across the matches, increasing from baseline (F = 3.90; P = .01) and more in the high-rank team players (F = 20.46; P = .001), while CRP only differed across the matches (F = 2.66; P = .05), also increasing from baseline. A large time effect was shown for UA only in the high-rank players (η = 0.50; P = .02). Four consecutive matches did not result in considerable alterations in plasma stress markers, physical load, and technical performance in elite female football players from distinct rank levels.
本研究分析了在国际足联锦标赛期间,精英女足球运动员连续进行四场间隔48 - 72小时的足球比赛对身体负荷、技术表现以及氧化还原状态、肌肉损伤和炎症的血浆标志物的影响。对来自三支国家队的48名运动员在七个时间点进行了评估:比赛前(基线)以及整个锦标赛期间(每场比赛后和两次训练课之前)。分析仅纳入了参加所有比赛的运动员的数据(N = 13)。根据国际足联标准,将运动员分为高排名组(N = 6)和低排名组(N = 7)的队员。在选定的时间点分析血浆肌酸激酶(CK)、C反应蛋白(CRP)、总抗氧化状态(TAS)和尿酸(UA)。还根据球队排名对技术表现和身体负荷进行了量化。低排名组的队员上场时间明显多于高排名组队员(85 ± 10分钟对67 ± 15分钟;P = 0.02;d = 1.51)。低排名组队员在技术表现动作方面的值高于高排名组队员,但大多数差异可以用更长的比赛时间来解释。UA含量在各场比赛中有所不同,从基线开始增加(F = 3.90;P = 0.01),在高排名组队员中增加得更多(F = 20.46;P = 0.001),而CRP仅在各场比赛中有所不同(F = 2.66;P = 0.05),同样从基线开始增加。仅在高排名组队员中显示出UA有较大的时间效应(η = 0.50;P = 0.02)。连续四场比赛并未导致不同排名水平的精英女足球运动员的血浆应激标志物、身体负荷和技术表现出现显著变化。
