摘要

本研究旨在确定有氧和无氧代谢能力对悠悠球间歇恢复2级(悠悠球IR2)测试成绩的影响。19 名澳大利亚休闲足球运动员完成了悠悠球 IR2 测试,并在另一天以随机平衡的顺序完成了跑步机峰值摄氧量(VO2peak)和最大累积缺氧测试。最大累积氧耗量(MAOD)测试包括 5 × 5 分钟的次最大值连续跑,速度逐渐增加,同时记录 VO2;之后,速度逐渐增加,以达到 VO2 峰值。休息 35 分钟后,参与者以相当于 VO2 峰值 115% 的速度奔跑,直至筋疲力尽,此时收集呼出的空气以确定最大累积缺氧量。使用皮尔逊相关性和部分相关性评估变量之间的关系。最大有氧速度、相对强度和 VO2 峰值与悠悠球 IR2 成绩有显著相关性。高悠悠IR2表现者的MAS、相对强度和VO2峰值水平也较高。然而,当有较高的最大有氧速度、相对强度和 VO2 峰相互控制并进行独立分析时,最大有氧速度和 VO2 峰均与悠悠球 IR2 成绩无关。悠悠IR2成绩是多个变量之间复杂相互作用的结果。训练计划应主要侧重于提高 VO2 峰、最大有氧速度和相对强度,以优化悠悠球 IR2 测试成绩。

Anaerobic and Aerobic Metabolic Capacities Contributing to Yo-Yo Intermittent Recovery Level 2 Test Performance in Australian Rules Footballers
This study aimed to identify the aerobic and anaerobic metabolic performance capacities contributing to Yo-Yo Intermittent Recovery level 2 (Yo-Yo IR2) test performance. Nineteen recreational Australian footballers completed a Yo-Yo IR2 test, and on another day a treadmill peak oxygen uptake (VO2peak) and maximal accumulated oxygen deficit test in a randomised counter-balanced order. The maximal accumulated oxygen deficit (MAOD) procedures included 5 × 5 min sub-maximal continuous runs at progressively higher speeds whilst VO2 was recorded; thereafter, speed was incrementally increased to elicit VO2peak. After 35 min of rest, participants ran at a speed equivalent to 115% of VO2peak until exhaustion, at which point expired air was collected to determine maximal accumulated oxygen deficit. Relationships between variables were assessed using Pearson’s correlation and partial correlations. Maximum aerobic speed, relative intensity, and VO2peak were significantly correlated with Yo-Yo IR2 performance. High Yo-Yo IR2 performers also had higher MAS, relative intensity, and VO2peak levels. However, when higher maximum aerobic speed, relative intensity, and VO2peak were controlled for each other and analysed independently, neither maximal aerobic speed nor VO2peak correlated with Yo-Yo IR2 performance. Yo-Yo IR2 performance is the result of a complex interaction between several variables. Training programs should primarily focus on improving VO2peak, maximal aerobic speed, and relative intensity to optimize Yo-Yo IR2 test performance.
