The study aimed to compare the physiological and perceptual responses of two high intensity intermittent aerobic exercises (HIIE), i.e. the 15s/15s exercise and an exercise on the Hoff track (HTE).
In this within-subject repeated measures study, seven high-level soccer players (Age: 24.1± 4.5yr; Height: 175± 0.04cm; Body mass: 67.9± 9.0kg;% Body fat: 14.2± 2.4%) performed the two exercises with same total duration (25 minutes) in a randomized order: 1) a 15s/15s protocol at 120% of maximal aerobic speed (MAS), and 2) HTE. Heart rate (HR) and oxygen uptake (VO2) were measured continuously throughout both exercises. The rating of perceived exertion (RPE) was measured 15 min after the end of each exercise. Blood lactate concentration ([La]) was measured at rest before each exercise, between and at the end of each set.
The mean VO2 during HTE was significantly higher than 15s/15s exercise (39.3±2.3 vs. 36.8±1.9 mL/min/kg, P<0.05. The total O2 consumed was significantly higher (P<0.05) during HTE (66.8±7.6 L) than during the 15s/15s (62.3±8.6 L). Blood lactate [La] after the first set of HTE was significantly higher than the 15s/15s (12.5±2.0 vs. 10.6±2.0 mmol/L, P<0.05). However, RPE provided by players suggested that the 15s/15s was more intense than the HTE (13±1.8 vs. 11.7±1.4, P<0.05).
Our results demonstrate that VO2 and [La] were higher during HTE than during the 15s/15s when matched with duration. However, HTE was perceived less intense than 15s/15s. Thus, the use of HTE appears as an effective alternative for fitness coaches to develop aerobic endurance in soccer players.
本研究旨在比较两种高强度间歇有氧运动（HIIE），即15秒/15秒运动和霍夫跑道运动（HTE）的生理和感知反应。
在这项受试者内重复测量研究中，七名高水平足球运动员（年龄：24.1±4.5岁；身高：175±0.04厘米；体重：67.9±9.0千克；体脂百分比：14.2±2.4%）以随机顺序进行了两种总时长相同（25分钟）的运动：1）以最大有氧速度（MAS）的120%进行15秒/15秒方案，以及2）HTE。在两项运动过程中持续测量心率（HR）和摄氧量（VO2）。在每次运动结束后15分钟测量主观用力程度（RPE）。在每次运动前休息时、每组运动之间以及每组运动结束时测量血乳酸浓度（[La]）。
HTE期间的平均VO2显著高于15秒/15秒运动（39.3±2.3对36.8±1.9毫升/分钟/千克，P<0.05）。HTE期间消耗的总氧气量（66.8±7.6升）显著高于15秒/15秒运动期间（62.3±8.6升）（P<0.05）。第一组HTE后的血乳酸[La]显著高于15秒/15秒运动（12.5±2.0对10.6±2.0毫摩尔/升，P<0.05）。然而，运动员提供的RPE表明15秒/15秒运动比HTE更剧烈（13±1.8对11.7±1.4，P<0.05）。
我们的结果表明，在时长匹配时，HTE期间的VO2和[La]高于15秒/15秒运动期间。然而，HTE的剧烈程度被认为低于15秒/15秒运动。因此，对于体能教练来说，使用HTE似乎是培养足球运动员有氧耐力的一种有效替代方法。
