The objective of this study was to investigate the potential variations in cardiorespiratory and metabolic parameters and running performance among 3 modes of exercise of the same duration, namely, intermittent running with active recovery (AR) or passive recovery (PR) and continuous running (CR) and whether these variations could affect passive recovery time (PRT). Fifteen male physical education students with a subspecialty in soccer were studied (mean age 22.3 ± 2.5 years, training experience 12.3 ± 2.5 years) in the middle of the playing season. The results showed that during exercise, the highest heart rate (HR) and VO2 values were observed in CR, whereas the lowest values in PR followed by AR. Blood lactate (BLa) concentration was higher in PR by 38% compared to that in AR (p < 0.05). The exercise duration was similar between PR and AR tests and longer than in CR. With regard to PRT, the highest HR (186 ± 9 b · min(-1)), VO2 (55.5 ± 5.2 ml · kg(-1) · min(-1)), and BLa (5.1 ± 1.7 mmol · L(-1)) values were found in CR. No differences in HR and VO2 between PR and AR were detected. However, despite the differences in BLa concentration between AR and PR during exercise, the PRT BLa values between these 2 exercise modes were not different. Among the 3 running protocols, only CR appeared to have fully challenged the cardiorespiratory system inducing maximal HR and VO2 responses during exercise and high BLa values in PRT, yet these responses were not associated with better exercise performance compared to intermittent running. Therefore, intermittent exercise, regardless of implementing passive or active interval, might be the preferable exercise mode particularly in activities extended over 30 minutes.
本研究旨在探究在相同时长下三种运动模式（间歇跑加主动恢复、间歇跑加被动恢复和持续跑）的心肺和代谢参数以及跑步表现的潜在差异，以及这些差异是否会影响被动恢复时间。研究对象为 15 名有足球专项的男性体育系学生（平均年龄 22.3 ± 2.5 岁，训练经验 12.3 ± 2.5 年），他们在赛季中期进行了研究。结果表明，在运动过程中，持续跑的最高心率（HR）和最大摄氧量（VO2）最高，而被动恢复跑的最低 HR 和 VO2 随后是主动恢复跑。与主动恢复跑相比，被动恢复跑的血乳酸（BLa）浓度高 38%（p < 0.05）。PR 和 AR 测试的运动时间相似，比 CR 测试的运动时间长。关于 PRT，CR 的 HR（186 ± 9 b · min(-1)）、VO2（55.5 ± 5.2 ml · kg(-1) · min(-1)）和 BLa（5.1 ± 1.7 mmol · L(-1)）最高。PR 和 AR 之间的 HR 和 VO2 没有差异。然而，尽管运动中 AR 和 PR 的 BLa 浓度存在差异，但这两种运动模式的 PRT BLa 值没有差异。在这三种跑步方案中，只有 CR 似乎完全挑战了心肺系统，在运动过程中产生了最大的 HR 和 VO2 反应，并在 PRT 中产生了较高的 BLa 值，但与间歇跑相比，这些反应并没有带来更好的运动表现。因此，间歇运动，无论采用主动还是被动间歇，都可能是一种更受欢迎的运动模式，特别是在持续 30 分钟以上的活动中。
