The aim of this study was to analyze the effects of recovery mode (active/passive) on time spent at high percentage of maximal oxygen uptake (VO2max) i.e. above 90% of VO2max (t90VO2max) and above 95% of VO2max (t95VO2max) during a single short intermittent session. Eight endurance-trained male adolescents (15.9 +/- 1.4 years) performed three field tests until exhaustion: a graded test to determine their VO2max (57.4 +/- 6.1 ml min(-1) kg(-1)), and maximal aerobic velocity (MAV; 17.9 +/- 0.4 km h(-1)), and in a random order, two intermittent exercises consisting of repeated 30 s runs at 105% of MAV alternated with 30 s passive (IE(P)) or active recovery (IE(A), 50% of MAV). Time to exhaustion (t(lim)) was significantly longer for IE(P) than for IE(A) (2145 +/- 829 vs. 1072 +/- 388 s, P < 0.01). No difference was found in t90VO2max and t95VO2max between IE(P) (548 +/- 499-316 +/- 360 s) and IE(A) (746 +/- 417-459 +/- 332 s). However, when expressed as a percentage of t(lim), t90VO2max and t95VO2max were significantly longer (P < 0.001 and P < 0.05, respectively) during IE(A) (67.7 +/- 19%-42.1 +/- 27%) than during IE(P) (24.2 +/- 19%-13.8 +/- 15%). Our results demonstrated no influence of recovery mode on absolute t90VO2max or t95VO2max mean values despite significantly longer t(lim) values for IE(P) than for IE(A). In conclusion, passive recovery allows a longer running time (t(lim)) for a similar time spent at a high percentage of VO2max.
本研究的目的是分析恢复模式（主动/被动）对单次短时间间歇训练期间在最大摄氧量（VO2max）高百分比水平，即高于VO2max的90%（t90VO2max）和高于VO2max的95%（t95VO2max）时所花费时间的影响。八名耐力训练的男性青少年（15.9±1.4岁）进行了三次直至力竭的现场测试：一次分级测试以确定他们的VO2max（57.4±6.1毫升·分钟⁻¹·千克⁻¹）和最大有氧速度（MAV；17.9±0.4千米·小时⁻¹），然后以随机顺序进行两次间歇运动，包括以MAV的105%重复进行30秒跑步，中间交替30秒的被动恢复（IE(P)）或主动恢复（IE(A)，MAV的50%）。IE(P)的力竭时间（t(lim)）显著长于IE(A)（2145±829秒对1072±388秒，P<0.01）。在IE(P)（548±499 - 316±360秒）和IE(A)（746±417 - 459±332秒）之间，t90VO2max和t95VO2max未发现差异。然而，当以t(lim)的百分比表示时，IE(A)期间（67.7±19% - 42.1±27%）的t90VO2max和t95VO2max显著长于IE(P)期间（24.2±19% - 13.8±十五%）（分别为P<0.001和P<0.05）。我们的结果表明，尽管IE(P)的t(lim)值显著长于IE(A)，但恢复模式对绝对t90VO2max或t95VO2max平均值没有影响。总之，被动恢复在VO2max高百分比水平下花费相似时间的情况下允许更长的跑步时间（t(lim)）。
