Thirteen young men completed a ten-week exercise training program on bicycle ergometers. Training sessions were conducted five days per week, with eight men randomly assigned to low-effort (LE) and five to high-effort (HE) regimens. LE participants worked continuously at 50% of their maximal oxygen intake (exercise HR congruent to 135 BPM); HE participants performed two minutes alternating work-rest intervals at 80% of their maximal oxygen intake (exercise HR congruent to 170 BPM). Total work done was held constant for the two groups. LE and HE participants increased maximal oxygen intake (P < .01), but there was no difference in changes between the two groups. LE exercise training programs are more comfortable for participants and perhaps should be recommended over HE programs for most individuals, since improvements in physical fitness appear to be comparable.
13名年轻男性完成了一项为期10周的自行车测力计运动训练计划。训练课程每周进行5天，8名男性被随机分配到低强度（LE）训练组，5名男性被分配到高强度（HE）训练组。LE组参与者以其最大摄氧量的50%持续工作（运动心率相当于135次/分钟）；HE组参与者以其最大摄氧量的80%进行两分钟的交替工作-休息间隔训练（运动心率相当于170次/分钟）。两组的总工作量保持恒定。LE组和HE组参与者的最大摄氧量均有所增加（P < 0.01），但两组之间的变化没有差异。LE运动训练计划对参与者来说更舒适，也许对于大多数人而言，应该推荐LE计划而非HE计划，因为身体素质的改善似乎相当。
