Six males and seven females trained 3 d per wk (30 min at 80 to 85% heart rate reserve) for 20 wk on a leg press apparatus. A progressive exercise test was administered on a cycle ergometer, leg press apparatus, and treadmill before and after training. Before training, peak oxygen consumption (VO2, ml X kg-1 X min-1) during the leg press test was higher for the males (23.9 +/- 1.60, mean +/- SE) compared to the females (19.5 +/- 2.40, P less than or equal to 0.05). Peak VO2 during the cycling (males = 36.6 +/- 2.65, females = 28.5 +/- 2.35) and treadmill (males = 39.8 +/- 2.04, females = 33.2 +/- 2.64) tests was also different between the sexes, and 30 to 40% higher than during the leg press test (P less than or equal to 0.05). Peak heart rate (beats X min-1) was not different between the sexes (P greater than 0.05), yet was 11% lower during the leg press test (165 +/- 3.5) compared to the cycling (184 +/- 2.8) and treadmill (187 +/- 1.3) tests (P less than or equal to 0.05). After training, peak VO2 during the cycling and treadmill tests increased 10 to 15%, compared to 35% during the leg press test (P less than or equal to 0.05). The only change in peak heart rate was a 6% increase during the leg press test (P less than or equal to 0.05). Although peak VO2 on the leg press apparatus was lower than on the cycle ergometer and treadmill, leg press exercise elicited a sufficient stimulus for increasing peak VO2 on the three testing modes.
6名男性和7名女性每周训练3天（以心率储备的80%至85%进行30分钟训练），在腿举器械上训练20周。在训练前后，分别在自行车测力计、腿举器械和跑步机上进行递增运动测试。训练前，男性在腿举测试中的峰值耗氧量（VO2，毫升×千克⁻¹×分钟⁻¹）（23.9±1.60，平均值±标准误）高于女性（19.5±2.40，P≤0.05）。在自行车测试（男性=36.6±2.65，女性=28.5±2.35）和跑步机测试（男性=39.8±2.04，女性=33.2±2.64）中，男女之间的峰值VO2也存在差异，且比腿举测试时高30%至40%（P≤0.05）。男女之间的峰值心率（次×分钟⁻¹）没有差异（P＞0.05），但与自行车测试（184±2.8）和跑步机测试（187±1.3）相比，腿举测试时的峰值心率低11%（165±3.5）（P≤0.05）。训练后，自行车和跑步机测试中的峰值VO2增加了10%至15%，而腿举测试中增加了35%（P≤0.05）。峰值心率的唯一变化是腿举测试时增加了6%（P≤0.05）。尽管腿举器械上的峰值VO2低于自行车测力计和跑步机，但腿举运动对在三种测试模式下提高峰值VO2产生了足够的刺激。
