Adrenaline, noradrenaline, glucose, glycerol and the free fatty acids (FFA) in the blood, as well as the heart rate and oxygen intake, were tested in six healthy male volunteers (age: 28 +/- 6 years) during graduated (I) and continuously (II) increasing bicycle ergometric exercise (upright body position). The maximum heart rate, the VO2 max, the maximum lactate and FFA concentration show no significant difference, whereas adrenaline, noradrenaline and the glucose levels are significantly lower, and the glycerol concentration is slightly higher during the maximum test II as compared with test I. At some submaximum exercise levels, the lactate concentration and the heart rate are slightly lower, adrenaline and noradrenaline are significantly lower during test II; the FFA, glycerol and the oxygen intake do not show any significant difference. The duration of exercise was similar in both tests. The total work was about 50% lower in test II, and the maximum performance was slightly higher as compared with test I. These results could have significance for the planning of working conditions, the rehabilitation of patients, and the organisation of training for athletes.
在六名健康男性志愿者（年龄：28±6岁）进行分级（I）和持续（II）递增的自行车测力计运动（身体直立姿势）期间，对其血液中的肾上腺素、去甲肾上腺素、葡萄糖、甘油和游离脂肪酸（FFA）以及心率和氧气摄入量进行了测试。最大心率、最大摄氧量、最大乳酸和FFA浓度无显著差异，而与测试I相比，在最大测试II期间，肾上腺素、去甲肾上腺素和葡萄糖水平显著降低，甘油浓度略高。在一些次最大运动水平下，测试II期间乳酸浓度和心率略低，肾上腺素和去甲肾上腺素显著降低；FFA、甘油和氧气摄入量无显著差异。两次测试的运动持续时间相似。测试II中的总工作量比测试I低约50%，最大表现略高于测试I。这些结果可能对工作条件规划、患者康复以及运动员训练组织具有重要意义。
