The aim of this experiment was to estimate the relative contribution of the various energy delivery systems during maximal exercise tests of short duration. Twenty-five males were submitted to a VO2max test and 10-, 30-, and 90-s maximal ergocycle tests. Expiratory gases were collected with a Douglas bag during the entire 30-s test and continuously monitored with an open-circuit system during the 90-s test. Estimates of the phosphagenic component represented approximately 55%-60% of the energy expenditure during the 10-s work performance. Results of the 30-s test indicated that the relative contributions of the energy systems were 23%, 49%, and 28% for the phosphagenic, glycolytic, and oxidative pathways, respectively. For the 90-s test, these estimates were 12%, 42%, and 46% for the three metabolic systems. The highest contribution of each system during the 90-s was obtained from 5 to 15 s for the phosphagenic component, from 16 to 30 s for the glycolytic, and from 61 to 75 s for the aerobic energy systems. During the 90-s test, VO2max was reached after approximately 60 s. It is concluded that the 30 and 90 s are not strictly anaerobic although they all have a large anaerobic component.
本实验的目的是评估在短时间最大运动测试期间各种能量供应系统的相对贡献。25名男性接受了最大摄氧量（VO2max）测试以及10秒、30秒和90秒的最大测力计测试。在整个30秒的测试过程中，用道格拉斯袋收集呼出气，并在90秒的测试过程中用开路系统进行连续监测。磷酸原成分的估计值约占10秒工作表现期间能量消耗的55%-60%。30秒测试的结果表明，能量系统的相对贡献分别为：磷酸原途径23%、糖酵解途径49%、氧化途径28%。对于90秒的测试，这三种代谢系统的估计值分别为12%、42%和46%。在90秒期间，每个系统的最大贡献时间分别为：磷酸原成分在5至15秒，糖酵解在16至30秒，有氧能量系统在61至75秒。在90秒的测试中，大约60秒后达到最大摄氧量。得出的结论是，30秒和90秒测试并非严格意义上的无氧测试，尽管它们都有很大的无氧成分。
