Six men performed a total of 23 modified Wingate power tests against 5.5 kp (53.9 N) resistance on a Monark 864 ergometer. Breath-by-breath VO2 was measured using a SensorMedics 4400 metabolic cart. Peak anaerobic power (highest 5 s; mean(s.e.m.)) was 819(16) W (11.1(0.6) W kg-1) and anaerobic capacity (work in 30 s; mean(s.e.m.)) was 18.2(0.2) kJ (248(11) J kg-1). Contributions of ATP-PC, glycolytic and aerobic systems each 5 s were estimated. ATP-PC power (mean(s.e.m.)) peaked at 750(14) W (10.2(0.6) W kg-1) in the first 5 s; glycolytic power (mean(s.e.m.] peaked at 497(11) W (6.8(0.7) W kg-1) between 10 and 15 s into the test; aerobic power (mean(s.e.m.)) peaked at 157(5) W (2.1(0.3) W kg-1) during the last 5 s of the test, and VO2 exceeded 90% VO2peak Over the entire 30 s, aerobic contribution was 16%, glycolytic contribution was 56%, and ATP-PC contribution was 28%. It is concluded that glycolytic power peaks within the first 15 s of high power exercise; also, aerobic metabolism responds quickly during 'anaerobic' exercise and makes a significant contribution to the work performed.
六名男性在Monark 864型测力计上针对5.5千帕（53.9牛顿）的阻力总共进行了23次改良的温盖特功率测试。使用SensorMedics 4400型代谢分析仪逐次呼吸测量耗氧量（VO₂）。峰值无氧功率（最高5秒；平均值（标准误））为819（16）瓦（11.1（0.6）瓦/千克），无氧能力（30秒内的功；平均值（标准误））为18.2（0.2）千焦（248（11）焦/千克）。估计了三磷酸腺苷-磷酸肌酸（ATP-PC）、糖酵解和有氧系统每5秒的贡献。ATP-PC功率（平均值（标准误））在最初5秒达到峰值750（14）瓦（10.2（0.6）瓦/千克）；糖酵解功率（平均值（标准误））在测试进行到10至15秒之间达到峰值497（11）瓦（6.8（0.7）瓦/千克）；有氧功率（平均值（标准误））在测试的最后5秒达到峰值157（5）瓦（2.1（0.3）瓦/千克），并且在整个30秒内耗氧量超过了最大摄氧量（VO₂peak）的90%。有氧贡献为16%，糖酵解贡献为56%，ATP-PC贡献为28%。结论是，糖酵解功率在高强度运动的前15秒内达到峰值；此外，有氧代谢在“无氧”运动期间反应迅速，并对所完成的工作做出了重大贡献。
