Performance and metabolic profiles of the Wingate Anaerobic Test (WAnT) were compared between a mechanically resisted (ME) and an electro-magnetically braked (EE) cycle ergometer. Fifteen healthy subjects (24.0+/-3.5 years, 180.5+/-6.1 cm, 75.4+/-11.9 kg) performed a WAnT on ME, and EE 3 days apart. Performance was measured as peak power (PP), minimum power (MP), mean power (AP), time to PP (TTPP), fatigue rate (FR), and maximum cadence (RPM(MAX)). Lactic (W (LAC)) and alactic (W (PCR)) anaerobic energy were calculated from net lactate appearance and the fast component of post-exercise oxygen uptake. Aerobic metabolism (W (AER)) was calculated from oxygen uptake during the WAnT. Total energy cost (W (TOT)) was calculated as the sum of W (LAC), W (PCR), and W (AER). There was no difference between ME and EE in PP (873+/-159 vs. 931+/-193 W) or AP (633+/-89 vs. 630+/-89 W). In the EE condition TTPP (2.3+/-0.7 vs. 4.3+/-0.7 s) was longer (P<0.001), MP (464+/-78 vs. 388+/-57 W) was lower (P<0.001), FR (15.2+/-5.2 vs. 20.5+/-6.8%) was higher (P<0.005), and RPM(MAX) (168+/-18 vs. 128+/-15 rpm) was slower (P<0.001). There was no difference in W (TOT) (1,331+/-182 vs. 1,373+/-120 J kg(-1)), W (AER) (292+/-76 vs. 309+/-72 J kg(-1)), W (PCR) (495+/-153 vs. 515+/-111 J kg(-1)) or W (LAC) (545+/-132 vs. 549+/-141 J kg(-1)) between ME and EE devices. The EE produces distinctly different performance measures but valid metabolic WAnT results that may be used to evaluate anaerobic fitness.
比较了机械阻力（ME）和电磁制动（EE）两种功率自行车上进行的温盖特无氧测试（WAnT）的运动表现和代谢特征。15名健康受试者（年龄24.0±3.5岁，身高180.5±6.1厘米，体重75.4±11.9千克）分别在ME和EE功率自行车上进行WAnT测试，测试间隔3天。运动表现指标包括峰值功率（PP）、最低功率（MP）、平均功率（AP）、达到PP的时间（TTPP）、疲劳率（FR）和最大踏频（RPM(MAX)）。乳酸（W (LAC)）和非乳酸（W (PCR)）无氧能量通过净乳酸生成量和运动后摄氧量的快速成分计算得出。有氧代谢（W (AER)）通过WAnT测试期间的摄氧量计算得出。总能量消耗（W (TOT)）计算为W (LAC)、W (PCR)和W (AER)之和。ME和EE在PP（873±159瓦对931±193瓦）或AP（633±89瓦对630±89瓦）方面无差异。在EE条件下，TTPP（2.3±0.7秒对4.3±0.7秒）更长（P<0.001），MP（464±78瓦对388±57瓦）更低（P<0.001），FR（15.2±5.2%对20.5±6.8%）更高（P<0.005），RPM(MAX)（168±18转/分钟对128±15转/分钟）更慢（P<0.001）。ME和EE设备在W (TOT)（1331±182焦耳/千克对1373±120焦耳/千克）、W (AER)（292±76焦耳/千克对309±72焦耳/千克）、W (PCR)（495±153焦耳/千克对515±111焦耳/千克）或W (LAC)（545±132焦耳/千克对549±141焦耳/千克）方面无差异。EE产生明显不同的运动表现指标，但能得出有效的代谢WAnT结果，可用于评估无氧适能。
