Mechanically versus electro-magnetically braked cycle ergometer: performance and energy cost of the Wingate Anaerobic Test.

摘要: Performance and metabolic profiles of the Wingate Anaerobic Test (WAnT) were compared between a mechanically resisted (ME) 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 WAnT on ME, EE 3 days apart. was measured as peak power (PP), minimum (MP), mean (AP), time to PP (TTPP), fatigue rate (FR), maximum cadence (RPMMAX). Lactic (WLAC) alactic (WPCR) anaerobic energy calculated from net lactate appearance fast component post-exercise oxygen uptake. Aerobic metabolism (WAER) uptake during WAnT. Total cost (WTOT) sum WLAC, WPCR, WAER. There no difference ME in (873±159 vs. 931±193 W) or AP (633±89 630±89 W). In condition TTPP (2.3±0.7 4.3±0.7 s) longer (P<0.001), MP (464±78 388±57 lower FR (15.2±5.2 20.5±6.8%) higher (P<0.005), RPMMAX (168±18 128±15 rpm) slower (P<0.001). WTOT (1,331±182 1,373±120 J kg−1), WAER (292±76 309±72 WPCR (495±153 515±111 kg−1) WLAC (545±132 549±141 devices. The produces distinctly different performance measures but valid results that may be used evaluate fitness.
