AIM: The aim of the present study was to measure and compare the aerobic, anaerobic alactic and anaerobic lactic energy system contribution during the 30-Âsec Wingate anaerobic test (WAnT) for the upper and lower body within the same individuals. METHODS: Physically active men (n=14) completed two WAnTs on an electronic arm ergometer and a cycle ergometer separated by three days. A fly wheel braking force corresponding to 5% and 7.5% of the participants body weight was used for the upper and lower body WAnTs respectively. Oxygen uptake and blood lactate were measured before, during and after both WAnTs, and body composition was measured using dual-Âenergy X-Âray absorptiometry (DEXA). RESULTS: The anaerobic lactic energy system contribution was significantly ( p < 0.01) higher during the upper body (60.3±5.6%) compared to the lower body (46.9±6.9%) WAnT. The contribution of the anaerobic alactic system was significantly higher ( p < 0.01) during the lower body (36.5±6.3%) compared to the upper body (28.3±4.9%) WAnT, with the aerobic system contribution significantly ( p < 0.05) higher for the lower body (16.8±2.5%) compared to the upper body (11.4±1.4%) WAnT. CONCLUSIONS: The anaerobic lactic energy system provides over 60% of the energy requirements during an upper body WAnT but provides less the 50% during the lower body WAnT. In contrast, the aerobic and anaerobic alactic energy system contribution was significantly less for the upper body WAnT compared to the lower body WAnT.
