dc.description.abstract Objective: To determine the effects of electrical stimulation (ES) on oxygen uptake (Vo2) kinetics and delta efficiency (DE) during gradual exercise. The hypothesis was that ES would attenuate the Vo2-workload relation and improve DE. Methods: Fifteen healthy, untrained men (mean (SD) age 22 (5) years) were selected. Ten were electrostimulated on both quadriceps muscles with a frequency of 45-60 Hz, with 12 seconds of stimulation followed by eight seconds recovery for a total of 30 minutes a day, three days a week for six weeks. The remaining five subjects were assigned to a control group. A standardised exercise test on a cycle ergometer (ramp protocol, workload increases of 20 W/min) was performed by each subject before and after the experimental period. The slope of the Vo2-power output (W) relation (ΔVo2/ΔW) and DE were calculated in each subject at moderate to high intensities (above the ventilatory threshold - that is, from 50-60% to 100% Vo2max). Results: The mean (SEM) values for ΔVo2/ΔW and DE had significantly decreased and increased respectively after the six week ES programme (p<0.05; 9.8 (0.2) v 8.6 (0.5) ml O2/W/min respectively and 27.7 (0.9) v 31.5 (1.4)% respectively). Conclusions: ES could be used as a supplementary tool to improve two of the main determinants of endurance capacity, namely Vo2 kinetics and work efficiency. spa
