Abstrakt: Background Belt electrode skeletal muscle stimulation (B-SES) is an alternative exercise therapy for those with difficulty performing voluntary exercise. However, it is unknown whether oxygen uptake (VO 2 ) in B-SES is comparable to cardiopulmonary exercise test (CPX) as assessed by voluntary exercise. This study aimed to evaluate oxygen uptake (VO 2 ) and lactate (LA) production in incremental B-SES compared to ergometer CPX and to determine the relationship with ergometer CPX. Methods This study included 10 healthy young Japanese participants. Using a crossover design, all participants underwent incremental B-SES CPX and ergometer CPX using a 20 W ramp. Serum lactic acid concentration (LA) was measured serially before, during, and after B-SES. The tolerability of B-SES was adjusted with the change in LA level (⊿LA). Results Peak VO 2 during B-SES (14.1±3.3 mL/kg/min) was significantly lower than ergometer peak VO 2 (30.2±6.2 mL/kg/min, P<0.001). B-SES peak VO 2 was similar to the anaerobic threshold (AT) VO 2 on ergometer CPX (15.1±2.6 mL/kg/min). LA (Rest: 1.4±0.3, Peak: 2.8±0.8 mmol) and plasma noradrenalin (Rest: 0.2±0.1, Peak: 0.4±0.1 ng/mL) levels increased after B-SES. No significant correlation was observed between B-SES peak VO 2 and ergometer CPX. However, after adjusting for B-SES, tolerability, it (peak VO 2 of B-SES /⊿LA) correlated with peak VO 2 (r=0.688, p=0.028) on the ergometer. Conclusion Peak VO 2 of the passively progressive B-SES almost reached the AT value of the ergometer CPX without adverse events. Peak VO 2 of B-SES adjusted with ⊿LA may be used to predict peak VO 2 in ergometer CPX.
