Eleven recreational sportsmen (age: 22±1years, height: 175±6cm, weight: 71±5kg) volunteered to participate in the study. For each subject the first and second ventilatory thresholds (VT1 and VT2, respectively) and the power output corresponding to (respiratory exchange ratio) RER=1.00 were determined during an incremental test to exhaustion. Thereafter, each subject performed several 30-min constant load tests to determine MLSS. The workload used in the first constant test was set to the ẆRER=1.00 determined during the incremental test. ẆVT1 (175±24W) and ẆVT2 (265±31W) were significantly different from ẆMLSS (220±36W). Whereas, ẆRER=1.00 (224±33W) was similar to ẆMLSS. HR, RER and V̇E were significantly different between the 10th and the 30th minutes when exercising at ẆRER=1.00 and at ẆMLSS. In contrast, V̇O2 and V̇CO2 were stable over those 30-min constant tests. Power output at VT1, RER=1.00 and VT2 were all correlated to ẆMLSS but the relationship was stronger between RER=1.00 and MLSS (R 2=0.95). The present study shows that the power output associated with a RER value equal to 1.00 during an incremental test does not differ from that determined for MLSS. Hence, the MLSS can be estimated with a single exercise test.
