“Each subject performed an incremental exercise test to
exhaustion on an electronically braked cycle ergometer
(ERGOLINE 900, Hellige, Markett, Bitz, Germany). The
VO2max test was used to determine VO2max, the minimal
power that elicited VO2max (PVOmax), and the power
associated with the lactate threshold (pLT), The lactate
threshold was determined from the relationship between
blood lactate concentration and power output and was
defined as a non-linear increase in the lactate concentration
of at least 1 mM (3) (Table 2). The test began at 50 W for
6 min and increased 50 W every 3 min until exhaustion.”
