Table 2. Mountain bike competition (COMP): Data represent racing time (RT
COMP), power output (PO
COMP), cadence, oxygen uptake (VO
2COMP), heart rate (HR
COMP), pulmonary ventilation (VE
COMP), respiratory exchange ratio (RER
COMP) and blood lactate concentration (BLa
COMP) and are depicted for the entire COMP and for every lap. Values are (means ± SD) for all subjects (n = 24) and for a high performance athlete (HPA).
