Acidosis, but Not Alkalosis, Affects Anaerobic Metabolism and Performance in a 4-km Time Trial

ABSTRACTPurposeThis study aimed to determine the effect of preexercise metabolic acidosis and alkalosis on power output (PO) and aerobic and anaerobic energy expenditure during a 4-km cycling time trial (TT).MethodsEleven recreationally trained cyclists (V˙O2peak 54.1 ± 9.3 mL·kg−1·min−1) performed
