In a counterbalanced, crossover design, nine healthy and active males (age: 23±2 years, height: 179±5 cm, body mass: 74±9 kg, peak mean minute power (WPEAK) 256±45 W, peak oxygen uptake (V̇O2PEAK) 46±8 ml.kg(-1).min(-1)) performed a graded incremental exercise test, two familiarisation and two experimental trials. Experimental trials consisted of cycling to volitional exhaustion (TLIM1) at 100% WPEAK on two occasions (TLIM1 and TLIM2) interspersed by a 90 min passive recovery period. Using a double blind approach, 30 min into a 90 min recovery period participants ingested either 0.3 g.kg(-1) body mass sodium bicarbonate (NaHCO3) or a placebo (PLA) containing 0.1 g.kg(-1) body mass sodium chloride (NaCl) mixed with 4 ml.kg(-1) tap water and 1 ml.kg(-1) orange squash. The mean differences between TLIM2 and TLIM...
