Key result
Preexercise metabolic alkalosis via NaHCO3 ingestion significantly reduced oxygen uptake kinetics (tau1) by 7.9 ± 2.6 s during high-power-output exercise compared with control (P=0.011).
Why the study?
Does preexercise metabolic alkalosis induced via bicarbonate ingestion accelerate VO2 kinetics at the onset of high-power-output exercise in healthy men?
Population
7 healthy physically active nonsmoking men, mean age 22.4 +/- 1.8 years, maximum VO2 50.4 +/- 4 ml.min.kg
Comparison

p-value: p=0.011
Preexercise metabolic alkalosis induced by sodium bicarbonate ingestion significantly accelerates VO2 kinetics during high-intensity exercise in healthy men.
Żołądź et al. (2004) studied Healthy physically active nonsmoking men (n=7). NaHCO3 (sodium bicarbonate) vs. Control study was evaluated on Primary component of oxygen uptake (Vo2) kinetics (tau1) during cycling at 87% of Vo2 max (reduction of 7.9 s, p=0.011). Preexercise metabolic alkalosis via NaHCO3 ingestion significantly reduced oxygen uptake kinetics (tau1) by 7.9 ± 2.6 s during high-power-output exercise compared with control (P=0.011).
