Twenty-three subjects participated in the investigation (8 females and 15 males, age 21.4 +/- 2.3, mean +/- sd). Subjects completed six trials; three following the ingestion of sodium bicarbonate (300 mg/kg body weight) and three following the ingestion of a placebo (8 g sodium chloride). Each trial consisted of ten ten-second sprints on a cycle ergometer with 50 seconds recovery between each sprint. {\textquoteright}Peak power{\textquoteright} and {\textquoteright}average power output{\textquoteright} during each ten second sprint was measured from the flywheel of the ergometer using a light-sensitive monitor (Cranlea) linked to a BBC microcomputer. The power outputs recorded during each ten-second sprint of the bicarbonate trials were then compared with those recorded during the corresponding sprint of the placebo trials. The bicarbonate trials produced higher mean {\textquoteright}average power{\textquoteright} outputs in all ten of the ten-second sprints, with the difference in {\textquoteright}average power{\textquoteright} output being statistically significant in eight of these (p less than 0.05). The results also revealed that the difference in the {\textquoteright}average power{\textquoteright} outputs attained during the bicarbonate and placebo trials increased as the number of sprint repetitions increased (p less than 0.01). {\textquoteright}Peak power{\textquoteright} output was also greater in the bicarbonate trials with it being significantly higher (p less than 0.001) during the final ten-second sprint. It was concluded that during exercise consisting of repeated, short-duration sprints, power output was enhanced following the ingestion of sodium bicarbonate, (300 mg/kg body weight).}, issn = {0306-3674}, URL = {https://bjsm.bmj.com/content/23/1/41}, eprint = {https://bjsm.bmj.com/content/23/1/41.full.pdf}, journal = {British Journal of Sports Medicine} }
