Blood was collected prior to, after ingestion of sodium citrate (NaHCO3), and postexercise, from a heated (43-46°C) fingertip and analysed immediately postcollection for pH, partial pressure of oxygen and carbon dioxide, base excess and blood bicarbonate. Total work undertaken (kJ) and peak power (W) achieved during the tests was also obtained via a work monitor unit. The results indicated that a dose of 0.5 g sdkg−1 body mass sodium citrate had no ergogenic benefit for exercise of either 10-s or 30-s duration. Blood bicarbonate concentrations, however, were significantly increased (P<0.05) following ingestion of the citrate during these trials. Exercise periods of 120 s and 240 s were significantly increased (P<0.05) above the control and placebo conditions following sodium citrate ingestion. Blood bicarbonate concentrations were again increased above control and placebo conditions and blood lactate concentrations were also increased following the citrate trials. The pH decreased significantly (P<0.05) in all trials below the control and placebo conditions. On the basis of the exercise undertaken in this study we would suggest that a dose of 0.5 g·kg−1 body mass of sodium citrate could improve anaerobic exercise performance of 120-s and 240-s duration.
