AB  - Seven healthy male subjects exercised to exhaustion at a workload equivalent to 
      100% of their maximal oxygen uptake (VO2max) on 3 separate occasions. Each high 
      intensity exercise test was performed on an electrically braked cycle ergometer; 
      the first took place after a normal diet (46 +/- 8% carbohydrate (CHO), 41 +/- 7% 
      fat and 13 +/- 3% protein); the second after 3 days of a low CHO diet (7 +/- 3% 
      CHO, 64 +/- 5% fat and 29 +/- 4% protein) and the third after 3 days of a high 
      CHO diet (76 +/- 6% CHO, 14 +/- 5% fat and 10 +/- 2% protein). Acid-base status 
      and selected metabolites were measured on arterialized venous blood at rest prior 
      to exercise and during the post-exercise period. Plasma urea concentration and 
      urine total acidity were measured on each day of the experiment. Exercise time to 
      exhaustion was longer after the normal (p less than 0.05) and high (p less than 
      0.01) CHO diets compared with the low CHO diet. Pre-exercise plasma bicarbonate 
      concentration and blood PCO2 were higher after the high CHO diet when compared 
      with the normal (p = 0.05, p less than 0.05 respectively) and low CHO conditions 
      (p less than 0.05, p less than 0.05 respectively). Pre-exercise bicarbonate was 
      also higher after the normal CHO diet when compared with the low CHO diet (p less 
      than 0.05).(ABSTRACT TRUNCATED AT 250 WORDS)
