AB  - This study examined the effects of dietary manipulation upon the respiratory 
      exchange ratio (R = VCO2/VO2) as a predictor of maximum oxygen uptake (VO2max). 
      Seven healthy males performed fixed term maximal incremental treadmill exercise 
      after an overnight fast on three separate occasions. The first test took place 
      after the subjects had consumed their normal mixed diet (45 +/- 5% carbohydrate 
      (CHO] for a period of three days. This test protocol was then repeated after 
      three days of a low CHO diet (3 +/- 2% CHO), and again after three days of a high 
      CHO diet (61 +/- 5% CHO). Respiratory gases were continuously monitored during 
      each test using an on-line system. No significant changes in mean exercise oxygen 
      uptake (VO2), VO2max or maximum functional heart rate (FHRmax) were found between 
      tests. Mean exercise carbon dioxide output (VCO2) and R were significantly lower 
      than normal after the low CHO diet (both p less than 0.001) and significantly 
      higher than normal after the high CHO diet (both p less than 0.05). Moreover, 
      compared with the normal CHO diet, the R-time relationship during exercise was at 
      all times significantly (p less than 0.001) shifted to the right after the low 
      CHO diet, and shifted to the left, being significantly so (p less than 0.05) over 
      the final 5 min of exercise, after the high CHO diet.(ABSTRACT TRUNCATED AT 250
