AB  - The effect of a pattern of exercise and dietary modifications, which was designed 
      to produce alterations in the muscle glycogen content, on the capacity to perform 
      anaerobic exercise was investigated. Six young male subjects worked to exhaustion 
      on a bicycle ergometer at a supramaximal work load equivalent to 104 +/- 5% of 
      VO2max after a normal diet, after a carbohydrate (CHO)-free diet following 
      prolonged exhausting exercise, and after a high-CHO diet. This regimen has 
      previously been shown to cause changes in the glycogen content of the working 
      muscle. Mean work time for subjects on the first test was 4.87 +/- 1.07 min (mean 
      +/- SD). After the low-CHO diet, the time for which work could be maintained was 
      reduced in an increase to 3.32 +/- 0.93 min, whereas administration of the 
      high-CHO diet resulted in an increase to 6.65 +/- 1.39 min. The resting blood 
      lactate concentration was lower than normal following the low-CHO diet and higher 
      than normal following the high-CHO diet. Post exercise blood lactate 
      concentrations reached a peak between 2 and 6 min after exhaustion and again were 
      lower (8.60 +/- 1.58 mmol/l) after the low-CHO diet and higher (12.86 +/- 1.42 
      mmol/l) after the high-CHO diet than after performing the same intensity of work 
      to exhaustion on a normal diet (11.66 +/- 1.16 mmol/l). The rate of lactate 
      accumulation appeared to be approximately the same during exercise under all 
      three dietary conditions. If this is the case, it suggests that the alterations 
      in endurance capacity do not result from changes in the rate of anaerobic 
      glycolytic energy production, but possibly from a change in the total capacity of 
      the system.
