TI  - Pre-exercise nutritional strategies: effects on metabolism and performance.
PG  - S64-70
AB  - The goals of pre-exercise nutritional strategies are to optimise the availability 
      of carbohydrate (CHO) and fluid. Ingestion of CHO 3-4 hr prior to exercise can 
      increase liver and muscle glycogen stores and has been associated with enhanced 
      endurance exercise performance. The metabolic effects of CHO ingestion persist 
      for at least 6 hr. Although an increase in plasma insulin following CHO ingestion 
      in the hour prior to exercise inhibits lipolysis and liver glucose output, and 
      can lead to transient hypoglycemia during subsequent exercise, there is no 
      convincing evidence that this is always associated with impaired exercise 
      performance. Having said that, individual experience should inform individual 
      practice. Interventions to increase plasma FFA availability prior to exercise 
      have been shown to reduce CHO utilisation during exercise, but do not appear to 
      have major ergogenic benefits. It is more difficult to hyperhydrate prior to 
      exercise and although there has been interest in glycerol ingestion, to date 
      research results have been equivocal. At the very least, athletes should ensure 
      euhydration prior to exercise.
