       Chapter 2 Introduction
   • Carbohydrate as a Fuel for Exercise:
    – Well-documented that CHO is important for athletic 
     performance
    – High levels of stored glycogen before endurance 
     exercise (esp. > 1hr) can help increase performance 
     & reduce time to fatigue
    – High CHO post-exercise enhances recovery
    – Many athletes consume inadequate levels of CHO to 
     support their training
          Dietary Carbohydrate
   • Optimum dietary CHO levels depend on:
     – Total energy intake
     – Body size
     – Health status
     – Duration, intensity, frequency, 
       and type of exercise 
  Function, Classification, 
   and Dietary Sources 
    of Carbohydrate
        Function of Carbohydrates
   • CHO are:
     – Primary source of energy (1 of 3 macronutrients)
     – Provide the substrate necessary for glycogen 
      replacement (substrate: glucose)
     – When consumed during exercise, help maintain BG 
      levels & help prevent premature fatigue
   • CHO recommendations for active individuals:
     – Moderate training: 5-7 g/kg of BW
     – Heavy training: up to 10 g/kg of BW (Burke, 2007)
     Classification of Dietary CHO
   • Different ways to classify CHO
    – Type of CHO found in the food
    – Level of commercial processing the food has 
     undergone
    – BG or glycemic response to the CHO within the 
     body
