  1. Fatigue: Perceived effort and inability to produce force or power.
  2. Central Fatigue: Alteration of Central Nervous System function that can't be explained by dysfunction in the muscle.
  3. Central Fatigue Hypothesis: Links plasma amino acids to serotonergic system. In other words. . .high levels of serotonin have been associated with feelings of lethargy and fatigue.
  4. Her study:
    1. "Would hydration alter perceived fatigue in elite athletes?".
    2. Elite athletes were measured (blood draws) while hydration with Branched Chain Amino Acid (BCAA) drinks were administered during exercise.
    3. Athletes were measured in time to perceived fatigue.
  5. Her results:
    1. BCAA drinks DID delay the onset of perceived fatigue.
    2. BCAA drinks also had a negative effect on plasma ammonia development.
    3. BCAA drinks have a positive effect on fatigue response, but it is offset by dangers in ammonia production.
  6. Her recommendations:
    1. Carbohydrate replacement drinks (CHO) provide the same delay of the onset of the perceived fatigue response but without the problems of ammonia production.
    2. Carbohydrate replacement drinks help the athlete to delay the onset of fatigue and perceived fatigue responses.
