... ATP, CP and glycogen, increased enzyme activity improving the efficiency of the ATP-PC and lactic acid systems, increased tolerance to high levels of lactic acid and a more efficient removal system during recovery and a delay in the thresholds of the ATP-PC and lactic acid systems, which means that trained performer is able to generate more ATP and work at a high intensity rate for a longer period of time. These adaptations are just some of the advantages that a trained athlete has over their untrained peers, for example, in sprint races the athlete will be able to run faster, in long distance events the athlete will be ale to run at a higher intensity for a longer period of time and in weight lifting the trained athlete will be able to lift heavier weights. The next category that trained athletes have an advantage in compared to untrained athletes is the ...
