Greater activities of the enzymes of the phosphagen system
More CP and ATP in muscle
Explanation:
During high intensity exercises the large amount of muscle energy is required. This creates a high demand of ATP. The phosphagen system is the quickest method to resynthesize ATP. The creatine phosphate in the absence of oxygen provides phosphate to produce ATP. This provides greater mitochondrial power, in the rest the CP and ATP remain stored in the muscles. The enzymatic activity enhances with the phosphagen system.
