Table 1 The basic characteristics of the three energy supply systems
Name of energy supply system | Energy substrate | Available exercise time | Supply substances and metabolites for ATP recovery |
|---|---|---|---|
ATP-CP | ATP | 6 ~ 8 s | CP |
CP | < 10s | CP + ADP → ATP + C | |
Glycolytic system | Glucose | 2 ~ 3 min | Glucose → Lactic acid |
Oxidative system | Glucose | 3 ~ 5 min | Glucose → CO2 + H2O |
Fat | 1 ~ 2 h | Fat → CO2 + H2O |
