Does your body vary the utilization of nutrients depending on the type of physical activity?
Depending on the type of physical activity, sport and stress different muscle fibers and energy sources are used.
In general we can say that:
- In rest conditions 87% of energy comes from fat and 13% from the sugars.
- During an exercise of medium intensity and / or medium duration the energy is supplied for the 50% from fats and 50% from sugars
- During a very high intensity exercise and short duration the energy is supplied almost entirely from glycogen (approximately 100%)
- During prolonged exercise and high intensity 70% of the energy comes from fat and 30% from the sugars.
