Physiology and energy systems

Sports Physiology is how the human body adapts to exercise. For the body to perform in sport there are a number of energy systems

• the alactic anaerobic system is used by 100m sprinters, producing explosive, short duration, high intensity movements using energy already in the muscles
•  the lactic anaerobic system is used by 400m runners, producing sustained, high intensity movement
• the aerobic system is used by distance runners, energy demands are lower but it is sustained longer
