Anaerobic and aerobic metabolism

Anaerobic metabolism and aerobic metabolism (anaerobic respiration and aerobic respiration) are the two methods of generating energy in the human body, including converting food sources into energy for exercise, mental activity and physical activity.

Aerobic respiration


Aerobic respiration is also known as cellular respiration.

Anaerobic exercise
Anaerobic exercise is high-intensity exercise that is meant to be very short (10 to 15 seconds) and fast/powerful, and usually can't be sustained for long. Typically the exercise is then repeated after a short rest. The word "anaerobic" means without oxygen, instead of using oxygen to keep muscles going, the energy already stored in the muscles is used, known as glycogen.



Examples include:
 * Resistance training, like using gym machines with weights
 * Very short sprints
 * Weight lifting

Aerobic exercise
Aerobic exercise is "cardiovascular conditioning ("cardio") that strengthens both your heart and lungs, using continuous movements. The word aerobic means "with oxygen," aerobic exercise is fueled by the oxygen from breathing, which means it can be carried out for an extended period of time.

Examples include:
 * Running or jogging
 * Walking at a brisk pace
 * Swimming
 * Rowing
 * Cycling
 * Step aerobics or aqua aerobics
 * Using cardio machines like an elliptical or stair climber
