Why do people lose weight after a period of fitness?
Aerobic metabolic exercise, also known as aerobic exercise, refers to the process in which sugar and fat in the human body release energy for the synthesis of ATP (adenosine triphosphate) and CP (creatine phosphate) and release energy for muscle needs under the condition of adequate oxygen supply during fitness. Therefore, the purpose of losing weight is achieved by consuming sugar and fat in the body through aerobic exercise. Generally, the exercise with low load intensity, many times and slow speed mainly depends on aerobic metabolism for energy supply. Typical aerobic exercise includes walking, running, cycling or dumbbell exercise with low load and many times. During the whole exercise, the oxygen inhaled by the human body is roughly equivalent to the required amount. Aerobic metabolic exercise can effectively improve the function of human cardiovascular system.
