Does running reduce muscle?

Running is a very good aerobic exercise. It can effectively help us promote the consumption of calories in the body. It can also greatly improve our cardiopulmonary breathing difficulties. It can effectively help us shape a slim and healthy body. Running helps to shape muscles. I believe everyone is very interested in the question of whether running can reduce muscle.

Fast running (anaerobic exercise) cannot reduce muscle, but long-distance running (aerobic exercise) can.

Although aerobic exercise is an effective way to burn fat, long-term aerobic exercise consumes not only fat but also muscle.

Exercise physiologists have found that when exercise reaches 60% of the maximum heart rate, the body consumes more fat than sugar (glycogen) or protein (muscle). But if the exercise intensity is higher, that is, above 75% of the maximum heart rate, the body will directly use fat, sugar and protein as energy sources. In other words, the harder you train, the more calories you burn.

Aerobic exercise can burn calories, but it cannot increase your metabolic rate for a long time. Although strength training cannot increase your heart rate for a long time, it can effectively increase the body's metabolic rate when it is at rest, and you can burn more fat even if you sit still. Moreover, after you finish strength training, your body will usher in a peak of metabolism: the internal circulation will run at a high speed and will last for two hours. You can also burn more calories while resting. That's why combining aerobic exercise with strength training is the best way to lose weight.

The answer to the question "Does running reduce muscle mass?" is no. Not only does running not reduce muscle mass, it may also increase muscle mass. It may increase our calf muscles, make our bones stronger, and enhance bone toughness and strength. At the same time, running can also improve our own physical health.
