Why does cardio/aerobic exercise lead to muscle loss?

3 min read

Asked by: Moustache Guitars

This is mostly because of the nutritional requirements of those sports; you are in the aerobic zone for a long time and burning lots of calories, and some of those will come from protein. Also, after the exercise is over, your body will want to rebuild carbohydrate stores and it may tear down muscle mass to get there.

Does aerobic exercise cause muscle loss?

The current paradigm in skeletal muscle biology and exercise physiology is that aerobic exercise has a negligible effect on skeletal muscle mass.

Why does cardio make you lose muscle?

The main reason fasted cardio can cause muscle loss is that it quickly depletes muscle glycogen levels, and when this happens, the body begins to break down protein (muscle) for energy. However, you generally have to do a fair amount of cardio—at least 60 minutes or more—to deplete glycogen levels.

How does aerobic exercise affect muscles?

By changing the composition of muscle fibers, aerobic workouts increase endurance. Aerobic exercise promotes recovery and repair of muscles after workouts, which in turn assists with muscle growth. Increased myoglobin and mitochondria in muscle tissue triggered by aerobic workouts promotes greater aerobic ability.

Does cardio ruin gains?

Too much cardio can interfere with muscle growth—but so can too little. Performing cardio 2-3 days a week seems to be the sweet spot for complementing your training gains without putting your muscle at risk.

Does cardio remove muscle?

Yes, cardio can burn muscle but only if you’re not doing enough weight training or supplementing your workouts with a nutritious diet. Cardio doesn’t automatically burn your muscle. But it can burn muscle if you (1) do it too much, (2) do it before your weight training session, or (3) do ‘high impact’ cardio.

How do I do cardio without losing muscle?

Should I do cardio if I want to gain muscle?

Does HIIT make you lose muscle?

HIIT may not be the most effective workout routine to build lean muscle mass. HIIT, however, can help preserve or retain lean muscle mass, while MICT can potentially make you lose lean muscle mass if you’re trying to lose fat mass at the same time.
