What are the dangers of aerobic exercise?

Aerobic exercise is now known as the healthiest exercise. It does not require a lot of physical energy, but it can exercise your body. However, some people worry that exercise will always have some side effects and harms. In fact, aerobic exercise does not have any harm. It’s just that if the exercise is not done properly, there will be some side effects. The following editor will introduce to you some of the dangers of incorrect aerobic exercise. I hope this helps you all.

Myth: Aerobic exercise is better than strength training for controlling body fat.

Fact: Combining aerobic exercise with strength training is the best way to keep body fat at an ideal level. Many people mistakenly believe that aerobic exercise alone is most effective for controlling and reducing body fat for two reasons. ⑦ Aerobic exercise first consumes fat, while strength training consumes sugar stored in the body: ② Within the set heart rate range, 45 minutes of aerobic exercise consumes more calories than strength training of the same duration. Strength training, which requires rest between each set, consumes much fewer calories.

Indeed, during aerobic exercise, the body consumes stored body fat as fuel; in fact, glycogen in the body (in the blood, muscles and liver) is also consumed at the same time. Studies show that during the first 20 minutes of moderate-intensity aerobic exercise. (reaching an intensity of 65% of the maximum heart rate), most of the body consumes glycogen. Yes, 45 minutes of aerobic exercise burns more calories than the same amount of strength training (at the same intensity). However, those who have increased their muscle mass will have a higher resting metabolic rate, so even when they are resting, the calories they consume in a day will also increase significantly. It is estimated that for every 0.5 kg of muscle gained, the body can consume an additional 50 to 100 kcal of calories per day. For a person who has gained 5 kilograms of muscle, this means burning 500-1000 kcal more per day, or 3500-7000 kcal more per week.

The reason is this: aerobic exercise can achieve the purpose of burning calories, but it cannot increase the metabolic rate for a long time. Although strength training cannot increase heart rate for a long time, it increases the total muscle mass, thereby increasing the metabolic rate and allowing people to consume more calories even when resting. That's why combining aerobic exercise with strength training is the best way to lose weight.

Exercise has been considered a healthy lifestyle since ancient times, but if you exercise improperly, it will not only be of no help to your body, but will also cause harm to your body. I hope the above article can bring you benefits.
