We already know that fat will decompose as an energy source; However, the body also breaks down protein and carbohydrates. When the body lacks energy, the insulin content will be very low. At this time, the body will secrete other hormones (glucagon), so that the tissues of the whole body begin to decompose and produce usable energy. Therefore, long-term low insulin and high glucagon in the body are unfavorable for muscle gain. Adding protein to the diet can slow down the loss of muscle tissue, but it can't completely stop the loss. It is generally believed that when the body lacks energy seriously, it will consume the tissues in the body to provide energy.

2. Heart rate response to aerobic exercise

This is the most direct index to measure the effect and intensity of aerobic exercise. Many fitness equipment in the gym have calorie counts. But in fact, this calculation is quite different from the actual consumption, and there is no constant ratio between calorie consumption and fat consumption. The catabolism of fat is a series of complex biochemical reactions. Heart rate reflects the excitement of sympathetic nerve and promotes the secretion of a series of lipolytic hormones.

3. The fat-reducing reaction of aerobic exercise

Aerobic exercise and strength training have the same fitness effect. The difference is that aerobic exercise consumes fat first, while strength training consumes sugar in the body first. At the same time, aerobic exercise consumes more calories than strength training. Even so, it cannot be said that aerobic exercise is better than strength training. The best way to eliminate fat should be the combination of aerobic exercise and strength training. Moreover, strength training can improve metabolism in the body more than aerobic exercise, and can help burn calories even at rest.

Sticking to aerobic exercise can cure fatty liver.

1, the increase of liver lipid content will increase the risk of metabolic complications. Although long-term exercise can reduce liver lipid content, whether short-term acute exercise has the same effect has not been studied. The atp content in liver may be related to insulin resistance and the increase of liver lipid content. The researchers explored whether acute exercise will affect the liver lipid content and whether it is accompanied by changes in the liver atp content. They selected 2 1 male (age 54. 8 7。 2 years old, bmi29. 72。 2kg/m2) for two hours, one experiment was conducted on an empty stomach and the other experiment was conducted with glucose intake.

2. The researchers observed that the liver fat of each exercise group had obvious changes. In the high-intensity and low-volume aerobic exercise (HI: LO) group, the liver fat decreased by 2. 38%, in the low-intensity and high aerobic exercise (LO: HI) group, the liver fat decreased by 2. 62%, in the group of low intensity and low aerobic exercise (LO: LO), the liver fat decreased by 0. 84%, while the placebo group increased 1. 1%。

Aerobic exercise suitable for girls

1, mountaineering. Suitable for people: IT people who work in dark computer rooms. Reason: IT people are in the closed computer room all day, and are troubled by the turbid gas and radiation emitted by the computer all day.

Go mountain climbing on weekends, let yourself be in nature, breathe heartily, sweat heartily, and throw away the boredom and fatigue of the week. Fitness effect: Mountaineering is an excellent aerobic exercise, which can promote metabolism, accelerate blood circulation, improve endurance and leg strength, and enhance cardiopulmonary function.

2. Shopping. Suitable for the crowd: women who stay in the office from morning till night. Reason: This is one of the most popular leisure ways for women, and it is also a good aerobic exercise.
