Running on an empty stomach in the morning will accelerate fat burning.
Fasting training can accelerate fat burning and metabolic rate. A research experiment on overweight people shows that the fat consumption of walking on an empty stomach before breakfast is about 33% higher than that of walking after breakfast. This is because exercise requires energy, and the main source of human energy is the carbohydrate intake in the diet. When exercising on an empty stomach, such as running before breakfast, the concentration of glycogen in the body is relatively low, and the body will mobilize fat hydrolysis to generate heat. At this time, the energy consumed by running mainly comes from fat.
But for the same reason, runners with cardiovascular diseases should reduce fasting training. High concentration of free fatty acids in plasma may lead to platelet aggregation and thrombosis or arrhythmia. People with hyperlipidemia or hypertension should be very careful.
On the other hand, if the carbohydrate reserve is seriously insufficient to support excessive exercise, protein needs to participate in oxidative energy supply and glucose synthesis, because running on an empty stomach may also cause protein decomposition, thus affecting the normal physiological function of human body. Therefore, even if you are going to lose weight, it is usually not suitable for doing a lot of exercise on an empty stomach. The running time is basically controlled at about 30 minutes to 50 minutes. If the distance of fitness long-distance running is long, you can drink a small glass of sugar water or make a little supplement first.
Benefits of strength training before aerobic exercise:
1, which is beneficial to fat mobilization. First, most glycogen reserves are consumed, which makes aerobic exercise more efficient, accelerates lactic acid metabolism, and glycolysis produces lactic acid accumulation. Aerobic exercise brings lactic acid into aerobic oxidation and carries out complete combustion.
2. It is beneficial to reduce exercise fatigue, accelerate the recovery of the body and increase the secretion of lipolytic hormone. Anaerobic exercise promotes the secretion of lipolytic hormones and increases the fat burning rate.
3, it is beneficial to improve the metabolism level, promote the increase of lean tissue in the body to improve metabolism, and is beneficial to energy consumption.
