Fat is the main cause of our obesity, so when many people want to lose weight, their first reaction is to consume fat. Exercise is the most effective way to burn fat, but it requires a certain amount of time. So how many minutes do you think it is best to exercise to burn fat? Let’s go take a look below!
The best number of minutes of fat-burning exercise< /strong>
It is best to exercise for more than 40 minutes to consume fat. Studies have shown that the first 20 minutes of aerobic exercise will hardly mobilize subcutaneous fat, but will consume free fat in the blood. Mobilization of non-free adipose tissue begins after 20 minutes. As exercise time increases, the proportion of fat decomposed for energy gradually increases. Starting from about 40 minutes of aerobic exercise, fat becomes the main substance for energy supply. But this does not mean that the first 20 minutes of aerobic exercise are ineffective for fat consumption. Moreover, the three major substances, sugar, fat and protein, are converted into each other in the human body, which means that even if you exercise for less than 20 minutes, you can still consume fat.
The more muscle groups involved in the work per unit time, the better the training effect will be. For example, if you mobilize all the muscles of the body and walk quickly on a treadmill, even though it only lasts for 10 minutes, the amount of calories metabolized is no less than running for 30 minutes without tightening the muscles. "Of course, the general recommendation for aerobic training is about 30 to 40 minutes. However, the prerequisite is to allow all the muscles of the body to participate in the training as much as possible. This is the most important.
Is muscle soreness effective after exercise?
Muscles after exercise Soreness is known in sports medicine as "delayed onset muscle soreness (DOMS)" and is usually experienced during exercise.It appears 24 hours after it ends, the pain reaches its peak within 24-72 hours, and basically disappears after 5-7 days.
DOMS is often caused when new training is started or after a sudden high-intensity eccentric exercise. Experiments and research show that the human body has a strong adaptability. After a few trainings, you will gradually get used to it and no longer feel sore. However, this does not mean that the training effect has become worse, but that your body has gradually become familiar with it. New training moves and intensities. Therefore, the degree of muscle soreness after exercise is not an indicator of the effectiveness of training.
There are many reasons for muscle soreness. Infrequent exercise, increasing exercise intensity, and restarting exercise after stopping exercise for a period of time may all cause muscle soreness. When exercising, you need to control the intensity and strengthen it step by step. In addition, occasional muscle soreness can help us realize which part of the body lacks exercise, thereby strengthening the exercise of the corresponding part and reducing muscle soreness.
