Calorie (Cal for short), transliterated from English Calorie, is defined as the heat required to raise 1 gram of water to 1 degree Celsius at 1 atmospheric pressure; Calorie is an energy unit, which is still widely used in nutrition measurement and fitness manual. The international standard unit of energy is joule.

As the legal unit of food calories, joules are widely used in Europe, while calories are used in the United States. Although Joule is the legal unit in Chinese mainland and Taiwan Province Province, it is still widely used in Chinese mainland and Taiwan Province Province because of tradition.

Singing is a kind of exercise. Doing exercise inevitably consumes energy, that is, heat, so singing consumes heat.

Why can't singing lose weight?

According to the net post, a study shows that the oxygen consumption of a person after singing a song is equivalent to the oxygen consumption after running 100 meters, which means that singing a song is equivalent to running 100 meters.

Experts believe that this statement is only established in theory, but it is difficult to do it in real karaoke. For example, abdominal breathing, if you want to exercise, you must meet at least four elements:

The first breath should be deep, long and slow, which is very difficult for ordinary songs;

The second is to inhale through the nose and exhale through the mouth. Many fast songs will unconsciously inhale through the mouth and exhale through the nose when singing;

Third, the process of inhaling and exhaling is generally more than 10 second, that is, deeply inhaling (bulging abdomen) for 3-5 seconds, holding your breath 1 second, and then slowly exhaling (contracting abdomen) for 3-5 seconds, holding your breath 1 second. It is estimated that few people can do it when singing;

Fourth, abdominal breathing exercises for 5 ~ 15 minutes at a time, preferably for 30 minutes, but it is impossible for a person to sing karaoke without rest.

Experts also said that "singing a song is equal to running 100 meters".

It is said on the Internet that a person's oxygen consumption after singing a song is equivalent to that after running 100m, but this does not mean that singing a song is equivalent to running 100m. Oxygen consumption and fat consumption are not the same concept, and high oxygen consumption does not mean burning fat to lose weight.
