High-intensity intermittent exercise can reduce fat. Don't ignore the three major danger signs

Ming Dao, the once popular male lead in idol dramas, has become obsessed with high-intensity interval training in recent years and has developed a good body. This sport trend has long been loved by Hollywood movie stars. "High-intensity interval training (HIIT)" is very popular nowadays, and it is said to be able to effectively build muscle and reduce fat. However, many people find themselves out of breath and their hearts are racing when they practice by following the videos on the Internet, which makes people wonder, is this really a safe and effective way to lose weight?

High-intensity interval training is more suitable for athletes

Han Wei, director of Shin Kong Orthopedic Sports Medicine Center, explained that high-intensity exercise means that the heart rate must reach more than 200% of the normal heart rate, and the calories consumed per minute are much higher than aerobic exercise. This level of exercise is more suitable for athletes and is not recommended for ordinary people or those who want to lose weight quickly.

High-intensity interval exercise is a type of anaerobic exercise. Because it is a short-term high-intensity exercise, the breathing and heart rate increase significantly, which can easily cause the myocardium to swell and even block blood vessels, causing a sudden interruption of blood circulation, which may induce myocardial infarction. Doctors remind that patients with diabetes and cardiovascular disease should try to choose aerobic exercise.

If you feel uncomfortable during high-intensity interval training, you should stop immediately

Recently, "Everyone's Health Magazine" reported that Ye Yaxin, director of the Mental Health Center of the Tung Foundation, reminded that if beginners feel the following three danger signs when engaging in high-intensity interval training, including: shortness of breath and rapid heartbeat, or dizziness and nausea, and increasing muscle soreness somewhere in the body, it means that the heart and muscles can no longer bear it, and it is recommended to stop exercising immediately.

Research confirms: HIIT helps lose fat

If you are an athlete, high-intensity interval training is more suitable for you. According to a study published in the International Journal of Obesity, a few minutes of HIIT has a better fat-reducing effect than 45 minutes of sustained speed aerobic exercise. If your body can withstand the intensity of high-intensity interval training, it is very suitable for fitness and fat loss.

Aristotle once said: "Too much exercise and too little exercise are equally harmful to the body; too much food and too little food are equally harmful to health; only moderation can produce, enhance, and maintain physical strength and health." The correct exercise method can build a healthy body, but getting hurt because of exercise is putting the cart before the horse. Before engaging in any sport, you should first assess whether you have the ability, and pay attention to the warm-up before exercise, as well as the nutritional intake before, during and after exercise. All aspects need to be taken into consideration.
