At the beginning of fitness, the pulse during exercise should be controlled at 60%-70% of the pulse per minute (pulse =220- age), and it can be increased to 70%-85% after 2-3 months of exercise. There is also a certain relationship between the rhythm of music and heart rate during bodybuilding. The ideal pulse rhythm of healthy adults should be about 60 beats per minute, and the rhythm of about 60 beats per minute (medium speed) is just suitable for people's normal physiological rhythm. If music adopts the rhythm of this speed, so that people can keep balance between body and mind and breathe smoothly in blood vessels, it is the rhythm of conditioning physiology (yoga music adopts this rhythm). Choosing the music rhythm below 60 beats per minute will inhibit and delay the physiological rhythm of human body (hypnosis is this rhythm). Conversely, if you choose a music rhythm of more than 60 beats per minute, it will be exciting and can promote physiological and biochemical effects. For example, the disco music rhythm is about 120 beats per minute, almost twice the physiological rhythm, which can stimulate the bioactive substances in the human body and make the mood excited. In short, in bodybuilding, we should master the pulse rate and choose the appropriate music rhythm according to everyone's age, physical condition and other different situations, which has a good promotion effect on the body. ?
