Problems solved by technology

[0002] The monitoring of human sports energy consumption and heart rate is of great significance in many fields, and is widely used in medicine, sports training and daily life; in medicine, traditional heart rate measurement methods rely on electrocardiograms for image processing, and professional training is also required in sports training. Instruments and operations cannot meet the requirements of portability, flexibility, and ease of operation; in the prior art, there are also many methods for measuring heart rate through acceleration sensors, but this existing measurement method only plays the role of measurement However, it cannot predict the heart rate of the subject during exercise, and this function is just an important indicator for monitoring human health and pre-judging risks, especially for special groups such as the elderly. The function of heart rate prediction during exercise is particularly important
