Description

technical field [0001] The embodiments of the present invention relate to computer technology, and in particular, to a method, device, equipment and storage medium for determining an exercise state. Background technique [0002] As people pay more and more attention to health, their enthusiasm for participating in sports is also unprecedentedly high, and the number of sports groups continues to increase. Swimming, as the second-largest exercise after running, is also the second-largest type of exercise to reduce mortality, second only to ball sports. However, most swimmers need to manually count or use equipment to record, but the equipment and methods currently used for swimming status and parameter recording mainly use wearable devices equipped with GPS and nine-axis sensors, such as Apple Watch and Garmin watches. The price is more than 1,000 yuan, and the cost is relatively high. Among them, the power consumption of the GPS module is relatively high, and it is difficult...
