Background technique

Many sports enthusiasts need to control their calorie consumption while exercising. Some running or swimming simulators can provide such a device primarily through sensors installed in the simulator frame, which are used to measure the corresponding actions. But when people are engaged in a real exercise, they use certain sensors to measure and encounter certain problems. At this time, people roughly estimate the average of some exercise parameters by purchasing some wearable devices such as watches.
