I believe that there are many sports-loving friends around you, and they are now wearing different watches when they are exercising. Many friends don’t know what these sports watches have. Why do you like to wear them?
1. The function of the step-by-step sports watch: its motion sensor is a 3D acceleration sensor, which can sense the three-dimensional motion acceleration generated when the human body moves, thereby recording the number of steps per unit time; calculating the speed and distance of the human body motion by the input step size. And by inputting the body weight, thereby deriving calories burned, it has the advantage that it can be used indoors and outdoors, is weather-proof and very power-saving, and can store motion data for several days.
2, heart rate sports watch function: It mainly uses the heart current of the human body to measure the heart rate of the human body. The body has different intensity of heart and heart rate at different heights; internationally, the percentage of the heart rate of the heart to the maximum heart rate is divided into light. Activity: 50-60%, aerobic exercise: 60-75%, endurance training: 75-85%, intensity training 85%-100%; choose different heart rate areas to achieve different training and exercise effects.
3, GPS sports watch function: by receiving the satellite position signal WAYPOINT to calculate the distance moved per unit time, and calculate the speed of the movement; the accuracy of the position signal is determined by the strength of the satellite signal, the sampling rate; such as 1 second sampling The accuracy of the rate is obviously higher than the 60 second sampling rate, but too high a sampling rate will cause the battery to consume too fast. It has the advantage of recording the motion trajectory and synchronizing to the map.
