Heart rate: the number of heart beats per minute. The average normal heart rate is 72 beats / min for men and 80 beats / min for women.
Static heart rate: refers to the number of heart beats per minute in the quiet state of ordinary people, also known as the quiet heart rate, generally 60-100 beats / min.
Dynamic heart rate: that is, the continuous dynamic heart rate of the human body during exercise. The stronger the exercise, the higher the heart rate.
Basic pulse: also known as veno venous, that is, the heart rate value in a quiet and comfortable state. It is usually the heart rate in the supine position before getting up in the morning. The average person is stable at about 70 times / min.
Raise your hand to light up the screen: when you wear a heart rate bracelet, raise your arm to light up the screen automatically. The main purpose is to facilitate viewing.
Wristband switching: when wearing the heart rate bracelet, the function interface inside the wristband will automatically switch to the next function.
Heart rate warning: when the heart rate exceeds the preset warning value, the bracelet will vibrate to remind.
IP67 waterproof: it is a protection security level. IP is the abbreviation of advance protection rating, which refers to the protection ability of an interface against liquid and solid particles. IP67 is followed by two digits, the first digit is the solid state protection level (its range is 0-6); The second number is the degree of protection against liquids (it ranges from 0 to 8). The larger the number is, the stronger its protection capability is. Generally speaking, it is enough that we can reach ipx-7 level for outdoor equipment.
Maximum heart rate: people of different ages have different maximum heart rate, formula: maximum heart rate = 220 - age.
Aerobic exercise: refers to the physical exercise carried out by the human body under the condition of sufficient supply of oxygen.
Anaerobic exercise: refers to the muscle in the "hypoxia" state of high-speed intense exercise. Most of the anaerobic exercise is the exercise with high load intensity and strong instantaneity, so it is difficult to last for a long time, and the time of fatigue elimination is also slow.
Single real-time step counting throughout the day: that is, off-line events, through the motion monitoring function of the bracelet. When it is turned on and off, an offline event is generated.
Calorie (CAL): unit of energy, defined as the amount of heat required to raise 1 gram of water by 1 degree centigrade at 1 atmospheric pressure.
Blood oxygen (spo2h): refers to the oxygen in the blood, the normal oxygen content of the human body is about 90%.
Blood pressure (BP): it is the pressure acting on the wall of blood vessel when blood flows in blood vessel. It is the power to promote blood flow in blood vessel.
Blood oxygen saturation (SpO2): it is the percentage of the capacity of oxygenated hemoglobin (HBO2) bound by oxygen in the blood, that is, the concentration of blood oxygen in the blood. It is an important physiological parameter of respiratory circulation.
