Background technology
When carrying out exercise, need perform physical exercise with suitable intensity for the body-building target.Heart rate is to measure one of measuring of exercise intensity level or consumption level the most accurately.Healthy heart is crucial for people's aerobic endurance.For general exercise and professional contest purpose, aerobic endurance all is extremely important for various types of motions.For follow the trail of with the progress of increased exercise improving aerobic endurance, heart monitor all is one of the most effective aid.
For example, if there is the people to plan to lose weight and consume fat through exercise, desirable situation is that the 60-70% with maximum heart rate performs physical exercise.And for the people who plans to improve cardiovascular health, performing physical exercise with the 70-80% of maximum heart rate is more suitably.Intensity with mistake performs physical exercise, and only fritters away energy, even can hurt health.
Heart rate can easily check out, for example check the pulsation in 15 seconds and calculate the per minute how many times through the pulsation with hand inspection wrist place when taking exercise.But when taking exercise, it is not only inconvenient that pulsation is calculated in stop motion, also can upset and take exercise and heart rate.The mode of this inspection pulsation is brought pressure to neck arteries, and can reduce heart rate.The electronics heart rate monitor is effectively to follow the trail of and write down the mode of the heart rate of whole exercise process.The electronics heart rate monitor not only provides the complete heart rate record of exercise period, and more accurate than manual examination (check) method.
For the entrant of specialty, cardio-pulmonary function is the most important factor relevant with speed.The operating rate of measuring heart is to confirm from take exercise, be benefited what one of method the most accurately of sportsman.Heart rate monitor also helps avoid the excessive weight to health.Heart rate monitor is the maximization train on, minimizes the useful tool of damage probability simultaneously.Heart rate monitor helps the entrant of specialty under certain maximum, to perform physical exercise, and promptly avoids exhausting the glycogen storage of health and guarantees that health has the intensity exercise that the energy execution needs energy.
For health exercising, heart rate monitor is served as the coach who guides the user, when the user can also more take exercise, lets the user take exercise more hardy.Other vital sign for example body temp, SpO2 (blood oxygen saturation that records with pulse oximeter) also is important information for the situation of confirming health.
The equipment that much can measure people's vital sign is arranged.For example, the user can obtain body temperature through using infrared ear temperature meter, clinical clinical thermometer, obtains the amount of the oxygen that heart rate and haemoglobin carry through the use pulse oximeter.But all these equipment all can not be monitored vital sign continuously when the user performs physical exercise.For example, thermometer should not use when the user moves.As for the finger pulse oximeter; Relevant research shows that athletic meeting changes blood volume; Measure invalid (list of references: " Motion Artifact in Pulse Oximetry ", M.R.Neuman and N.Wang, Annual International Conference of the IEEE Engineering in Medicine and Biology Society thereby make; Vol.12 No.5,1990.).
Most of common heart rate monitor are all used the pectoral girdle of ECG type, this pectoral girdle and sports watch (sport watch) wireless connections.ECG signal through measuring from pectoral girdle detects heartbeat, and through wireless connections pulsation is sent to sports watch.Such heart rate monitor accurately and reliably, but its defective is that the user dresses plastic tape when taking exercise be uncomfortable.Pectoral girdle can become very dirty after using.
The another kind of method that detects heart rate is to use infrared (IR) LED and the infrared sensor that leads to ear-lobe or finger tip.Such detecting device has this intrinsic problem of motion artifact, and it is unreliable when the user takes exercise, to become.
In addition, the equipment of existing detection vital sign uses when motion the time is used and moved except that above-mentioned inconvenience to be had the bigger error, does not also take measures, reminds user's function in real time.
