You can also subtract your age from 200 to get your maximum heart rate. For example, 200-25= 175, then 175 is your maximum heart rate. When you multiply it by 65%-80%, it is14-/kloc-. Anaerobic training should be kept between 75% and 90%, and this can be calculated by yourself.
Measuring exercise heart rate is to better maintain a certain range of exercise, not to be injured, and to control physical fitness to release glycogen in your body on average in a training class. The common method is to measure the heart rate of the member 10 second, and then multiply it by 6 to calculate the exercise heart rate.
Extended data:
The first one is: target heart rate = (maximum heart rate-static heart rate) x intensity percentage+static heart rate.
The second is: target heart rate = maximum heart rate x intensity percentage.
Most people will use the above two formulas to control the intensity during aerobic exercise, but many people will mistakenly think that the first formula is just a safer and more effective formula, but it is not. There are two ways to control the intensity of aerobic exercise: one is to use the percentage of the maximum heart rate, and the other is to use the percentage of the maximum oxygen consumption, which is often higher than the percentage of the maximum intensity 10%, that is, the intensity of 60% of the maximum heart rate is equal to the intensity of 50% of the maximum oxygen consumption.
The exercise intensity calculated by the first formula above is actually the exercise intensity equivalent to the maximum oxygen consumption. Because the individual's static heart rate is added, it is safer, but don't confuse it with the percentage of the maximum heart rate when setting the intensity, otherwise problems will easily occur when arranging training for special people.
