Terminology

Maximum Heart Rate

The heart rate increases according to the intensity of exercise, but there is a limit. The highest heart rate that a person can sustain is called the "maxi- mum heart rate". Generally the maximum heart rate declines as we get older, however this differs between individuals, and is largely due to how much a person exercises.

The difference between heart rate and pulse rate

The heart rate is the number of heartbeats per minute measured by an electrocardiograph. On the other hand, the pulse rate is measured as fol- lows.

•From the palpations of an artery near the skin surface, such as the ca- rotid artery

•By passing a sensor light through an earlobe or fingertip, and measuring the pulse count via the subtle changes of the sensor light transmission caused by the heart beat

Although the measurement principle and method are different, both the heart and pulse rates have the same value per minute, and are therefore

regarded as synonymous.

Pulse Limit

For the standard maximum heart rate, "220 - Age", "204 - 0.69 x Age", and other formulas are used. In the EC-T220, however, "200 - Age" is used, taking into account a certain safety margin, and is incorporated in the computer setting.

Target Pulse Rate

		Age

The pulse rate you should maintain during a workout is called the "target pulse rate". The automatic training program allows you to stay close to this target, but it is recommended that you always be conscious of your pulse rate, even when performing different types of training programs, by referring to the "Target Pulse Rate Chart". You can input a target pulse rate up to 85% of the maximum pulse rate.

Exercise Level Based on the Pulse Rate

Pulse rate increases according to the intensity of the exercise. In other words, the pulse rate during exercise is a measure for the exercise level. The exercise level can be expressed in percentages by using the following formula.

Pulse rate during exercise - Pulse rate at rest

Exercise level(%) =		x 100
	Maximum heart rate - Pulse rate at rest

Therefore, if you want to determine the target exercise level (target pulse rate) from the pulse rate, you can calculate as follows.

Target pulse rate = (maximum heart rate - pulse rate at rest) Exercise level(%)

x + pulse rate at rest

100

If you are a beginner, you can start the exercise with a target pulse rate of "160 - your age". If you can continue your exercise at the target pulse rate of "180 - your age," your exercise can be considered effective enough. Upgrade your exercise gradually so that you can reach the suggested final target of "190 - your age".
