target heart rate and estimated maximum heart rate during exercise (sport)

Target Heart Rate and Estimated Maximum Heart Rate
- one way of monitoring physical activity intensity is to determine whether
a person's pulse or heart rate is within the target zone during physical activity
- for moderate-intensity physical activity, a person's target heart
rate should be 50 to 70% of his or her maximum heart rate.
- maximum rate is based on the person's age. An estimate of a
person's maximum age-related heart rate can be obtained by subtracting
the person's age from 220
- for example, for a 50-year-old person, the estimated maximum
age-related heart rate would be calculated as 220 - 50 years =
170 beats per minute (bpm)
- 50% and 70% levels would be: 50% level: 170 x 0.50 = 85
bpm, and 70% level: 170 x 0.70 = 119 bpm
- therefore moderate-intensity physical activity for a
50-year-old person will require that the heart rate remains
between 85 and 119 bpm during physical activity
- therefore moderate-intensity physical activity for a
50-year-old person will require that the heart rate remains
between 85 and 119 bpm during physical activity
- 50% and 70% levels would be: 50% level: 170 x 0.50 = 85
bpm, and 70% level: 170 x 0.70 = 119 bpm
- for example, for a 50-year-old person, the estimated maximum
age-related heart rate would be calculated as 220 - 50 years =
170 beats per minute (bpm)
- maximum rate is based on the person's age. An estimate of a
person's maximum age-related heart rate can be obtained by subtracting
the person's age from 220
- for vigorous-intensity physical activity, a person's target heart
rate should be 70 to 85% of his or her maximum heart rate
- to calculate this range, follow the same formula as used above,
except change "50 and 70%" to "70 and 85%"
- for example, for a 35-year-old person, the estimated maximum
age-related heart rate would be calculated as 220 - 35 years =
185 beats per minute (bpm)
- 70% and 85% levels would be:
- 70% level: 185 x 0.70 = 130 bpm, and 85% level: 185
x 0.85 = 157 bpm
- therefore vigorous-intensity physical activity for a 35-year-old person will require that the heart rate remains between 130 and 157 bpm during physical activity.
- 70% level: 185 x 0.70 = 130 bpm, and 85% level: 185
x 0.85 = 157 bpm
- 70% and 85% levels would be:
- for example, for a 35-year-old person, the estimated maximum
age-related heart rate would be calculated as 220 - 35 years =
185 beats per minute (bpm)

- for moderate-intensity physical activity, a person's target heart
rate should be 50 to 70% of his or her maximum heart rate.
Taking Your Heart Rate Person correctly taking their heart rate
- usually, in order to determine whether you are exercising within the heart
rate target zone, you must stop exercising briefly to take your pulse (or
use a heart rate monitor)
- can take the pulse at the neck, the wrist, or the chest
- recommend to take the pulse at the wrist (1)
- feel the radial pulse on the artery of the wrist in line with the thumb. Place the tips of the index and middle fingers over the artery and press lightly. Do not use the thumb.
- take a full 60-second count of the heartbeats, or take for 30 seconds and multiply by two
- recommend to take the pulse at the wrist (1)
- can take the pulse at the neck, the wrist, or the chest
