in order to achieve from aerobic exercise, one should maintain one's heart rate at a certain level. A fourty year old women with a reating heart beat of 80 beats per minue should keep her heart rate between 140 and 160 beats per minute while exercising. She checks her pulse for 10 sec while exercising. What should the number of beats be?
140 / 6 = ?
160 / 6 = ?
How much does an adult heart beat in one year, one month, thirty years, one week, ten years, and sixty five years
To find out the number of beats a forty-year-old woman with a resting heart rate of 80 beats per minute should have while exercising, we can follow these steps:
1. Calculate the target heart rate range:
- First, subtract the resting heart rate (80 beats per minute) from the upper end of the target range (160 beats per minute):
Target range upper limit - Resting heart rate = 160 - 80 = 80 beats per minute
- Next, subtract the resting heart rate (80 beats per minute) from the lower end of the target range (140 beats per minute):
Target range lower limit - Resting heart rate = 140 - 80 = 60 beats per minute
2. Convert the target heart rate range to beats per second:
- Divide the calculated beats per minute range by 60 (since there are 60 seconds in a minute):
Upper limit in beats per second = 80 beats per minute ÷ 60 = 1.33 beats per second
Lower limit in beats per second = 60 beats per minute ÷ 60 = 1 beat per second
3. Calculate the number of beats in 10 seconds:
- Multiply the beats per second values by 10 (as you checked your pulse for 10 seconds):
Upper limit: 1.33 beats per second * 10 seconds = 13.3 beats (rounded to 13 beats)
Lower limit: 1 beat per second * 10 seconds = 10 beats
Therefore, while exercising, the number of beats a forty-year-old woman should have in a 10-second pulse check should be between 10 and 13 beats.
