Question

(220 - 14) X .80

Answer 1

60%-80% of MHR = My Target Heart Rate Range (THRR) is 124 to 165

Answer 2

To calculate \( (220 - 14) \times 0.80 \):

1. First, subtract 14 from 220:
\[
220 - 14 = 206
\]

2. Then, multiply the result by 0.80:
\[
206 \times 0.80 = 164.8
\]

So, \( (220 - 14) \times 0.80 = 164.8 \).

Answer 3

To understand how you arrived at the Target Heart Rate Range (THRR) of 124 to 165 beats per minute (bpm) based on a percentage of your Maximum Heart Rate (MHR), let's break down the calculations:

1. **Determine MHR**:
- The formula for estimating Maximum Heart Rate is \( MHR = 220 - \text{age} \). If 124 to 165 is your THRR, we can calculate MHR using the given percentages.

2. **Calculate MHR from THRR**:
- If we denote MHR as \( x \):
- 60% of MHR:
\[
0.60 \times x = 124
\]
\[
x = \frac{124}{0.60} \approx 206.67
\]
- 80% of MHR:
\[
0.80 \times x = 165
\]
\[
x = \frac{165}{0.80} \approx 206.25
\]

3. **Approximate MHR**:
- Both calculations suggest that your MHR is around 206 bpm.

4. **Find Age**:
- Using the MHR formula:
\[
220 - \text{age} = 206
\]
\[
\text{age} = 220 - 206 = 14
\]

This means that if you are 14 years old, your MHR is indeed estimated to be around 206 bpm. Your target heart rate range during exercise, calculated as 60% to 80% of MHR, would then be accurately expressed as 124 to 165 bpm.
