Answer :
To determine your estimated maximum heart rate, the most commonly used formula is "220 - your age". This formula gives you an approximation of the maximum heart rate you should reach during exercise, which is a helpful guideline to monitor your exercise intensity.
Let's break it down step-by-step:
1. Understanding the Formula: The correct formula to estimate the maximum heart rate is "220 - your age". This means you start with the number 220 and subtract your current age from it.
2. Applying the Formula: Suppose you want to estimate the maximum heart rate for a 30-year-old individual. Here's how you would do it:
- Start with 220.
- Subtract the person's age, which is 30.
3. Calculation:
- [tex]\( 220 - 30 = 190 \)[/tex]
4. Result: So, for a 30-year-old, the estimated maximum heart rate is 190 beats per minute.
Choosing the correct formula from the options given:
- Option A: [tex]$200 +$[/tex] your age is incorrect.
- Option B: [tex]$220 +$[/tex] your age is incorrect.
- Option C: 200 - your age is incorrect.
- Option D: 220 - your age is correct.
Therefore, the answer is Option D: 220 - your age.
