Answer:
we would expect the 30-year-old male with a resting heart rate of 65 per minute to exercise approximately 1.55 hours per week.
Explanation:
Based on the information given, we can estimate the amount of exercise a 30-year-old male with a resting heart rate of 65 per minute would be expected to do per week.
To determine the exercise duration, we need to consider the target heart rate zone for aerobic exercise. This zone is typically defined as 50-85% of the maximum heart rate. The maximum heart rate can be estimated using the formula: 220 minus the person's age.
For a 30-year-old male, the estimated maximum heart rate would be 220 - 30 = 190 beats per minute.
To find the target heart rate zone, we calculate 50-85% of the maximum heart rate:
- Lower end of the target heart rate zone: 50% of 190 = 95 beats per minute
- Upper end of the target heart rate zone: 85% of 190 = 161.5 beats per minute
Since the resting heart rate is 65 beats per minute, we can calculate the exercise heart rate by subtracting the resting heart rate from the upper end of the target heart rate zone:
Exercise heart rate = Upper end of target heart rate zone - Resting heart rate
Exercise heart rate = 161.5 - 65 = 96.5 beats per minute
Now we have the exercise heart rate, we can estimate the duration of exercise per week. The American Heart Association recommends at least 150 minutes of moderate-intensity aerobic exercise per week.
Moderate-intensity exercise is typically considered to be within the range of 55-69% of the maximum heart rate.
Let's assume our exercise heart rate of 96.5 beats per minute falls within the moderate-intensity range.
To find the exercise duration, we divide the recommended 150 minutes by the exercise heart rate:
Exercise duration = 150 minutes / 96.5 beats per minute
Exercise duration ≈ 1.55 hours per week
Therefore, we would expect the 30-year-old male with a resting heart rate of 65 per minute to exercise approximately 1.55 hours per week.
Please note that this is a rough estimate and individual variations in fitness levels and health conditions can affect the actual exercise duration. It's always best to consult with a healthcare professional for personalized exercise recommendations.
