For physical activity of vigorous intensity, an individual's target heart rate should be within what range of their maximum heart rate?

To calculate the target heart rate for vigorous intensity physical activity, you first need to determine your maximum heart rate. This can be estimated by subtracting your age from 220.

Once you have your maximum heart rate, you can calculate the range for vigorous intensity activity, which is typically 70% to 85% of your maximum heart rate.

Here are the steps:

1. Subtract your age from 220 to find your maximum heart rate.
2. Multiply your maximum heart rate by 0.70 to find the lower limit of your target heart rate zone for vigorous intensity activity.
3. Multiply your maximum heart rate by 0.85 to find the upper limit of your target heart rate zone for vigorous intensity activity.

For example, if you are 30 years old:

1. Your maximum heart rate would be 220 - 30 = 190 beats per minute.
2. The lower limit of your target heart rate zone would be 190 * 0.70 = 133 beats per minute.
3. The upper limit of your target heart rate zone would be 190 * 0.85 = 162 beats per minute.

So, for vigorous intensity activity, a 30-year-old's target heart rate should be within the range of 133 to 162 beats per minute.
