Karvonen Method For Estimating Target HR (Part 2 of 2)

The video tutorial explains how to determine a target heart rate for different exercise intensities using the Karvonen formula. It highlights the limitations of a simple heart rate formula and introduces the concept of heart rate reserve, which accounts for individual fitness levels. The tutorial provides a detailed calculation of target heart rate and compares the results for individuals with different fitness levels. Finally, it demonstrates how to calculate a range of target heart rates, emphasizing the accuracy of the Karvonen formula.

What is the lower limit percentage of maximum intensity used in the basic target heart rate formula?

• 70%

• 85%

• 50%

• 30%

What is the upper limit percentage of maximum intensity used in the basic target heart rate formula?

• 70%

• 60%

• 50%

• 85%

Why might two people with the same estimated maximum heart rate have different target heart rates?

• Different diets

• Different exercise routines

• Different resting heart rates

• Different ages

How is Heart Rate Reserve (HRR) calculated?

• Maximum heart rate minus resting heart rate

• Resting heart rate minus age

• Resting heart rate plus age

• Maximum heart rate minus age

In the example given, what is the target heart rate for a 30-year-old with a resting heart rate of 60 bpm exercising at 50% intensity?

• 150 bpm

• 140 bpm

• 130 bpm

• 124 bpm

What is the formula for calculating maximum heart rate in the example provided?

• 220 minus age

• 208 minus 0.7 times age

• 200 minus age

• 210 minus 0.5 times age

What does a higher Heart Rate Reserve indicate about a person's fitness level?

• They are less fit

• They are more fit

• They have a higher maximum heart rate

• They have a lower maximum heart rate

How does a sedentary lifestyle affect target heart rate at the same intensity compared to a fit person?

• It makes the target heart rate equal

• It has no effect

• It raises the target heart rate

• It lowers the target heart rate

What is the target heart rate range for a person exercising between 50% and 60% intensity using the Karvonen formula?

• 150-160 bpm

• 120-130 bpm

• 140-150 bpm

• 131-142 bpm

Why is the Karvonen formula considered more accurate than the basic formula?

• It uses a different maximum heart rate

• It includes resting heart rate

• It is simpler to calculate

• It only considers age
