Question 2

Age and resting heart rate

The Karvonen method for calculating target heart rate zone utilizes age and resting heart rate as its primary characteristics. This approach helps in determining the appropriate intensity of exercise based on an individual's physiological conditions.

A) Weight and resting heart rate

This option is incorrect because weight is not a direct factor in the Karvonen method. The method specifically requires resting heart rate and age to accurately calculate the target heart rate zone, making weight irrelevant in this context.

B) VO2 max and age

While VO2 max is an important measure of cardiovascular fitness, it is not utilized in the Karvonen method. This method focuses on age and resting heart rate for determining heart rate zones, hence this option is not correct.

C) Age and resting heart rate

This is the correct answer as the Karvonen method specifically incorporates both age and resting heart rate to calculate the target heart rate zone. These two factors are essential for tailoring exercise intensity to individual fitness levels.

D) Resting heart rate and VO2 max

This option is incorrect because, although resting heart rate is a component of the Karvonen method, VO2 max is not included. The method relies on age alongside resting heart rate to establish the target heart rate zone effectively.

Conclusion

The correct answer, age and resting heart rate, is fundamental to the Karvonen method as it allows for personalized exercise intensity calculations. All other options fail to incorporate the necessary components required by this method, thereby confirming the significance of age and resting heart rate in establishing target heart rates.
