A client is 45 years old and has a resting heart rate of 75 bpm. Using the Karvonen formula, what is their target heart rate at an exercise intensity of 60%

The target heart rate is 120.9bpm

The Karvonen Formula is a mathematical formula that is used to determine the target heart rate (HR) training zone at a particular exercise intensity. In order to get the target heart rate required, the expression needed make use of the  maximum and resting heart rate with the desired training intensity given.

Mathematically, the target heart rate is expressed as:

Target Heart Rate = [(max HR − resting HR) × %Intensity] + resting HR

Given the following parameters

Resting HR = 75bpm

Maximum heart rate = 208 - (0.7xage )

Maximum heart rate = 208 -(0.7×45)

Max HR = 208-31.5

Max HR = 176.5pm

Exercise intensity = 60% = 0.6

Substitute the given parameters into the formula given above as shown:

Target Heart Rate = [(176.5 − 75) × 0.6] + 60

Target HR = (101.5×0.6)+60

Target HR = 60.9+60

Target HR = 120.9bpm

Therefore the target heart rate is 120.9bpm
