ch 8 - Heart Rate Reserve

How to find heart rate reserve:

1) Find max heart rate (220-age) 2) find resting heart rate 3) subtract resting heart rate from Max Heart rate to get your reserve

an example for a 20-year-old with a resting heart rate of 65bpm who wants to train at 80% maximum would be:

220-20= 200bpm (max heart rate) 200-65= 135bpm (heart rate reserve) (135 x 0.8) + 65= 173 (target heart rate) With the Karvonen formula this person's target heart rate works out as 173bpm.

Heart Rate Reserve is perhaps a better and more accurate method that can be used to prescribe exercise __________ and set target heart rate _________. It has also been found to compare well with oxygen consumption reserve for estimating exercise _______ expended at different exertion levels.

intensity; zones; energy

Heart rate reserve is simply the difference between your _____ heart rate and your _____ heart rate.

max; resting

The Karvonen formula uses one's heart rate reserve to calculate ______ ________ based on both maximum AND resting heart rate.

training zones

(t/f) the heart rate reserve method of prescribing exercise intensity is not 100% accurate.

true, estimating one's max heart rate has shown to have inaccuracies compared to lab testing and heart rate reserve tells us nothing about a person's lactate or anaerobic threshold.
