Heart Rate Reserve (HRR) is normally calculated as the difference between yourMaximum Heart Rate(HRmax) andResting Heart Rate(HRrest). Exercise intensity can be evaluated by calculating your heart rate as a percentage of HRR. The calculation to work out %HRR is… ...

70% of your “heart rate reserve” is a great estimate of the upper bounds of your Zone 2. If you choose to use approximately 70% of your heart ratereserve… here’s the formula. 70% of your heart rate reserve added to your resting heart rate (so your aerobic threshold would be 0.7...
Luckily, many apps help manage this calculation for you. “I love using Garmin Connect Software and Strava,” says Castro, as you’ll get zone data right in the apps. Just remember, because heart rate maximums using age-predicted formulas are estimates, you may need to adjust your zones ...

By measuring the isovolumic contraction time (IVCT), isovolumic relaxation time (IVRT), and ejection time (ET) indices from the pulsed tissue Doppler velocity of the lateral tricuspid annulus, one avoids errors related to variability in the heart rate. RIMP can be falsely low in conditions ...

Afterload (end-systolic stress) and VCF can be measured directly; and F′′ can be solved for c. The observed heart rate (ν) and calculated contractility (c) can then be substituted in formula (2) to calculate c′. Finally, the observed values for fiber shortening (ΔL) and end-systo...
