Heart Rate Calculations
Yourmaximumheartrateusuallydecreasesfrom220BeatsPerMinute(BPM)inchildhood
toapproximately160BPMbyage60.Thisfallinheartrateisusuallylinear,decreasingby
approximatelyoneBPMforeachyear.Thereisnoindicationthattraininginfluencesthedecrease
inmaximumheartrate.Individualsofthesameagecouldhavedifferentmaximumheartrates.Itis
more accurate to find this value by getting a stress test than by using an age related formula.
Your at-rest heart rate is influenced by endurance training. The typical adult has an at rest heart
rateofapproximately72BPM,whereashighlytrainedrunnersmayhavereadingsof40BPMor
lower.
The Heart Rate table is an estimate of what Heart Rate Zone (HRZ) is effective to burn fat and
improve your cardiovascular system. Physical conditions vary, therefore your individual HRZ could
be several beats higher or lower than what is shown.
