Karvonen Heart Rate Formula

Også kjent som: Target Heart Rate Formula, Heart Rate Reserve Method

THR = ((HR_{max} - HR_{rest}) \times \%intensity) + HR_{rest}

THR = (HRmax - HRrest) × %intensity + HRrest

Hva den beregner

Calculates target heart rate for a specific training intensity using heart rate reserve (HRR). More personalized than simple percentage of max HR because it accounts for resting heart rate.

variabler

Symbol	Navn	Enhet	Beskrivelse
THR	Target Heart Rate	bpm	Heart rate to aim for during exercise
HR_{max}	Max Heart Rate	bpm	Maximum heart rate (220 - age)
HR_{rest}	Resting Heart Rate	bpm	Heart rate at complete rest
%intensity	Intensity	decimal	Desired exercise intensity (e.g., 0.70 for 70%)

Arbeidseksempler

1HRR = 185 - 65 = 120

2THR = 120 × 0.70 + 65 = 84 + 65 = 149 bpm

Resultat: 149 bpm
