Karvonen Formula

Question 1

(MHR) Maximum Heart Rate

Answer 1

Aerobic target zone = 60-80% of your MHR

MHR = 220 - your age

e.g 220 - 14 = 216bpm

Question 2

(RHR) Resting Heart Rate

Answer 2

RHR = wrist/neck and count for 1min, so your RHR = 66 bpm

Question 3

(HRR) Heart Rate Reserve

Answer 3

‘HRR = MHR - RHR’ so your ‘HRR = BPM’

Question 4

(BPM) Beats Pear Minute

Answer 4

Used by MHR, RHR and HRR

Question 5

Target heart rate formula

Answer 5

(HRR x training %) + RHR = target heart rate

e.g. 90
(HRR 150 x 0.6) + RHR 66 = 156
(HRR 150 x 0.8) + RHR 66 = 186
120
