Bagaimana menentukan kadar
nadi maksima (maxHR)
• Mengetahui terlebih dahulu kadar nadi
maksima sebelum menentukan latihan tahap
ambang dan kadar nadi latihan
• Kadar nadi maksima merupakan kadar nadi
tertinggi apabila melakukan aktiviti fizikal
(220-umur)= kadar nadi maksima
* formula ini hanya anggaran,terdapat anggaran yang terbaru bergantung
dengan umur.
• Berdasarkan penyelidikan dan kajian semula formula
baharu yang di syorkan untuk menganggarkan kadar
nadi latihan (THR)
kadar nadi maksima=208-(0.7xumur)
Sesuai untuk kedua2 jantina
Contoh:
Remaja berumur 22 tahun
=208-(0.7x22)
=208-15.4
=192.6
=193 denyutan seminit(maxHR)(kadar nadi maksima)
• Contoh mengira tahap ambang dan kadar nadi
latihan (THR) dengan menggunakan kaedah
%an heart rate reserve (HRR) bagi remaja
umur 22thn
kadar nadi maksima (KNM)=193 dsm
kadar nadi rehat (KNR) = 68 dsm
maka heart rate reserve (HRR) = KNM-KNR
= 193-68
= 125 dsm
• Kadar nadi tahap ambang
heart rate reserve (HRR)= 125 dsmx peratus intensiti
kerja(40%)
= 125x40/100
= 125x0.40
= 50 dsm + kadar nadi rehat (KNR)
= 50+68
= 118 dsm
Sub maksima kadar nadi
heart rate reserve (HRR) = 125 dsm x peratus intensiti kerja (85%)
= 125x0.85
= 106.25
= 106 dsm + KNR
= 106 + 68
= 174 dsm

Kadar nadi maksima (maxHR)= 193 dsmx % intensiti
kerja(55%)
= 193x0.55
= 106.15
= 106 dsm
Sub maksima kadar nadi
Kadar nadi maksima (maxHR) = 193dsmx % intensiti kerja (90%)
=193x0.90
=173.7
