Terms for Pulse monitoring

• Resting Heart Rate--RHR• women average 78-84; men 72-78• affected by digestion, medication, activity

Terms

• Maximal Heart Rate--MHR• determined by stress test• but 220-age is good estimate

Terms

• Training Heart Rate Range--THRR• range where training occurs• low end for deconditioned; high for athletes

Checking the pulse• Radial

• thumb side of left wrist, palm up• use index & middle finger, not thumb

• Carotid• side of neck by Adam’s apple• avoid pressing hard or using thumb• don’t touch opposite side

• 10 seconds x 6 to convert to bpm• or 6 seconds x 10 (easiest)

taken immediately after exercise

keep walking

Exercise Pulse Rates

Karvonen Formula Determine MHR (220-age) Subtract rhr from that number.

This is called HRR, heart rate reserve.

Multiply HRR by .50 to .85 to get upper and lower ends of THRR intensity.

Add RHR back into the formula.

Karvonen Formula Pregnant women should use

50% as their intensity. Folks in poor condition use 55-

75% Folks in fair condition can use

60-80% intensity. Folks in excellent condition can

work at 65-85%.

Karvonen Formula For an 18 year old with RHR of 72 In “fair” cardio condition

Karvonen example:• 220-18=202220-18=202• 202-72=130202-72=130• x.60=78x.60=78• x.80=104x.80=104• +72=150-176+72=150-176

This means this This means this persons heart must persons heart must beat 150-176 in order beat 150-176 in order to improve the to improve the cardio system.cardio system.
