Q

How is appropriate Intensity of Aerobic Exercise determined? (aka Target HR Zone, THR)

A

Established from lower and upper HR limits depending on pt’s age, fitness level, health status, and goals using 1 of 2 formulas: HRmax or HRR/Karvonen Formula

Q

HRR aka Karvonen Formula for Target HR

A

Lower THR = [(HRmax-HRrest) x 40%)] + HRrest

Upper THR = [(HRmax-HRrest) x 85%)] + HRrest

Q

Normal Cardiorespiratory Response to acute Aerobic Exercise (4)

A

1) Inc O2 consumption from inc CO, inc blood flow, and inc O2 utilization in skeletal muscles
2) Linear increase in SBP wit increasing workload (8-12 mmHg per MET)
3) No change or moderate decrease in DBP
4) Inc RR and tidal volume
