Methods of Estimating Intensity of Cardiorespiratory Exercise

Vocabulary flashcards covering methods, metrics, intensity ranges, and definitions for cardiorespiratory exercise estimation.

HRmax

Maximal heart rate.

HRR

Heart rate reserve.

MET

Metabolic equivalent.

RPE

Rating of perceived exertion on a 6-20 scale.

VO2max

Maximal volume of oxygen consumed per unit time.

VO2R

Oxygen uptake reserve.

Very Light Intensity

Cardiorespiratory endurance exercise intensity classified by $<30\%$ HRR or %VO2R, $<57\%$ HRmax, $<37\%$ VO2max, and an RPE of $<9$.

Light Intensity

Cardiorespiratory endurance exercise intensity classified by $30-39\%$ HRR or %VO2R, $57-63\%$ HRmax, $37-45\%$ VO2max, and an RPE of $9-11$ (very light to fairly light).

Moderate Intensity

Cardiorespiratory endurance exercise intensity classified by $40-59\%$ HRR or %VO2R, $64-76\%$ HRmax, $46-63\%$ VO2max, and an RPE of $12-13$ (fairly light to somewhat hard).

Vigorous Intensity

Cardiorespiratory endurance exercise intensity classified by $60-89\%$ HRR or %VO2R, $77-95\%$ HRmax, $64-90\%$ VO2max, and an RPE of $14-17$ (somewhat hard to very hard).

Near-Maximal to Maximal Intensity

Cardiorespiratory endurance exercise intensity classified by $\ge 90\%$ HRR or %VO2R, $\ge 96\%$ HRmax, $\ge 91\%$ VO2max, and an RPE of $\ge 18$ (very hard to maximal).

Young Adult Absolute Intensity (20-39 yr)

Absolute exercise intensity measured in METs for ages 20-39: Very Light ($<2.4$ METs), Light ($2.4-4.7$ METs), Moderate ($4.8-7.1$ METs), Vigorous ($7.2-10.1$ METs), and Near-maximal to maximal ($\ge 10.2$ METs).

Middle Age Absolute Intensity (40-64 yr)

Absolute exercise intensity measured in METs for ages 40-64: Very Light ($<2.0$ METs), Light ($2.0-3.9$ METs), Moderate ($4.0-5.9$ METs), Vigorous ($6.0-8.4$ METs), and Near-maximal to maximal ($\ge 8.5$ METs).

Older Adult Absolute Intensity (\ge 65 yr)

Absolute exercise intensity measured in METs for ages 65 and older: Very Light ($<1.6$ METs), Light ($1.6-3.1$ METs), Moderate ($3.2-4.7$ METs), Vigorous ($4.8-6.7$ METs), and Near-maximal to maximal ($\ge 6.8$ METs).
