ACSM Cardiovascular Fitness 3

Question 1

A client's RPE is 13 on the Borg 6–20 scale during a treadmill test. What approximate percentage of VO2max does this correspond to?

Accepted Answer

65–75%

Answer

An RPE of 13 ('somewhat hard') on the Borg scale corresponds roughly to 65–75% of VO2max in most trained individuals.

Question 2

When prescribing cardiovascular exercise using METs, which daily activity is approximately 3 METs?

Accepted Answer

Slow walking at 2 mph

Answer

Slow walking at approximately 2 mph requires about 2.5–3.0 METs, placing it at a light activity level.

Question 3

According to ACSM guidelines, what is the minimum recommended weekly volume of moderate-intensity cardiovascular exercise for most healthy adults?

Accepted Answer

150 minutes

Answer

ACSM recommends at least 150 minutes per week of moderate-intensity aerobic activity for substantial health benefits in adults.

Question 4

Which test protocol would be most appropriate for a sedentary, apparently healthy 60-year-old beginning a fitness program?

Accepted Answer

Balke-Ware protocol

Answer

The Balke-Ware protocol uses smaller, more gradual increments in workload, making it safer and more appropriate for sedentary or older individuals.

Question 5

Fick's equation for VO2 is expressed as VO2 = cardiac output × a-vO2 difference. If cardiac output doubles and a-vO2 difference increases by 50%, what happens to VO2?

Accepted Answer

Triples

Answer

VO2 = 2Q × 1.5(a-vO2) = 3× the original VO2, so oxygen consumption triples.
