ACSM-EP Metabolic Calculations

Question 1

A client walks on a level treadmill at 2.5 mph. Using the ACSM walking equation, what is the estimated VO2 in mL/kg/min?

Accepted Answer

10.2

Answer

2.5 mph = 67 m/min, so VO2 = 0.1(67) + 3.5 = 10.2 mL/kg/min.

Question 2

A client runs on a level treadmill at 6.0 mph. Using the ACSM running equation, what is the estimated intensity in METs?

Accepted Answer

10.2

Answer

6.0 mph = 160.8 m/min; VO2 = 0.2(160.8) + 3.5 = 35.7 mL/kg/min, which is 10.2 METs.

Question 3

An 80 kg client cycles on a leg ergometer at 100 W. Using the ACSM leg cycling equation, what is the estimated VO2 in mL/kg/min?

Accepted Answer

20.5

Answer

100 W = 600 kg-m/min; VO2 = 1.8(600)/80 + 7 = 20.5 mL/kg/min.

Question 4

How many kilocalories does a 75 kg client expend during 30 minutes of exercise at 8 METs?

Accepted Answer

315

Answer

kcal/min = 8 x 3.5 x 75 / 200 = 10.5, and 10.5 x 30 = 315 kcal.

Question 5

An 80 kg man has an absolute VO2 of 2.8 L/min during a graded exercise test. What is his relative VO2 in mL/kg/min?

Accepted Answer

35.0

Answer

Relative VO2 = 2800 mL/min / 80 kg = 35.0 mL/kg/min (10 METs).
