 Approximately .245 L.min-1
Term
 How high could maximal absolute oxygen consumption be in highly trained aerobic athletes?
Definition
 5.5L.min-1
Term
 Why is absolute oxygen consumption useful?
Definition
 Because it allows for an estimation of caloric expenditure.

 5 (or 20.9 kilojoules)
Term
 What is relative oxygen consumption?
Definition
 The rate of oxygen consumption relative to body weight measured in mL.kg-1..min-1In other words, it is the volume of oxygen consumed per kilogram of body weight every minute.

 What is the formula to calculate VO2 when doing leg ergometry?
Definition
 VO2 = (10.8xWxM to the -1)+7W= wattsM= mass
Term
 What is the formula to calculate VO2 when doing arm ergometry?
Definition
 VO2 = (18.W.M to the -1) + 3.5

 What is the formula to calculate VO2 when stepping?
Definition
 VO2 = (.2xf)x(1.33x1.8xHxf) + 3.5f=frequency of steps H=step height in meters.
Term
 What is a MET?
Definition
 1 met equals resting relative oxygen consumption (which is 3.5mL.kg-1.min-1)
Term
 How is a MET calculated?
Definition
 By dividing relative oxygen consumption by 3.5
Term
 How is Gross VO2 calculated?
Definition
 the sum of the oxygen cost of physical activity and the resting component.
Term
 How is net VO2 calculated?
Definition
 net VO2=gross VO2 - resting VO2
Term
 Note:
Definition
 Know how to fill in the chart on page 218
Term
 How do you calculate the absolute oxygen consumption equivalent to 10 METs for a 154lb male?
Definition
 Multiply MET value by 3.5 to convert METs to relative VO2, then multply the product (35mL.kg-1.min-1) by body weight in kg (154=70KG)
Term
 What is the equivalent total caloric expenditure of 2.5 lb of body weight?
Definition
 multiply 2.5 x 3500. 8,750kcal
Term
 A 70 kg male expends 7.5 kcal/min while exercising. What is the equivalent MET value?
Definition
 1500mL/min / 70kg = 21.4mL/m21.4mL/min / 3.5 = 6.1 METS
Term
 Using the ACSM walking formula, you calculate gross VO2 of 13.0mL.kg-1.min-1. What is the net oxygen uptake?
Definition
 Just resting from gross. It equals 9.5
Term
 Convert the following values to the desired units.1.5 m to cm59.1 in to m70 kg to lbs6.0 mph to meters per minute50 RPM on the Monark leg ergometer to meters per minute.
Definition
 1500 cm59 x 0.0254 = 1.5m154 lbs6.0 x 26.8 = 160.8m/min50RPM x 6 = 300m/min
Term
 What are practical uses for the ACSM metabolic energy expenditure formulae
Definition
 It allows for an estimate of the energy expenditure and caloric expenditure associated w/ exercise.It will also allow the health/fitness professional to develop more effective exercise prescriptions.
Term
 memorize chart on pg 220
Definition
 n/m
Term
 What speeds do the walking formula apply to?
Definition
 50 to 100 m/min or 1.9 to 3.7 mph

 Grade of the treadmill multiplied by speed of the treadmill multiplied by 1.8
Term
 What speeds do the running formula apply to?
Definition
 anything above 134m/min (5mph)
Term
 How do you calculate METs when running horizontally on a treadmill?
Definition
 speed in m/min x .2
Term
 How do you calculate METs when running on an incline?
Definition
 Speed of treadmill in m/min x .9 x functional grade.
Term
 What is work rate also known as?
Definition
 power output or workload.
Term
 How is work rate calculated on a cycle ergometer?
Definition
 work rate = force x velocity
