Exercise Metabolic Equations

Walking, Running, Leg Cycling, Arm Cycling and Stepping

Exercise Metabolic Walking Equations

VO2= 3.5+0.1(speed)+1.8(speed)(fractional grade)

Exercise Metabolic Running Equation

VO2= 3.5+0.2(speed)+0.9(speed)(fractional grade)

Exercise Metabolic Leg Cycling Equation

VO2= 7+1.8(work rate)/(body mass)

Exercise Metabolic Arm Cycling Equations

VO2= 3.5+3(work rate)/(body mass)

Exercise Metabolic Stepping Equations

VO2= 3.5+0.2(stepping rate)+2.4(stepping rate)(step height)

Functions of Metabolic Equations

1. Use them to calculate oxygen consumption and ultimately energy expenditure of a

specific exercise



2. Can use the equations to calculate the target workload in an exercise prescription

, Functions of Metabolic Equations

1. Use them to calculate oxygen consumption and ultimately energy expenditure

of a specific exercise

Important for telling your clients how many calories they are burning during an exercise

session

Functions of Metabolic Equations

2. Can use the equations to calculate the target workload in an exercise

prescription

Allows you to give your clients a specific speed to work on a bike or a treadmill if HR is

difficult to measure

Approach to solving metabolic equations

1. Convert any raw data into the units as they appear in the equations

2. Solve the equation using basic algebra

3. Convert the answer to desired units

(See page 52)

Measures of Intensity

Heart Rate Reserve

(% of difference between resting and maximal HR)



Formula: Target HR=[(HRmax-HRrest) X % intensity] +HRrest
