1 MET equals
3.5 ml/kg/min
power equation
power (w)= work (J) / time (sec)
work equation
work (J)= force (N) x distance (m)
Kcal*min
1 L O2 = 5kcal * L
which muscle fiber is more efficient
type 1 skeletal muscle
walking VO2 metabolic calculation
(0.1 * speed) + (1.8 * Speed * Grade) + 3.5
running VO2 metabolic calculation
(0.2speed) + (0.9 * SpeedGrade) +3.5
for running vo2 metabolic calculation, what happens if surface is flat
you dont add vertical grade to equation
Direct calorimetry measures
heat
indirect calorimetry measures
heat
CO2 production
oxygen consumption
Absolute VO2 equation
L * min
relative VO2 equation
mlkgmin
how to convert relative vo2 to absolute vo2
relative vo2(ml/kg/min) * body weight (kg) / 1000
how to convert L to mL
*1000
how to convert mL to L
divide 1000
% grade of sub max test
85%
what % of air is oxygen
21%
which is more useful for comparing individuals’ VO2
relative vo2 because of body weight
for cycle ergometry, how much is 1 revolution?
6m
to calculate work for cycle ergometry, what is the force
resistance that you add
vertical displacement equation
% grade * distance
work equation for treadmill output
force- body weight
distance- total vertical displacement
how to get percent into a decimal
divide 100
work equation for bench step output
force- body weight
distance- height of step, how many steps, and how long
