CV- Additional Info Flashcards
conversion table
METS
x3.5
relative VO2 (ml/kg/min)
xBW (kg)/1000
absolute VO2 (L/min)
x5
kcal/min
x total number of minutes
total kcal
mesocycle
4-6 weeks
relative intensity (physiologic)
HRR, % HR max, VO2 %
why wouldn’t we be able to prescribe relative intensities with general guidelines
clients taking medications that significantly influence HR
absolute intensity
mph, watts, kgm/min
-not always possible because exercise testing data isn’t readily available
do NOT prescribe absolute intensity unless…
unless it was acquired from testing data
if absolute intensity cannot be prescribed, what do we use
relative intensity
relative intensity (non-physiologic)
RPE, modified RPE, OMNI scale, talk test, counting talk test
when is relative intensity (non-physiologic) used
only if relative (physiologic) or absolute cannot be prescribed
-because it is not nearly as accurate as other relative measures
after stroke volume plateaus, describe HR relationship with VO2
nearly linear
how does HR differ from other absolute measures of intensity
it is autoregulatory
% of HR max or HRR are more accurate
HRR
-because HRR considers resting HR
HRR
preferred relative measure of intensity for CV programs
-always going to be our default for programs
-considers resting HR + autoregulatory nature of HR, which makes it more accurate than other measures
what does HRR look at
how much HR we have left between resting level + maximal level
what should be the 1st option for CV prescriptions
HRR calculated based off GXT results
-paired with proper absolute intensity
when wouldn’t we use HRR
if we have a medication that influences HR
ex: beta blockers
50% HRR = ____ on modified RPE
5
6 on modified RPE = ____% HRR
60%
____ has 1:1 relationship with ____
%HRR has 1:1 relationship with %VO2R
HRR equation
(max HR – resting HR)*desired intensity + resting HR
HR max equation
220 - age
% HR max calculation
max HR x %
1 MET = ____
3.5 ml/kg/min
what does 1 MET signify
resting energy expenditure
-aka energy required for our body to stay alive at rest
MET is absolute/relative measure of intensity
absolute
-unless using as % of client’s maximal ability
moderate intensity in METs
3-6 METs
high intensity in METs
greater than 6 METs
MET-min
how many METs you are training at for the number of minutes you are training at
-METs x min
solve for MET-min:
8 METs for 40 min
240 MET-min
