1
Q
what is Cardiovascular drift
A
when there is an increase in HR even tho there is no increase in intensity
cardiac output must be maintained( oxygen leaving heart per minute)
2
Q
why does the HR increase even tho intensity is the same
A
Sv has fallen
3
Q
reasons why SV fall
A
dehydartion
warm weather, humid means sweat
longduration
4
Q
why does SV fall explained in detail
A
through dehydration, reduces blood plasma, increases blood viscioty, increasing resitance to blood flow
causing SV to go down
5
Q
relationship between SV and HR
A
compensate for SV, associated in increasing HR
