Q

what is the FICK equation

A

you get O2 coming into the body, into the pulmonary system, then into the systemic, then it is consumed by muscles, and you have CO2 being expelled at the same time.

Q

what happens to a-VO2 as we exercise?

A

exercise, we take more O2 our of the blood, so the difference between the O2 content in the arterial vs venous systems increases, meaning more O2 is taken our of the blood as we have a higher demand for exercise. We have less O2 at the capillary level.

long, slow distance training

83
Q

who is the LSD training program reccomended for, and what are some features

A

for marathon runners. You run longer, but maybe at a slower pace one of your training days.

84
Q

what adaptations do you get from an LSD program

A

enhanced O2 delivery to muscles
clear lactate faster
shift from type IIx to type I fibers
increased use of fat stores, more energy per gram.

85
