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.

what are some standard tests and measures to use
HR, BP, BMI, RR, body composition
28
what are some indications f doing cardiorespiratory testing (7)
assess their current status, develop an exercise plan, provide information to educate the patient (only exercise to an RPE of 8) and motivate them, and give feedback on their training program, evaluate for disease, ID limitations (MSK for a training program)

true
60
what is the most frequently used method for prescribing aerobic exercise intensity
HR
61
intensity can be set at a range of either...
