Landin, MS, ATC Oxygen is needed to convert carbohydrates and fats into energy for the body's use Also used to enable the body to perform physical tasks Cycle: Inhale oxygen travels into alveoli absorbed into blood stream travels to muscles, organs and brain carbon dioxide into blood stream taken out of blood stream at alveoli exhale Cardiorespiratory Endurance Also called aerobic fitness Determined by maximal oxygen uptake or VO2max Maximum amount of oxygen the body is able to utilized per minute of physical activity measured in L/min. or mL/kg of body weight/min. The higher the oxygen consumption, the more efficient the cardiorespiratory system is Absolute Oxygen Uptake Determining the caloric expenditure of physical activity Determined by a direct gas analysis during an aerobics test (pg. 29 picture) 5 kcal burned/1 L of Oxygen consumed Oxygen consumption at 0.3 to 0.5 L/min. during rest 5 L/min. oxygen consumption during maximal exercise Typical person exercises at 60% capacity Example to determine absolute oxygen uptake Person with 3.5 L/min. oxygen uptake Works out at 60% of maximum HR (3.5 x .60)=2.1 L of oxygen consumed/min. of physical activity (2.1 L x 5 kcal/L)=10.5 kcal/min. burned at that exercise pace (10.5 x 30 min.)=315 kcal burned in a 30 minute workout at that exercise pace 1 lb. of body fat = 3,500 kcal Testing Cardiorespiratory Endurance 1.5 mile run test 1.0 mile walk test (pg. 30 equation) Step test ...

    The ability to access any university’s resources through Course Hero proved invaluable in my case. I was behind on Tulane coursework and actually used UCLA’s materials to help me move forward and get everything together on time.
