Front (Question)

Anaerobic metabolism does or does not require oxygen -uses what -occurs where -yields how many ATP

Back (Answer)

does not require oxygen utilizes only carbohydrates (glucose) occurs in the cytoplasm yields 2 ATP molecules per glucose molecule

Front (Question)

aerobic metabolism does or does not require oxygen -uses what as fuel -occurs where -yields how many ATP

Back (Answer)

does require oxygen utilizes carbohydrates, fats and proteins occurs in the mitochondria yields about 36 ATP per molecule of glucose

Front (Question)

anaerobic metabolism yields how many molecules of ATP

Back (Answer)

2 ATP

Front (Question)

aerobic metabolism yields how many molecules of APT

Back (Answer)

36 ATP

Front (Question)

Heart CNS, PNS skeletal muscle slow twitch fibers are all what types of cells

Back (Answer)

aerobic

Front (Question)

connective tissue cells (bone, cartilage, RBC) skeletal muscle fast twitch muscles are all what types of cells

Back (Answer)

anaerobic

Front (Question)

What is the gold standard measure for evaluating a person while performing work?

Back (Answer)

oxygen consumption- VO2

Front (Question)

What are the equations for measuring VO2

Back (Answer)

VO2= CO x a-v O2 difference—invasive VO2=volume of O2 entering the lungs mins volume of O2 leaving the lungs—not invasive use equipment

Front (Question)

Not capable of performing work soley aerobically Switch from aerobic to anaerobic

Back (Answer)

anaerobic threshold

#10

Front (Question)

When does a typical person reach their anaerobic threshold?

Back (Answer)

55% of a person max VO2

#11

Front (Question)

Can anaerobic threshold change with training?

Back (Answer)

yes increased percentage with training or decrease with detraining

#12

Front (Question)

Clinically when can you tell someone has reached their anaerobic threshold?

Back (Answer)

occurs when exercising and the person is having difficulty talking to another person becomes breathless

#13

Front (Question)

what is the percentage of oxygen in the air? what is the percentage of oxygen that is expired?

Back (Answer)

O2 in air- 21% O2 expired- 4%

#14

Front (Question)

What is the problem with measuring VO2 using the equation VO2=volume of O2 entering/volume of CO2 leaving

Back (Answer)

does NOT take into consideration persons body weight

#15

Front (Question)

what is MET in relation to VO2

Back (Answer)

1 MET = the energy (oxygen) used by the body as you sit quietly, perhaps while talking on the phone or using the phone 1 MET= 3.5 mLO2/kg * min

#16

Front (Question)

Any activity that burns 3-6 METs is considered a ______activity

Back (Answer)

moderate intensity

#17

Front (Question)

any activity that burns >6 METs is considered a ______ activity

Back (Answer)

vigorous intensity

#18

Front (Question)

if a person has an AT that is 22 mlO2/kg*min and is asked to do a 3 MET activity is that above or below their AT

Back (Answer)

below pt should not be breathless 3 METs x 3.5 mlO2/kg* min = 10.5 mlO2/min

#19

Front (Question)

if a person has an AT of 8 mlo2/kg*min and they are asked to perform a 3 met activity is that above or below their AT

Back (Answer)

yes above pt will be breathless 3 METs x 3.5 mlO2/kg*min= 10.5

#20

Front (Question)

what are factors that affect peak VO2 (6)

Back (Answer)

age sex genetics body composition endurance training various diseases that affect oxygen transport (COPD)

#21

Front (Question)

Social security administration uses the criteria that <18mL/kg*min (or ~5 METs) is considered _____

Back (Answer)

disabled
