What is the bodys maximal oxygen consumption?
What is oxygen consumption influenced by?
What is the ability to work for prolonged periods of time and ability to resist fatigue?
What is the ability to perform repeated contractions of a specific m. group over a period of time?
What is the ability to perform large muscle exercise for long periods of time?
What is aerobic exercise training?
- exers program to improve the energy capacity of a m.
- exers must be sufficient intensity, duration, and frequency
How long does it take to see significant changes in aerobic programs?
What is adaptation of aerobic exers dependant on?
- ability of organism to change
- training stimulus threshold
What occurs with prolonged bed rest or extended illness?
Why does the body adjust circulation during exers?
- increase O2 and nutrients
- remove carbon dioxide and lactic acid
- dissipate excessive heat
What is the rate a conditioning response occurs at? (HR)
70-85% of max HR
How do you determine ones HR using the Karnovens formula?
- young n healthy= 220-age
- exercise HR= HR(at rest) + 60-70%(max HR- rest HR)
older at risk or with coronary artery disease may be as low as 40-60% of their max HR
Who developed the rate of perceived exertion (RPE) scale?
Using the RPE scale, what is considered very, very light exers?
Using the RPE scale what is considered very light?
Using the RPE scale, what is considered fairly light exers?
Using the RPE scale, what is considered somewhat hard exers?
Using the RPE scale, what is considered hard?
Using the RPE scale, what is considered very hard?
Using the RPE scale, what is considered very very hard?
What artery is ant. to the SCM?
What artery is midwat between the elbow and shoulder on the medial arm?
Where is the radial pulse?
wrist, lateral to the carpi radialis tendon
Where is the ulnar pulse?
between flexor digitorum superficialis and flexor carpi ulnaris
What is the amt of blood pumped out of the heart per minute?
What is stroke volume?
amt of blood ejected by the ventricle during contraction
What is the blood volume of adults?
7-8% of bodyweight
What is the MET (metabolic equivalents)?
amt of oxygen consumed per kilogram of bodyweight per minute to perform a given activity
normal at rest= 3.5ml/kg/minute
