Cardiorespiratory Fitness Flashcards
(39 cards)
As a PT, is a preparticipation screen prior to exercise necessary?
yes
What are modifiable CVD risk factors?
- physical inactivity
- hypertension
- high cholesterol
- diabetes
- smoking
- obesity/overweight
WE CAN INFLUENCE THESE!
What are emerging CVD risk factors?
- nutrition
- alcohol
- stress
What are major CVD risk factors?
- age
- male gender
- family history
- race (non-white)
An increased cardiorespiratory fitness level, ____________ CVD risk.
decreases
What are heart attack symptoms in men?
- nausea or vomiting
- jaw, neck or back pain
- squeezing chest pressure or pain
- shortness of breath
What are heart attack symptoms in women?
- nausea or vomiting
- jaw, neck or upper back pain
- chest pain (BUT NOT ALWAYS)
- pain or pressure in LOWER CHEST or UPPER ABDOMEN
- shortness of breath
- fainting
- indigestion
- extreme fatigue
What is the acronym for a stroke?
B alance difficulties
E yesight changes
F acial weakness
A rm weakness
S peech difficulties
T ime
What energy systems are used during anaerobic exercise?
ATP-PC & anaerobic glycolysis
How long is anaerobic exercise?
30 to 90 seconds
QUICK AND FAST!
What energy systems are used during aerobic exercise?
oxidative
How long is aerobic exercise?
> 2 minutes
LONG AND SLOW(ER)!
Maximal Aerobic Capacity (VO2max or aerobic endurance)
maximum amount of O2 that can be taken in and utilized during exercise
Lactate (anaerobic) threshold
%VO2max in which blood lactate levels begin to rise
In trained individuals, what percent of HRmax is their lactate threshold?
85-90%
Maximal Lactate Steady State
lactate production = lactate clearance
What is the best indicator of aerobic performance?
maximal lactate steady state
What are contraindications to exercise?
- resting HR > 100 or < 50 bpm
- resting SBP > 200 or < 90 mmHg
- resting DBP > 110 mmHg
- oxygen saturation < 90%
- shortness of breath, angina, severe headache, sudden onset of numbness or weakness, painful calf (DVT)
What are signs that you should STOP exercise immediately>
- angina
- drop in SBP below baseline
- signs of poor perfusion: light headedness, confusion, ataxia, pallor, cyanosis, nausea, cold/clammy skin
- failure of HR to rise as intensity of exercise increases
- change in heart rhythm
What increases the risk of cardiac event?
- age
- exercise intensity
- CVD
- exertional symptoms
- decreased fitness
How can you reduce cardiac events?
- teach patients sign/symptoms
- screen prior to participation
- have a plan in place (AED)
START LOW & GO SLOW!
What is the criteria for a true VO2max?
- plateau in VO2 despite increased work rate
- RER > 1.15
- within 10 bpm of age-predicted HR
- RPE > 17 (on 6 to 20 scale)
What is considered a peak VO2max?
when an individual gives it all they got, but they didn’t meet any of the criteria for a true VO2max
What is the goal for a submaximal test?
determine HR response to submaximal work rates & predict VO2max
