Week 5 Flashcards
Aerobic fitness
he ability of the heart, lungs, blood and blood vessels to deliver oxygen and the ability of the muscles to use oxygen for energy
The more “reserve” someone has means what?
→ Reserve = the ability to respond to emergencies or unusual physical demands)
→ The more aerobically fit someone is
In Endocrine system:
Adrenaline:
→ increased HR, increased BP, increased energy
Cortisol:
→ energy efficient, tissue repair
Glucose Regulation:
→ balance insulin and glucagon to be sure energy needs are met
Growth Hormone Release:
→ muscle growth, tissue repair
Acute VS Chronic impact of the CV and Respiratory systems
Acute:
→ more oxygen/HR increases
→ breath faster/need more air
→ stay cool/sweat
→ give energy/adrenaline
→ have fun/endorphins
Chronic:
→ Stronger heart/more efficient CV system and healthier vessels
→ Strong lungs/ more efficient respiratory system
Laboratory tests:
The ideal way to measure aerobic fitness is to have someone exercise on a treadmill or stationary bike, and directly measure VO2 max
Issues with laboratory tests:
→ are expensive to conduct
→ require specific equipment
→ extensively trained personnel
→ higher risk and unnecessary for the majority of people
Field tests
refers to the fact that they are not done in a lab. Field tests are functional ways to test the ability of a client to perform a specific task
- Typically use submaximal protocols
- Estimated maximum rather than exercise to maximum
- More safe in higher risk pops - typically only 85% HRmax
Which is pre-screening and which is health measures?
Pre-screening:
→ GAQ
→ Informed consent
→ AAL-Q
→ PA history
→ SB history
→ Medical history
→ Preliminary instructions
Health Measures:
→ RHR
→ RBP
How to monitor aerobic exercise:
→ HR (max HR method, HRR method)
→ RPE (Borg scale)
→ Talk test
HR MAX
tells us how fast our heart can beat during exercise
HRR
tells us how much our heart rate can increase from resting to maximum during exercise
HR MAX vs HRR
HR MAX: tells us how fast our heart can beat during exercise
HRR: tells us how much our heart rate can increase from resting to maximum during exercise
Reasons to stop an aerobic fitness assessment:
→ client reaches the HR threshold (normally 85% of HR Max)
→ clients chooses to stop for any reason
→ client shows ‘Signs of Intolerance’ or ‘Physiological distress’
Staggering (can’t maintain cadence)
Dizziness, light-headedness
Leg pain, chest pain
Nausea
Facial Pallor (white skin), blue lip
→ Go directly to active recovery at that point
→ If symptoms continue, put client in recovery position and monitor HR and BP
Active recovery
After an aerobic fitness test; allowing your client appropriate recovery is important.
This could include:
→ cool down for 3 – 5 minutes of active recovery by walking slowly or continuing on ergometer with lower intensity (ie slower treadmill speed and no incline)
→ Have client sit down, measure post exercise HR and BP after 1, 3 and if necessary, 5 minutes during recovery and record (Should be <100 bpm and <160/<90)
Match the following:
A - If you have an inability to produce insulin you have…
B - If you are resistant you have
1) T1D
2) T2D
A = 1)
B = 2)
- T/F: An example of a naturally acquired active immunity is becoming exposed and sick with a virus
True
