KINES 484 Exam 1
Terms in this set (38)
What is heart rate variability?
The body's ability to adapt to meet the physical demands of exercise.
This increases with exercise.
WE WANT THIS TO HAPPEN.
Defining pathophysiological features of coronary artery disease (CAD)
Endothelial dysfunction: Cells are fast & responsive, this causes decreased vasodilation & healing.
-Aerobic exercises improves and heals this
Chronic Inflammation: Cells are no longer responding in vascular system.
-LDL's are attracted, they attach and form plaque (atheroma)
Decrease lumen size: Blocks blood flow which causes ischemia to heart muscles.
Heart Rate Variability is phenomenon which
Considered + trait within autonomic nervous systems (ANS) adaptability. Increases with exercise program.
Best warm-up for PAD when using treadmill
NO exercise when RESTING BP is
Which condition was not highlighted as having increased risk for inflammation with exercise?
Peripheral Artery Disease (PAD)
Inflammation and Exercise
Necessary to make improvements,
Trains body to create more internal antioxidants,
Causes oxidative stress
What are signaling molecules that are like hormones?
What is lumen?
The inside space of the vessel
Etiology of COPD is ____________ & initiates the destruction of tissue through ________.
Toxins; chronic inflammatory chemicals
Strongest influence on surviving a heart attack?
One unique exercise parameter with PAD
Push client to experience symptoms during aerobic exercise.
How do free radicals damage tissue?
Bring inflammation to area,
Change molecule's structure & function,
Steal an electron
Risk factor for CAD
HDL of 24
Stress test clearance as females with hypertension or atherosclerosis
Substance gets oxidized & attaches to artery walls & forms plaque
Best effects of exercise training for CAD/PAD
Growing vessels in area of blocked arteries.
Have increased risk of inflammation with exercise?
Elderly, obese children, & diabetes.
How does exercise combat chronic inflammation when balance is correct?
Restoring balance in system's chemical process
What is most dangerous in the heart?
Smaller and unstable arterial wall.
Effect of exercise on vascular conditions
Increase regenerations of endothelial cells,
Decrease vascular inflammation,
Increase enzymes to break up blood clots,
Increase in HDLs
Abnormal response that's expected with hypertension
Decreased heart rate variability,
Decreased cardiac output,
Reduction in aerobic capacity
2 occasions where heart attack patients may become HYPOtensive during exercise?
Warm-up/Cool-down & changing from supine to standing.
Avoid when PAD client is experiencing symptoms during exercise
Painful cramping in chest because of ischemia
Respiratory rate over 20 breaths per minute
Hardening/scarring of tissue
How long will PAD client experience pain during intense endurance exercise?
Substances found in chronic inflammation
Pro inflammatory cytokines,
Best way to physiologically change vessels for thick cap
COPD heart rate will be ______ compared to healthy clients.
CAD clients wants to do high weight & low reps. Safe? Why or why not? 3 specific essential lifting teachings?
Why: Can't adjust to the demand of workout, Increase weight increase change of Valsalva which is not good for them.
3 specific lifting techniques
-Avoid high weight with low reps
-Don't go from supine to standing
Primary etiology of hypertension in US
Idiopathic & obesity
How long can effects of a single aerobic exercise last?
Why do you need to supervise a cool-down with hypertensive clients?
Post exertional hypotension is very common. Need to monitor heart rate as client comes down from exercise session.
List specific prognosis exercise index used for COPD & how exercise influences factors.
Use peak flow os spirometer.
Peak flow measures lung capacity.
-if patient is <50% of base line—> NO EXERCISE
-If 60-80% of baseline—> Use inhaler/medication before & during exercise
Pink Puffers: Condition, Damaged, S&S, Positions
Damaged structure: Alveoli
S&S: Barrel chest, pursed lips, scrunched shoulders (tight scalenes)
Avoid position: Arms overhead
How do you make clients with exercise induced asthma feel safe during start of new program?
-Have prolonged warm-up/cool-downs
-Decrease environmental triggers
-Tools to teach difference between exercise and breathlessness from condition
—-Peak Expiratory Flow
—-Modified Borg Dyspnea Scale
-Stay at 60% intensity for 6 weeks
