List 4 negative outcomes that can result from untreated Hypertension
• Pathological cardiac hypertrophy • Formation of cerebral aneurysms • Renal or afferent artery stenosis • Heart failure
a single bout of Aerobic exercise will cause little change to _____ and increase _____
DBP SBP
What level RPE should be attained in strength training to decrease blood pressure
12-13
List what should be included in a health screening before exercise of those with CVD?
• Medical history • physical examination • laboratory assessment (cholesterol) • physiological testing (GXT)
List positive outcomes of exercise in those with CAD
• structural and functional changes in myocardium • reduces heart rate and blood pressure = reduced cardiac workload • reduced anginal pain
What is the most common symptom in PAD
Intermittent Claudication
What should be the focus in exercise for those with PAD
Improve walking capacity
What are risks or special considerations in PAD patients when exercising
• poor wound healing • peripheral neuropathy (balance) • increases bleeding risk • at risk of AAA
How is O2 consumption affected in PVD patients ?
O2 consumption 50% of that in normal individuals
What exercise pattern should be used in PVD
Exercise-> rest and repeat Symptom dependent
Following a single bout of exercise, BP will ______ for _____ hours
Decrease 22 hours
A combination of _____ training and _______ training should be performed by hypertensive patients
Aerobic Weight
List 5 benefits of exercise with COPD
• CV reconditioning • Desensitisation to dsypnea • Increased muscular strength • improved body composition • Improved ventilator efficiency
What should be the 4 goals of exercise for COPD patients
• Optimise respiratory mechanics • Energy conservation during ADLs • Correct physical reconditioning • Desensitisation to dyspnea
Why are warm-ups important for asthma patients
Refractory period
List benefits of exercising for asthma patients
• Increased efficiency of oxygen delivery • less production of lactic acid • decreases ventilation
List 5 ways to reduce risk of EIA
• Monitor air flow with a peak flow meter • Avoid allergic triggers • Take medication before exercise • Warm and up cool down • Nasal breathing
Testing considerations: With individuals of middle age, present HTN and additional Coronary risk factors, what should be done on initial testing and why
Stress test, will show any heart abnormalities
Vasodilatory effects from exercise can be due to what?
• Body warming effects • Lactic acid or Nitric Oxide production • Decreased sympathetic activity • Hormone/receptor response
Why could aerobic exercise be beneficial in HTN patients
It acts quickly to chronically reduce BP Positive effects can be seen in 3 weeks
How does resistance training effect blood pressure, give recommendations
Only has a modest effect 8-12 reps, single set of 8-10 exercises
What should be considered for a warm up with those with hypertension
Slow warm up will reduce the chance of large BP increases
An individual is taking Beta- blockers for their hypertension, why is this important to know ?
HR is no longer a reliable indicator of intensity
Why should exercise be undertaken by those with CVD
• it is shown that exercise can stabilise or regress Atherosclerosis
