Exercise and Chronic Conditions (Slides 21-42) Flashcards
BP rises quite a bit during resistance exercise, but does chronic resistance training cause elevated BP?
Nope! Chronic resistance training doesn’t elevate resting BP - Resistance training actually reduces typical short-term BP increases
Can resistance exercise be used to lower BP in hypertensive individuals?
Yes - it shouldn’t be used as the sole exercise mode though
Heart disease pathogenesis progresses in what 5 stages?
- Injury to endothelial cell wall of coronary artery
- Fibroblastic proliferation of inner artery lining
- Further obstruction of blood flow as fat accumulates
- Cellular degeneration and subsequent formation of hyalin within arterial intima
- Calcium deposition at edges of hyalinated area
Athersclerosis appears on chromosome __ and accounts for nearly __% of all cases of CHD. How is it expressed?
19; 50%
Abdominal obesity, low LDH, high LDL
Angina Pectoris: Chest pain occurs in __% of initial manifestations of CHD - what does this indicate?
1/3 of those experiencing recurring angina die suddenly from what?
30%; inadequate coronary blood flow
myocardial infarction
___ ___ occurs from sudden insufficiency in myocardial blood flow, usually from coronary artery occlusion - severe fatigue is usually experienced for several days preceding an incident
Myocardial Infarction (MI)
What is congestive heart failure (CHF)?
when the heart fails to pump adequately to meet needs
What are the primary causes of CHF?
- Narrowed arteries from CHD
- Past MI with necrosis
- Chronic hypertension
- Heart valve disease from past rheumatic fever
- Intrinsic myocardial disease
- Cardiomyopathy
- Congenital defects
- Infected heart valves
CHF treatment and rehabilitation?
Regular PA during rehabilitation
PA guidelines for CHF treatment?
Intensity: 40-60% VO2 peak or light to somewhat hard based on RPE
Duration: can increase 20-40 min 3x/wk - after 6-12 wks, patients can undertake an unsupervised home program
For CHF patients who contract before age 60, about __% die within 1 year of diagnosis and nearly __ die within 5 years
20%; half
6 warning symptoms of cardiac decompensation?
- Dyspnea
- Hypo-tension
- Cough
- Angina
- Lightheaded
- Arrhythmia
Heart valve diseases include? (3) What do these cause?
- Stenosis (narrowing/constriction)
- Insufficiency (closes improper - blood comes back in)
- Prolapse (enlarged valve bulges back into L atrium)
Heart’s workload increases
Cardiac diseases that affect heart’s electrical conduction system include?
Dysrhythmias that cause heart to beat irregularly:
- tachycardia
- bradycardia
- ectopic, extrasystole
- premature ventricular contraction
Why is it important to ensure proper health screening occurs before initiating exercise intervention?
To ensure that the person is medically safe to exercise!
