Dyslipidaemia and exercise Flashcards
Dyslipidaemia – definition, prevalence + rationale • Lipid transport • Pathophysiology – dyslipidaemia and CVD • Pharmacological interventions • Lifestyle interventions • Exercise prescription for individuals with dyslipidaemia
Why is HDL cholesterol more favourably increased after endurance training?
Total cholesterol remained unchanged, although the HDL:LDL cholesterol ratio improved considerably, suggesting that the increased intensity and structure normally associated with aerobic exercise has a more consistent impact upon triglycerides and LDL cholesterol than moderate levels of physical activity
What role might HIIT aerobic training have in improving cholesterol profiles?
Aerobic exercise at high intensities appears to be effective in improving the lipid profile, and the effects surpass those of physical activity by initiating clearance of plasma LDL cholesterol and triglycerides
What %1RM, reps & sets would you prescribe for resistance exercise?
Two sets of 15 repetitions at 60% 1 RM
What is a lipid?
o Organic molecules, poorly soluble in water
o Carbon containing, few oxygen molecules
Why do we need fat?
o Energy
o 80kg male who is 15% body fat: 12.3 kg of fat = 442,000 kJ or 111,000 kcal ~ 44 days without food ~1,300 km of running
Why do we need cholestrol?
o Membrane ‘stiffener’
o Steroids
o Vitamin D
o Bile acids
What is atherosclerosis?
o Foam cells>Fatty streak>Intermediate lesions>Atheroma>Fibrous plaque>Complicated lesions/Rupture/Thrombosis/Occlusion
What is Dislipidaemia?
Elevated blood cholestrol, TAG, or both
What is Hypercholestrolaemia?
Elevated blood cholestrol
What is Hypertriglyceridaemia?
Elevated blood TAG
What is Hyperlipoproteinaemia?
Elevated blood lipoproteins
What is Hyperchylomicronaemia?
Elevated blood chylomicrons
