SET WITH DETAILED ANSWER KEY
◉Cardiovascular disease. Answer: • Coronary heart disease (heart
attack)
• Cerebrovascular disease (Stroke)
• Elevated blood pressure
• Peripheral Artery disease (problems with blood flow)
• Rheumatic heart disease (heart valve damage)
• Congenital heart disease (heart defects)
◉Meta-analysis: PA and stroke prevention. Answer: • Recruited a
large sample of people
• Measured variables
• Measured the outcomes
• Found that moderately active individuals had 20% lower risk of
sufferin from stroke than low-active individuals
• Found that highly active individuals had 27% lower risk of
suffering from a stroke than low-active individuals
,◉PA and CVD Recovery study. Answer: • Recruited 124 patients who
had had a heart attack
• Randomly assigned patients to two conditions
• Condition 1: Exercise 3 times a week for 12 months
• Condition 2: no formal exercise program
◉PA and CVD Recovery study: Results. Answer: Controls:
- 21% of people returned to work within 3 months
- 27% of people returned to work after 6 months
- 22% of people experienced Reinfarction
- 68% of people experienced Angina
Exercisers:
- 55% of people returned to work within 3 months
- 8% of people experienced Reinfarction
- 35% of people experienced chest pain
◉Risk Factors of Cardiovascular disease. Answer: • Elevated blood
pressure
• Poor lipid and lipoprotein profiles
• Low cardiorespiratory fitness
• High body fat levels
,• Metabolic syndrome
◉metabolic syndrome. Answer: • Abnormal levels of lipid and
lipoproteins
• Elevated glucose and insulin levels
• Hypertension
• Excess abdominal obesity
◉diabetes mellitus. Answer: • Low levels of insulin production
• Difficulty maintaining glucose homeostasis
• Type 1-the immune system attacks and destroys insulin producing
cells (most rare and usual seen in young people)
• Type 2- Related to overweight and obesity and insulin resistance
so the pancreas is not able to secrete enough insulin
◉How will physical activity reduce the risks of CVD. Answer: •
Lower heart rate
• Lower blood pressure
• Muscles used for breathing because less fatigued
◉Fick equation. Answer: Central and Peripheral components of the
cardiorespiratory system
, It determines the rate at which a person uses oxygen in their body
aka volume oxygen uptake
◉How much exercise should we get a day?. Answer: Children and
adolescents should get around 60 minutes of physical activity a day
Adults should have at least 150 minutes a week of moderate
intensity and 75 minutes a week of vigorous intensity
◉Obesity. Answer: Having an unhealthy body weight, which is
consistent with a variety of disease processes such as CVD,
metabolic syndrome and type 2 diabetes
◉What percentage of Canadians are obese?. Answer: • 17% of
Canadians are obese
◉BMI. Answer: • Measured typically with BMI: A BMI of 30 or higher
= Obese
• BMI: Body mass index. Weight/Height²
• Advantage of BMI: Only need person's height and weight
• Disadvantage people over estimate their height and underestimate
their weight
◉DREW study. Answer: - What did they do - "Dose-Response to
exercise in postmenopausal women"
