Disease Linked To Exercise Flashcards
What are the three types of strokes
Ischaemic stroke
Haemorrhagic stroke
ITA stroke
What is a ischaemic stroke
An ischaemic stroke is caused by a blockage that prevents O2 from reaching the brain
What is a Haemorrhagic stroke
A haemorrhagic stroke is one where there is a bleed in or around the brain
What is an ITA stroke
An ITA stroke is a mini ischaemic stroke where symptoms last for less that 24 hours and caused by a temporary blockage
Define sedentary lifestyle
A sedentary lifestyle is an inactive lifestyle
Define atherosclerosis
Atherosclerosis is a condition where fatty plaque builds up in the artery walls causing them to narrow and their lumen to narrow
Define CHD
CHD is a condition where fatty plaque builds up in the coronary arteries walls causing the lumen to narrow and a reduction in blood flow to the cardiac muscle
Define coronary arteries
Coronary arteries are arteries that supply oxygenated blood to the cardiac muscle
Define angina
Angina is a condition where there is a partial blockage in a coronary artery causing chest pain due to a lack of O2 to the cardiac muscle
Define heart attack
Heart attack is where there is a complete blockage in a coronary artery causing restriction of O2 to the cardiac muscle
Define coronary risk factors
Coronary risk factors are conditions or habits that increase the risk of a heart attack and are lifestyle choices
Name 3 examples of coronary risk factors
- Obesity
- Smoking
- High LDL cholesterol diet
- Hypertension
Define hypertension
Hypertension is where you have abnormally high blood pressure
Define stroke
A stroke is where the O2 supply is cut off from the brain
Define LDL cholesterol
LDL cholesterol (low density lipoprotein) builds up as fatty plaque in the blood vessels
Define HDL cholesterol
HDL cholesterol (high density lipoprotein) reduces levels of LDL in the blood and clears artery walls of the fatty plaque
How does cardiac hypertrophy reduce the risk of CV disease (3 things)
- Reduce resting HR
- Increase SV
- Decrease CV strain
How has any increased efficiency of coronary arteries helped prevent CV diseases
Increasing efficiency means more blood can be delivered to the cardiac muscle / min
Name 3 ways in which increases elasticity of arteries has reduced the risk of getting a CV disease
- Reduced blood pressure
- Widstand a higher blood pressure
- More efficient vascular shunt mechanism
Name 2 adaptations that make the blood resistance to a CV disease
- Decreases LDL and increases HDL so fatty plaque in arteries is reduced
- Decreased blood viscosity, increases blood pressure and so decreases blood pressure
How other factor caused by exercise has reduced the risk of a CV disease
Bodyweight management and a healthy energy balance
What are the two respiratory diseases you need to know
- Asthma
2. Chronic obstructive pulmonary disease (COPD)
Name 3 symptoms of asthma
- Shortness of breath
- Coughing
- Wheezing
- Tight chest
Name 3 triggers of asthma
- Exercise induced asthma
- Pollen
- Pollution
Name 3 measures of asthma control
- Exercise
- Healthy diet
- Inhalers
Define asthma
The reversible narrowing of respiratory airways causing inflammation and increasing mucus production
Define respiratory muscle training
Breathing exercises to increase the strength and endurance of respiratory muscles normally aimed at people who suffer from asthma and COPD
Define COPD
COPD is a group of lung conditions that make it hard to hard to empty air from the lungs because the airways have been narrowed (long term health condition)
Name 3 symptoms of COPD
- Shortness of breath
- Ongoing Cough that produces a lot of mucus
- Wheezing
- Chest pain
Name 3 causes of COPD
- Smoking
- Decreased elasticity of airways
- Permanent airway narrowing
Name 2 treatments of COPD
- Medication
2. Exercise
Name 2 ways how respiratory structures are adapted by exercise to reduce the chance of RS disease
- Increase SA and elasticity of alveoli so increased TV
2. Capillerisation around alveoli so increased diffusion of gases
Name 2 ways in which the mechanics of breathing have adapted due to exercise to reduce the chance of a RS disease
- Increased strength and endurance of respiratory muscles so more efficient and increased TV
- Delayed respiratory fatigue
