!!! Impact of training on lifestyle diseases

Question 1

What are the cardiovascular diseases?

Answer 1

1. Atherosclerosis, a build up of fatty deposits on arterial wall, leading eventually to chronic high blood pressure
2. Coronary heart disease, the reduction of blood flow and O2 to the cardiac muscle can ultimately lead to heart attack
3. Heart attack, a blockage in the coronary artery cuts off O2 supply to the cardiac muscle, causing the death of cells or permanent damage
4. Stroke, caused by a blockage in a cerebral artery cutting off blood supply to the brain

Question 2

What are the effects of training on cardiovascular disease?

Answer 2

1. Reduced blood lipids and cholesterol and increase the proportion of HDL to LDL cholesterol
2. Prevention of the hardening and loss of elasticity in arterial walls, slowing onset of atherosclerosis
3. Decrease blood viscosity, preventing blood clots and reducing BP
4. Increase coronary circulation
5. Lead to cardiac hypertrophy, increased SV and lowered resting HR
6. Increase blood flow and O2 transport, reducing strain on the heart

Question 3

What are the respiratory diseases?

Answer 3

1. Asthma, the constriction of the bronchial airways and the inflammation of the mucus membranes, which limit breathing
2. Chronic obstructive pulmonary disease, condition of the lungs where airways become inflamed and narrowed, over time the inflammation causes permanent changes and can lead to an inability to exercise

Question 4

What are the effects of training on respiratory disease?

Answer 4

1. Increased respiratory muscle strength, alleviating symptoms of asthma
2. Decreased resting and submaximal breathing rate
3. Increased airflow
4. Maintained use of lung tissue and elasticity, decreasing the risk of infection
5. Increased surface area of the alveoli, maximising gaseous exchange
