  • Impact Of Training On Lifestyle Diseases
    • Stroke
      • A stroke is caused by either a blockage in a cereal artery cutting off the blood supply to the brain or a blood bursting within or on the surface of the brain.
    • Atherosclerosis
      • The build-up of fatty deposits that from a hard plaque on the arterial walls.
        • This progressively narrows the lumen, reduces the space for blood flow and increases the likelihood of blood clots forming.
        • Arterial walls become thick and hardened, reducing their ability to vasodilate and vasoconstrictto regulate blood pressure.
        • Overtime, chronic high blood pressure known as hypertension can develop, which is often the first indicator of this disease.
    • Heart Attack
      • If a piece of fatty plaque breaks away from an arterial wall, a blood clot may form.
        • If the clot suddenly, severely, or totally blocks a coronary artery, it will cut off oxygen supply to an area of the cardiac muscle causing death of cells and permanent damage.
    • Coronary Heart Disease
      • Results from atherosclerosis of the coronary arteries, which supply the heart muscle with oxygenated blood.
        • The reduction in blood flow and oxygen supply limits the cardiac muscle's ability to respire and an angina or heart attack may occur.
    • The Effects Of Training
      • Regular Training Can:
        • Increase coronary circulation as coronary arterioles gain an increased diameter and density.
        • Lead to cardiac hypertrophy, increased ventricular contractility and stroke volume.
          • Which increases the efficiency of the heart, resting heart rate can lower and the strain on the heart is reduced.
        • Decrease blood viscosity and the resistance to blood flow.
        • Decrease body fat and help to manage weight
        • Prevent the hardening and loss of elasticity in the arterial walls due to regular vasoconstriction and dilation.
        • Increase blood flow and oxygen transportation to muscle cells.
        • Reduce the levels of blood lipids and overall cholesterol and increase the proportion of HDL to LDL cholesterol.
        • Reduce the risk of a stroke by 27% by lowering blood pressure and maintaining a healthy weight.
