GCSE PE - Effects of exercise

  1. 1. Year 11 GCSE PE Edexcel- Presentation By Haleema.B– Heartlands Academy
  2. 2. i) Immediate effects More muscle contractions,Increased blood flow to the muscles, Rise in muscle/body temperature,
  3. 3. Long-term effects Muscular endurance improves, Muscles get bigger (hypertrophies), ... Tendons and ligaments get bigger, Increase in bone density and width,Joints are more stable with increasedflexibility.
  4. 4. ii) Immediate effects Blood temperature rises, Blood vessels near the skin open to allow heatto be lost (vasodilation), Blood shunting occurs (diverted from digestivesystems to the muscles), Increase in heart rate and increase in strokevolume. Therefore, increase in cardiac output.
  5. 5. Long term effects Increased volume of blood (red blood cells), Increased number of capillaries in muscles, Heart gets bigger and stronger (hypertrophies), Maximum cardiac output increases, Quicker recovery rate, Lower resting heart rate, Reduced risk of heart disease,
  6. 6. iii) Immediate effects Increase in breathing rate, Increase in tidal volume, Contraction and relaxation of thediaphragm, intercostal muscles, and ribs(chest) expand+ relaxing,
  7. 7. Long-term effects More efficient gaseous exchange, Increase in vital capacity, Increased number of alveoli, Strength of diaphragm increases, Strength of intercostal musclesincrease.
  8. 8. Inhaling and exhaling
  9. 9.  Air goes into the lungs, Lungs then expand (pressure is lowered), Intercostal muscles contract, Ribs then expand, Diaphragm goes downwards and contracts(to increase volume of the chest),
  10. 10.  Air is pushed out of the lungs, Lungs then inflate (pressure increases), Intercostal muscles relax, Ribs then go back down (relax), Diaphragm goes upwards and relaxes(decreasing the volume in the chest),
  11. 11.  Air is warmed, moistened and filtered as ittravels through the oral or nasal cavity, It then passes through the trachea, Into the right and left bronchus, Into the right and left lung, Passing through many of the bronchioles, To the millions o tiny air sacs called “alveoli”, Where gaseous exchange takes place... Here, oxygen passes out of the air and into theblood  carbon dioxide passes out of the bloodand into the air.
  12. 12. Tidal volume- the amount of air breathed in or out in one breath,Inspiratory capacity- the most you can breathe in after breathing out normally,Expiratory capacity- the most you can force out after breathing out normally,Residual volume- the amount of air left inside the lungs after breathing out as much aspossible,Vital capacity- the most air you can breathe in or out in one breath.Hypertrophy- get bigger and stronger,Atrophy- get smaller and weaker.SMOKING LEADS TO.... Systems.. Lung cancer, Trachea cancer, Nose cancer,Kidney cancer, Mouth cancer, Stomach cancer, Throat cancer, Heart disease, Oesophagus cancer.
