Cardio respiratory

• Decreased rhr


  Same amount of blood in less breaths. Atheletes have a lower one
• faster recovery rate


  Heart recovery rate. Speed which the heart rate returns to normal.
• Increased stroke volume


  Regular exercise increases/volume at rest the hardest stronger
• Increased maximum cardiac out


  Governed by heart rate and stroke volume
• Increased size and strength of the heart

  Stroke volume increases, heart rate decreases regular aerobic exercise lowers issues of the heart
• IncreaseCapillarisation


  Used to oxygenate blood blood vessels are more elastic, flexible and efficient
• Increased red blood cell count

  Carries O2 helps athletes improve as muscles are oxygenated
• Decreased resting blood pressure

  Muscular wall is more elastic so there’s less force on the wall. High blood pressure is bad.
• Increased lung capacity and vital capacity

  Lung increases as O2 is delivered better to cope
• Increased alveoli


  More available gas exchange O2 as a result maximum aerobic capacity increases
• Increased strength of the diaphragm and intercostal muscles

  Increases airflow
