• improved efficiency/strength of the respiratory muscle (diaphragm and intercostals muscle) • increase the proportion of the alveoli (air sacs that diffuse oxygen into the capillaries) • increase the number of capillaries, which diffuse oxygen from alveoli into the blood. • increased tidal volume and vial capacity This means that more oxygen can be consumed and transported from the alveoli into the capillaries and into the red blood cell. The remaining system then transports oxygen working muscles and eventually back out as Co2.

Adaptation to the lungs

• hold more blood, increasing heart stroke volume (amount of blood pumped out of the heart per beat) • beat with more force, which again will increase stroke volume The result of this will be: • a reduction in resting heart rate (number of beats per minute) • an increase in maximum cardiac output ( amount of blood pumped out of the heart in 1 minute). Overall there will be more blood going to the working muscles, allowing the athlete to exercise for longer in the aerobic zone (taking longer to reach anaerobic threshold) as the exercise intensity increase.

Adaptation to the heart

Vasomotor Control: the arteries will become more elastic, allowing them to vasodilate (become wider) and vasoconstrictor (become narrower) more efficiently. This improves the transportation of the blood-working muscles. This also a real healthy benefit by reducing the potential impact of hypertension (high blood pressure)

Adaptation to the cardiovascular system

Increase the number of red blood cells and therefore more hemoglobin. This will mean that the blood will be able or carry more oxygen to the working muscle. This improves the transportation of blood to the working muscles. This is also a real health benefit by reducing the potential of hypertension (high blood pressure).

Changes in blood

• Large numbers of capillaries present to diffuse the oxygen into the muscles. • A large number of mitochondria (the power plant of the cell, which converts oxygen and food into energy). • Increase the amount of myoglobin (a concentrated form of hemoglobin that transports oxygen into the mitochondria). This will mean that greater amounts of oxygen into the capillaries and are then used for energy within the muscle (mitochondria).

Adaptation to the muscle

Exercise stimulates the deposition of calcium which makes the bones stronger. Tendons and ligaments increase in strength and flexibility

Adaptation to the bones and joints
