Cardiovascular

Resting heart rate: Decreases due to the heart becoming more efficient at pumping blood with each beat.

A more efficient heart does not need to beat as often to supply the body with oxygen.

Stroke volume: Increases at rest and during exercise due to a thicker and more elastic heart muscle, increased blood volume and more efficient filling and emptying of the hearts chambers.

Cardiac output: Volume of blood pumped by the heart each minute. Increases significantly during exercise due to increase in HR and SV to meet metabolic demands.

CO = HR x SV

Hemoglobin levels: Increase to improve the blood's oxygen-carrying capacity, allowing muscles to perform at higher intensities for longer. This helps by delaying fatigue by delaying the build up of lactic acid.

Respiratory

Lung capacity: No significant increase to lung capacity as this is largely genetic.

Oxygen uptake (VO2max): Increases due to improved oxygen delivery and improved oxygen utilization.

Muscular

Capillary density: Slow twitch fibers (type I) increase in size, not numbers.

Mitochondria: Increase in size, number and density through mitochondrial biogensis. Improving the muscles ability to produce energy (ATP) aerobically.
