Anaerobic exercise

- increase aerobic capacity

- increase buffering capacity

- Glycolytic system

- ATP-PCr system

- small increases in stroke volume

- decreased resting blood pressure is greater

- decreased submaximal heart rate

- decreased resting heart rate

- small increase in left ventricle size

- small increase in VO2 Max

- small increase in cardiorespiratory endurance

Aerobic exercise

3. Metabolic adaptations

- glycogen sparing effect: less rely on carbo/glycogen

- muscle store more triglyceride

- muscle store more glycogen

- increase aerobic enzyme activity

- decreased VO2 during submaximal exercise

- increased capillary density

- increased mitochondrial density

2. CV adaptations

- decreased heart recovery

- lower heart rate during max workloads

- lower heart rate during sub max workloads

- lower resting heart rate

- increased stroke volume

- increased capillarisation of the heart muscle

- heart size - cardiac hypertrophy

1. Respiratory adaptations

- Increased respiratory rate and pulmonary ventilation at maximal exercise levels

- increased Tidal Volume at maximal exercise levels

- slight increase in Total lung Capacity

- respiratory system functioning usually does not limit performance

- arterial-venous O2 difference

- pulmanory diffusion

- pulmanory ventilation
