Chronic adaptations Chronic adaptations to training occur as a physiological response to the increased demands placed on the body They occur in the cardiovascular, respiratory and muscular systems and lead to improved performance in an athlete
Chronic adaptations as a result of aerobic training Aerobic training adaptations improve the efficiency of the aerobic energy system to provide energy to the working muscles by increasing the body’s ability to take up, transport and use more oxygen.
Cardiovascular adaptations: heart The heart is like any muscle, it will respond to training by getting bigger and stronger. Add another column to explain how each of the heart adaptations increase performance
Cardiovascular adaptations: blood vessels Increased capillarisation in muscles and heart, how does this increase performance? Decreased blood flow to working muscles at rest and sub maximal intensity, why does this occur?
Cardiovascular adaptations: blood Increase in blood volume Increase in total amount of haemoglobin, what is a haemoglobin? How does it improve performance?
Respiratory adaptations Copy down the table then research and write down how each adaptation contributes to improved aerobic performance
Muscular adaptations Copy down the table then research and write down how each muscular adaptation improves aerobic performance.
Chronic adaptations: anaerobic training Anaerobic training effects are seen in the cardiovascular but mainly in the muscular system. Find and list the anaerobic cardiovascular adaptations, page 310
Anaerobic adaptations: muscular Muscular anaerobic training adaptations occur in the muscle fibres, but mostly in the fast twitch fibres only.
