Chapter 11 Chronic training
adaptations
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.
