Physiology Year 3 Week 8
Metabolic Adaptation to Endurance and High Intensity Interval Training
Aims:
1) Explain the main adaptations that occur in response
to ET and HIT
2) Understand the changes in metabolic regulation that
underpin the adaptations to:
● CHO metabolism
● Fat metabolism
Key concept
Endurance training leads to adaptations which reduce the degree of perturbations to
homeostasis for a given intensity, delaying the onset of fatigue…
,Effects of endurance training:
● Increased enzyme content and/or activity
● Improved metabolic function
● Increased mitochondria size, localisation, to IMTG, number
● Improved match between ATP demands and oxidative metabolism
● Increased capillary density and substrate transport proteins
● Improved fuel delivery to working muscle
, Increased fat metabolism due to ability to use IMTG’s as a result of regular endurance training
Increase in VO2 max, so need to find out a new workload (%of VO2 max) so they can train at
the same relative intensity to make the test fair and valid/reliable
