Year 3 Week 2 Physiology
Measuring adaptations to exercise
● Aerobic capacity
● Strength and power
● Injury and detraining
The ‘Black Box’ of exercise biology
Molecular methods are the tools required to investigate the mechanisms by which diet,
exercise and disease lead to changes in ‘phenotype’
How do athletes adapt to training?
Principle of homeostasis
Cell signalling during exercise
, Exercise induces…
● Mechanical/energy stress which is…
● Sensed by proteins which…
● ‘Unlocks’ DNA and genes are copied to mRNA (transcription) then…
● mRNA carries message to create chains of amino acids which…
● Chains are folded to make mature protein then…
● Proteins carry out functions to deal with future…
● Back to start of loop - Exercise inducing mechanical/energy stress
