Recovery Flashcards
What does resistance type exercise induce?
sarcomere and z-disk damage
What is the role of PGC-1 alpha
Co-activator of transcription factors.
Read DNA and ultimately a functional protein is made
When is the master regulator of protein synthesis?
mTORC1
If inhibited, no gains in muscle are aquired post-exercise.
What are the ways to manipulate mTORC1?
Diet
Exercise
and or in combination to extreme environments.
The role of p70s6k
Activation induces protein synthesis.
How does cold water immersion affect p70s6k signalling?
Cold water blunts p70s6k response in an acute post-exercise study.
Chronic effects of cold water immersion
Active recovery had significantly higher gains in muscle mass compared to cold water immersion in 12 week study withthe implementation of strength training.
(310 grams).
Describe the efficacy of cold water immersion
CWI blunted or inhibited the acute molecular responses to strength training.
CWI blunted the chronic adaptive response to strength training.
What does massage therapy do post-exercise?
Attenuates inflammatory signalling after exercise-induced muscle damage.
Massage therapy did not alter muscle lactate concentration.
Describe what happens with the activation of FAK in relation to massage.
FAK phosphorylation increased mechanical activation of the skeletal muscle.
FocalAdesionKinase was activated as a result of the massage.
If FAK is activated, pgc1a pathway and mTOR pathway enhanced.
pgc1 in the nucleus, which can activate transcription factors.
Effects of TNFa
TNFa increases following exercise induced muscle damage.
Rheumatoid arthritis presents high levels of TNFa.
Inhibit protein synthesis by inhibiting mTORC1
Massage effects on TNFa
Reduction in TNFa post massage.
After a period of atrophy what can massage do?
Amplify myofibrillar protein synthesis rates after hind limb suspension followed by exercise and massage.
