Recovery Flashcards
1
Q
What is the energy charge of the cell?
A
ATP:AMP ratio
2
Q
How does muscle respond to exercise genetically?
A
- Repeated exercise increases transcription and expression
- Increased protein content and enzyme function
- Improvements in exercise performance
3
Q
Describe transcription and translation.
A
Transcription
- PGC1a activates transcription factor
- Transcription factor bonds to gene to create mRNA
Translation
- mRNA then thread through ribosome to generate functional protein
4
Q
Describe mTOR adaptation to resistance training.
A
- Exercise stimulates integrin mechanoreceptors
- These signal mTOR complex
- This phosphorylates and deactivates a binding protein 4EBP1
- Which holds eukaryotic initiation factor4E, which allows mRNA to be threaded through ribosome after the activation via p70S6K
5
Q
Describe how mTOR activates a ribosome.
A
- Activates p70S6K
6
Q
What happens in active recovery compared to ice baths on a cellular level?
A
- P70S6K phosphorylation increased in both groups
- Remained elevated in active recovery only
- Cold water immersion impairs activation of signalling
7
Q
What characteristics are improved with active recovery when compared with cold water immersion?
A
- CSA
- Mass
- Fibre type
- Strength
- RFD
8
Q
Describe non-mTOR adaptation to endurance training.
A
- Reduced energy charge activates AMPK sensor
- Mechanical stimulation of FAK
- Activation of PGC1a (transcription factor)
- Activates mitochondrial biogenesis
9
Q
What does massage do to the cell and through which pathway?
A
- No change in lactate or mTOR
- FAK phosphorylation
- Increase in PGC1a
- Mitochondrial biogenesis pathway
10
Q
What does massage do for inflammatory response?
A
- Less TNFa
- Less NFkB
- Less muscle protein breakdown
