PAP Viva Revision Flashcards
1
Q
Define PAP
A
- Implementing a resistance exercise
- Before an explosive movement
- To improve performance above perceived best
2
Q
What are the 3 main mechanisms of PAP?
A
- increased sensitisation to phosphorylation on myosin light chains (Szczesna)
- increased a motor neurone control via renshaw cell and reduced co-contraction (Jeffreys)
- decreased angle of pennation (Mahlfeld et al)
3
Q
What fibre type is linked to PAP responders? And why?
A
Type II (Hamada)
4
Q
What are the key methodological factors for PAP?
A
- Participant characteristics
- Specificity of activation
- Intensity
- Volume
- Recovery
- Study Design
- Warm up
(Sale, Tsoukos)
5
Q
What participant characteristics are linked to responders?
A
- Strength
- Fibre type
- Training level
- Training history
(Tillin&Bishop)
6
Q
Name other possible PAP mechanisms
A
- Improved synchronisation of nerve firing
- Approximation of actin & myosin
7
Q
What is the enzyme which alters the shape of the myosin head and what activates it?
A
- Myosin light chain kinase
- Ca2+
8
Q
Who said neural and strength interlink?
A
Pion
9
Q
Who linked RFD characteristics to potentiation?
A
Maffiuletti
10
Q
Who did the research on M waves and H reflex?
A
Masuilis
11
Q
How does mechanism 1 Work?
A
- release of Ca2+
- alters structure of myosin head
- moving from filament backbone
- increases actin-myosin sensitivity
