Acute adaptations from strength exercises

Question 1

What is Post activation Potentiation (PAP)?

Answer 1

A resistance exercise preformed after a explosive movement improvs performance above the athletes perceived best

Question 2

What is Fatigue?

Answer 2

–Depletion of fuel 
–Build up of metabolic by-products 
–Thermoregulation 
–Neural dampening
–Reduction in muscle contractile elements

Question 3

Three mechanisms associated with Post activation Potentiation (PAP)?

Answer 3

An increased sensitisation to the phosphorylation process on the myosin light chains

Increased alpha motor neuron recruitment and a reduced reciprocal co-contraction

A decreased angle of pennation

Question 4

What is the neural recruitment and inhibition of the co-contartcionRenshaw cell?

Answer 4

• First contraction –activates large motor units
• Reduced inhibition by the Renshaw cell
• Second contraction recruits more larger motor units – different muscle action

Question 5

Methods of eliciting Post activation Potentiation (PAP)?

Answer 5

•Vibration activation methods

•Isometric activation methods
–Electrically induced
–Voluntary induced

•Dynamic activation methods
–Isoinertial strength exercises
–Plyometric

Question 7

During thermic effect what does each degrees eqante too?

Answer 7

1* = 1% improvment of performance
