Q

What is the underlying principle surrounding PAP?

A
  • heavy loading prior to explosive activity induces a high degree of CNS stimulation which results in greater motor unity recruitment lasting anywhere form 5-30 minutes

Q

What is a steady state?

A
  • continuous/sustained aerobic activity
  • intensity stays within the same range for duration of the workout
17
Q

What is non-steady state?

A
  • non-continuous/interval activity
  • combination of higher and lower intensity demands
18
Q

What are some limits to performance in steady state activities?

A
  • oxygen delivery to working muscles
  • oxygen extraction by working muscles
  • oxygen utilization by working muscles
  • substrate availability
19
Q

what is the easiest way to determine your target pace?

A

race distance/target race time

20
Q

What are some limitations to non-repetitive performance?

A
  • technique
  • intensity at anaerobic threshold
  • VO2max
21
Q

What are some limitations to repetitive performance?

A
  • work bouts (technique, intensity at anaerobic threshold,
    VO2max)
22
Q

What is a time motion analysis?

A
  • analysis of the type and intensities of movement in non-steady state activity
  • analysis of duration of movement of different intensities
23
Q

What is cross bridge cycling?

A

describes the calcium-dependent interaction of actin and myosin during muscle contraction

24
Q

What is catabolism?

A
  • enzyme attaches to molecule
  • molecule splits into 3 constituent molecules
25
Q

What is synthesis?

A
  • enzyme attaches to 2 molecules
  • molecules are combined to create a new molecule
26
Q

What is the limitations of creatine phosphate system?

A
  • the amount of creatine phosphate
27
Q

What are the limitations of the glycolysis system?

A
  • amount of phosphofructokinase
  • amount of lactate dehydrogenase
  • acid production
28
Q

What are the limitations of the oxidative phosphorylation system?

A
  • number of mitochondria
  • amount of SDH and CS
  • oxygen availability
29
Q

What is the cori cycle?

A
  • turning lactate into glucose because the body can’t use lactate for energy
