PAP, needs analysis, metabolic demand, cardio-respiratory Flashcards
What is Post activation potentiation?
A phenomenon by which muscular performance characteristics are acutely enhanced as a result of their contractile history
What is the underlying principle surrounding PAP?
- 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
What are the 3 principle mechanisms of PAP?
- Phosphorylation of myosin regulatory light chains (RLC)
- Increase in the recruitment of higher order motor units
- changes in the pennation angle
What are some considerations when talking about an athlete participating in PAP?
- muscular strength
- Fibre type distribution
- training level
- power : strength ratio
- type of subsequent activity
What are the 4 mesocycles?
- General physical preparation
- Specific physical preparation
- Pre-competition/competition
- Active rest
What are some characteristics of the general physical preparation mesocycle?
- develop general physical fitness qualities associated with sport
What are some characteristics of the specific physical preparation mesocycle?
- develop specific physical fitness qualities for sport
- retain general physical fitness qualities associated with sport
- introduce transfer of training
What are some characteristics of the pre-competition/competition mesocycle?
- maximize transfer of training
- minimize fatigue
What are some characteristics of the active rest mesocycle?
- recover from residual fatigue
What are the 5 biomechanical aspects of a needs analysis?
- neuromotor
- flexibility
- muscular endurance/hypertrophy
- maximum/neurological strength
- explosive strength/power
What are the 4 mechanical aspects of a needs analysis?
- muscular endurance
- anaerobic capacity
- aerobic power
- aerobic capacity
What are some sport (event) oriented aspects of a needs analysis?
- sport analysis
- skill analysis
- injuries analysis
- kinematic analysis
- kinetic analysis
- aerobic analysis
- anaerobic analysis
- time-motion analysis
What are some athlete oriented aspects of a needs analysis?
- strengths
- weaknesses
- needs
- goals
What are some common issues with needs analysis?
- potential lack of research on your sport/event
- accessibility to available information
- too much information (complicates research)
What are myotatic stretch reflex?
sudden violent stretch of muscle
What is a steady state?
- continuous/sustained aerobic activity
- intensity stays within the same range for duration of the workout
What is non-steady state?
- non-continuous/interval activity
- combination of higher and lower intensity demands
What are some limits to performance in steady state activities?
- oxygen delivery to working muscles
- oxygen extraction by working muscles
- oxygen utilization by working muscles
- substrate availability
what is the easiest way to determine your target pace?
race distance/target race time
What are some limitations to non-repetitive performance?
- technique
- intensity at anaerobic threshold
- VO2max
What are some limitations to repetitive performance?
- work bouts (technique, intensity at anaerobic threshold,
VO2max)
What is a time motion analysis?
- analysis of the type and intensities of movement in non-steady state activity
- analysis of duration of movement of different intensities
What is cross bridge cycling?
describes the calcium-dependent interaction of actin and myosin during muscle contraction
What is catabolism?
- enzyme attaches to molecule
- molecule splits into 3 constituent molecules
What is synthesis?
- enzyme attaches to 2 molecules
- molecules are combined to create a new molecule
What is the limitations of creatine phosphate system?
- the amount of creatine phosphate
What are the limitations of the glycolysis system?
- amount of phosphofructokinase
- amount of lactate dehydrogenase
- acid production
What are the limitations of the oxidative phosphorylation system?
- number of mitochondria
- amount of SDH and CS
- oxygen availability
What is the cori cycle?
- turning lactate into glucose because the body can’t use lactate for energy
