ch 2: number of different muscle tissues
3 skeletal cardiac and Smooth
ch 2Cell Memebrane of the muscle fiber
Sarcolemma
ch 2Type of muscle fiber that has fast contraction, and low aerobic capacity
Type IIb or Type IIx, Fast and glycolytic
ch2 Muscle fiber proportions good for endurance events
Type 1
ch2 Name the letters that correspond to the three different bands within a Sarcomere
A Band: The dark band seen as part of the striation effect
H Bands: Area between the A bands
I Band: Area between myosin molecules
ch 11 Responsiveness to stimulus to contract
irratation
ch 11 If a muscle fiber is stimulated by a single impulse at or above threshold value, it contracts.
all or none law
ch 11 Pushing against an immovable object, squeezing a hand grip dynamometer, is which type of muscle action
isomtereic
ch 11 Enlargement of muscle fibers is called
hypertrophy
ch 11 How long is a Macrocycle during a linear periodization model?
1 year
ch 13 Factors Affecting Sprint Performance
Duration of activity, Strength, flexibility, skill
ch 13 Which phase of running has less average power output than the other sprint phases?
High-Velocity Phase
ch 13 Sand running is a form of
Sprint-Resisted Training
ch 13 Weighted-Vest running is a form of
Sprint-Resisted Training
ch 13 In sprint cycling, what factors can be altered to improved cycling performance?
Conditioning of the rider
Changes in equipment
ch 14 Loss in muscle strength
Decreased/fading reflexes
Weakened coordination
Effects of Fatigue on Strength, Reflexes, and Coordination
ch 14 Task-Dependency Model
Fatigue is not a result of a single process, but of different mechanisms fatigue.
ch 14 The CNS regulates exercise performance to “ensure that catastrophic physiological failure does not occur during normal exercise in humans”.
Central Governor Model
ch 14 In the Accumulation Hypothesis, name one of the three metabolites in the muscle that have fatigue-causing effects
Lactate
Inorganic Phosphate
Ammonia
ch 14 During the Depletion Hypothesis, when high-intensity exercise cannot be maintained, this is due to a depletion in
ATP-PC System: Phosphagen Depletion
Anerobic/Krebs: Muscle Glycogen
