Potential Test Q's Flashcards
What contributes to athlete force production?
Multiple Joint
Explosive
Train on your feet
Free weights
Tissue healing phases
Inflammation, Fibroplastic Repair Phase, Maturation-Remodel Phase
Basic pattern of healing
Inflammation
Repair
Remodeling
WOTF describes muscle and connective tissue elasticity?
Ability to return to original resting length
Acceleration component should be optimized when working w/ older clients
True
Accentuation occurs when athlete trains only in range of sport movement where the demand for high force production is
Maximal
In the intentionally slow lift method, the coactivation of this type of muscle is used
Antagonist
Accommodation occurs when
No change in training load over time period
When tendons in bone are inserted farther from center, the speed of movement
Decreases
Force production increases
As there is an increase in lactate threshold, high intensity shifts
To the right
During high intensity there is peripheral fatigue due to metabolic acidosis
True
When tendons in bone are inserted farther from center, the speed of movement
Decreases
Force production increases
As there is an increase in lactate threshold, high intensity shifts
To the right
During high intensity there is peripheral fatigue due to metabolic acidosis
True
The heaviest weight that is lifted through a ROM cannot be greater than the stretch at its weakest point
True
Selection of proper ____________ affects the maximal values of the external force that an athlete can produce
Body position
Maximum strength is equivalent to rate of force production
False
Altitude can impair performance on endurance endurance tests, although not on tests of strength & power
True
Altitude can impair performance on endurance endurance tests, although not on tests of strength & power
True
Women train to get larger, more buff
False
Children grow at a constant rate
False
Linear Periodization Model
Traditional resistance training periodization model with gradually progressive mesocycle increases in intensity over time
Undulating / Nonlinear
A periodization model alternative that involves large fluctuations in the load & volume assignments for core exercises
Aerobic endurance testing in the heat
Symptoms of hyponatremia or water intoxication:
Extremely dilute urine Bloated skin Altered consciousness Loss of consciousness No increase in body temperature
Aerobic endurance testing in heat
Symptoms of heatstroke or heat exhaustion
Cramps, nausea, dizziness, difficulty in walking or standing, faintness, garbled speech, lack of sweat, red or ashen skin, goosebumps
Pennate muscle
Muscle with fibers that align obliquely with the tendon, creating a featherlike arrangement
Strength definition
Capacity to exert force at any given speed
Acceleration
Change in velocity per unit time
Proprioceptors
Specialized sensory receptors that provide the CNS with info needed to maintain muscle tone and perform complex coordinated movements
Mechanical advantage
The ratio of the moment arm through which an applied force acts to that through which a resistive force acts
Sliding filament theory
Actin filaments at each end of sarcomere slide inward toward the myosin filaments pulling Z-lines toward center of sarcomere thus shortening the muscle fiber
Sliding Filament Theory (phases)
Resting Excitation contraction coupling phase Contraction Recharge Relaxation
Second class lever
Muscle and resistive force act on same side of fulcrum with the muscle force acting through moment arm LONGER than that through which the resistive force acts
Mechanical advantage > 1.0 this required muscle force is smaller than resistive force
Third class lever
Muscle and resistive force act on same side of fulcrum with the muscle force acting through a moment arm shorter than that through which the resistive force acts
Mechanical advantage < 1.0
Fluid resistance
Resistive force encountered by an object moving through a liquid (liquid or gas) or by a fluid moving past or around an o hectares or through an opening
