balance - ANSWER body position is kept in equilibrium. balance is greatest
when COM or gravity is inside the BOS limits of stability -
ANSWER Sway limits in which an individual can remain standing without
changing BOS
perturbations - ANSWER interferences with balance
anticipatory - ANSWER tension of postural muscles before performing
activity, eg reaching
reactive - ANSWER to react to external perturbations, example PT pushes the
pt.
muscle performance - ANSWER the ability of a muscle to do work. important
elements are: strength, power, and endurance.
muscle strength - ANSWER the maximum force measurable that is developed
by a muscle or muscles to move resistance in one maximal effort.
functional strength - ANSWER the ability of the neuromuscular system to
produce, reduce, or regulate forces, considered or applied, while performing
functional activities, smoothly and coordinately
muscle endurance - ANSWER the ability of the muscles to maintain physical
work throughout time without the accumulation of fatigue
, muscle power - ANSWER the speed with which a muscle can produce a force
and the force-velocity relationship are significant factors that determine muscle
power
muscle work - ANSWER force x distance (torque)
Agility - ANSWER nimbleness; capacity for moving quickly
Speed - ANSWER The distance an object travels for every unit of time
Coordination - ANSWER The capacity to utilize two or more parts of the body
together
Plyometrics - ANSWER type of dynamic-action resistance training based on
the premise that using the stretch reflex during jumping will activate more
motor units
resistance - ANSWER force from within or outside the body
resistance exercise - ANSWER type of active exercise in which a muscle
contraction is resisted by an external force.
anaerobic power - ANSWER brief burst, high intensity
aerobic power - ANSWER decreased intensity, repeated bursts
stages of plyometric exercise - ANSWER 1) eccentric
2) amortization
3) concentric response
4) eccentric preparation - shock attenuation
plyometric eccentric contraction - ANSWER creates elastic energy due to a
stretch stimulus
