STUDY GUIDE
ATP-PC system
simpliest and fastest, occurs without oxygen (anaerobic), provides energy for high
intensity, short-duration
ex: power and strentgh
Glycosis System
produces lots of energy for 30-50 sec. Typical bc it falls in the time frame of 8-12
reps
Oxidative System
most complex
B- oxidation
breakdowns triclgycerides into free fatyy acids to produce more ATP
Myth of Fat Burning Zone
,higher intensity workouts require greater contribution from fat despite the increase
in need of fuel source from carbs
Biomechanics
internal and external forces acting on the human body and the effect produced
Superior
above a reference point
inferior
below a reference point
Proximal
reference closest to the center of the body or reference
Distal
refernence furthest away
, Anterior
Reference in front of the body
Proprioception
The body's ability to to sense the relative position of adjacent parts of the body
Ex: when walking our feet give us proprioception about the type of surface we are
on.
Mechanoreceptors
specialized structures that recognize pressure in tissue and transmit signals to
sensory nerves.
Muscle Spindles
sensory receptors in the muscles that are parallel to the muscle fibers and are
sensitive to change in muscle length. Spindles stretch with muscle and sends
information to CNS.
helps to prevent muscles from stretching too far or too fast
