exercise Flashcards
which çreates more force eccentric or concentric?
eccentric (lengthening)
Why is the latent period important?
simple twitches, summation and simple twitches happen before tetany
what is the most efficient motor units?
slow, type I because the Type II are easily fatiguable
endurance training increases
capillary density and mitochondria
couch potato to exercising
Past IIB–>IIa–> I (slow)
Muscle atrophy conversion
Slow I—>IIa—>IIb
strength within first 8 weeks:
neural factors not hypertrophy factors
heel strike
glut max
foot flat
quad
toe off
iliopsoas
terminal swing
quads
foot slap
common fibular nerve injury
limb muscles active during gait
gastroc/rectus, abductors and
glutmed/min
bicpes femoris to stop
high stepping gait
common fibular nerve damage
determinants of gait
pelvic tilt (glut med/min (adductor group))
pelvic rotation and movement of the femoral head
biggest risk factor for having a fall
having had a fall
white men 85+
worst px after fall
causes of falling
vision
proprioreceptive system
vestibular system
acute illness
medication (benedryl, anti-cholinergic, narcotics)
goal BP for over 80yo
150/90
65 BP goal
140/90
Change in baroreceptive senitive as we get older can cause
hypotension upon rising and resulting fall
components of gait
antigravity
balamce
stepping
higher CNS
stride lengths huld be
at least 2 foot lenght
ataxic
A/P sway, tremor, wide based stance
test: heel to toe
antalgic gait
with a joint that’s spurring.
a limp
R leg affected? cane in left hand
Apraxic gait
can’t walk. neuro issues
Festinating gait
Parkinson’s
