Plastics-Plasticity Exam Questions with Correctly
Solved Answers
plasticity
potential that's out there, capacity to change
adaptation
how can you achieve plasticity? dosage
outcome
what're they doing now that they couldn't before ?
ambiguity
managing/making decisions with incomplete or unreliable info
risk
what you know about a situation based on probability - aren't sure if risk is worth potential
reward
complexity
lack of knowledge about specific topic
what three components contribute to uncertainty
ambiguity, risk, complexity
poor tolerance for ____ is associated with less empathy, greater burnout, and increased
psychological stress in healthcare
,ambiguity
uncertainty
dynamic, subjective perception of not knowing what to think, feel, or do
5 domains in cynefrin framework of uncertainty
1. complex
2. chaotic
3. complicated
4. simple/obvious/clear
5. disorder
senescent cells
stop growing but don't die - pointless
ableism
someone with disability
what combo in tissues gives most force
combo of passive stiffness and active muscle
Hills equation and what it means
change in m length / time = velocity (and force at given velocity)
if LT changes, then you're also changing ____ ____ and if ____ ___ changes, the your ____
____ of muscle changes too
, torque angle, torque angle, moment arm
what happens if you stretch or dose or stress a muscle too aggressively
cause inflammation responses, increased stiffness and fibrosis bc it turns on fibroblasts so muscle
starts to fill with collagen
sarcomerogenesis due to chronic lengthening? effects on LT? effects on FV?
creates sarcomeres in series - creates increased length - created increased velocity capacity
sarcomerogenesis due to chronic loading? effects on LT? effects on FV?
creates sarcomeres in parallel - creates increased hypertrophy - creates increased force capacity
why is isometric force the highest btw con, iso, ecc
bc velocity is 0 and when velocity is 0, that allows all xbridges. to be engaged at same time -
when load is increased, that decreases the chance that xbridges in parallel are all engaged
describe noncontact injury and how it relates to central drive
1. turn on 100% isometric bc bracing for impact
2. impact doesn't come when we expected
3. get mechanical breaking of xbridges with lengthening contractions happening
4. CNS starts to feel that we've started to break some xbridges so we decrease CNS drive so we
don't activated more and cause more damage
how can we use CNS and eccentric contractions to rehab someone (thinking about
noncontact injuries)
