2. Strength ( isometric, isotonic, multiplayer, open/closed)
3. Function
4. balance/ proprioception

Question 2

Components of joint motion

Answer 2

PROM
AROM
Stretching
Mobs

Question 3

Components of strength

Answer 3

isometric
isotonic
multiplaner
open/closed chain

Question 4

Examples of multiplanar exercises (strength)

Answer 4

PNF
manual resistance
theraband
kettle bell weights

Question 5

Benefits of closed chain

Answer 5

greater joint surface congruity
proprioceptive input
muscular co-contraction

Question 6

contraindications for closed kinetic chain

Answer 6

• sever joint instability
• restricted weight bearing
• severely restricted joint sense
• pain, swelling, undue apprehension, abnormal mvmt

Question 7

quick rapid movement that involves pre stretching the contracting muscles to activate the stretch shortening cycle

Answer 7

plyometrics

Question 8

Describe the stretch shorten cycle:

Answer 8

eccentric lengthening
amortization phase
concentric shortening

Question 9

objectives of plyometrics

Answer 9

• improve excitability of nervous system
• improve power
• neuromuscular reactivity

Question 10

guidelines for plyometrics

Answer 10

• 80-85% normal strength
• 90-90% normal ROM
• specific to performance

Question 11

improved speed of stretch reflex
desensitized GTO
improved neuromuscular coordination
rate of stretch is most important

Answer 11

training effects of plyo
