Exert tension while muscle LENGTHENS

Question 8

Open Kinetic Chain

Answer 8

Furthest away from body free and not fixed to ground

Question 9

Closed Kinetic Chain

Answer 9

Furthest away segment fixed

Question 10

Isokinetic

Answer 10

Maximum contraction at constant velocity throughout entire ROM

Question 11

Isotonic Strength Tests

Answer 11

Pull ups
10RM
1RM

Question 12

1 Rep Max Test

Answer 12

5-10min general and specific warm up
Rest and stretch 1min
Do 3-5 reps @69-80% of 1RM
Rest 1min
Inc weight slightly do 1 Rep
Rest 3min
Inc weight slightly do 1 rep
Repeat till Px fails to lift weight

Question 13

1RM equation

Answer 13

1RM ÷ BW(kg) =relative strength value

Question 14

Isokinetic Strength Tests

Answer 14

Cybex
KinCom
Biodex

Question 15

Isometric Muscle Strength tests

Answer 15

MMT
Handgrip test
Leg/back strength
Planking
Wall sit
Flexed arm hang

Question 16

MMT

Answer 16

×use Lafayette MmT/bp cuff
0=no contraction
1=trace contraction, no joint movement
2=contraction, joint movement with gravity
3=joint movement against gravity
4+-=contraction against gravity+moderate ext resistance
5=contraction against gravity+strong external resistance

Question 17

Handgrip Test

Answer 17

-use Jamar/Takei handgrip dynamometer
1. Stand upright
2. squeeze handgrip quickly and tightly as possible then release pressure
3. 3 trials, 1 min rest select best and add R+L=score
÷Bw=relative strength value

Question 18

Leg strength

Answer 18

1. Knee flexed at 30-40*
2. Pronated grip with bar across thighs
3. Extend knees then pull bar straight up

Question 19

Back Strength

Answer 19

1. Fully extended knees with head and back erect
2. Over under hrip with bar across thighs
3. Roll shoulders back
4. Oukl up into extension

Question 20

Sahrman Core stability test

Answer 20

T level core stability test
Evaates abdominal muscle function

Question 21

Muscle Balance ratio

Answer 21

-strength imbalance=compromise joint stability and inc risk of musculoskeletal injury
-agonist:antagonist
-affected by force-velocity of Muscle groups
-compare 1Rm for muscle groups

Question 22

Muscle balance ration

Answer 22

Hip/elbow/trunk ext:flex 1:1
Ankle invertors:evertors 1:1
Shoulder Ext/IntR:Flex/ExtR 3:2
Knee ext:flex 3:2
Ankle plantar:dorsiflex. 3:1

Question 23

Functional fitness testing

Answer 23

Children:1RM
Elderly:arm curl test, 30sec chair stand test
