1

myostatic contacture

Muscle-tendon unit is adaptivly shortened (decrease sacromere units)

2

Psudomyostatic contracture

impaired mobility w limited ROM due to hypertonic pacicity or rigitity (results in spasms, gaurding, pain)

3

Arthrogenic contracture

results of intra articular pathologies (adhesions, osteophytes, ireggularities)

4

Periarticular contracture

connective tissue crossing a joint capsule loses mobility

5

Fibrotic contracture

fibrous changes in connective tissue

6

irreversible contracture

Normal muscle tissue + connective tissue are replaced w non extendabole fibrotic adhesions, scar tissue and bone

7

Some contraindications of stretching

-Bony block
-recent fx
-acute inflamation
-sharp pain
-existing hypermobility

8

What is PNF stretching

uses active muscle contraction as a strech to facilitate or inhibit muscles

9

Conclusion of dynamic vs static stretching in jump hieght

No sig diference

10

2 joint receptors and what they do

Ruffini endings- on flexion side of joint, respond to load changes vs displacement (stimed by extreme motion)

Pancian corpuscles- located in joint capsul and measure joint motion

11

2 muslce + tendon receptors an what they do

GTO- respond to tension

Muscle spindles- respond to stretch + effects of contraction

12

3 systems that influence balance

1. Visual
2. Somatosensory
3. Vestibular

13

Tests to meausre sensory function

1. Sit to stand test
2. Rhombergs
3. Single leg stance
4. Tandem gait

14

neuropathic vs nocioceptive pain

neuropathic- nerve damage

Nocioceptive- soft tissue damage, caused by stim of peripheral nerve fibres

15

when a painful stim is encountered the body relays info from the somatic sensory receptors to the cerebra cortex via

1. First order neuron (dorsal root ganglion)
2. Second order (spinothalmatic tract)
3. Third order (thalmus)

16

What is the gate control theory and what fibres decrease ascending transmission

pain and non painful stim go thru same pathway, Large Ab fibres decrease ascending trasmission

17

V02 max in trained and untrained indv

untrained- m(35-40 ml/kg/min) f(27-31)

Trained- m(85) f(77)

18

What is V02 max dependednt on (4)

-heart to pump blood
-Tissues to extract o2
-body to ventilate
-The alveoli to extract o2 from the air

19

what are the 3 energy systems in quickest to longest

PC (10-30sec)
anaerobic glycolytic (up to 3 mins)
Aerobic

20

activity guidlines for adults

150 mod to vigerous aerobic physical activity per week in bouts of 10 mins or more

21

at what V02 and MaxHr does conditioning response generally occur

50-85% V02max

60-90% max HR

22

how to do karvonen formula for getting estimated exercise HR

1. Calculate HRR- HRmax-HRrest

2. HRR* % u want+ HRrest

23

benifits of warm up for cardiovascular

-increase mm temp
- dialation of capillaries with increased circulation to promote o2 delivery
-increase venous return

24

general guidlines for cardiovascular rehab program

warm up- 5-10min
Activity- 20-30 mins with target HR
cool down-20-30 mins
