exercise- part 2

Question 1

why does muscle length matter

Answer 1

reduce injury, improve warm up, reduce length- increased risk of injury, reduces pain

Question 2

what does all muscles rehabilitation need

Answer 2

need to be worked in range relevant to muscles normal function. any benefits will be specific to type of exercise done- contraction code- concentric, eccentric, position load

Question 3

biomechanics properties of soft tissue

Answer 3

stress- the physical force applied to a material, strain- a measure of deformation the material. micro-failaute occurs at 3-10%. physio- work within elastic reigion,

Question 4

biomechanics properties of soft tissue- creep, hysteresis, sarcomerognsis

Answer 4

creep= elongation of tissue that occurs over a constant load. hysteresis- the energy lost and not returned to a system. inducing hysteresis in the tissue helps to reduce tissue stiffness, creates heat and restores the tissue normal mechanical response to loading.
sarcomerogensis- adding sarcomerere- production of sarcomere

Question 5

eccentric and concentric exercises

Answer 5

stressing muscles at the end of range, stimulation muscle more than stretching (greater force), triggers bigger reaction in muscles

Question 6

problems with stretching

Answer 6

improve ROM, lead to impair immediate performance- less forces, no alterations in length, chronically linked with strength changes, changes in pain perception

Question 7

myths of stretching

Answer 7

we produce plastic deformation, they reduce risk of injury, they reduce DOMs, you must do them before and after exercise

Question 8

how does stretching work

Answer 8

changes in muscle length- creep. changes in viscoelastic properties of MTU. transient and short lived. eventually may add sarcomeres (eccentric or ER strength training works). pain perception. pain gate- neurophysiological pain relief- give proprioceptive feedback- large psychological impact on brain

Question 9

types of stretching- self administrated

Answer 9

static, dynamic, contract- relax, hold- relax

Question 10

types of stretching- therapist administrated

Answer 10

SSTM physiological, SSTM accessory, contract- relax, hold- relax

Question 11

balance

Answer 11

an even distribution of weight enabling someone or something to remain upright and steady
balance tests- Y balance test, star excursion test

Question 12

proprioception

Answer 12

perception of the position and movement of the body

Question 13

stability

Answer 13

COG, BOS, an object is most stable when its COG is low and the line of gravity falls at the centre of its BOS

Question 14

5 basic starting position

Answer 14

kneeling, sitting, lying or supine hanging, standing
