25
Why is it important to stretch through the range of movement, not just at ROM?
Enhances muscle length and increases flexibility
26
What is the effect on regular stretching on neural pathways?
Interrupts the pathways that force co-contractions and prevent stretch going further, switching them off increases the depth of the strength
27
How can tendons be affected by strength and flexibility training?
Reduces strain injuries by strengthening a non-contractile tissue, higher strength and endurance
28
When does the hamstring quadriceps ratio begin to cause injury?
Hamstring below 60% of quad strength
29
What is a isokinetic training system?
Controls angels and speed, isolating the muscle groups to target rehab, concentric to concentric contraction
30
Why is early mobilization important?
Rescues degree of postinjury disability to reduce scar tissue build up
31
Why does exposure to tensile forces improve strength of tissues?
Improves quality and strength of the connective tissues at the site of injury and the organisation of regenerating muscle fibers - only occurs with no pain
32
Why are isometric contractions good for rehab?
There is reduced pain as there is no movement prevents atrophy of muscles, same progression to build back the strength of the muscle
32
What is the progression of contractions?
Isometric - isotonic (concentric) - concentric-eccentric coupled activities - sport specific - replication of force in game
33
What does rehab allow?
Increased contractile strength, increased tensile strength, increased neuromuscular control, decreased scar tissue build up
34
What are the 3 muscles in the hamstring group?
Semimembranosus, semitendinosus and bicep femoris
35
What is the hamstring required for?
Explosive and repetitive movements
36
How is hamstring injury tested for?
Single leg raise
37
Whats the rehab for hamstring strain?
Passive stretching, SLR (anterior pelvic tilt efficacy improved), PNF, weight bearing avoided
38
What does PNF stand for?
Proprioceptive neuromuscular facilitation
39
What is reciprocol inhibition?
Neurological co-activation of contractions at a joint
40
What causes an ankle sprain limp?
Lack of dorsi flexion, peroneal prevents inversion
41
How can dorsiflexion be regained in ankle sprain?
Periods of weight bearing, passive mobalisation and RICE
42
Whats the benefit of peroneal strengthening?
Improves the strength and control of the muscles, eccentric with proprioception
43
Why is biomechanics used in protective equipment development?
Combines engineering and anthropometrics to specifically design equipment for an individual athlete
44
Why is compliance with standards important (boxing) ?
Makes sure that the individual is actually protected and fits the size and weight parameters of the sport
45
What is the British standard?
British kite mark (BS)
46
47
What are some well know standard agencies?
ANSI, ASTM and DIN (American national standards institution, American society for testing and materials, Germany
48
What are some areas of interest with protective equipment?
Helmets, shin guards, eye guards, boxes, abdominal guards/protectors and chest guards
49
What are the 3 main causes of injury?
Training, anatomical alignment and equiptment
50
What is the cause of injury dependent on?
Magnitude, rate of application and frequency
51
How does biological loading affect injury risk?
Over/under loading can cause varus or valgus guiding forces incorrectly through the joint increasing injury risk
52
Whats the role of cushioning in shoes?
Shock absorption, slower rate of application, reduces the effect of the force
53
How does cushioning vary in shoes?
The level of cushioning can vary as well as the positioning - heel, sole, medial or arch support
54
How can shoe performance be impacted?
Wet shoes force absorption decreases, after 400km loss of 30-50% of support
55
What are some features shoe manufactures use as cushioning?
EVA, patented options (air bubbles), rear foot control, sole density and orthotics
56
How does midsole absorption affect force outcome?
quicker rate of ankle pronation, bigger leaver, measured in durometers
57
How is peak impact force affected by the 3 foot strikes?
Isn't affected, acceleration is
58
What are the 3 types of footstrike?
Forefoot, rearfoot and midfoot
59
When did wearing shinpads in football become compulsory?
1990
60
What percentage of players wear shinpads in training?
30%
61
What percentage of football injuries occur because of inferior footwear?
13.5%
62
What equation links acceleration and mass?
F=ma
63
Whats the replationship between accelration and mass in the neck?
Proportional when lax, when tensed larger mass has a larger force
64
What is the brain surrounded by?
Cerebral spinal fluid (CSF)
65
Whats the role of CSF in collisions?
To distribute the force
66
How does rotation effect impact?
CSF is uneven and the brain delayed, creates a shearing force that causes damage
67
Whats a soft shell helmet?
Breaks up, deforms easily, no sharp blow, 0.2-0.3kg
68
Whats a hard shell helmet?
Fibreglass, ABS, spreads the load, EPS crushed, 0.5kg
69
What torque does concussion occur at?
7500 rad/s^2
70
What is torque of the head?
Head bends and rotates forwards
71
Whats the acceleration in a hard/soft shell?
200ms in soft and 36ms in hard
72
What ANSI criteria do helments have to meet?
Acceleration below 300g
73
Waht mass does acceleration cause brain damage?
400g
74
Whats the force through the neck in hybrid compression tests?
5500N
75
What is the function of body armour?
Protect major body organs
76
What is inner core comprised of?
Internal obliques, transverse abdominus, pelvic floor, multifidus and diaphragm
77
What is the outer core comprised of?
External obliques, erector spinae, latissimus dorsi, gluteal, adductors, hamstings
78
What is the importance of the core in movement?
Transfers force from lower to upper, providing stability of the 2 extremities
79
What movement does the external obliques cause?
With flexion of spinal column allows for individual twisting
80
What movement does the erector spinae cause?
Alllows for difference in lumbar and thoracic movement
81
What movement does the latissimus dorsi cause?
Rotatory movement of spine when arms are fixed
82
What movement does the gluteals cause?
When feet touch the floor, pelvis moves forward
83
What movement does the adductors cause?
When feet are touch ground pelvis drops
84
What movement does the hamstrings cause?
Extension of pelvic girdle when legs touching the ground
85
Whats the effect of pelvic movement on energy efficiency?
Pelvis rotation changes the center of mass and energy is required to stabilize
86
What is the effect of a weak lordosis?
Excessive arching of the lower back causing pain, uneven load on spine and excess pressure on nerve
87
What exercise can be completed to train the transverse abdominas?
Pulling bellybutton towards the spinal column, controlling diaphragm strengthens TVA, on all 4s 10 sets of 10 seconds
88
What are some of the effects of core weakness?
Aligment changes and therefore loading on knees, back problems from pelvic tilt, lost energy, lower center of gravity, hip angel changes
89
How can change in centre of gravity effect stride length?
Shorter and less efficient, reducing performance outcomes
90
What exercises can be used to strengthen core?
Waiters bow (20 degree hips), lunge lumbar spine in neutral and hips level, press up, supermans and core stability slide
