Q
What is the process of injury and repair?
A
Inflammatory response
Macrophage infiltration
Fibroblastic and collagenous proliferation
Function of satellite cells
step 4 only occurs if myofibril was damaged
1
Q
Two competing events occur after injury, what are they?
A
Muscle regeneration
Production of scar/ fibrous tissue
2
Q
In failure of muscle and tendon what point is the most likely to fail?
A
myotendinous joint junctions
3
Q
Causative factors of muscle strains
6
A
Poor biomechanics Dys- Synergistic muscle contraction Insufficient warm up Inadequate flexibility Inadequate strength / endurance Inadequate rehab
4
Q
Physiological reasons for a lack of flexibility
A
B
A
A. Steeper stress curve -poor dissipation of energy -poor viscoelastic response -greater impact of force relaxation B.Change in length- tension relationship
5
Q
Clinical results of inadequate flexibility
A
B
A
A. Higher incidence of microtrauma -Muscle strains or tendinitis B. Decreased efficiency/ effectiveness -Movement dysfunction -Postural/ functional imbalances
6
Q
What does SAID stand for?
A
Specific Adaptations Imposed Demands Warming up throwing a ball, short to long
