Quiz 3

Question 1

what has been shown to improve change of direction ability

Answer 1

lower centre of mass

Question 2

what is a treatment goal for rehabilitation during the acute inflammatory response phase of an injury

Answer 2

prevention of new tissue disruption

Question 3

what is the primary goal of strength and conditioning in the subacute phase of healing

Answer 3

prevent muscle atrophy and deconditioning

Question 4

what component does agility include that is not part of speed

Answer 4

perceptual-cognitive ability

Question 5

which healing phase begins 3 weeks after the injury with the development of the fibrous scar and can continue for 6months or longer depending on the extent of the wound. there is a decrease in vascularity and continued remodelling of scar tissue by simultaneous synthesis of collagen by fibroblast and lysis by collagenase of enzymes

Answer 5

maturational or remodelling phase

Question 6

the primary processes during this phase focus on the building of new tissue to fill the wound space. the key cell during this phase is the fibroblast, a connective tissue cell that synthesises and secretes the collagen, proteoglycans, and glycoproteins needed for wound healing. the final component if epithelialisation, during which epithelial cells at the wound edges proliferate to form a new surface layer that is similar to that which was destroyed by the injury

Answer 6

proliferative phase
