Chapter 13: injury prevention for the athlete

Question 1

warm up physiological outcomes increase

Answer 1

peripheral blood circlation
soft tissue elasticity
synovial lube of joints
oxygen uptake kinetics
adensosine trip turnover
muscle cross bridge cycling rate
muscle fiber conduction velocity

Question 2

warm up physiological decreases

Answer 2

visocity of the inter membranous lubes

cardiac trauma from sudden/sternuous exercise

Question 3

active warm up

Answer 3

any submaximal activity that facilitates a 1 celsius increase in the bodys internal core temp

Question 4

transition phase

Answer 4

time between the end of warmup and the start if the workout activity. 5-10mins between

Question 5

wwarmup stratagies include

Answer 5

submax/non fatiguing activity
stretching
sport specific movements
injury prevention techniques
gradual progression in the intensity level and movement specificity for the activity
increase in speed from half temp to game pace by the conclusion of the warm up

Question 6

common foot injuries

Answer 6

achilles tendonitis- inflammation of this tendon or its sheath

plantar fasciitis- inflammed and irritated plantar fascia, common cause of heel pain

metatarsal stress fractures- most common is 2nd and 5th metatarsal

Question 7

ankle sprains

Answer 7

most common sports injury, and number 1 for time lost
lateral ankle sprain is the most common type
47-73% of people who sprain their ankle will resprain it

Question 8

lateral ankle sprain

Answer 8

any of lateral ligaments could be injured including: talofibular ligament(ATFL), calcaneofibular ligament(CFL), and posterior talofibular ligament(PTFL)
ATFL is most common amongst lateral ankle sprains
mechanism of injury is forced plantar flexion and inversion of the ankle during landing on an unstable or uneven surface

Question 9

medial ankle sprains

Answer 9

involve the deltoid ligament of the ankle and amy include avulsion fractures of the tibia or other foot bones
mechanism of injury is rapid eversion of foot

Question 10

Syndesmotic (high ankle) sprains

Answer 10

involves the distal tibiofibular joint proximal to the ankle

mechanism for injury includes external foot rotation, talar eversion in the ankle mortise and excessive dorsiflexion

Question 11

ankle injury prevention and rehab

Answer 11

restoring range of motion at the ankle in clsoe kinetic chain dorsiflexion throuh stretching
strengthening of the ankle musculature
functional activities( hoppin, lateral movements, cutting maneuvers)
progression in number of reps, speed, direction over the course of several weeks

Question 12

two common knee injuries

Answer 12

patellofemoral pain(PFP) and ACL sprains/tears

Question 13

Q angle

Answer 13

formed by a line drawn from the anterior superior iliac spine to the central patella and a second line drawn from central patella through the tibial tubercle

Question 14

non contact events responsible for ACL injury

Answer 14

planting and cutting, straight knee landing, one step landing with a hyper extended knee

Question 15

rotator cuff strains occur when

Answer 15

a muscle group is overexerted causing microdamage within the muscle belly and tendon resulting in immediate inflammation and decreased muscle function

Question 16

shoulder impingment

Answer 16

subacromial impingement syndrome (SAIS) is a common diagnosis broadly defined as compression of the structures that run beneath the coracoacromial arch

Question 17

impinged structures include

Answer 17

supraspinatus and infraspinatus tendons, the subacromial bursa and the long head of the biceps tendon
