Prevention and Treatment of Exercise Injuries
I. Prevention of Injury -- Risk Factors
A. Poor/Proper Equipment -- safety, shoes, surface
1. Settings of the way the equipment is tuned to your body can be a
contributor to injury
2. What shoes you wear & what surface you exercise on
B. Poor/Proper Conditioning -- FITT-VP, rest, recovery
C. Poor/Proper Technique -- body mechanics, ROM
D. Lack of Awareness -- overtraining, rules, skill level
II. Treating Common Exercise Injuries
A. Acute and Chronic Injuries (Tbl 3.6)
1. Acute Injury
a) An event you can define
b) Sharp, localized pain
c) Most common are sprains & strains; includes fractures &
dislocations
(1) Sprain: Injury to a ligament -- bone to bone
(a) Overstretch/Tear Ligaments
(i) First Degree Sprain: Overstretching of the
ligaments (not too severe)
(ii) Second Degree Sprain: Partial tear of some
fibers
(iii) Third Degree Sprain: Total tear
(iv) Anterior cruciate ligament (ACL) -- knee
(a) Cruciate: Means cross
(v) Medial Collateral Ligament (MCL) [inside]
(vi) Lateral Collateral Ligament (LCL) [outside]
(vii) Posterior Collateral Ligament (PCL)
(viii) Ligaments have a very poor blood supply
(a) Recovery time is much longer
(2) Strain: Muscle tear
(a) Faster recovery
(b) Better blood supply
(3) Fractures & Dislocations
(a) Fracture = broken bone
(i) Hair line, very small
(ii) So clear or ends of bones are shattered
(b) Dislocation = 2 bones are out of place at the joint
that connects them
2. Chronic Injury
a) Overuse injury
b) Inflammation, nagging soreness
c) Hard to pinpoint time of injury
