Injury Risk Factors
Types of Injuries
Strain
– an injury of overstress or tearing to musculotendinous tissue
Sprain
- an injury of overstress or tearing to ligamentous tissue
Grade 1 (Mild)
Grade 2 (Moderate)
Grade 3 (Severe)
Dislocation
Subluxation
partial joint dislocation
Signs and symptoms (subbluxation+dislocation)
Contusion
Region of injured skin and/or soft tissue where there have been ruptured capillaries (bruise)
Fractures
• Signs and symptoms
• Deformity/ visibly
misshapen area
• Severe pain at or near the site
• Loss of
force production/limited ROM
• Bone breaking due to excessive force or trauma
Signs and symptoms (Fractures)
Overuse
Injuries that occur from tissue damage from repetitive demand over a period of time
Examples of overuse injuries
Most Common injuries
Phases of Tissue Healing
• Inflammatory Phase
clearing pathogens bacteria and damaged cells, red, hot, swollen area
Phases of Tissue Healing
• Proliferation (Fibroblastic)
Phase
laying down new tissue, collagen
Phases of Tissue Healing
• Remodeling Phase –
strengthening tissue granulation tissue to form new epithelium
Hypertrophy (sets/rep/weight)
Strength (sets/reps/weight)
Strength
Periodized training programs and training to
failure elicit
greater strength gains
Hypertrophy
Combo of metabolic stress and mechanical tension
Strength REPS
<2-5
Power REPS
<2-5
Hypertrophy REPS
6-12
Muscular endurance REPS
13 - >20
