ergonomic aids
Mechanical
Any physical object that affects performance
• Carbon bike frame
= Lighter
ergonomic aids
Psychological
- Techniques that support the athlete’s
mental state- Easy to learn/develop and implement
- Rituals (hypnosis/encouragement/imagery/music/relaxation)
ergonomic aids
Physiological
- Naturally occurring bodily substances, when increased to
higher-than- normal levels improve performance.
- Blood
doping (Illegal) – Increases
hemoglobin = more oxygen to muscles
- Blood
doping (Illegal) – Increases
ergonomic aids
Pharmacological
- Otherwise known as performance enhancing drugs (PEDs)
- Amphetamines
- Stimulate CNS for alertness and
energy by increasing BP, HR and blood to
muscle
- Stimulate CNS for alertness and
energy by increasing BP, HR and blood to
- Amphetamines
Creatine
- Increase creatine phosphate storage to help turn more ADP into
ATP to increase energy to muscle during intense exercise.
- Improvements in max force production, sprinting and jumping, aerobic endurance
Caffeine
- Aerobic endurance tends to be the most consistent with
moderate-to-large benefits
- Anaerobic and aerobic benefits in some sources
- 3-6 mg/kg body mass
Macronutrients
carbs
- 1g ~ 4 kcal
- Preferred energy source -> glucose -> simplest form of carb
- Help regulate blood sugar
Macronutrients
protein
- 1g ~ 4 kcal
- Help growth and repair of tissue, important for making hormones/enzymes
- Energy source when carbs are unavailable
Macronutrients
fats
- 1g ~ 9 kcal
- Help with vitamin absorption and energy storage
- Essential for body process
- Can be used as energy in low to moderate intensity activity
Factors Influencing Nutrition
- Age
- Body size
- Genetics
- Sex
- Environmental conditions
- goals
- cost
- time
Injury Risk Factors
- Hours of risk exposure
- Inadequate training
- Playing situation
- Player/opponent behavior
- Environmental factors
- Skill level
Types of Injuries
- Strains // Sprains
- Dislocation // Subluxation
- Contusion // Fractures
- Overuse
Strain
– an injury of overstress or tearing to musculotendinous tissue
Sprain
- an injury of overstress or tearing to ligamentous tissue
Grade 1 (Mild)
- overstressed with small tears in fibers,
- pain usually mild and swelling may be present
Grade 2 (Moderate)
- overstressed and a significant portion of fibers are torn, but
it is not a complete tear.
- pain, swelling and possibly bruising with limited function
Grade 3 (Severe)
- overstressed to the point of complete rupture,
- pain tenderness, bruising, swelling, gapping, limited mobility, (loss of strength due to lack of muscle attachment in strain)
Dislocation
- Joint is forced out normal positioning with adjacent joint surface
Subluxation
partial joint dislocation
Signs and symptoms (subbluxation+dislocation)
- Joint deformation
- Numbness or tingling at joint
- Swollen or discoloration
- Limited ROM
- Intense pain
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)
- Deformity/ visibly misshapen area
- Severe pain at or near the site
- Loss of force production/limited ROM
Overuse
Injuries that occur from tissue damage from repetitive demand over a period of time
Examples of overuse injuries
- Stress fractures
- Tendinitis/Tendinopathy
- Patella femoral pain syndrome
- Plantar fasciitis
Most Common injuries
- Sprains (ligamentous injuries)
- Strains (musculotendinous injuries)
- Contusions (bruising)
- Knee injuries
- Ankle sprains
- Lumbar strains
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)
- multiple sets 3−6 (12–28 sets/muscle/week)
- 6-12 reps
- Rest intervals (60s)
- Moderate intensity (60−80% 1RM) with PROGRESSION
Strength (sets/reps/weight)
- Periodized training programs and training to
failure elicit greater strength gains - Multiple sets ~ 4-8
- Low reps ~ 1-5
- Longer rest intervals ~ 2-5 mins
between
sets - Vigorous intensity 80-85+% of 1 RM
