Sports Ergonomics
- Individual factors that
effect performance in sport
- Age
- Strategy
- Motiation
- Reaction Times
- Agility/Mobility
- Anthropometry/Somatatype
- Ectomorph
- Narrow-shaped body with little fat or muscle.
Ideal body type for long-distance runners.
- Endomorph
- Pear-shaped body, wide hips, wide shoulders, can have a lot fat on body,
arms and thighs. When fit, ideal body type for weightlifting, wrestling
- Mesomorph
- Wedge-shaped body, wide shoulders, narrow
hips, muscular. Ideal body type for sprinters.
- Aerobic/Anarobic
Capacity
- Gender
- Technique
- Muscle strength/type
- Mechanical efficiency in task
- Measuring metabolic rate for an activity
- Need to know Skin area: A = 0.202W0.425H0.725
W=Weight (Kg) and H=Height (m)
- Need to know metabolic rate for activity (table)
- Metabolic rate (in Kcals/hour) = 50*Number of Mets*A
- Aerobic Capacity
- Aerobic power- the highest level of oxygen
consumption an individual can attain
(VO2Max)
- 75% genes, 25% training
- Population av. 40 ml/Kg/min
- Athletes >70 ml/Kg/min
- Measured in progressive steps
until voluntary exhaustion
- Lactate threshold- a point in exercise when blood
lactate levels start to increase from baseline
- Lactate turnpoint- point in exercise when
blood lactate levels increase dramatically
- Equipment factors that effect
performance in sport
- Implements
- Extension of human limbs
- Material Properties
- Weight - golf club
- Stiffness - pole vault
- Toughness - bobsled
- Damping - tennis racket
- Fatigue resistance - mountain bike
- Surfaces
- Natural
- Synthetic
- Clothing/Shoes
- Performance Enhancing
- Aerodynamic fit (swimsuit-too efficient?)
- Freedom of movement
- Need for heat loss/gain
- Protecting
- Visibility
- Fire Protection
- Repellence of water/rain
- Air permeability
- Shoe design
- Performance issues: Weight,
Cushioning, Lateral support,
Heal/toe ratio,Grip
- Barefoot running shoes
- Highly cushioned running shoes are a
relatively recent design development
- Footstrike patterns: Heel,
Midfoot, Forefoot
- A- running with shoes, B-Barefoot running (no initial
peak impact forces- potential injury causer)
- Shoes change our natural mechanic, creating mechanical changes that are
not optimal for running fast (decreased stride frequency, increased ground
contact, decreased stiffness of the system, decreased elastic contribution
