Biomechanics Flashcards
Uses of bio mechanical analysis
Improvement of sports skills equipment Design of sports equipment Prevention of injuries Clinical analysis of movement pathologies Design of prostheses Design of rehabilitation
Biomechanics
The application of mechanical laws to living structures specifically to the locomotor system of the human body
Qualitative analysis
Non numerical description of movement based on direct observation. Conducted primarily by teachers n coaches
Quantities analysis
Movement analyzed numerically based on measurements frm data collected during performance of movement. Conducted by researchers
Mass
Quantity of matter contained in an object kg
Force
Mass x acceleration Newtons
Weight
Amount of gravitational force exerted on q body mass x acceleration of g newtons
Volume
Amount of space body occupies
Pressure
Force distributed over given area
N/cm^2
P= f/A
Compression
Pressing or squeezing force directly axially thru a body
Tension
Pulling or stretching force directly thru axially thru a body
Shear
Force directed parallel to surface
Mechanical stress
= f/a similar to pressure
Lifting heavy object
Get help.
Feet flat on floor shoulder width pointing straight ahead don’t slip
Face object in direction u intend move to avoid twisting torques
