What is Clinical and Sport Biomechanics |
the study of the human body at rest and in motion using principles and concepts derived from physics, mechanics, and engineering |
|
|
Static biomechanics |
examines bodies, masses, and forces at REST or moving at CONSTANT velocity |
|
|
dynamic biomechanics |
investigates bodies, masses, and forces when they are speeding up or slowing down (ACELERATION) |
|
|
Clinical Biomechanics |
improving the ability of an injuried individual to perform actives of daily living including work and lesure activities, physical activity or exercise |
|
|
Sport biomechanics |
applies the laws and principles of mechanics and physics to enhance sport performance through improvement in techniques and equipment |
|
|
Body Motion |
Linear Motion
Angular Motion
General motion |
|
|
Linear Motion |
all points of the body are moving in the same direction at the same speed and are traveling the same direction
(vertical jump, riding in a car, skiing, coasting on a bike) |
|
|
Angular Motion |
a rotary motion or rotation, is movement around a central imaginary line known as the axis
(single joint movement: knee, elbow, and head) |
|
|
General Motion |
Occurs when transition angular movements are combined
(Spinning, Walking) |
|
|
Mechanical sytems |
operating defining the system of interest |
|
|
Standard Reference Terminology |
Common and specific terminology that precisely identifies body positions and movement direction |
|
|
Joint Movement Terminology |
movements of bones and joints of the body |

|
Compressive (compression) force |
Force that tends to shorten or squeeze something decreasing its volume |
|
|
Tensile (Tension) Force |
a force that tends to stretch or elongate something |
|
|
Shear (Friction) force |
force acting on a substance in a direction perpendicular to the extension of the substance |
