Seven Principles of Biomechanical Analysis
Transcript of Seven Principles of Biomechanical Analysis
Biomechanical Analysis The foundation to exercise Angular momentum Reaction Torque Impulse Stability Maximum Velocity Maximum Effort Principle 2: The pruduction of maximum force requires the use of all possible joint movements that contribute to the task's objective. Principle 4: The greater the applied impulse, the greater the increase in velocity. Principle 5: Movement usually occurs opposite that of the applied force. Principle 6: Angular motion is produced by the application of a force acting at some distance from an axis, that is by torque. Principle 7: Angular momentum is constant when an athlete or object is in the air. Principle 1: The lower the center of mass, the larger the base of support, the closer the center of mass to the base of support, and the greater the mass, the more stability increases example: shows how a ball-carrier (running back)has to adjust his stability to fend off an opposing tackler. example: Weigh lifting uses all joints possible to achieve the maximum force for the objective. principle 3: The production of maximum velocity requires the use of joints in order - from largest to smallest. example: Slapshot in hockey. example: gymnast pushing off vault. Force downward, movement upward. example: Football tackle, where the objective is to knock the opponent off his/ her center of mass, thereby causing a loss of balance. example: Gymnasts using closed position (tuck) or opened (layout) to apply inertia, therefore increasing and decreasing the rate of rotation.
