Biomechanics
CH 1 What is bomechanics
Question | Answer |
---|---|
What is biomechanics? | The study of internal and external forces acting on the body segments, and the effects produced by these forces |
Internal force | muscle contractions and ligaments pulling |
External force | Weight, gravity, air resistance |
Do you run faster on a treadmill or track? | Treadmill because there is no air resistance |
Statics mechanics | Constant state of motion |
Dynamics mechanics | Acceleration present |
0 net force is what? | Static |
Kinematics | Actual movements. Study of variables that describe or quantify motion |
Kinetics | Causing motion. Study of variables that cause or influence motion |
sequential motion | the acceleration of body segment occurs sequentially, from proximal to distal fashion |
Occupational biomechanics | goal to designed machines that the workplace to REDUCE repetitive stress on workers |
Clinical biomechanics | analysis of the mechanics of injured patients and provide feedback to restore normal function |
Sports biomechanics | a quantitative based study and analysis of professional athletes and sports activities in general |
