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 |
