biomechanics
kinesiology
| Question | Answer |
|---|---|
| what is kinesiology? | the scientific study of human movement and involves studying skeletal framework, structure of muscles and function, actions of joints, and the neuromuscular basis of movement |
| three important purposes for the study of kinesiology=? | safety,effectiveness, efficiency |
| what does kinesiology prepare for | teaching fundamental motor skills, and special sport skills |
| what is biomechanics? | a sub-discipline focuses on the application of the scientific principles of mechanics to understand movements and actions of human bodies and sports implements |
| what does a biomechanist do? | study how forces affect human motion and how movements can be improved |
| who is the father of biomechanics and when did it modernize | Borelli, 60's |
| what was the order of Wilkersons era and explain each | Kinesiology era where kinesiology was referred to as the application of mechanics to study movement, organization of subdiscipline (biomechanic era) and last development biomechanics |
| guidlines standards for undergrad biomechanics and kinesiology? | understand human body and external force for movement, knowledge undertake systematic approach to analysis motor skills, experience applying knowledge to evaluate both performer and performer in clinical/ educational mileu |
| what allowed for kinesiology and biomechanics to grow? | societies and forums that spread information |
| what is the future of bio-mechanics directed at? | strengthen improve movement for all in a variety of tasks |
| what should excersise be based on? | physiological and bio mechanical principle |
| explain the benefits of knowing rehab biomechanics | helps understanding how injury or disability has altered normal movement patterns. |
| what are the two main areas of study in biomechanics? | biology including bones, muscle nerves 2=mechanics of motion and newtons laws |
| velocity | speed and direction of a body and involve change of position of a body per unit of time |
| acceleration? | change in velocity |
| angular velocity | the angle rotated in a given time unit (rPM) |
| angular acceleration | change of angular velocity |
| mass? | the amount of matter possessed by an object? |
| what is force? | any action that changes or tends to change the motion of an object |
| pressure | the ratio of force to the area over which the force is applied |
| gravity | a natural force that pulls all objects toward the center of earth |
| center of gravity | center of mass |
| friction and its value | force when surface contacts and moves past one another and deals with traction and shoe design |
| work= | force that is applied to a body through a distance and in direction of force |
| power | the amount of work accomplished in one unit of time |
| energy= | capacity of a body to do work |
| torque | twisting turning, or rotary force related to the production of angular acceleration contrasted with force necessary to produce linear acceleration |
| what is the body's ability to return to a position of equilibrium after it has been displaced | stability |
| three principles | lower center of gravity toward base=more stable, nearer center of gravity to base=more support, the wider the base the greater stability |
| linear motion | motion from point to point in a straight line |
| rotary motion | movement of a body about an axis |
| newton | motion stays in motion, change in velocity proportional to force and inverse mass, every action has an equal opposite reaction |
| what is a lever? | a mechanical device used to produce a turning motion about a fixed point called an axis |
| what is a fulcrum | the center or axis |
| what is a force arm? | the distance from the fulcrum to the point of application force |
| first class | lever fulcrum located between the weight and point of application force (strength and speed) |
| second class | lever the weight is between fulcrum and force (force) |
| third class lever | the force is between the fulcrum and the weight (range of motion/ speed) |
| how do you make a lever with more force or for more speed/ ROM | length for force, shorten for speed/ ROM |
| force | the effect that one body has on another |
| stroboscopy? | an older photographic technique that can still be used to study human filming against dark background with light flashed on to compare execution |
| anthropometry | measurement of human body |
| chronoscopes | record speed of body movements |
| electrogoniometry | provides information about the angles of the joint as part of a total motion pattern |
| dynamography | technique used to measure forces produced during a movement |
| telemetry | involves wireless recording of various aspect of movement |
| biofeedback | provision of information about physiological parameter, such as muscle tension, to an individual |
| knudson four step approach | preparation, observation, evaluation/ diagnosis intervention |
| give an example of explaining how a force can accelerate a body that is already moving | when hitting a pitch, a faster pitch can be hit farther |
| explain the difference between mass and weight | mass is the amount of matter a body posseses while weight is the force gravity exerts on a body which is why gravity changes in space but mass stays the same. |
| kinematics | the study of the appearance of motion |
| kinetics | the study of forces acting on a body which explains the appearance of the movement |
| displacement | the change in position of a body with respect to a given direction |
