1

What is biomechanics?

A study that uses principles of physics to quantitatively study how forces interact within a living body

2

What is force?

An influence applied to one object to another, which results in an acceleration or deceleration of the second object

3

What is rotary motion?

Movement of the bones around the joints

4

What is torque?

A force that produces rotation. Common unit of torque is the Newton-Meter or N.m.

5

What is motor behavior?

Motor response to internal and external environmental stimuli

6

What is motor control?

How the central nervous system integrates internal and external sensory information with previous experiences to produce a motor response

7

What is motor learning?

Integration of motor control processes through practice and experience, leading to a relatively permanent change in the capacity to produce skilled movements

8

What is motor development?

The change in motor behavior over time throughout the lifespan

9

What is proprioception?

The cumulative neural input from sensory afferents to the CNS

10

What is sensorimotor integration?

The ability of the CNS to gather and interpret sensory information to execute the proper motor reponse

11

What is feedback?

Internal feedback: sensory information provided by the body via length tension relationships, force couple relationships, and arthrokinematics to monitor movement and the environment
External feedback: information provided by some external source

12

What is Knowledge of Results?

Feedback used after the completion of a movement, to help inform the athlete about the outcome of his performance

13

What is Knowledge of Performance?

Feedback that provides information about the quality of the movement during exercise
