A

Length-Tension Relationships

35
Q

Something that tends to produce rotation or torsion. The movement of a system or force that typically leads to a rotation.

A

Torque

36
Q

This is rotational movements from the joints.

37
Q

Groups of muscles that work with one another in order to produce a force on a joint.

A

Force Couple

38
Q

How the muscular and nervous system cooperates to gather and interpret information in order to execute the movement.

A

Sensorimotor Integration

39
Q

This is the cumulative sensory input to the CNS (Central nervous system) from all of the various mechanoreceptors that can sense limb movement and body position.

A

Proprioception

40
Q

Proprioception training improves ____, ____, and ____.

A

Coordination, posture, and balance

41
Q

Muscles that are controlled by the central nervous system in order to produce a movements.

A

42
Q

The maturation of muscle coordination.

A

Motor Development

43
Q

The process of improving one’s motor skills with practice. This results in lasting changes and one’s overall capability of responding.

44
Q

The process where people use cognition in order to coordinate the muscles and limbs of the body.

A

Motor Control

45
Q

Response to external and internal stimuli from the environment. The overall study of motor development, motor learning and motor control (a.k.a. movement).

A

Motor Behavior

46
Q

This is information that one will get about their performance from external sources. Usually visual, verbal or written.

A

External Feedback

47
Q

This is how you personally feel after you have practice or performed a certain skill.

A

Internal Feedback

48
Q

This is a biological system where the response or the output affects the initial input. Your sensory system gathers input from your motor system in order to adapt and learn new motor skills.

A

Feedback

49
Q

Where the fulcrum sits directly between the energy moving the weight and the weight itself. Some good examples are scissors, seesaws, crowbars or a hammer extracting a nail.

A

Type 1 Lever

50
Q

Where the fulcrum is at one end, the weight is in the middle and the force is being applied on the other end. Some common levers that use this type are wheelbarrows, can openers and staplers.

A

Type 2 Lever

51
Q

Where the fulcrum is on one end, the weight is on the other end and the forces being applied in the middle. With this type of lever, more force needs to be applied, but in return, the weight gets moved a much larger distance. Some good examples are a fishing rod, a broom or a baseball bat.

A

Type 3 Lever
