List 3 characteristics of force that must be identified in order to determine the kind of motion that will result.
Magnitude, direction, point of application.
100
Describe the relationship between the knee and the hip using anatomical directions
The hip is proximal to the knee.
100
List the three planes
Sagittal, frontal, transverse
100
Name the three muscles of the hamstring group.
Biceps femoris, semimembranosus, semitendinosus.
100
Would running be an example of a "discrete" or "continuous" task?
Continuous
200
If I am hitting a golf ball for maximal distance and the height of the landing area is below the height of the projection area, what adjustment should I make to the angle of release?
Decrease it.
200
Use anatomical terms to describe the relationship between the sternoclavicular and acromioclavicular joints.
SC is medial to AC.
200
Rotating your head to the left occurs in what plane?
Transverse.
200
What type of muscular contraction is primarily responsible for the reception of a hard thrown medicine ball?
Eccentric
200
Would a push-up be simultaneous or sequential in nature?
Simultaneous.
300
A body continues in its state of rest or of uniform motion unless an unbalanced force acts on it is Newton's law of __________.
Newton's law of inertia.
300
From anatomical position, turning your thumb toward your body would be best described as ___________.
Pronation.
300
Name a motion that occurs about/around the AP axis
AB/ADDuction, lateral trunk flexion
300
If I concentrically contract my left external oblique and right internal oblique muscles at the same time, the major motion that will be noted in the spine is...
Right rotation
300
Why is it easier for me to lift a given amount of weight on the leg extension machine if I move the resistance arm closer to my knee?
Decrease the moment (resistance) arm.
400
Describe the difference between the efficiency and the effectiveness of a movement.
Effectiveness is success or failure in meeting a movement goal. Efficiency is meeting that goal by expending as little energy as possible.
400
Medial and lateral rotation of the tibia occurs at what joint?
Tibiofemoral
400
Describe one motion that occurs in each of the three planes.
Describe why a ball which is struck with the barrel of a baseball bat will travel farther than a ball struck closer to the handle.
The farther it strikes from the axis of rotation, the greater the linear speed of the striking object.
500
Describe moment of inertia. List two things one can do to decrease it.
A body continues in a state of rest or uniform rotation about an axis unless acted upon by an external torque.
Decrease the mass. Decrease the distance of the mass from the axis of rotation.
500
Describe the relationship between the cuboid and the navicular bones using anatomical directions.
Navicular lateral to cuboid.
500
Describe one motion that occurs about/around each of the three axes.
Bilateral - flexion
AP - ABduction
Vertical - trunk rotation
