Question 1

What are the prime movers at the elbow during the down phase of the pull-up?
1) triceps brachii
2) biceps brachii
3) anconeus
4) brachialis
5) brachioradialis

A) 1, 3
B) 2, 4, 5
C) 1, 4, 5
D) 3, 4, 5

2, 4, 5

Accepted Answer

During the down phase of a pull-up, the muscles involved are primarily responsible for controlling the descent by eccentrically contracting. The biceps brachii, brachialis, and brachioradialis are the prime movers in this phase, as they control elbow flexion.

Question 2

Why lift a heavy weight by flexing and then extending the knees rather than flexing at the hips and then lifting the trunk?&#10;A) longer lever&#10;B) less force available&#10;C) shorter resistance arm&#10;D) smaller angle of pull

Accepted Answer

When lifting a heavy weight, it is more efficient to use the knee extension as it shortens the resistance arm, which requires less force to lift the weight. Flexing at the hips and then lifting the trunk would create a longer resistance arm and require more force to lift the same weight.

Question 3

What should one do to apply maximum pushing force?
1) use the largest possible number of segments
2) use the smallest segments
3) move through a large range of motion
4) move the segments in an ordered sequence, one after the other

A) 1, 2, 3
B) 1, 3, 4
C) 1, 3
D) 2, 4

1, 3

Accepted Answer

Using the largest possible number of segments may actually decrease pushing force because it spreads the force out over more segments. Using the smallest segments may limit the range of motion and decrease overall force. Moving through a large range of motion allows for maximum force generation. Moving segments in an ordered sequence may not necessarily increase force. Therefore, only choices 1 and 3 are valid, making option C the best choice.

Question 4

Which of the following is the prime mover in elbow extension during the up phase of the pushup?&#10;A) biceps brachii&#10;B) pectoralis major&#10;C) triceps brachii&#10;D) brachialis

Accepted Answer

The triceps brachii muscle is the primary mover in elbow extension during the up phase of the pushup. The biceps brachii, pectoralis major, and brachialis muscles are not involved in this action.

Question 5

Which of the following motions should be avoided in working with long handled implements?&#10;A) lifting&#10;B) pulling&#10;C) pushing&#10;D) twisting&#10;Short Answer Questions

Accepted Answer

Twisting motions should be avoided when working with long-handled implements because they can lead to strain and injury, especially in the back and torso areas.

Question 6

Question 7

Which is an example of the continuous application of a simultaneous pattern?&#10;A) a volleyball set&#10;B) landing from a jump&#10;C) pushing a lawn mower&#10;D) putting a shot

Accepted Answer

Pushing a lawn mower is an example of continuous application of a simultaneous pattern. This is because the movement requires the use of both arms and legs in a coordinated pattern for an extended period of time. The motion needs to be continuous, rather than intermittent, in order to achieve the desired result of mowing the lawn evenly. The other options may involve some simultaneous movement, but are not necessarily continuous patterns.

Question 8

Which would be the most efficient manner in which to lift a heavy box?&#10;A) grasp box at arms length&#10;B) face box with elbows bent and arms close to body&#10;C) turn side to box and lift with one arm&#10;D) place one hand under box and one hand on top at arms length

Accepted Answer

Lifting a heavy box with elbows bent and arms close to the body allows for the use of the larger muscles in the legs and trunk, reducing strain on the smaller arm muscles and minimizing the risk of injury.

Question 14

Which of the following is not true when attempting to produce a motion for maximum accuracy?&#10;A) use the fewest number of segments&#10;B) use the smallest segments possible&#10;C) use maximum possible contact time&#10;D) use the highest possible velocity

Question 15

Which of the following will not act to increase the force available in a pushing or pulling motion?&#10;A) applying all forces in sequence&#10;B) applying all forces along the line of action&#10;C) involving the lower extremity&#10;D) using the body weight when possible
