An isometric muscle action is characterized by the production of force:
  1. As a muscle lengthens due to extension of a joint.
  2. Through movement generated in opposition to the downward pull of gravity.
  3. As a muscle shortens due to flexion of a joint.
  4. Through tension and muscle contraction without movement.
22.
When a baseball or tennis player swings a bat or racket, the greatest amount of force will be delivered to the ball at impact when:
  1. The player avoids stretching the shoulder muscles during the backswing.
  2. The angular velocity of the swinging implement is as fast as possible.
  3. The player reduces the speed of the strike just before impact with the ball.
  4. The linear motion of the swinging implement remains level throughout the strike.
23.
During a backhand disc throw, keeping the back of the hand parallel with the ground and releasing the disc flat rather than at an angle are techniques used to:
  1. Generate an S-shaped pathway.
  2. Make the disc fly farther.
  3. Generate a sudden drop at the end of the flight.
  4. Make the disc skim the ground.
24.
During an adolescent growth spurt in which a student's arms and legs grow longer, the proportion of limb-to-torso-length often changes, resulting in:
  1. Significant increases in joint flexibility.
  2. Periods of poor coordination and balance.
  3. Significant decreases in connective tissue elasticity.
  4. Immediate improvement in technical skill and control.
25.
One important reason why a toddler learns to run several months after learning to walk is because in comparison to walking, running:
  1. Is a complex motor skill rather than a fundamental motor skill, and thus requires refinement.
  2. Is less stable and requires development of greater motor control and coordination.
  3. Requires one foot to be always in contact with the ground, which is difficult for toddlers to master.
  4. Involves supporting body weight in all phases, and thus requires additional strength.
