Which of the following principles best describes why individuals with large body builds tend to excel at physical activities that require a great degree of stability?
  1. Larger body segments tend to produce more force than smaller body segments.
  2. Muscles with large cross-sectional areas can produce more force than smaller muscles.
  3. A body's inertia, or resistance to change in a state of motion, is proportional to body mass.
  4. A body in equilibrium can be either stationary or moving at a constant speed in a given direction.
57.
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.
58.
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.
59.
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.
60.
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.
