Chapter 19: Speed, Agility, and Quickness Training Concepts

Question 1

Speed

Answer 1

The ability to move the body in one intended direction as fast as possible.

Question 2

Agility

Answer 2

The ability to start (or accelerate), stop (or decelerate and stabilize), and change direction in response to a signal or stimulus quickly while maintaining postural control.

Question 3

Quickness

Answer 3

The ability to react and change body position with maximal rate of force production, in all planes of motion and from all body positions, during dynamic activities.

Question 4

Stride rate

Answer 4

The number of strides taken in a given amount of time (or distance)

Question 5

Stride length

Answer 5

The distance covered with each stride during the gait cycle.

Question 6

Frontside mechanics

Answer 6

Question 7

Backside mechanics

Answer 7

Proper alignment of the rear leg and pelvis during sprinting, which includes ankle plantarflexion, knee extension, hip extension, and a neutral pelvis.

Question 8

Bone density

Answer 8

Question 9

Osteopenia

Answer 9

Lower than normal bone density and a precursor to osteoporosis.

Question 10
