Chapter 9: Speed, Agility and Quickness Training Flashcards
Speed
the “rate of performance” of an activity
Linear speed
ability to move in one intended direction as fast as possible.
Stride rate
amount of time needed to complete a stride cycle; limited by stride length
Drive phase
point of stride when the foot first contacts the ground
Recovery phase
point of stride when the leg swings from the hip while the foot clears the ground.
Support phase
point of stride when the runner’s weight is carried entirely by the foot.
Over-speed (assisted) drills
running drills using an apparatus or downhill surface grade that assists in accelerating movement; athlete adapts to higher rates of acceleration.
Resisted speed drills
the athlete moves against increased horizontal or vertical load; improves running drive-phase force production and stride length.
Agility
ability to change direction or orientation based on rapid processing of internal or external information, accurately without significant loss of speed.
Multidirectional speed (MDS)
ability to create speed in any direction or body orientation.
Components of agility training
body control and awareness, recognition, and reaction starting and the first step, acceleration, footwork, change of direction, stopping.
Quickness
ability to execute movement skills in a comparatively brief amount of time.
Reaction time
time elapsed between an athlete’s recognizing the need to act and initiating the appropriate action.
Total response time
summation of the reaction time and the time it takes to execute the movement.
DRILLS FOR SPEED, AGILITY/MDS, and QUICKNESS:
Specialized strength exercises for speed
- Resisted knee drives • Supine heel pushes • Tube walking • Reverse calf raises • Superman
- Weighted arm swings • Towel pulls
