速度训练

Speed  is the capacity of an individual to perform a
motor skill as rapidly as possible. Speed is an integral
component of sport. For example, linear running speed
may be defined by its three distinct phases: (a) accel-eration, (b) maximum speed, and (c) deceleration. The
acceleration  phase is characterized by an increase in
speed, and is reliant upon strength, power, and reaction
time. The  maximum speed phase is characterized by the
individual’s attainment of his or her fastest speed and
how long he or she can maintain it,  e.g., speed endur-ance. The deceleration  phase is a result of fatigue and is
characterized by the individual involuntarily decreasing
speed after maximum speed has been attained. Speed
may be enhanced by a combination of methods includ-ing nonassisted and assisted sprint training, strength
and power training, plyometrics, technique training,
and sport-specific practice.
