Chapter 19 Speed And Agility Training Flashcards
Define speed
The skills and abilities needed to achieve high movement velocities
Define change of direction
The skills and abilities needed to explosively change movement direction, velocities, or modes 
Define agility
The skills and abilities needed to change direction, velocity or mode in response to a stimulus 
What is rate of force development?
The development of maximal force and minimal time typically used as an index of explosive strength
What is the product of the generated force in the time required for its production?
Impulse
What relationship describes impulse dictating the magnitude of change of momentum of an object?
Impulse-momentum relationship
What is the length of time athletes are in the stance or plant phase?
Ground contact time
What is the product of the time the force is applied to the ground and the amount of force applied?
Impulse
Define momentum
The relationship between the mass of an object, and the velocity of movement 
What is the production of braking forces over certain periods of time?
Braking impulse
What is complex training?
Alternating SSC tasks with heavy resistance exercises within the same session
What is postactivation potentiation?
Results from complex training
What is the mathematical model that depicts sprinting as a type of human locomotion in which the displacement of a body mass is the aftereffect from energy produced and is delivered through the collective coiling and extension of springlike actions within muscle architecture?
Spring-mass model (SMM)
What two characteristics of stride do elite sprinters have over novice sprinters?
Stride length and stride rate
What may be the most critical component of improving speed?
The amount of vertical force applied to the ground during the stance phase in the shortest time
