Program Design for Speed & Agility Training Flashcards
The skills and abilities needed to achieve high movement velocities
Speed
The skills and abilities needed to explosively change direction, velocities, or modes
Change of direction
The skills and abilities needed to change direction, velocity, or mode in response to a stimulus
Includes a perceptual cognitive component
Agility
What is the difference between speed and velocity?
Speed = how fast an object is moving
Velocity = how fast an object is moving + the direction
The development of maximal force in minimal time, typically used as an index of explosive strength
Rate of force development (RFD)
The product of the force generated x the time required for its production
Dictates the magnitude of change of momentum of an object
Impulse
Mass of an object x object velocity
Momentum
Are ground contact times longer or shorter during the acceleration phase compared to the maximal velocity phase of a sprint?
Longer contact times in the acceleration phase
How does strength training enhance the neural component of sprinting?
Enhances neural drive by increasing the rate and amplitude of neural impulses being sent from the nervous system to the muscles
How does the stretch shortening cycle contribute to speed/sprinting?
Rapid eccentric contraction (lengthening of the muscle) during the braking phase helps to produce a greater following concentric contraction
What is complex training?
Alternating SSC exercises (plyos) with heavy resistance exercises to enhance their effect
Which two variables will increase sprinting speed?
Increase in stride length and increase in stride rate
Elite sprinters have ___stride length and ____stride rate compared to novice sprinters
Greater stride length and rate
In elite sprinters, is stride length longer or shorter in the acceleration phase compared to the maximal velocity phase?
Stride length is shorter
Are vertical or horizontal forces primarily responsible for displacing the body forward during sprinting?
Vertical forces
