Chapter 19 Flashcards
(25 cards)
What is speed?
The ability to move the body in one direction as fast as possible.
What is agility?
The ability to change direction or speed in response to a stimulus.
What are the components of sprinting?
Acceleration, maximum velocity, and stride mechanics.
What is stride length?
The distance covered in one stride during sprinting.
What is stride frequency?
The number of strides taken per unit of time.
How can sprinting speed be increased?
By improving stride length and stride frequency.
What is the stretch-shortening cycle (SSC)?
A mechanism that enhances force production through elastic energy storage.
What are the phases of sprinting?
Start, acceleration, and top speed.
What body position is optimal during acceleration?
Forward lean with explosive hip, knee, and ankle extension.
What is the proper arm action during sprinting?
Arms swing from shoulder with elbows at 90 degrees.
What is change of direction (COD)?
Physical ability to change movement direction without reacting to an external stimulus.
What is perceptual-cognitive ability?
Skill to react to stimuli, make decisions, and anticipate movements.
What drills enhance agility?
T-test, pro agility, reactive drills, and cone drills.
What is the role of strength training in speed development?
Improves force output and neuromuscular efficiency.
What is the role of plyometrics in speed development?
Enhances explosiveness and SSC utilization.
What is sprint assistance training?
Methods like downhill running to increase stride frequency.
What is sprint resistance training?
Methods like sled pushes to improve acceleration.
What is the recommended frequency for speed training?
2–3 times per week.
What is the work-to-rest ratio for speed training?
1:5 to 1:6 or longer.
What is deceleration?
The ability to slow down or stop efficiently.
What is technique training?
Drills and instruction focused on improving movement mechanics.
What factors affect agility performance?
Speed, strength, coordination, balance, and reaction time.
How should agility be progressed?
From closed drills to reactive, open-skill situations.
What is dynamic correspondence?
The transfer of training effects to sport-specific movements.
