A. Larger, longer
B. Larger, shorter
B. Larger, shorter
In upright sprinting, an athlete’s stride length is largely dependent on ___
A. Athletes flexibility
B. The amount of vertical force produced during the stance phase
C. Athletes stride rate
B.
Drills or tests that require the athlete to move rapidly in response to a stimulus such as a whistle, arrow, or opponent are best for measuring which of the following?
A. Change in direction
B. Agility
C. Acceleration
B. Agility
Select the aspect of training that requires additional emphasis when the aim is to improve change of direction ability
A. Strength
B. Eccentric strength
X. Reactive strength
B. Eccentric strength
The skills. And abilities needed to achieve high movement velocities
Speed
The skills and abilities needed to explosively change movement direction, velocities, or modes
Change of direction
The skills and abilities needed to change direction, velocity, or mode in response to a stimulus
Agility
___ requires the ability to accelerate and reach maximal velocity
Speed
___ is often associated with an athlete’s capacity to produce force, but it is important to understand that while high levels of max strength are desirable attributes in sport, sprint, change of direction, and agility events occur in periods that prevent athletes from producing and expressing their max strength
Strength
In order to execute movement techniques, athletes must apply ____-product of mass and acceleration
FORCE
There are two variables that describe force relative to the time available to produce force:
rate of force development
Impulse
The development of max force in minimal time, typically used as an index of explosive strength.
Rate of force development (RFD)
The product of the generated force and the time required for its production, which is measured as the area under the force-time curve
Impulse
____ represents the interaction of two physical objects
FORCE
Force is a vector quantity meaning that it has both ___ and ___
Magnitude (size) and direction
Velocity and ___ are often used interchangeably
SPeed
Speed is a scalar quantity, which means that it describes only how fast and object is moving
True
___ is the rate at which an object covers a distance
Speed
Like force, ____ is a vector quantity
Velocity
___ refers to the rate at which an object’s velocity changes over time
Acceleration
The length of time athletes are in this stance or plant phase is termed ____ ___ ____
Ground contact time
____ is defined as the relationship between the mass of an object and the velocity of movement
Momentum
Strength training enhances _____ drive, the rate and amplitude of impulses being sent from the nervous system to the target muscles.
Neural drive
Research has shown that the combination of strength, plyo, and sprint training produces several adaptations within the neuromuscular system that may contribute to improved sprint performance.
True
Many functional tasks begin with prep counter movements involving spring like actions referred to as the ____ shortening cycle which is an eccentric concentric coupling phenomenon in which muscle tendon complexes are rapidly and forcibly lengthened
Stretch shortening cycle
STretch shortening cycle actions exploit two phenomena:
- Intrinsic muscle tendon behavior
2. Force and length reflex feedback to the nervous system
___ training, in which alternating SSC task with heavy resistance training within the same session enhances their working effect
Complex training
___ is a series of coupled flight and support phases known as strides orchestrated in an attempt to displace the athletes body down the track at maximal acceleration or velocity usually over brief distances and durations
Sprinting
Sprint speed can be increased by an increase in stride ___ and stride ____
Stride length
Stride frequency
Speed drills:
A- skip
Fast feet
Sprint resistance: incline for acceleration
Agility drills:
Deceleration drill
Z-drill
Agility drill Y shaped
