C. Relationship between force and time

C. Relationship between force and time

2

Elite sprinters produce ___ forces in a ____ ground contact time as compared to their novice counterparts.
A. Larger, longer
B. Larger, shorter

B. Larger, shorter

3

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.

4

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

5

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

6

The skills. And abilities needed to achieve high movement velocities

Speed

7

The skills and abilities needed to explosively change movement direction, velocities, or modes

Change of direction

8

The skills and abilities needed to change direction, velocity, or mode in response to a stimulus

Agility

9

___ requires the ability to accelerate and reach maximal velocity

Speed

10

___ 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

11

In order to execute movement techniques, athletes must apply ____-product of mass and acceleration

FORCE

12

There are two variables that describe force relative to the time available to produce force:

rate of force development
Impulse

13

The development of max force in minimal time, typically used as an index of explosive strength.

Rate of force development (RFD)

14

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

15

____ represents the interaction of two physical objects

FORCE

16

Force is a vector quantity meaning that it has both ___ and ___

Magnitude (size) and direction

17

Velocity and ___ are often used interchangeably

SPeed

18

Speed is a scalar quantity, which means that it describes only how fast and object is moving

True

19

___ is the rate at which an object covers a distance

Speed

20

Like force, ____ is a vector quantity

Velocity

21

___ refers to the rate at which an object's velocity changes over time

Acceleration

22

The length of time athletes are in this stance or plant phase is termed ____ ___ ____

Ground contact time

23

____ is defined as the relationship between the mass of an object and the velocity of movement

Momentum

24

Strength training enhances _____ drive, the rate and amplitude of impulses being sent from the nervous system to the target muscles.

Neural drive

25

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

26

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

27

STretch shortening cycle actions exploit two phenomena:

1. Intrinsic muscle tendon behavior
2. Force and length reflex feedback to the nervous system

28

___ training, in which alternating SSC task with heavy resistance training within the same session enhances their working effect

Complex training

29

___ 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
