NSCA CSCS - Chapter 19

Question 1

Acceleration

Answer 1

The rate at which an object’s velocity changes over time

Question 2

Agility

Answer 2

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

Question 3

Change of direction

Answer 3

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

Question 4

Complex training

Answer 4

Training methodology involving high-intensity resistance training followed by plyometrics

Question 5

Force

Answer 5

Vector quantity representing a “push” or “pull” relationship between two objects that results in acceleration

Question 6

Ground preparation

Answer 6

Phase of sprinting where the stance leg drives down into the ground

Question 7

Impulse

Answer 7

The product of the magnitude of force applied and the duration of force application

Question 8

Momentum

Answer 8

The relationship between the mass of an object and the velocity of movement

Question 9

Periodization

Answer 9

Strategic manipulation of athlete’s preparedness through sequences training phases defined by cycles and stages of workload

Question 10

Postactivation potentiation

Answer 10

Increased force production capability in muscles from recent previous activity

Question 11

Rate of force development (RFD)

Answer 11

A measure of the time it takes to produce force, often used as an index for explosive strength

Question 12

Recovery

Answer 12

Phase of sprint where the swing leg is brought forward for the next stride

Question 13

Speed

Answer 13

Scalar value of the rate an object covers a distance

Question 14

Spring-mass model (SMM)

Answer 14

Model of sprinting that views sprinting as the compression of springs in the body (ankles, knee, and hip joints) followed by rapid expansion to produce force and displace the body down the track

Question 15

Sprinting

Answer 15

A series of coupled flight and support phases orchestrated in an attempt to displace the athlete’s body down the track at maximal acceleration or velocity

Question 16

Strength

Answer 16

The ability of the body and muscles to produce force

Question 17

Stretch-shortening cycle (SSC)

Answer 17

Cycle of rapid stretching of muscles and tissues followed by rapid mechanical and neurological contraction of the tissues - generally thought to be a combination of elasticity of joints and muscles and the stretch-reflex response

Question 18

Velocity

Answer 18

Vector quantity that describes the speed and direction an object is moving - can be positive or negative
