1

plyometric

high-intensity movements, such as jumping, involving high-force loading of body-weight during the landing phase of the movement that takes advantage of the stretch-shortening cycle

2

regressions

offering participants ways of modifications to decrease intensity and complexity

3

progressions

systematic process of applying overload like adding more resistance

4

range of motion (ROM)

number of degrees that an articulation will allow one of its segments to move

5

adherence

the extent to which people regularly follow an exercise program

6

rehearsal moves

moves that mimc an upcoming conditioning exercise usually done during the warm-up phase

7

neuromuscular efficiency

ability of the neuromuscular system to allow muscles that produce movement and muscles that provide stability to work together synergistically as an integrated functional unit

8

tendon

a band of fibrous tissue forming the termination of a muscle and attaching it to the bone

9

ligament

connects bones together

10

lactic acid

a metabolic byproduct of anaerobic glycolysis; when it accumulates it decreases blood pH and slows down enzyme activity and causes fatigue

11

delay fatigue

the decline in ability of a muscle to generate force

12

ratings of perceived exertion (RPE)

a scale that provides a standard means for evaluating a participants perception of exercise effert

13

stretch reflex

an involuntary motor response that, when stimulated, causes a suddenly stretched muscle to respond with a corresponding contractaction

14

muscle spindles

the sensory organ within a muscle that is sensitive to stretch and thus protects the muscle against too much stretch

15

Golgi Tendon Organs

a sensory organ within a tendon, that when stimulated, causes an inhibition of the entire muscle group to protect against too much force

16

Specificity

exercise training principle explaining that specific exercise demands made on the body produce specific response by the body
physiological changes caused by training are specific to performed activities

17

progressive overload

gradual increase of physiological stress placed on the body during a program of exercise training

18

Reversibility

principle of exercise training that suggests that any improvement in physical fitness due to physical activity is entirely reversible with the discontinuation of the training program

19

Four Components of Physic Fitness

Muscular Fitness, Cardiovascular Endurance, Flexibility, Body Composition, Mind Body Vitality (sometimes included)
