Q

Jake wants to begin a plyometrics training program, but his coach has advised him that in order to begin upper-body plyometric exercises, he must be able to bench press a minimum weight to be considered ready. Based on his personal information (height 6’2”, weight 190 lbs., 22 years of age), what is the minimum weight that Jake must bench press in order to be considered ready for upper-body plyometrics training?

A

285 pounds

A

120-140

22
Q

The correct order of the movement phases used in a power clean is

A

beginning position, first pull, scoop, second pull, catch

23
Q

Andrea finds that her athletes’ performance on the push-up test and the YMCA bench press test is not similar, even though both tests are designed to assess muscular endurance of the upper body. These tests appear to lack this type of validity.

A

concurrent

24
Q

plyometric volume for someone beginning a program

A

80-100

25
Q

plyometric volume for someone with some experience

A

100-120

26
Q

plyometric volume for someone with a lot of experience

A

120-140`

27
Q

what is the proper plyometric landing position

A

the shoulders are in line with the knees, which helps take the center of gravity over the bodys base of support

28
Q

If an athlete does low-intensity lower body resistant training on monday, what else should they do along with that on the same day?

A

high-intensity upper body

opposite on both

29
Q

what should be included in plyo warm-up drills

A

marching, jogging, skipping, footwork, lunging

30
Q

what factors affect the intensity of lower body plyo drills

A

points of contact
speed
height of the drill
body weight

31
Q

order of lower body plyo in intensity

A

jumps in place, standing jumps, multiple hops and jumps, bounds, box drill, dept jumps

32
Q

what happens during the eccentric(phase 1) of a plyo exercies

A

stretch of the agonist muslce (muscle spindles are stimulated) elastic energy is tored in the series elastic component

33
Q

what happens during the amortization (phase 2) of a plyo exercies

A

pause between phase 1 and 3
type la afferent nerves synapse with alpha motor neurons
alpha motor neurons trasmit signals to agonist muscle group

34
Q

what happens during the concentric (phase 3) of a plyo exercies

A

shortening of agonist muscle fibers
elastic energy is released from the series elastic component
alpha motor neurons stimulate the agonist muscle gorup

35
Q

what are the 3 types of balance test that have variations of either double or single leg

A

standing, quarter squat, and half squat

36
Q

what are the steps for implementing a plyometric program

A
evaluate the athlete
ensure that facilities and equipment are safe
establish sport-specific golas
determine programd design variables
teach the athlete proper techique
properly progress
