16
Q

plyometric training targets this type of adaptation

A

power, not cardiovascular

17
Q

plyometric volume is typically expressed as this

A

number of repetitions and sets, or foot contacts per workout

18
Q

beginner volume

A

80-100 contacts

19
Q

intermediate volume

A

100-120 contacts

20
Q

advanced volume

A

120-140 contacts

21
Q

these types of plyometric drills are contraindicated in adolescents

A

depth jumps and other high intensity plyometrics

22
Q

inward movement of the knee

A

valgus

23
Q

for masters program design the program should include no more than this many low to moderate intensity exercises

A

5

24
Q

recovery time between plyometric training sessions for masters

A

3-4 days

25
Q

T/F: Upper body plyo, and resistance training should be done on the same day (and vice versa)

A

F, upper body plyo should be paired with lower body resistance training (vice versa)

26
Q

combination of high-intensity resistance training followed by plyometrics

A

complex training, be sure to provide sufficient recovery time

27
Q

T/F: aerobic training should be done before plyometrics

A

F, plyometrics should be completed first

28
Q

proper landing position for plyometrics

A

shoulders over the knees and knees over the toes

29
Q

previous recommendation for beginning plyometrics

A

squat 1RM should be 1.5 x bw

30
Q

this is considered a less obvious lower body plyometric requirement

A

balance

31
Q

maintenance of a position without movement for a given period of time

A

balance

32
Q

athletes weighing over this much should avoid high-volume, high-intensity plyometrics and depth jumps from heights greater than 18inches

A

220lbs

33
Q

maximum height at which a depth jump can effectively and safely be performed

A

48 inches

34
Q

recommended height for depth jumps

A

16-42 inches

35
Q

athletes who weigh over 220lbs should only do depth jumps from this height or less

A

18 inches

36
Q

appropriate work to rest ratio for plyometrics

A

1:5

37
Q

starting box height for depth jumps

A

12 inches

38
Q

suggested ball weight for upper body plyo, for all except depth push up

A

2lbs, (5lbs for depth pushup)

39
Q

suggested box height for starting box drills

A

6 inches
