Q

Drawbacks of muscle biopsy 3

A

invasive
a small sample of the muscle may not be representative of the entire muscle
this technique has never been validated

17
Q

4 reasons to use the Wingate test

A

reliability
validity
specificity
sensitivity

18
Q

Also called peak power

A

anaerobic power

19
Q

energy systems used for anaerobic power

A

ATP PC system

20
Q

The highest work perfomed durning any 5 second period is known as this

A

Anaerobic power

21
Q

Formula for AP

A

max number of revs in 5 seconds X 6 meters/rev x Kg

Kg = (0.075 Kg resistance x Kg of body weight)

22
Q

converting AP from Kg x m x 5 sec^-1 to watts

A

(Kg x m x 5 sec ^-1) x 12/6.12

23
Q

the amount of power during the total 30 second work bout is

A

anaerobic capacity (AC)

24
Q

Anaerobic capcity (AC) is also known as

A

mean power

25
Q

Anaerobic capacity (AC) represents this

A

the ability to sustain power

26
Q

energy systems used for anaerobic capaicty

A

ATP PC system and anaerobic glycolysis

27
Q

Formula for AC

A

total number of revs in 30 seconds X 6 meters/rev x Kg

Kg = (0.075 Kg resistance x Kg of body weight)

28
Q

converting AC from kg x m x 30 sec^-1 to watts

A

(Kg x m x 30 sec^-1) x 2/6.12

29
Q

Fatigue index (FI) does this

A

gives insight on OXIDATIVE CAPACITY, but is not an actual measure of oxidative capacity

30
Q

fatigue index (FI) is also called this (2)

A

percent decline
power decline
from initial to end of the test

31
Q

Formula for FI

A

((highest 5sec work - lowest 5sec work) / (highest 5sec work)) x 100

32
Q

the measure we are getting is repeatable from one time to the next

A

reliability

33
Q

What is the r of the wingate test

A

r = 0.95 to 0.98

34
Q

describe 1 RM vs AP graph

A

positive linear slope

35
Q

describe 10 m dash times vs AP

A

negative linear slope

36
Q

describe shoe size vs AP

A

0 slope (flat line)

37
Q

test measures what it is suppose to measure

A

validity

38
Q

Allows us to make distinctions, or distinguish between endurance and power athletes

A

specificity

39
Q

sensitive to training adaptations and is good for pre- vs post-training comparisons

A

sensitivity of the wingate test

40
Q

describe the power output vs time graph

A

goes up at first then goes down.

The faster the slope goes down the more anaerobic the athlete

41
Q

% fast twitch =

A

(FI - 19) / 0.5

42
Q

how to calculate least power output

A

same as AP only use the least revs in 5 second period
