Lab Test 1 (lab 2) Flashcards
The wingate test determines this
anaerobic work indices
Anaerobic ability is defined as
ability to perform short term bursts of high intensity work
4 measures of anaerobic capabilities
10-40 meter dash
margaria power test
muscle biopsy
wingate test
Power =
work / time
work =
force X distance
higher 40 meter dash times mean this
less power
shorter 40 meter dash times mean this
more power
energy systems involved in a 10-40 meter dash
ATP PC system or phosphagen system
9-step test that measures time and vertical distance traveled and plugs it into a regression equation
margaria power test
What do you do to determine fiber type content during a a muscle biopsy
use biopsy needle to take sample
stain sample with SDH and myosin ATPase reactants
Drawbacks of muscle biopsy 3
invasive
a small sample of the muscle may not be representative of the entire muscle
this technique has never been validated
Bar-Or developed this maximal, cycle ergometer test at this institute
Wingate test
Wingate
This is a confounding factor of the wingate test
body weight
The wingate test met the need for a simple, inexpensive, repeatable, specific, reliable, and valid test: T/F
T
The wingate test is invasive T/F
F
3 work indices obtained from the wingate test
anaerobic power (AP) Anaerobic capacity (AC) Fatique index (FI)
4 reasons to use the Wingate test
reliability
validity
specificity
sensitivity
Also called peak power
anaerobic power
energy systems used for anaerobic power
ATP PC system
The highest work perfomed durning any 5 second period is known as this
Anaerobic power
Formula for AP
max number of revs in 5 seconds X 6 meters/rev x Kg
Kg = (0.075 Kg resistance x Kg of body weight)
converting AP from Kg x m x 5 sec^-1 to watts
(Kg x m x 5 sec ^-1) x 12/6.12
the amount of power during the total 30 second work bout is
anaerobic capacity (AC)
Anaerobic capcity (AC) is also known as
mean power
Anaerobic capacity (AC) represents this
the ability to sustain power
energy systems used for anaerobic capaicty
ATP PC system and anaerobic glycolysis
Formula for AC
total number of revs in 30 seconds X 6 meters/rev x Kg
Kg = (0.075 Kg resistance x Kg of body weight)
converting AC from kg x m x 30 sec^-1 to watts
(Kg x m x 30 sec^-1) x 2/6.12
Fatigue index (FI) does this
gives insight on OXIDATIVE CAPACITY, but is not an actual measure of oxidative capacity
fatigue index (FI) is also called this (2)
percent decline
power decline
from initial to end of the test
Formula for FI
((highest 5sec work - lowest 5sec work) / (highest 5sec work)) x 100
the measure we are getting is repeatable from one time to the next
reliability
What is the r of the wingate test
r = 0.95 to 0.98
describe 1 RM vs AP graph
positive linear slope
describe 10 m dash times vs AP
negative linear slope
describe shoe size vs AP
0 slope (flat line)
test measures what it is suppose to measure
validity
Allows us to make distinctions, or distinguish between endurance and power athletes
specificity
sensitive to training adaptations and is good for pre- vs post-training comparisons
sensitivity of the wingate test
describe the power output vs time graph
goes up at first then goes down.
The faster the slope goes down the more anaerobic the athlete
% fast twitch =
(FI - 19) / 0.5
how to calculate least power output
same as AP only use the least revs in 5 second period
