Q

what is the fucntion of the wingate test

A

assess anaerbic capacity and fitness
assess physiological and cognitive responses to supra maximal exercise

Measures one’s ability to use

Q

how does anaerboic glycolisis allow for ATP production

A

without oxygen

probides ATP via the breakdown of glucose (glycolysis) and glycogen (Glycogenolysis) in the musclr)

Q

explain the immediate energy system

A

. Immediate energy
• Alactic System (ATP-PCr: adenosine triphosphate/ phosphocreatine)
• Fast pace, low yield (1 enzyme - 1 step) – 5 to 10 sec

18
Q

what percentage of the required atp comes from the ATP PCR and anerobic glycoltoci systems

A

80%

19
Q

what does more prolongued physical activaty require

A

a more effiecient and slower atp generating sysym

=OXIDATIVE GLYCOLUYSIS

20
Q

true or false: through training, anaerbic capcity can be increased

A

true

21
Q

what does peak anaerboic closely reflect and why

A

ability tto use the atp-pcr system (since peak usually ocrurs during first 5 seconds when ATP_Pcr is highly active)

22
Q

what is mean anaerobic an indicator of and why

A

of ones ability to use the anaerboic gkycolytic system since about 50% of energy supplied to working muslces furing test is by anerbic glycolysis anf glycogeneloysis)

23
Q

explain atop contribution in first 10 second

A

70% from immediate (Atp-pcr)

15% from short term system

24
Q

explain atp contribution during 30 seconds

A

30% from immediate

50% from anerobc glycol (Shory term)

25
Q

what is the equation ofr total work and what does it reflect

A

Total Work = F x d = (mass x acc.) x (# rev x 6m/rev)
= (load (kg) x 9.8) x (# rev x 6m/rev) (Nm or J)

= Reflects the overall anaerobic capacity

26
Q

what is the equstion for peak and what does it reflect

A

Peak-AnP = Power achieved in the best 5 second period of the test, typically the first 5 seconds
= work/time = work in best 5 sec / 5 sec (Nm/s = watts)

= Ability to use system A (immediate ATP PCR)

27
Q

what is the equation for mean anoerobic power and what it reflects

A

Mean-AnP = Power achieved over entire test
= Work (total) / time (total) (Nm/s = watts)

= Ability to use system B (anerobic glycolytic sysstem

28
Q

what is the equation for fatigue infex and what does it reflect

A

Fatigue Index =
= (Max An-P – Min An-P / Max An-P) x 100

=Reflects ability to maintian power output from anerboribc energy sysstsms

29
Q

true or false: *fatigue index is Only valid if max is “real” (full effort from the get-go)

A

true

30
Q

what is the formula for total energy expernditure in kcal

A

total work (nm) x 0.000239

31
Q

true or false : Male scores are 50% higher than females,

A

false
Male scores are 15-30% higher than females, which is
likely due to:

32
Q

what is the 3 reasons men usually score higher than women

A

1) Greater relative muscle area
2. Greater metabolic capacity of fast-twitch fibers
3. Longer catecholamine response (fight-or-flight;
epinephrine and norepinephrine)

33
Q

what can Difference among individuals’ relative scores can be
attributed to:

A
  1. Training
  2. Heredity / genetics
  3. Motivation
34
Q

what 2 bikes are used for the test

A

Monark cycle ergometer

Velotron cycle ergometer

35
Q

what is the resistance on the flywheel based on

A

subjects weight and experience with anerboic conditining

36
Q

what are some imporatnt thigs prior to the eingate

A
must sign informed consent
must complete GAQ
must be mentally prepared
should not eat before 
shuld be physically healthy (not sick in last 4 weeks)
37
Q

what time of the day is best

A

laate afternnoon

38
Q

what is the wingate proctocol

A

warm up 3-5 min: cycle at low internisty iterspec with 2-3 sprints of 5 secs are prescripbed force
recovery 2-3 minutes : rest against min force
acceleration 5-10: cycle for 5-10 secomds at 1/3 speed (20-50 rpm) then 1-5 seconds agaisnt 1/2 to 2/3 prescrobec foce at ner max
test 30 sec: cycle at highest rpm
cool down 2-3 mintes at low intensity

39
Q

what results do you get from monark

A

of pedal revs

40
Q

what results do you get from velotron

A

peak
mean
min

power

41
Q

does a person do more work if they run isntead of walk up the stairs?

A

no because work does not take into acount time but they will have a higher power

42
Q

what is the formulat for power

A

power (watts) = work/time

43
Q

what is 1 watt

A

1 j/s
