NUMBER OF PEDAL REVOLUTIONS

Question 6

true or false: muscle fibers have enough ATP to last for a couple minutes of intense muscular work

Answer 7

tthe phosphocreataine system (PCR)

Question 8

how long cvan the adenosite triphosphate PCR system give energy for

Answer 8

allows for 5-10 seconds of intense muscular work

the anerobic glyclotic system

Question 10

when is the anoerboic glyoclity system highly active

Answer 10

between 5-50 seconds

Question 11

how does anaerboic glycolisis allow for ATP production

Answer 11

without oxygen

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

Question 12

what happens when gluocse is used as a fuel in the absense of oxygen

Answer 12

lactate is produced as a by product

Question 13

Answer 13

fatigue

Question 14

how long is recovery

Answer 14

depending on subjectstraining level, 1-2 minites

Question 15

explain the immediate energy system

Answer 15

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

Question 16

explain the short term energy

Answer 16

Short-term energy
• Lactate-Forming System (glycolytic anaerobic; short-term glycolytic)
• Moderate pace, moderate yield (11 enzymes - 11 steps) – 5 to 50
sec

Question 17

explain the long term energy

Answer 17

Aerobic system is slow pace, high yield

Question 18

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

Answer 18

80%

Question 19

what does more prolongued physical activaty require

Answer 19

a more effiecient and slower atp generating sysym

=OXIDATIVE GLYCOLUYSIS

Question 20

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

Answer 20

true

Question 21

what does peak anaerboic closely reflect and why

Answer 21

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

Question 22

what is mean anaerobic an indicator of and why

Answer 22

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)

Question 23

explain atop contribution in first 10 second

Answer 23

70% from immediate (Atp-pcr)

15% from short term system

Question 24

explain atp contribution during 30 seconds

Answer 24

30% from immediate

50% from anerobc glycol (Shory term)

Question 25

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

Answer 25

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

Question 26

what is the equstion for peak and what does it reflect

Answer 26

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)

Question 27

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

Answer 27

Mean-AnP = Power achieved over entire test = Work (total) / time (total) (Nm/s = watts) = Ability to use system B (anerobic glycolytic sysstem

Question 28

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

Answer 28

Fatigue Index = = (Max An-P – Min An-P / Max An-P) x 100 =Reflects ability to maintian power output from anerboribc energy sysstsms

Question 29

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

Answer 29

true

Question 30

what is the formula for total energy expernditure in kcal

Answer 30

total work (nm) x 0.000239

Question 31

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

Answer 31

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

Question 32

what is the 3 reasons men usually score higher than women

Answer 32

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

Question 33

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

Answer 33

1. Training 2. Heredity / genetics 3. Motivation

what time of the day is best

Answer 37

laate afternnoon

Question 38
