18
Q

Onset of Blood Lactate Accumulation

A

Blood concentration reaches 4 mmol

19
Q

EPOC

A

Exercise Post-Exercise Oxygen Consumption

When exercising at a rate that exceeds ability to oxidize, so you “pay back” oxygen debt after the workout

20
Q

Exergonic

A

Energy Releasing (usually catabolic)

21
Q

Endergonic

A

Requires Releasing (usually anabolic)

22
Q

Hydrolysis

A

Breakdown of ATP to yield energy

23
Q

How many grams of ATP is stored in the skeletal muscle at rest as Creatine Phosphate?

A

80-100g

24
Q

What is the enzyme used in the Phosphogen System?

A

Creatine Kinase

25
Q

End product of Glycolysis System?

A

Pyruvate

26
Q

What does pyruvate do at the end of glycolysis?

A

1 - converted to lactate (anaerobic glycolysis)
2 - taken to mitochondria for Kreb’s Cycle (aerobic glycolysis)

27
Q

metabolic acidosis

A

exercise-induced decrease in pH

28
Q

relationship between exercise intensity and lactate production

A

directly
(increase intensity & increase lactate production)

29
Q

where is lactate processed in the body?

A

Liver

30
Q

What is the process to convert lactate to glucose?

A

Cori Cycle

31
Q

How many ATP produced from 1 molecule of glucose?

A

38 ATP

32
Q

What enzyme breaks down triglycerides?

A

lipase

33
Q

How long to replenish ATP and CrP after depletion?

A

ATP = 3-5 min
CrP = 8 min

34
Q

How much glycogen is stored in muscles and liver?

A

muscle = 300-400g
liver = 70-100g

35
Q

At what blood glucose level do hypoglycemic reactions tend to begin?

A

<2.5 mmol/L

36
Q

What is the optimal amount of carbohydrate to replenish post-exercise?

A

0.7 - 3.0g of carbohydrate/kg

37
Q

% of fat and carbohydrate as fuel during rest?

A

70% fat
30% carbohydrate

38
Q

Oxygen debt

A

Anaerobic contributions to initiating exercise, “made up for” during EPOC

39
Q

% of maximum power for Phosphagen System?

A

90 - 100% power

40
Q

% of maximum power for Fast Glycolysis System?

A
