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?

24
Q

What is the enzyme used in the Phosphogen System?

A

Creatine Kinase

25
End product of Glycolysis System?
Pyruvate
26
What does pyruvate do at the end of glycolysis?
1 - converted to lactate (anaerobic glycolysis) 2 - taken to mitochondria for Kreb's Cycle (aerobic glycolysis)
27
metabolic acidosis
exercise-induced decrease in pH
28
relationship between exercise intensity and lactate production
directly (increase intensity & increase lactate production)
29
where is lactate processed in the body?
Liver
30
What is the process to convert lactate to glucose?
Cori Cycle
31
How many ATP produced from 1 molecule of glucose?
38 ATP
32
What enzyme breaks down triglycerides?
lipase
33
How long to replenish ATP and CrP after depletion?
ATP = 3-5 min CrP = 8 min
34
How much glycogen is stored in muscles and liver?
muscle = 300-400g liver = 70-100g
35
At what blood glucose level do hypoglycemic reactions tend to begin?
<2.5 mmol/L
36
What is the optimal amount of carbohydrate to replenish post-exercise?
0.7 - 3.0g of carbohydrate/kg
37
% of fat and carbohydrate as fuel during rest?
70% fat 30% carbohydrate
38
Oxygen debt
Anaerobic contributions to initiating exercise, "made up for" during EPOC
39
% of maximum power for Phosphagen System?
90 - 100% power
40
% of maximum power for Fast Glycolysis System?
75 - 90% power
41
% of maximum power for Slow Glycolysis and Oxidative System?
30 - 75% power
42
% of maximum power for Oxidative System?
20 - 30% power
