Q

When should an athlete wear a weight belt?

A

maximal and near maximal sets

17
Q

The breakdown of larger molecules into smaller ones

A

catabolism

18
Q

The synthesis of larger molecules from smaller ones

A

Anabolism

19
Q

Exergonic reaction

A

energy releasing and catabolic

20
Q

Endergonic reactions

A

require energy and anabolic

21
Q

Phosphagen system equation

A

ADP + CP ATP + Creatine

Creatine kinase enzyme over arrows

22
Q

How much ATP does the body store?

A

80-100g

  • cannot be completely depleted
  • skeletal muscle [ ] of CP are 4-6x higher than ATP
23
Q

Glycolysis

A

-breakdown of carbohydrate, either glycogen in muscle or glucose in blood to re-synthesize ATP

24
Q

What is the end result of glycolysis and where can it go?

A
  • Pyruvate
  • converted to lactate in sarcoplasm OR
  • shuttled into mitochondria
25
Q

Anaerobic glycolysis

A
  • Pyruvate is converted to lactate via regeneration of NAD+

- limited in duration d/t H+ production

26
Q

Aerobic glycolysis

A
  • Pyruvate shuttled into mitochondria for Krebs cycle,

- ATP resynth is slow but can occur for longer duration

27
Q

Phosphorylation

A
  • process of adding inorganic phosphate (P) to another molecule
  • ADP + P = ATP
28
Q

Lactate threshold

A

exercise intensity at which blood lactate begins an abrupt increase above baseline concentrations
-increased reliance on anaerobics for energy production

29
Q

When does lactate threshold occur?

A
  • 50-60% maximal O2 uptake in untrained

- 70-80% in trained

30
Q

How many ATP produced for breakdown of single triglyceride (fat)

A

-Over 300

31
Q

How many net ATP are produced via oxidative system for one glucose molecule

A

-38

32
Q

Allosteric binding site

A

-substances other than hormones can enhance or reduce the cellular response to the primary hormone

33
Q

Effects of Testosterone

A
  • stimulates IGF-1 secretion
  • protein synthesis
  • growth and metabolism
34
Q

Exercise variables that increase GH, Testosterone, and cortisol levels,

A
  • large m. group exercises
  • heavy resistance
  • high volume
  • short rest intervals
  • long training experience
35
Q

Effects of Growth Hormone

A

decreased: glucose utilization/synthesis
Increased: protein and collagen synthesis, FFA utilization, lipolysis

36
Q

Which hormone has the greatest influence on neural changes?

A

-Testosterone

37
Q

Acute hormonal changes to exercise provide details about?

A
  • amount and type of stress
  • metabolic demands of the exercise
  • need for changes in resting metabolism
