31
Q

The study of connection between the neural, endocrine, and immune systems is called _____________________.

A

Neuroendocrine immunology

32
Q

___________ - hormones that proton tissue building

A

Anabolic hormone

33
Q

One of the basic principles in endocrinology is that a given hormone interacts with a specific receptor. This principle is generally referred to as the ______________ (in which the receptor is lock and the hormone is the key)

A

Low-and - key THeory

34
Q

_____________ - a given receptor partially interacts with other hormones.

A

Cross-reactivity

35
Q

Receptors can have _______________ at which substances other than hormones can enhance or reduce the cellular response to the primary hormone.

A

Allosteric Binding Site

36
Q

The inability of a hormone to interact with a receptor is Called _______________ of receptor function

A

Downregulation

37
Q

It has been shown for the hormone ____________ that exercise training affects only the maximal number of receptors, not the binding sensitivity of the receptors.

A

Testosterone

38
Q

After discussing across the sarcolemma, the hormone binds with its receptor to for a ________________, causing a conformational shift in the receptor and thus activating it.

A

Hormone - Receptor Complex (H-RC)

39
Q

_______________ - are made up of chains amino acids; examples are growth hormone and insulin.
- are not fat soluble and thus cannot cross the cell membrane.

A

Polypeptide Hormones

40
Q

_________________ is the primary androgen that interacts with skeletal muscle tissue; I’d hydro testosterone is the primary androgen that interacts with sex-linked tissues.
- It can promote growth hormone release from the pituitary, which can influence protein synthesis in muscle; and in turn growth hormone appears to have a permissive or synergistic effect on testosterones promotion of protein synthesis.

A

Testosterone

41
Q

______________________________ can cause a dramatic catabolic tissue response, and increase in testosterone may be related to the need for protein synthesis to keep up with protein loss.

A

High-intensity aerobic endurance

42
Q
  • Large muscle group exercise
  • heavy resistance (85-95% of 1rm)
  • Moderate to high volume of exercise, achieved with multiple sets, multiple exercises, or both
  • Short rest intervals (30sec to 1min)
  • Two years or more of resistance training experience

These all are variables that can do what to testosterone?

A

Can increase serum testosterone concentrations in boy and younger men

43
Q

________________ - normal fluctuation in hormone levels throughout the day.

A

Diurnal Variations

44
Q

______________ - using an adequate volume of total work result in acute increased total testosterone concentrations in men

A

Large muscle group exercises

45
Q

__________________ - accounts for only 0.5 to 2% of total testosterone; thus higher total testosterone concentration allow for more.
- Heavy resistance exercise 9e.g. Sic sets of 10 reps of 80% of 1RM) can acutely increase ____________ in men and women, although the increase is much smaller for women.

A

Free testosterone

46
Q

Women have about ______ to____ fold lower concentrations of circulating testosterone than men do.

A

15 to 20 fold

47
Q

____________________ concentrations increase in response to breath holding and hyperventilation alone, as well as to hypoxia.

A

Growth Hormone

48
Q

Throughtout the men steal cycle, women have a higher blood concentrations of the __________ than men to greater frequency and amplitude of secretion.

A

22 kDa GH

49
Q

The typical trends for training-related changes in GH appear to be a reduction -______________ response to an absolute exercise stress and alteration in ___________ pulsatilla you characteristics.

A

22 kDa GH

50
Q

Some of the effects of 22 kDa GH are mediated through small polypeptides called _________________.

  • is a 70 amino acid polypeptide
  • this is secret by the liver after 22 kDa GH stimulates liver cells to synthesize it.
