Flashcards in Ch. 3 Endocrine Responses to Resistance Exercises Deck (18):
1

hormones

chemical messengers that are synthesized, stored, and released into the blood by endocrine glands and certain other celss

2

endocrine glands

body structures specialized for secretion

3

neuroendocrinology

refers to the study of the interactions between the nervous system and the endocrine system

4

anabolic hormones

hormones that promote tissue building

5

catabolic hormones

attempt to degrade cell proteins to support glucose synthesis

6

lock-and-key theory

where the hormone receptor is the lock and the hormone the key

7

cross-reactivity

where a given receptor partially interacts with hormones that are not specifically designed for it

8

allosteric binding sites

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

9

downregulation

the inability of a hormone to interact with a receptor

10

hormone-receptor complex (H-RC)

formed when the hormone binds with its receptor inside the cell causing a conformation shift in the receptor and activating it

11

polypeptide hormone

made up of amino acids, like growth hormone and insulin

12

secondary messengers (STAT)

bring messages from polypeptide hormones across the cell membrane

13

diurnal variations

normal fluctuations in hormone levels throughout the day

14

what kind of exercises result in acute increased serum total testosterone in men?

Large muscle group excercises

15

What secrets growth hormone?

pituitary gland

16

Growth hormone

with resistance training it enhances amino acid uptake and protein synthesis in skeletal muscle, resulting in hypertrophy of both Type I and II muscle fibers

17

cortisol

the primary signal hormone for carbohydrate metabolism and is related to the glycogen stores in the muscle

18

Catecholamines

secreted by the adrenal medulla and are important for the acute expression of strength and power because the hormones act as central motor stimulators and peripheral vascular dilators and enhance enzyme systems in muscle
