Endocrine Responses to Resistance Exercise Flashcards
Anabolic Hormones
Insulin-like growth factor, testosterone, and growth hormone (tissue building hormones)
General Adaptation Syndrome
Refers to how the adrenal gland responds to a noxious stimuli; leading to 1) a reduction in function but 2) an increase in resistance to the stressor (referred to as adaptation)
Permissive Hormones
Thyroid hormone; hormones that allow the actions of other hormones to take place
Catabolic hormones
Cortisol and progesterone (protein metabolism/degradation) hormones
Location of polypeptide hormone receptors
In cell membrane
Location of steroid and thyroid hormone receptors
In the cytosol
Where are hormones synthesized, stored, and released from?
Endocrine glands
Intracine/Autocrine Secretion
The hormone acts on the same endocrine cell that released the hormone (does not enter the bloodstream)
Paracrine Secretion
The released hormone acts on the cells adjacent to the cell that released the hormone (does not enter the bloodstream)
Allosteric Binding
When a substance binds to a hormone receptor and either increases or decreases the cellular response to the primary bound hormone
What are the 3 main categories of hormones in the body?
Steroid, polypeptide, and amine hormones
What types(s) of hormones are fat soluble and diffuse across the cell membrane, binding to receptors in the cytosol?
Steroid hormones
What type(s) of hormones are NOT fat soluble and must bind to receptors in the cell membrane which then propagates the signal in the cell through a cascade of signaling events and secondary messengers?
Polypeptide and amine hormones
Primary steroid hormones (androgen) that interacts with skeletal muscle tissue
Testosterone
Which of the exercise hormones has the greatest effect on neural changes?
- Testosterone
- Growth Hormone
- IGF-1
- Cortisol
Testosterone
