Endocrine System Flashcards
Endocrine Glands
Produce and secrete hormones
Have multiple roles
Interact with multiple tissues
Interact with each other
Hormones
Builds tissue
Anabolic
Breaks down tissue
Catabolic
Only specific receptor sites in cells will interact with specific hormones
Lock and key theory
Anabolic hormones
Testosterone
Growth hormones
Men have how much more testosterone than women
15-20 x’s
3 main functions of testosterone
- Directly affects skeletal muscle
- directly affects the motor nerves
- releases growth hormone
5 Guidelines to release more test
- work large muscle groups
- perform compound exercises
- lift heavy weights 85% or more or high volume
- short to moderate rest period 30-90 seconds
- experience level
6 Growth hormone factors
- produced in pituitary gland
- decreases body fat
- decreases glycogen utilization
- increases protein synthesis
- increases cartilage synthesis
- increases immune system
3 catabolic hormones
Cortisol
Catecholamines (adrenaline)
Glycogen
- Released when glycogen stores are low and the body needs high intensity energy
- Released from adrenal glands (located on kidneys)
Cortisol
3 functions of cortisol
- Decrease protein synthesis
- Increase protein breakdown
- Turns amino acids into glucose
Epinephrine / Norepinephrine
Use everything i got now
Catecholamines (adrenaline)
3 functions of catecholamines
- Increase hr
- Increase muscle force
- Increase energy availability
NSCA specifically states that these two supplements have a performance enhancing effect
Creatine
Caffeine
3 types of BCAA supplements
3-Leucine
Iso-Leucine
Valine
Amino acid most linked to recovery
Glutamine
Muscle buffer
Beta-Alanine
Lowers the pH of a muscle during training (decreases hydrogen ions)
Beta-Alanine
