|
Insulin |
1. Regulate glucose entry into all tissue expect the brain 2. Triggers enzymes that perform protein synthesis Exerts a hypoglycemic effect |
|
|
Protein synthesis |
"Making protein" 1. Increase aa transport 2. Increase cellar RNA levels 3. Increases protein formation by ribosomes |
|
|
Diabetes mellitus |
Type 1: develops early in life due to insulin deficiency Type 2: develops later in life and causes insulin resistance, due to obesity, diet and sedentary life |
|
|
Gluconeogenesis |
Secretes by alpha cells in islets of Langerhans Stimulate - glycogenolysis - gluconeogenesis |
|
|
Efficiency of hormones are increase by exercise. How? |
improve target tissue sensitivity AND responsiveness Therefore trained individuals can have a higher hormonal response compared to sedentary individuals |
|
|
Vasopressin aka |
ADH |
|
|
What happens to vasopressin (ADH) with exercise |
Slightly reduced at a given workload |
|
|
What happens to cortisol Durning exercise? |
Slight elevation |
|
|
What happens to insulin with regular exercise |
Increase sensitivity to insulin - generally decreases durning exercise but that affect decreases with training (smaller amount of insulin will have the same affect as larger amount in untrained) - |
|
|
What happens to reproduction hormones with exercise? |
They gradually decrease over time. |
|
|
Two key hormones that the anterior pituitary release |
ACTH Thyrotropin (causes release of thyroid) |
|
|
What affect does ACTH have on the adrenal cortex |
Causes adrenal cortex to release 1. Cortisol 2. Aldosterone |
|
|
Prolonged exercise favours what hormone |
1. Corticotropin releasing hormone |
|
|
What effects does the medulla prolong and augment by secreting E and NE |
Sympathetic |
|
|
What Is more.importsnt Durning exercise, lipolysis or glycolysis? And why |
Lipolysis becuase more energy is stored in fat |
|
|
What is the main function of cortisol |
Promotes triglycerol breakdown to glycerol and fatty acids in adipose tissue |
|
|
What are examples of catecholamines |
E and NE |
