What hormone stimulates sodium and water retention in the kidneys?

Aldosterone

What hormone inhibits gluconeogenesis and decreases with exercise?

Insulin

Which hormone increases from exercise and pulls more glucose from the blood?

Glucagon

What hormone is released from overtraining and insufficient rest?

Cortisol

Which hormone is involved in metabolic rate, with less release leading to a slower metabolic rate?

Thyroid hormone

What hormone is important for lean mass gain and fat metabolism?

Growth hormone

Which hormone stimulates breakdown of fats in adipocytes?

Interleukin 6 (IL-6)

What decreases during heavy intensity exercise, leading to less secretion sites?

Leptin

Which hormone increases sensitivity to insulin and decreases with training?

Leptin

What decreases hormone response (IGF, GH) and is not as noticeable during resistance training?

Leptin
