What is the effect of exercise on urine output?

Question

What are the underlying physiological mechanisms regulating this effect?

Answer 1

Exercise and sweating causes dehydration and increases the osmolality of the blood. Both of these stimuli cause retention of water via anti-diuretic hormone. Additionally, the adrenergic output associated with exercise stimulates the renin-angiotensin axis, which causes aldosterone release, causing the kidneys to retain fluid and salt. Urine output decreases.

Answer 2

For normal people, not much, and the measurement would be like finding a needle in a haystack. The increased cardiac output is not going to result in a corresponding increase in urine output because there are a ton of regulating mechanisms. Also, exercise causes an increased water loss in the breath and in the skin (sweat), along with an increased thirst. Lots of confounding variables.

Answer 3

Intrepyd said it best exactly what the anatomy and physiology books would tell you.

Answer 4

sweating and therefore dehydration, can lead to lesser urine output, and, that, in turn, can result in retention, if prone! but normal exercise, in normal health, and adequate compensation thro' water intake, can safeguard!

Answer 5

if one strains to much it could harm the prostate. as a result of recking one part of this area things may not work well. if you work out try not to over do it.

Answer 6

exertion acts as a diuretic.
