Exercise proteinuria is a type of transient proteinuria that usually does not require any treatment, explains DaVita HealthCare Partners. Other causes of transient proteinuria include high fever, stress and cold exposure.

Doctors do not know the exact cause of exercise proteinuria, but they think it is linked to changes in the renin-angiotensin system and prostaglandins caused by strenuous exercise, notes The Journal of Family Practice. Exercise also changes serum proteins and the permeability of the glomerular, which could cause the excess protein in the urine.

To diagnosis proteinuria, doctors collect a urine sample to conduct a dipstick test to search for high levels of protein in the urine, states UpToDate. Urinalysis also looks for any signs of an underlying kidney problem that could cause proteinuria. To determine if the proteinuria is transient, doctors require at least two urine samples given at different times. If both urine samples are positive, the doctor orders additional tests to look for causes of persistent proteinuria and may require a 24-hour urine study.
