On the other hand, exercise of some intensity will cause less rise of pulse rate after trainingAthletic pseudonephritis ; prolonged, heavy exercise, increases proteins, cells and other abnormal substance in urine due to1. Decrease in renal blood flow (RBE) produces glomerular capillary hypoxia, and increases permeability to large molecules2. Increase in plasma proteins during exercise3.
