Abstract

Background & Objectives: The objective of this study was to evaluate the relationship between Blood Serum Potassium and the HRDP in athlete Male Students in University of Mohaghegh Ardabili. Methods: 10 active volunteer men (Mean±SD age= 20±1.21 yrs) was selected as subjects. Hofmann protocol was used to cause the HRDP, one week later and after determining the HRDP by using the S.Dmax method, subjects performed Hofmann protocol again and blood samples were taken from left forearm vein in five phases, simultaneously. The amount of potassium was measured directly by the Flamephotometer. Results: The results show that in all of the subjects(%100), the HRDP and KTP were occurred in average in %78HRmax and %79HRmax, respectively, and the slop of the HR- Time regression line above the HRDP correlated inversely with the Serum potassium - Time regression line above the HRDP (r = - 0.84 & p = 0.01). Conclusions: Based on these results, exercise induced increase in serum potassium during Hofmann incremental cycle ergometer testing protocol, may have a role in the occurrence of the HRDP.
