| ABSTRACT |
|
Effects of long distance running on cardiovascular function. The purpose of this study is to identify functional characteristics of heart and blood expression of vascular regulators during rest and GXT (grade exercise test) in elite runners. For this purpose, long distance runners (LDG, n=9) and health male college students (CON, n=9) were participated in this study voluntarily. Body compositions were measured by In-Body 4.0(Bio space, Korea), Bruce protocol were used to GXT with treadmill (Quinton Co. USA) and all parameter were measured during rest and GXT. Heart rate was measured by polar and blood pressure was measured by mercury sphygmomanometer. The results are as follows; RPP were significantly lower in LDG compared to CON whereas PP and MAP were no significantly. Blood expression of NOS after 1 hour recovery were increased in LDG compared to CON. These results were suggested that i) because of the effects of selected factors to heart function were various by capacity of exercise, participating events and environments, if we select some method to test athletes, previously recommending methods to identify clinical condition of cardiovascular system (CVS) for non-athletes should be assortatively chosen, ii) we should to recognize differences of CVS between athletes and non-athletes, and specific protocol is needed to health ageing of athletes |
