ADJUSTMENT OF BLOOD PRESSURE DURING EXERCISE STRESS TEST IN ELITE RUNNERS FROM MANIPUR, INDIA

Abstract


Objectives: Adjustment is a short term response in the body that is associated with exercise. The objective of the study was to observe the adjustment in blood pressure during rest, exercise and recovery in Manipuri elite long distance runners. Design: Observational study. Methods: 12 Manipuri elite long distance runners underwent a 12 minutes treadmill stress test following the standard Bruce protocol. Blood pressure monitoring was done at resting (supine, standing, and hyperventilation), during exercise, and recovery stages during treadmill test by mercury sphygmomanometer with auditory confirmation. Descriptive analysis was used to interpret the data and Mann-Whitney U test to compare the mean. Results: In male runners, the mean resting blood pressure (BP rest) was SBP/DBP (±SD); 118/70 (±7/6) mmHg and rose up-to maximum blood pressure (BP max) of SBP/DBP (±SD); 163/90 (±8/0.0) mmHg whereas, in the female runners, mean resting blood pressure was SBP/DBP (±SD); 110/70 (±6/6) mmHg rose up-to maximal blood pressure of 148/86 (±9/5) mmHg. In male runners, DBP increases slightly during exercise and becomes plateau at steady stage at 6 minutes of exercise. The mean recovery blood pressure (BP rec.) value at 3 minutes in male runners indicated higher chances of future hypertension. Rate of perceived exertion of the runners’ measure through Borg CR10 scale rating ranges from 3-5. Conclusions: SBP and DBP value did not change at resting phase i.e. supine, standing, and hyperventilation position. However, SBP increases rapidly with the onset of exercise and the increase in the DBP is slow and steady yet reaches the plateau faster than the SBP. Regular blood pressure monitoring is recommended for athletes to diagnose hypertension and prevent from sudden cardiac arrest during physical training and competition.
