Effect of Sports on Blood Pressure and Heart Rate Variability: An Interventional Study

Abstract Lack of sufficient physical activity is the second most important contributor to preventable deaths trailing only to tobacco use. So an interventional study was conducted on University students to study effect of sports with Blood Pressure & HRV. Comparison was made between Non exercise control group (n=31) and exercise group (n=31). Exercise group had an intervention of atleast 60 minutes of various sports of moderate to vigorous intensity daily for one year. Various variables of Blood Pressure & HRV were assessed in both the groups and compared by student unpaired ‘t’ test. It was observed in this study that Exercise group had significantly lowered SBP, DBP, MABP. Although there was no significant difference in both the group in frequency domain of HRV but in time domain RR Intervel was significantly lowered in exercise group thanthe other group. So it can be concluded that one hour of Sports intervention significantly decreased Resting Systolic, Diastolic and Mean Arterial Blood Pressure and significantly decreased Resting Heart Rate this indicates a good interplay or modulation between parasympathetic and sympathetic nervous system. So these sports activities should be motivated in college students by including in their daily curricular activities.

Key words: Blood Pressure, Heart Rate Variability, Exercise, Sports
