Effect of intervention on heart rate variability measures and baroreflex sensitivity (a) NN—R-R interval (ms); (b) HR—heart rate (bpm—beats per minute); (c) SDNN—standard deviation of NN intervals (ms); (d) RMSSD—square root of the mean of the sum of squares of differences between adjacent NN intervals (ms); (e) TP—total power (ms²); (f) LF—low frequency power (ms²); (g) BRS—baroreflex sensitivity (ms/mm Hg); values expressed as Mean±SEM; *P < 0.05, **P < 0.01, pre versus post, within group comparison; ^† P < 0.05 Group I versus Group II at 2 weeks.
