Cardiac autonomic balance is altered after exercise. However the impact of the cool-down exercise in this response remains unclear. Our objective is to assess the influence of cool-down exercise on parasympathetic reactivation following exercise. On four occasions, six young(22.4 ±.9 years) healthy males performed, in random order, sub-maximal cycling bouts, each followed by 10 min of recovery period: sitting complete rest, cool-down pedaling with loadless, cool-down pedaling with 30% of work load, and cool-down pedaling with diminishing loads. Electrocardiogram data were collected during 5 min periods in the sitting position, at rest before exercise then at 10 min following cessation of exercise. Parasympathetic reactivation was assessed from heart rate variability(HRV) indices. HRV analysis was performed to obtain time-domain measures [standard deviation of the node to node intervals(SDNN) and root mean square of successive differences(RMSSD)] and frequency-domain measures [normalized LF and HF power and total power(TP)]. Heart rate following cooling-down exercises was significantly lower than the corresponding heart rate without cool-down exercise(p=.05). Analysis of heart rate variability revealed a significant increase in parasympathetic measures after cool-down exercise, as compared to complete rest without cool-down exercise(p=.05), and there was no significant differences among the three cool-down exercises. These results suggest that cool-down exercise may be effective in enhancing cardiac parasympathetic reactivation following endurance exercise.
