[Table/Fig-4]:

The figure depicts pre and post exercise QTc intervals in male and female subjects. The dark grey bar denotes pre exercise data and the light grey bar denotes the post exercise data. The mean pre and post exercise QTc values in males and females are written in the lower panel of the figure. The females had longer QTc duration as compared to males both before and after exercise. The male subjects exhibited a post exercise shortening of QTc interval. The observed gender differences did not attain statistical significance
