Correlation of Audio-Visual Reaction Time with Body Mass Index & Skin Fold Thickness Between Runners and Healthy Controls.

Audio-visual reaction time is essential for activities like driving and very important in sports persons. Reaction time of 31 National level runners was compared with 31 controls. Runners were subdivided into two groups, group A (>2 yrs & < 3 yrs of training) and group B (>3 yrs & < 10 yrs of training). Correlation between Body Mass Index & Skin Fold Thickness with reaction time was also analyzed. Reaction time was significantly less in runners (p<0.05) when compared to controls and also in group B. Correlation analysis has shown negative correlation of BMI with reaction time with statistically significant value for green color in runners. Skin Fold Thickness also showed a negative correlation with reaction time but was not statistically significant. Improvement in reaction time by regular practice will ultimately improve sports person's performance.
