Comparison of cognitive auditory event related potentials and executive functions in adolescent athletes and non-athletes - A cross sectional study.
2019
There is strong evidence for the positive physical health outcomes of physical conditioning (athletic training. But there is a dearth of data on the impact of exercise on cognition, particularly in the adolescent age group. Further, most of the studies done on this topic are mainly acute in nature, and few that have seen long term effect of exercise have very rarely used objective measures such as event-related potentials. Hence, the present study was conceived to compare cognition in athletes (individual who have undergone long term physical activity) and non-athletes. We designed a cross-sectional comparative study involving apparently healthy volunteer boys in the age group of 10-19 years-non-athletes (n = 30) and athletes (n = 30). Paper pencil tests such as letter cancellation test, auditory and visual recognition reaction time, trail making test (A and B) were recorded along with auditory event-related potentials (N100, P200, N200, and P300). Data were analyzed using an unpaired t-test and Mann-Whitney U test according to the data distribution. Athletes completed letter cancellation task and trail making test faster than non-athletes. Athletes visual and auditory reaction time were lesser. Athletes had reduced latency and higher amplitude of auditory event-related potentials (N100, P200, N200, and P300) as compared to non-athletes. Hence, we conclude that athletic level physical training has a beneficial role in the executive cognitive domain among adolescents.
