Background: Cognitive Evoked Potential components are depend on mental attention of subject which are related with cognition, memory. Aims and Objectives: The purpose of study is comparison of properties of event related potential in athletes and cricket players. Material and Methods: Total 60 athletes (15-25 years), from district sports academy, who are regularly practicing from more than 3 years having physical activity 5-7 hrs per week. We have taken 60 healthy age match volunteer controls having physical activity less than 5 hrs per week. Both control & athletes don’t have any abnormality of auditory, neurological problem. Evoked potential, P300 response was recorded using standard auditory oddball paradigm by Rmsemg Ep II machine. All participants received 3-minute conventional, eyes-closed, awake, rehearsal by placing headphone over ears after 5-minute habituation to experimental environment. 2 tones were used as stimulus, frequent low pitch tone & rare high pitch tone. Subjects were instructed to ignore common low pitch tones and raise finger of dominant hand each time when rare high pitch tone occurred. P300 response was recorded from vertex (Cz) in response to stimuli. The mean value of latency, amplitude was further analyzed using anovatest to establish whether statistical differences existed between controls and athletes for ERP. Results: ERP (P300) latency was significantly less and amplitude was significantly more in athletes in athletes as compared to controls having p value >0.001 (highly significant).
