Vinupradha. P, Roseline Jesintha. V

Abstract :

Back ground : Reaction Time  measurement  constitutes  a  simple,  non– invasive  tool  for  assessing  peripheral  and  central  neural  structures,  thereby  gaining  physiological  importance. Auditory  Reaction  Time  is  defined  as  the  time  interval  from  the execution  of  an  auditory stimulus  to  the  occurrence  of  suitable  appropriate  voluntary  response  as  swiftly as possible.It is a measure of sensorimotor  association. It  calculates  the  alertness  of  a  person –  how  rapidly  a  person  reacts  to  a  stimulus. The  aim  is  to study  the  effect  of  Body  Mass  Index  on  Auditory  Reaction  Time  in adults. Materials&  Methodology: A  sample  of  200 subjects  were  selected  by  purposive  sampling  method  for  the  study. The  study  subjects included  were  those  in  the  age  group  of  21– 40  years  of  which  67  were  with   normal  BMI, 67  were  overweight  and  66 were  obese  based  on  WHO  classification. Auditory reaction time was recorded using Direct RT software.Conclusion:In  our   study  a  significant  difference  is  observed   in  ART   between  normal  Body  Mass  Index, overweight  and  obese  subjects. This  could  be  due  to  the  regions  of  the  ain   involved  in  cognition,  reasoning,  memory,  processing  speed, sensorimotor  performance  and   attention  are  influenced  by  BMI  and  also  abnormal  levels  of  adipokines  result  indisrupted   myelination.
