Material and Method: A total of 300 participants, which includes 150 male and 150 female participants of age group 18–25 years were recruited

for this study from Maharishi Markandeshwar Institute of Medical Sciences and Research, Mullana [Ambala]. The participants were examined

thoroughly so as to exclude those with the history of any acute or chronic illness or on long term medication or with a history of Traumatic injuries.

Sleep patterns were determined using PSQI scale. A standardized and validated questionnaire in a form of proforma was given to each participant.

BMI was calculated by using Quetelet index and Cardirespiratory fitness was evaluated by using VO2max. VO2max was estimated indirectly by

following the protocol of Queen’s College Step Test [QCT] method.

Result: The result suggests highly positive significant association and correlation between Sleep patterns (PSQI) and BMI and highly negative

significant correlation between BMI and VO2max in both male and female participants.
