Aim of the study is to determine the association between the sleep quality with cardiorespiratory fitness among adolescent girls. The association between the sleep quality with cardiorespiratory fitness was predicted by using maximal multistage 3m step rest according to the procedure described by the FITNESSGRAM which is a health related physical assessment. Detailed procedure will be explained in patient words and informed consent will be obtained from all participants. According to the test results the sleep quality was associated with cardiorespiratory fitness. Lower CRF indicates poor sleep quality. This study is an observational study done at Saveetha College of physiotherapy with a sample of 20 females between the age of 15-18 years. The test is assessed carefully before and after performed. The sleep quality is assessed by a questionnaire given to individuals. The results from the test conclude that the girls who were classified as fit were likely to report a better sleep quality when compared to the unfit peers. This study concludes that increased sleep quality has greater significance with cardiorespiratory fitness when compared to decreased sleep pattern.
