Objective of the study: The purpose of the study was to compare stress level, basketball performance and menstrual distress in during and post menstrual phases among the university level female basketball players. The relationship between stress level, basketball performance and menstrual distress was also ascertained. Method: A total 80 girls were purposively selected as subjects from different colleges of Punjabi University, Patiala. All the subjects were assessed for stress, basketball performance and menstrual distress in during and post menstruation phases of menstrual cycle. The stress level of subjects was measured with the help of Perceived Stress Scale (PSS) developed by Sheldon Cohen (1988). Menstrual distress was assessed by using the Menstrual Distress Questionnaire (MDQ) developed by Rudolf. H. Moos (1969).Basketball performance was assessed with the help of Johnson Basketball Test Battery design by L. William Johnson (1934). Results: Paired sample t-test revealed that the basketball players had significantly (p<0.05) higher mean value on perceived stress scale in during menstruation phase as compared to post menstruation phase. Menstrual distress, pain and concentration were found to have significantly higher mean values (p<0.05) in during menstruation phase among basketball players. Behaviour and arousal were significantly (p<0.05) associated with perceived stress and control significantly associated (p<0.05) with basketball performancein post menstrual phase. Conclusion: The performance of basketball players was not affected during the menstrual phase. Behaviour and arousal showed significantassociation with stress level and control was observed to be significantly associated with basketball performance in the post menstrual phase
