The purpose of the study was to explore effects of core training on selected physiological parameters of university level male medium fast bowlers in cricket. Totally 10 medium fast bowlers were selected through purposive sampling aged 17-27 years. Pre and Post test data were collected and then compared values of all the parameters through pared sample “t” test (SPSS, V-26.0) and (sig level-0.05). The significant improvement observes in Diastolic Blood pressure, Vital Capacity, Body Fat Percentage, Resting Heart Rate (Sig. 2-tailed- .047, .013, .000, .029,.001) and only in the Systolic Blood pressure no significance differences (Sig. 2-tailed-.792) were found but some how mean differences were observed (mean difference- .5000). As a result, it could be said that there are positive effects of core strength training on selected physiological parameters of university level male medium fast bowlers in cricket.
