Aim: This study assessed the dehydration's impact on Cricket bowling performance.  Methodology: To achieve the purpose, eight bowlers were selected from Gandhigram Rural Institute (GRI), Tamil Nadu. Their age ranged between 18 and 22 years. 48 deliveries bowled by the eight male bowlers before and after the controlled 30-over Cricket match organized at 24-27°C conditions.  Body weight, urine specific gravity (USG), ball speed and accuracy was tested prior to and after the treatment. The data were analysed with simple correlation, coefficient of variation and Friedman two way analysis of variance test. Results: The influence of treatment, the bowlers were moderately dehydrated despite hydration efforts. Bowlers’ ball speed and accuracy was decreased by 2.04km/h and 19.27 points respectively. Correlation analyses showed there was some association between ball speed-accuracy. Conclusions: The bowlers accomplished the state of dehydration at the end of 30-over play which remarkably decline the bowling speed and accuracy..
