Background: Snooker is a kind of cue sport in which skill plays an important role. To reach a professional level, snooker players must acquire many physical and mental skills. Strengthening the Core muscles, which provide a foundation for a successful limb function in skill sports such as snooker, can be achieved by performing Pilates exercises. Objectives: The purpose of this study was to investigate the effectiveness of Core muscle training on skill and balance for snooker players. Methods: In this study, 30 male snooker players were divided into Pilates (n = 15) and control groups (n = 15) by randomization. The Pilates group performed the mat Pilates exercises three sessions per week consisting of 30 minutes of Pilates training in addition to one hour of routine snooker training per session for six weeks. The control group performed one-hour routine snooker training three sessions per week at the same time period. To assess the players’,skills, the line-up test was used to measure the break sCore, and the foul number test was used to calculate the foul number. Players’,balance was evaluated by the stork balance test. All tests were performed pre and post 6 weeks of exercise for between and within-group comparisons. Results: Line-up and stork test sCores were significantly increased (P < 0. 05) in the Pilates group compared with the control group. However, there was no significant difference in the foul numbers between groups after Six weeks of Pilates exercises. Conclusions: Six weeks of mat Pilates exercises improves the snooker players’,balance ability and break sCores.
