The Effect of Core-Coiling Training for 12 Weeks on Skill-Related Physical Fitness and Performance in Collegiate Baseball Pitchers

OBJECTIVES This study analyzed the effects of core-coiling training for 12 weeks on the pitch velocity and control, which are key factors in skill-related fitness and performance of college baseball pitchers.METHODS The study involved 29 college baseball pitchers from D University in B City, who were di-vided into Core-Coiling Training group (CCTG, n=15) and Resistance Weight Training group (RWTG, n=14). The CCTG underwent core-coiling training for 50 minutes, four times per week, over a period of 12 weeks, while the RWTG maintained regular team training. Baseball related physical fitness and pitching skills were measured before and after the intervention.RESULTS The Resistance weight training group (RWTG) showed significant improvements in func-tional fitness, specifically in Grip strength. The core-coiling training group (CCTG) showed significant improvements in functional fitness, specifically in explosive power and agility. Furthermore, the CCTG demonstrated significant increases in both maximum ball speed and average ball speed post-intervention. In terms of intergroup comparison, the CCTG showed significantly greater gains in agility, maximum ball speed, and average ball speed compared to the resistance weight training group.CONCLUSIONS Based on these results, core-coiling training was found to be an effective intervention that positively impacts the functional fitness and pitching skills of college baseball pitchers. This suggests that Core-Coiling training can be proposed as a new, evidence-based train-ing methodology.
