Effect of 3-Piece Golf Ball with Difference Structures on Golf Ball Performance according to Driver and 52 Degree Wedge Shot

다국어 초록 (Multilingual Abstract)

[Purpose] This study aims to demonstrate how, in 3-piece golf balls, the structure difference between dual core with single cover (DSB) and single core with dual cover (SDB) balls can affect the performance of drive shots and 52 degree wedge shots. [Method] The differences between the two ball types were determined by conducting drive shots at 80, 90, and 100 mph swing speeds along with 52-degree wedge shots at 70 mph. [Result] No significant differences were observed between the two balls in the drive shot performance at 80 mph swing speed. In contrast to 80 mph, better performances in DSB were observed in the distance to maximal height (p=0.005), carry distance (p=0.001), and total distance (p=0.027) at 90 mph swing speed. At 90 mph, spin rate (p=0.007), maximal height (p=0.032), carry distance (p=0.006), and flight time (p=0.041) in DSB were observed better performance compare with SDB. Launch angle (p<0.001), back spin rate (p<0.001), total spin rate (p<0.001), height, and decent angle (p<0.001) at wedge test were significantly difference between DSB and SDB. The maximal height (p=0.032), backspin rate(p=0.007), carry distance(p=0.006), and flight time(p=0.041) were also significantly difference between DSB and SDB. [Conclusion] These results demonstrated that DSB would be the more favorable option than SDB for golfers or coaches trying to improve their drive distance and shot preciseness.
