Purpose : The purpose of this study was to analyze the effect on the alignment with presence, number and handicap of the golf balls and putters during the putting.
Methods : For 43 adult golfers(48.33±10.07 years old and ?0.07±0.74 logMAR) who know their average score on the field for the last 1 year and without strabismus and amblyopia were selected as subjects. The alignment errors were measured at a putting distance of 1.5 m and 3 m during the putting, by using the golf balls with 0, 1, and 3 aiming lines and the putters with 1 and 3 aiming lines.
Results : As a result of analyzing the alignment errors during the putting in accordance with presence, number and handicap of the golf balls and putters aiming lines, there no effects found that the alignment accuracy of the golf balls accordance with the aiming lines and handicap. However, there was a significant difference found that the putters accuracy increased with 3 lines putter than 1 line putter. Moreover, the predicted putting success rate and subjective satisfaction increased in the golf balls and the putters with 3 lines compared to 1 aiming line.
Conclusion : Alignment of the golf balls and putters is part of the entire putting process. The aiming lines of the golf balls and putters have been shown to reduce the alignment errors. However, for a more definite analysis, a follow-up study considering both the kinematic aspect and visual function is necessary.
