The golf swing had been investigated mathematically with least mean square error method whether the club head could be swung in a single inclined plane. The recent findings suggest that the club head trajectory did not fit exactly to a single plane but could consider its motion as a plane with minor errors. The purpose of this study was to verify whether a single plane could be fitted to club motion with singular value decomposition method. Six professional golfers were participated and the swing movements with driver were analyzed by three-dimensional analysis techniques. The results can be summarized as follows. The orthogonal distances errors from the fitted plane to the center of the club head were shown between 2.6cm and 7.2cm. By considering Cochran & Stobbs"s assertion that 30 yards driving distance reduction with 1.8m mishit from the sweet spot the average distance error from the fitted swing plane to the club head center was 4.23cm at impact and the error could lead the club head mishit the sweet spot. As a result the club head trajectories were not fitted to a single plane.
