Table 1 Summary of the results of Effect Size (ES) analyses for selected angular kinematic data at the end of the backswing and at ball release. Data were summarized so that only comparisons that recorded Large or Very Large (Hopkins 2002) ES are listed, with those that recorded Trivial, Small or Medium ES left blank.
