    The purpose of this study was to determine the effects of a 36 session COREPOWER machine training intervention and those of a 36 session home-based core training intervention programme on golfers' physical fitness and sport specific performance. It was hypothesised that both modalities will improve on golf related fitness aspects. Subjects comprised of experienced golfers and were randomly divided into a machine group (M: n = 51) and a home group (H: n = 50). The following variables were measured both pre- and post-intervention: lower back flexibility (sit & reach), muscle endurance (sit-ups and push-ups), muscle strength (wall-squats and back dynamometer), cardio-respiratory fitness (3 minute step-test), balance (Biodex Balance System), club head speed and carry distance (Flightscope). The Wilcoxon and Mann-Whitney signed-rank test was used to compare pre and post-intervention measurements within each group with significance set at p < 0.05. An ANCOVA analyses was also run as well as Pearson Product Moment correlations. Results portrayed that with the exception of cardiorespiratory fitness, all variables in both groups showed significant (p<0.05) improvement post intervention. Push-ups (p = 0.000; ↑17.03%; d = 0.92) and driver carry distance (p = 0.000; ↑30.30%; d = 0.40) showed the greatest percentage improvement post intervention within group M, while sit-ups (p = 0.000; ↑14.41%; d = 0.77) and push-ups (p = 0.000; ↑12.52%; d = 0.90) showed the greatest percentage improvement within group H. Lower back strength holds significant correlation to golf performance. Thus both modalities, the COREPOWER machine training and the home-based manual core training were equally effective in improving selected fitness components; however the machine was more effective in improving golf performance parameters. These observations can be applied to golfers in addition to their usual golfing activities as well as to other sport populations as this study formed an evidence base for core training.
