摘要
Purpose: This study aimed to quantify the effect of an 8-wk isolated core training program on selected ball and club parameters during the golf swing and also the variability of these measures. Methods: Thirty-six club-level golfers were randomly assigned to an exercise (n = 18) or control (n = 18) group. The exercise group participated in an 8-wk core training program, which included eight basic exercises. Both groups continued with their normal activity levels including golf. Baseline and postintervention measurements included club-head speed, backspin, sidespin, and timed core endurance. Results: Baseline measures for club-head speed, backspin, sidespin, and core endurance test were 79.9 +/- 8.4 mph, 3930 +/- 780 rpm, 1410 +/- 610 rpm, and 91 +/- 56 s for the intervention group and 77.6 +/- 8.8 mph, 3740 +/- 910 rpm, 1290 +/- 730 rpm, and 69 +/- 55 s for the control group (mean +/- SD). The effect of our core training, when compared with control, was a likely small improvement in club-head speed (3.6%; 90% confidence limits = +/- 2.7%) and a very likely small improvement in muscular endurance (61%; +/- 33%). The effect on backspin (5%; +/- 10%) and sidespin (-6%; +/- 20%) was unclear. Baseline variability for club-head speed, backspin, and sidespin (based on 10 swings per golfer) was 5.7% +/- 5.3%, 43% +/- 19%, and 140% +/- 180% for the intervention group and 6.5% +/- 5.3%, 53% +/- 53%, and 170% +/- 130% for control group. The effect of the intervention on within-subject variability was a moderate decrease for club-head speed, a small decrease for backspin, and a small increase for sidespin when compared with control. Conclusion: The benefits achieved from our isolated core training program are comparable with those from other studies.
