Lower body and core muscular strength are essential for optimal performance in many sports and competitive surfers have similar strength demands when maneuvering a surfboard to achieve competition success. Presently, the use of unstable surfaces is excessively utilized by surf coaches and trainers and to date, research does not support this as an effective training method for long-term improvements. Therefore, the purpose of this study was to determine the effectiveness of an 8-week Core Strength Training Program (CSTP) on a battery of field tests specific to assessing core musculature and lower body strength for junior competitive surf athletes. Nineteen American junior competitive surf athletes (age:15.7±1.01yrs, height:1.77±0.007m, mass:64.67±9.08kg) completed pre- and post-tests with a transitional pre-season to in-season 8-week CSTP intervention. The battery of tests included: rotational power (RP), time to peak acceleration (TP), maximal acceleration (Ma), maximal countermovement jump (CMJ), estimated peak power (PP), core strength (CS), core endurance (CE), and rotational flexibility (RF). Means, standard deviations, RMANOVA with a significance level of p < 0.05, and effect sizes were computed. Results demonstrated significant improvements in L.RP, TP, CMJ, PP, CS, and RF. Based on the results, the CSTP is an effective training program for surf coaches and strength and conditioning professionals to improve strength in the core musculature and lower body. In addition, we conclude implementation of the CSTP enhances athletic performance measurements which will likely increase competition success.
下半身和核心肌肉力量对于许多运动的最佳表现至关重要，竞技冲浪者在操控冲浪板以取得比赛成功时也有类似的力量需求。目前，冲浪教练和训练师过度使用不稳定表面，而迄今为止，研究并不支持这是一种能带来长期改善的有效训练方法。因此，本研究的目的是确定一项为期8周的核心力量训练计划（CSTP）对一系列针对青少年竞技冲浪运动员核心肌肉组织和下半身力量评估的现场测试的有效性。19名美国青少年竞技冲浪运动员（年龄：15.7±1.01岁，身高：1.77±0.007米，体重：64.67±9.08千克）在赛季前过渡到赛季中的8周CSTP干预前后完成了测试。测试项目包括：旋转功率（RP）、达到峰值加速度的时间（TP）、最大加速度（Ma）、最大反向移动跳跃（CMJ）、估计峰值功率（PP）、核心力量（CS）、核心耐力（CE）和旋转灵活性（RF）。计算了平均值、标准差、显著性水平p<0.05的重复测量方差分析以及效应量。结果表明，在L.RP、TP、CMJ、PP、CS和RF方面有显著改善。基于这些结果，CSTP是冲浪教练以及力量和体能训练专业人员提高核心肌肉组织和下半身力量的有效训练计划。此外，我们得出结论，实施CSTP可提高运动表现指标，这可能会增加比赛成功率。
