Appropriate and valid testing protocols for evaluating the physical performances of surfing athletes are not well refined. The purpose of this project was to develop, refine, and evaluate a testing protocol for use with elite surfers, including measures of anthropometry, strength and power, and endurance.
After pilot testing and consultation with athletes, coaches, and sport scientists, a specific suite of tests was developed. Forty-four competitive junior surfers (16.2 ± 1.3 y, 166.3 ± 7.3 cm, 57.9 ± 8.5 kg) participated in this study involving a within-day repeated-measures analysis, using an elite junior group of 22 international competitors (EJG), to establish reliability of the measures. To reflect validity of the testing measures, a comparison of performance results was then undertaken between the EJG and an age-matched competitive junior group of 22 nationally competitive surfers (CJG).
Percent typical error of measurement (%TEM) for primary variables gained from the assessments ranged from 1.1% to 3.0%, with intraclass correlation coefficients ranging from .96 to .99. One-way analysis of variance revealed that the EJG had lower skinfolds (P = .005, d = 0.9) than the CJG, despite no difference in stature (P = .102) or body mass (P = .827). The EJG were faster in 15-m sprint-paddle velocity (P < .001, d = 1.3) and had higher lower-body isometric peak force (P = .04, d = 0.7) and superior endurance-paddling velocity (P = .008, d = 0.9).
The relatively low %TEM of these tests in this population allows for high sensitivity to detect change. The results of this study suggest that competitively superior junior surfers are leaner and possess superior strength, paddling power, and paddling endurance.
评估冲浪运动员身体表现的适当和有效的测试方案尚未得到很好的完善。本项目的目的是开发、完善和评估一项适用于精英冲浪者的测试方案，包括人体测量学、力量和耐力的测量。
经过初步测试和与运动员、教练和运动科学家的协商，制定了一套特定的测试。44 名有竞争力的青少年冲浪者（16.2 ± 1.3 岁，166.3 ± 7.3 厘米，57.9 ± 8.5 公斤）参加了这项研究，采用了一项精英青少年组（EJG）的日内重复测量分析，以确定测量的可靠性。为了反映测试措施的有效性，然后在 EJG 和 22 名有竞争力的全国青少年冲浪者的年龄匹配的竞争青少年组（CJG）之间进行了性能结果的比较。
从评估中获得的主要变量的测量典型误差百分比（%TEM）范围为 1.1%至 3.0%，组内相关系数范围为.96 至.99。单向方差分析显示，EJG 的皮褶厚度较低（P =.005，d = 0.9），而 CJG 的身高（P =.102）或体重（P =.827）没有差异。EJG 在 15 米冲刺划桨速度方面更快（P <.001，d = 1.3），下肢等长峰值力量更高（P =.04，d = 0.7），耐力划桨速度更快（P =.008，d = 0.9）。
这些测试在该人群中的相对低的%TEM 允许高灵敏度来检测变化。本研究的结果表明，竞技水平较高的青少年冲浪者更瘦，具有更好的力量、划桨力量和划桨耐力。
