To determine whether a previously validated performance-testing protocol for competitive surfers is able to differentiate between Australian elite junior surfers selected (S) to the national team and those not selected (NS).
Thirty-two elite male competitive junior surfers were divided into 2 groups (S=16, NS=16). Their age, height, body mass, sum of 7 skinfolds, and lean-body-mass ratio (mean±SD) were 16.17±1.26 y, 173.40±5.30 cm, 62.35±7.40 kg, 41.74±10.82 mm, 1.54±0.35 for the S athletes and 16.13±1.02 y, 170.56±6.6 cm, 61.46±10.10 kg, 49.25±13.04 mm, 1.31±0.30 for the NS athletes. Power (countermovement jump [CMJ]), strength (isometric midthigh pull), 15-m sprint paddling, and 400-m endurance paddling were measured.
There were significant (P≤.05) differences between the S and NS athletes for relative vertical-jump peak force (P=.01, d=0.9); CMJ height (P=.01, d=0.9); time to 5-, 10-, and 15-m sprint paddle; sprint paddle peak velocity (P=.03, d=0.8; PV); time to 400 m (P=.04, d=0.7); and endurance paddling velocity (P=.05, d=0.7).
All performance variables, particularly CMJ height; time to 5-, 10-, and 15-m sprint paddle; sprint paddle PV; time to 400 m; and endurance paddling velocity, can effectively discriminate between S and NS competitive surfers, and this may be important for athlete profiling and training-program design.
确定一种先前经验证的针对竞技冲浪者的性能测试方案能否区分入选(S)国家队的澳大利亚精英青少年冲浪者和未入选(NS)的冲浪者。
32名精英男性竞技青少年冲浪者被分为两组(S组 = 16人,NS组 = 16人)。S组运动员的年龄、身高、体重、7处皮褶厚度之和以及瘦体重比(均值±标准差)分别为16.17±1.26岁、173.40±5.30厘米、62.35±7.40千克、41.74±10.82毫米、1.54±0.35;NS组运动员的相应数据分别为16.13±1.02岁、170.56±6.6厘米、61.46±10.10千克、49.25±13.04毫米、1.31±0.30。测量了力量(反向纵跳[CMJ])、力量(等长股中肌拉力)、15米冲刺划水、400米耐力划水。
S组和NS组运动员在相对垂直跳跃峰值力(P = 0.01,d = 0.9)、CMJ高度(P = 0.01,d = 0.9)、5米、10米和15米冲刺划水时间、冲刺划水峰值速度(P = 0.03,d = 0.8;PV)、400米用时(P = 0.04,d = 0.7)以及耐力划水速度(P = 0.05,d = 0.7)方面存在显著(P≤0.05)差异。
所有性能变量,特别是CMJ高度、5米、10米和15米冲刺划水时间、冲刺划水PV、400米用时以及耐力划水速度,能够有效区分入选和未入选的竞技冲浪者,这对于运动员剖析和训练计划设计可能具有重要意义。
