This study aimed to identify the physical and/or anthropometric qualities explanatory of adolescent surf lifesavers participating in paddling activities.
Cross-sectional observational study.
A total of 53 (14-18years) male participants were recruited and classified into two groups; paddlers (n=30; actively participating in paddling), non-paddlers (n=23; not actively participating in paddling). All participants completed a testing battery that consisted of 16 physical (isometric strength and muscular endurance) and anthropometric (height, mass, segment lengths and breadths) assessments. Binary logistic regression models and receiver operating characteristic curves were built to identify the physical and/or anthropometric qualities most explanatory of paddling status (two levels: 1=paddlers, 0=non-paddlers).
Significant between group differences were noted for 14 of the 16 assessments (P<0.05; d=0.59-1.29). However, it was the combination of horizontal shoulder abduction isometric strength, body mass, and sitting height that provided the greatest association with paddling status (Akaike Information Criterion=47.13). This full model successfully detected 87% and 70% of the paddlers and non-paddlers, respectively, with an area under the curve of 84.2%.
These results indicate that there are distinctive physical and anthropometric qualities that may be advantageous for prospective paddling athletes to possess. Practitioners should integrate assessments of horizontal shoulder abduction isometric strength, body mass, and sitting height, as well as their subsequent cut-off thresholds, into talent detection programs focused toward the recognition of performance potential in paddling-oriented sports.
本研究旨在确定能够解释青少年冲浪救生员参与划桨活动的身体和/或人体测量学特征。
横断面观察性研究。
共招募了53名年龄在14至18岁之间的男性参与者，并将其分为两组；划桨者（n = 30；积极参与划桨），非划桨者（n = 23；不积极参与划桨）。所有参与者都完成了一组测试，该测试包括16项身体（等长力量和肌肉耐力）和人体测量学（身高、体重、身体各部分长度和宽度）评估。构建二元逻辑回归模型和受试者工作特征曲线，以确定最能解释划桨状态的身体和/或人体测量学特征（两个级别：1 = 划桨者，0 = 非划桨者）。
16项评估中的14项在组间存在显著差异（P < 0.05；d = 0.59 - 1.29）。然而，水平肩外展等长力量、体重和坐高的组合与划桨状态的关联最大（赤池信息准则 = 47.13）。这个完整模型分别成功检测出87%的划桨者和70%的非划桨者，曲线下面积为84.2%。
这些结果表明，存在独特的身体和人体测量学特征，对于未来的划桨运动员来说，拥有这些特征可能具有优势。从业者应将水平肩外展等长力量、体重和坐高的评估及其后续的临界阈值纳入针对识别划桨类运动表现潜力的人才选拔计划中。
