Aerials and their influence on World Surfing League surfer performance (WSL flights)

Abstract This research aimed to verify whether the number of airplanes run by surfers in the 2016 Word Surf League (WSL) men's season and their grades were related to their final classification in the events and season. Were viewed 3475 waves from 49 surfers and selected for analysis 275 waves. Spearman's correlation test, one-way ANOVA, and t-test, with p?0.05, were used for statistical analysis. The air proved to be an effective maneuver in isolated clashes, helped to reach the finals and decide events, but did not prove to be the main determinant of the season's final standings. The average of the marks attributed to the reverse 360 ??aerial was significantly higher than the notes attributed to the reverse aerial, however, the variables the position of the surfer in front or back to wave and whether or not to grab the board edge did not present significant differences.

摘要 本研究旨在验证2016年世界冲浪联盟（World Surf League，WSL）男子赛季中，冲浪选手完成的空中动作次数与其所获评分，是否与选手在各赛事及赛季的最终排名存在关联。本次研究共观测49名冲浪选手的3475个浪次，最终选取275个浪次用于分析。统计分析采用斯皮尔曼相关性检验、单因素方差分析（one-way ANOVA）及t检验，显著性水平设定为p≤0.05。研究结果显示，空中动作在一对一对决中为高效动作类型，有助于选手晋级决赛并决定赛事胜负，但并未被证实为影响赛季最终排名的核心因素。针对反身360度空中动作（reverse 360 aerial）所赋予的平均评分，显著高于反身空中动作（reverse aerial）的平均评分；然而，冲浪选手相对于浪的前后位置、是否抓握板边这两个变量，均未表现出显著差异。
