Competitive surfing is a growing sport with evolving performance and safety demands. One particular challenge surfers face is the need to endure long breath-holds following bouts of surf paddling. The purpose of this study was to examine the association between aerobic fitness markers, such as VO and ventilatory thresholds, and post-paddling breath-hold capacity in competitive surfers. Eleven male collegiate level competitive surfers completed both a maximal graded exercise test and a simulated post-paddling breath-hold challenge on a modified paddling ergometer. Associations between markers of aerobic fitness and post-paddling breath-hold capacity were tested using linear regression modeling. The overall regression model indicated a positive linear association between the assessed markers of aerobic fitness and post-paddling breath-hold capacity ( = .828, = 0.686, 0.035). This association was explained by differences in VO ( = 0.975, = .034). These findings suggest that VO may be an important training target for programs aimed at improving breath-hold capacity in surfers.
竞技冲浪是一项不断发展的运动，对运动员的表现和安全要求也在不断提高。冲浪者面临的一个特殊挑战是，在划水冲浪后需要长时间屏气。本研究的目的是探讨有氧适能指标（如VO₂和通气阈值）与竞技冲浪者划水后屏气能力之间的关联。11名大学水平的男性竞技冲浪者在改良的划水测力计上完成了一次最大分级运动测试和一次模拟划水后屏气挑战。使用线性回归模型测试有氧适能指标与划水后屏气能力之间的关联。总体回归模型表明，所评估的有氧适能指标与划水后屏气能力之间存在正线性关联（R² = 0.828，F = 0.686，p = 0.035）。这种关联可以通过VO₂的差异来解释（β = 0.975，p = 0.034）。这些发现表明，VO₂可能是旨在提高冲浪者屏气能力的训练计划的一个重要训练目标。
