The intermittent manner of surfing accentuates the importance of both the aerobic and anaerobic energy systems. Currently, the optimal method of assessing surfing-specific aerobic fitness is using a swim bench (SWB) ergometer; however, their limited availability presents a barrier to surfers wanting to know their maximal aerobic power (VO). As a result, the aims of this pilot study were to determine the VO of recreational surfers using a new commercial SWB ergometer and to propose and examine the feasibility of a regression model to predict SWB ergometer VO values. A total of nine recreational surfers were assessed where body measurements were conducted followed by maximal aerobic capacity testing (swim bench and treadmill) to profile the cohort. Findings demonstrated that VO values were significantly greater ( < 0.001) on the treadmill compared to the SWB ergometer ( = 66.01 ± 8.23 vs. 37.41 ± 8.73 mL/kg/min). Peak heart rate was also significantly greater on the treadmill compared to the SWB ergometer. Multiple regression analysis was used to produce a model which predicted SWB VO values with an R² value of 0.863 and an adjusted R² value of 0.726. The physiological profiling of the recreational cohort coupled with a surfer’s predicted SWB VO value will allow for identification of surfing-specific aerobic fitness levels and evidence-based training recommendations.
冲浪的间歇性方式凸显了有氧和无氧能量系统的重要性。目前，评估特定于冲浪的有氧适能的最佳方法是使用游泳长椅（SWB）测力计；然而，其有限可用性给想要了解自身最大有氧功率（VO）的冲浪者带来了障碍。因此，这项初步研究的目的是使用新型商用SWB测力计确定休闲冲浪者的VO，并提出并检验预测SWB测力计VO值的回归模型的可行性。总共对九名休闲冲浪者进行了评估，先进行身体测量，然后进行最大有氧能力测试（游泳长椅和跑步机）以描绘该群体特征。结果表明，与SWB测力计相比，跑步机上的VO值显著更高（<0.001）（分别为66.01±8.23与37.41±8.73毫升/千克/分钟）。跑步机上的最高心率也比SWB测力计显著更高。使用多元回归分析得出一个模型，该模型预测SWB VO值的R²值为0.863，调整后的R²值为0.726。休闲群体的生理特征分析以及冲浪者预测的SWB VO值将有助于确定特定于冲浪的有氧适能水平并提供基于证据的训练建议。
