This study investigated the effects of wave conditions on performance and the physiological responses of surfers. After institutional ethical approval 39 recreational surfers participated in 60 surfing sessions where performance and physiological response were measured using global positioning system (GPS) heart rate monitors. Using GPS, the percentage time spent in surfing activity categories was on average 41.6, 47.0, 8.1, and 3.1% for waiting, paddling, riding, and miscellaneous activities, respectively. Ability level of the surfers, wave size, and wave period are significantly associated with the physiological, ride, and performance parameters during surfing. As the ability level of the surfers increases there is a reduction in the relative exercise intensity (e.g., average heart rate as a percentage of laboratory maximum, rpartial = -0.412, p < 0.01) which is in contrast to increases in performance parameters (e.g., maximum ride speed (0.454, p < 0.01). As the wave size increased there were reductions in physiological demand (e.g., total energy expenditure rpartial = -0.351, p ≤ 0.05) but increases in ride speed and distance measures (e.g., the maximum ride speed, 0.454, p < 0.01). As the wave period increased there were increases in intensity (e.g., average heart rate as a percentage of laboratory maximum, rp = 0.490, p < 0.01) and increases in ride speed and distance measures (e.g., the maximum ride speed, rpartial = 0.371, p < 0.01). This original study is the first to show that wave parameters and surfer ability are significantly associated with the physiological response and performance characteristics of surfing.
本研究调查了波浪条件对冲浪者表现及生理反应的影响。经机构伦理批准后，39名休闲冲浪者参与了60次冲浪活动，使用全球定位系统（GPS）心率监测器测量其表现和生理反应。利用GPS测量发现，冲浪者在等待、划水、冲浪和其他活动中所花费的时间百分比平均分别为41.6%、47.0%、8.1%和3.1%。冲浪者的能力水平、浪高和浪周期与冲浪过程中的生理、冲浪及表现参数显著相关。随着冲浪者能力水平的提高，相对运动强度降低（例如，平均心率占实验室最大心率的百分比，偏相关系数r = -0.412，p < 0.01），这与表现参数的增加形成对比（例如，最大冲浪速度，r = 0.454，p < 0.01）。随着浪高增加，生理需求降低（例如，总能量消耗，偏相关系数r = -0.351，p≤0.05），但冲浪速度和距离测量值增加（例如，最大冲浪速度，r = 0.454，p < 0.01）。随着浪周期增加，强度增加（例如，平均心率占实验室最大心率的百分比，相关系数r = 0.490，p < 0.01），冲浪速度和距离测量值也增加（例如，最大冲浪速度，偏相关系数r = 0.371，p < 0.01）。这项原创研究首次表明，波浪参数和冲浪者能力与冲浪的生理反应及表现特征显著相关。
