Abstract

The aim of the present study was to evaluate and compare the upper-body aerobic fitness characteristics in 2 groups of competitive surfers with different performance levels. Thirteen male competitive surfers performed an incremental dry-land board paddling test to determine specific peak oxygen uptake (VO2peak), peak power output (Wpeak) and the exercise intensity (%VO2peak) that elicits a blood lactate concentration of 4 mmol x L(-1) (LT4). As a measure of surfing performance, surfers were ranked according to their competitive season performance (RANK) and divided into 2 groups based on their performance level; European top-level competitive surfers (ELS) (n = 7) and regional level competitive surfers (RLS) (n = 6). ELS reached significantly higher values than RLS for Wpeak (154.71 +/- 36.82 W vs. 117.70 +/- 27.14 W: P = 0.04) and LT4 (95.18 +/- 3.42 %VO2peak vs. 88.89 +/- 5.01 %VO2peak; P = 0.02) but not VO2peak (3.34 +/- 0.31 L x min(-1) vs. 3.40 +/- 0.37 L x min(-1); P = 0.77). Spearman-rank order correlation analysis revealed that RANK was inversely correlated with Wpeak (r = -0.65, P = 0.01) and LT4 (r = -0.58, P = 0.03). These findings identify that better surfers have higher upper body aerobic fitness scores.

摘要

本研究的目的是评估和比较两组不同表现水平的竞技冲浪者的上身有氧适能特征。13名男性竞技冲浪者进行了递增式陆地划桨测试，以确定特定的峰值摄氧量（VO2peak）、峰值功率输出（Wpeak）以及引发血乳酸浓度为4 mmol x L(-1)（LT4）的运动强度（%VO2peak）。作为冲浪表现的一项衡量指标，冲浪者根据其赛季表现进行排名（RANK），并根据表现水平分为两组；欧洲顶级竞技冲浪者（ELS）（n = 7）和地区级竞技冲浪者（RLS）（n = 6）。ELS在Wpeak（154.71 +/- 36.82 W对117.70 +/- 27.14 W：P = 0.04）和LT4（95.18 +/- 3.42 %VO2peak对88.89 +/- 5.01 %VO2peak；P = 0.02）方面显著高于RLS，但在VO2peak方面并非如此（3.34 +/- 0.31 L x min(-1)对3.40 +/- 0.37 L x min(-1)；P = 0.77）。Spearman等级相关分析显示，RANK与Wpeak（r = -0.65，P = 0.01）和LT4（r = -0.58，P = 0.03）呈负相关。这些发现表明，水平较高的冲浪者具有更高的上身有氧适能得分。
