This study aimed to determine the key performance indicators of inshore sailing during the sailing Tour de France. Technical and physical parameters were investigated to determine the discriminating factors between successful and less successful international level sailors. Measurements from 21 sailors (mean ± SD; age = 23.81 ± 4.18 years) were conducted prior to the sailing Tour de France. Global Positioning System data of all participating teams (n = 23) was analysed. Sailors were divided into two groups (i.e. successful and less successful) according to qualifying performance percentage. The differences between successful and less successful sailors were explored by means of independent t-tests. Results indicate that successful boats displayed higher maximal speed, higher average speed and more efficient starting performance per race than less successful boats. Successful sailors have stronger handgrip strength, higher isometric maximal voluntary force relative to bodyweight (isometric mid-thigh pull) and more powerful submaximal pulling (bench pull) actions than their less successful counterparts. The results of this study suggest that multiple sailing, physical and physiological variables are related to sailing performance in inshore sailing. Therefore, we emphasize the importance of integrating specific testing protocols to evaluate the performance potential of inshore sailors participating in the sailing Tour de France.
本研究旨在确定帆船环法赛中的近岸航行的关键绩效指标。研究调查了技术和物理参数，以确定国际水平的成功和不成功水手之间的区分因素。在帆船环法赛之前，对 21 名水手（平均 ± SD；年龄 = 23.81 ± 4.18 岁）进行了测量。对所有参赛队伍（n = 23）的全球定位系统数据进行了分析。根据资格赛表现百分比，水手们被分为两组（即成功组和不成功组）。通过独立 t 检验探索成功组和不成功组水手之间的差异。结果表明，成功的船只在每场比赛中的最大速度、平均速度更高，起跑性能更高效。成功的水手的握力更强，相对于体重的等长最大自主力量（等长大腿中部拉力）更高，亚最大拉力（卧推）动作更有力。本研究的结果表明，多种航海、身体和生理变量与近岸航海的航海表现相关。因此，我们强调整合特定测试方案以评估参加帆船环法赛的近岸水手的表现潜力的重要性。
