There has been an increasing interest among CrossFit® coaches and practitioners in identifying indicators of sport performance. This study aimed to examine the correlation between anthropometric measures, cardiorespiratory capacity, power, local muscle endurance, and total athleticism score, with performance in the CrossFit® Open 2021. Fourteen male volunteers (aged 30.3 ± 5.8 years) participated in the study and underwent a series of tests on separate weeks. These tests included assessments of body fat percentage (subcutaneous adipose thickness measured at seven sites), maximal oxygen consumption (2 km test in rowing ergometer), muscle power (one repetition maximum in power clean), and muscle endurance (Tibana test, which included the conclusion of four distinct rounds of work). These results were used to calculate the total score of athleticism, which was then compared to the participants performance during the CrossFit® Open 2021. The athletes presented an average of body fat (8.6 ± 2.0%), maximal oxygen consumption (53.3 ± 2.4 mL. (kg.min)-1), 2km row time (07:00 ± 00:21 mm:ss), 1-Repetition maximum in power clean (125.2 ± 21.2 kg) and Tibana test performance (281.0 ± 35.9 repetitions). Interestingly, the top five athletes with the highest scores also achieved the highest z-scores in the CrossFit® Open 2021. Conversely, the four athletes with the lowest TSA score had the lowest z-scores in the CrossFit® Open. Moreover, almost perfect correlation (r = 0.91; p<0.01) was found between the total athleticism score and z-scores in the CrossFit® Open 2021. The total score may be a single measure and holistic indication of athleticism level in CrossFit®. Furthermore, coaches can potentially apply this useful tool for monitoring athletic performance and designing training sessions that address specific areas of CrossFit® performance.
CrossFit®教练和从业者对确定运动表现指标的兴趣与日俱增。本研究旨在探讨人体测量指标、心肺功能、力量、局部肌肉耐力和总运动能力得分与2021年CrossFit®公开赛成绩之间的相关性。十四名男性志愿者（年龄30.3±5.8岁）参与了该研究，并在不同的周接受了一系列测试。这些测试包括体脂百分比评估（在七个部位测量皮下脂肪厚度）、最大摄氧量（在划船测力计上进行2公里测试）、肌肉力量（力量翻的一次重复最大值）和肌肉耐力（蒂巴纳测试，包括完成四轮不同的工作）。这些结果用于计算运动能力总分，然后将其与参与者在2021年CrossFit®公开赛期间的表现进行比较。运动员的平均体脂率为（8.6±2.0%），最大摄氧量为（53.3±2.4 mL·(kg·min)-1），2公里划船时间为（07:00±00:21分:秒），力量翻的一次重复最大值为（125.2±21.2 kg），蒂巴纳测试成绩为（281.0±35.9次重复）。有趣的是，得分最高的前五名运动员在2021年CrossFit®公开赛中也获得了最高的z分数。相反，总运动能力得分最低的四名运动员在CrossFit®公开赛中的z分数最低。此外，在2021年CrossFit®公开赛中，总运动能力得分与z分数之间发现了几乎完美的相关性（r = 0.91；p<0.01）。总分可能是CrossFit®运动能力水平的单一衡量指标和整体指示。此外，教练可以潜在地应用这个有用的工具来监测运动表现，并设计针对CrossFit®表现特定领域的训练课程。
