In the trend sport CrossFit, international competition is held at the CrossFit Games, known worldwide as the definitive fitness test. Since American athletes are the best in the world regarding CrossFit, there might be influencing factors on international competition performance. Here, we characterize the benchmark performance profile of American and German CrossFit athletes (n = 162). To collect the common benchmark performance by questionnaire, 66 male and 96 female CrossFit athletes (32.6 ± 8.2 years) participated in our survey in both nations. By comparing the individual performance variables, only a significant difference in total power lift performance by males was identified between the nations ( = 0.034). No other significant differences were found in the Olympic lift, running, or the "Girl" Workout of the Day (Fran, Grace, Helen) performance. Very large to extremely large (r = 0.79-0.99, < 0.01) positive correlations were found between the power lift and Olympic lift variables. Further linear regression analysis predicted the influence of back squat performance on performance in the Olympic lifts, snatch (R = 0.76) and clean and jerk (R = 0.84). Our results suggested a dominant role of back squat performance in the assessment of physical fitness of CrossFit athletes.
在潮流运动CrossFit中，国际比赛在CrossFit运动会上举行，该运动会作为终极体能测试而闻名于世。由于美国运动员在CrossFit项目上是世界上最优秀的，因此可能存在影响国际比赛成绩的因素。在此，我们对美国和德国CrossFit运动员（n = 162）的基准成绩概况进行了描述。为了通过问卷调查收集常见的基准成绩，两国共有66名男性和96名女性CrossFit运动员（32.6 ± 8.2岁）参与了我们的调查。通过比较个体成绩变量，发现两国之间仅男性的总力量举成绩存在显著差异（ = 0.034）。在奥林匹克举重、跑步或当日的“女子”训练项目（Fran、Grace、Helen）成绩方面未发现其他显著差异。在力量举和奥林匹克举重变量之间发现了非常大到极其大的正相关（r = 0.79 - 0.99， < 0.01）。进一步的线性回归分析预测了后深蹲成绩对奥林匹克举重项目中抓举（R = 0.76）和挺举（R = 0.84）成绩的影响。我们的结果表明，后深蹲成绩在评估CrossFit运动员体能方面起主导作用。
