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 (p = 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, p < 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 (R2 = 0.76) and clean and jerk (R2 = 0.84). Our results suggested a dominant role of back squat performance in the assessment of physical fitness of CrossFit® athletes.

确定 CrossFit® 基准性能概况

在潮流运动CrossFit ® 中,国际比赛在CrossFit ®运动会举行,该运动会在世界范围内被称为权威的体能测试。由于美国运动员在 CrossFit ®方面是世界上最好的,因此可能存在影响国际比赛成绩的因素。在这里,我们描述了美国和德国 CrossFit ®运动员(n = 162)的基准表现概况。为了通过问卷收集共同的基准表现,66 名男性和 96 名女性 CrossFit ®运动员(32.6 ± 8.2 岁)参加了我们在两国的调查。通过比较个人的表现变量,只有男性在总力量举表现上的显着差异被发现在国家之间(p = 0.034)。在奥林匹克举重、跑步或每日“女孩”锻炼(弗兰、格蕾丝、海伦)的表现中没有发现其他显着差异。在力量举和奥林匹克举变量之间发现非常大到非常大(r = 0.79–0.99,p < 0.01)正相关。进一步的线性回归分析预测了后蹲表现对奥林匹克举重、抓举 (R 2 = 0.76) 和挺举 (R 2 = 0.84) 表现的影响。我们的结果表明,深蹲表现在 CrossFit ®运动员体能评估中起主导作用。
