To examine the relationships between past competition performances and 2020 CrossFit® Open (CFO) performance.
A random selection from the top one thousand athletes (n = 220, 28.5 ± 4.4 years, 178 ± 7 cm, 87.5 ± 10.2 kg) were selected for this study. Overall and weekly performances (including ranks and scores) of the 2020 CFO, as well as overall ranks from all previous CFO, regional, and Games™ competitions in which they competed, were recorded from their publicly available online profile. The highest, lowest, average, and standard deviation (SD) of past rankings, as well as participation statistics (i.e., years since first appearance, total and consecutive appearances, and participation rate), were calculated for each competition stage. Relationships were then assessed between 2020 CFO performance and all past competition experience variables by calculating Kendall's tau (τ) correlation coefficients and Bayes factors (BF).
Overall and weekly ranking of the 2020 CFO was extremely favored (p < 0.001, BF > 100) to be related to the athlete's highest previous CFO rank (τ = 0.26-0.39) and individual regional appearances (τ = - 0.26 to - 0.34), as well as individual Games™ appearances (overall and for weeks 1, 3, and 4; τ = - 0.20 to - 0.22, p < 0.001, BF > 100). Evidence for all other significant relationships ranged from moderate to very strong (p < 0.05, BF = 3-100) and varied among specific 2020 CFO workouts. Few associations were noted for team competition experience, and these were generally limited to Games™ appearances (τ = - 0.12 to - 0.18, p < 0.05, BF = 3.3-100).
Although specific relationships were found between 2020 CFO performance and individual appearances at regional and Games™ competitions, the most consistent relationships were seen with participation and ranking in past CFO competitions.
研究过去的比赛成绩与2020年CrossFit®公开赛(CFO)成绩之间的关系。
从排名前一千的运动员中随机选取(n = 220,年龄28.5±4.4岁,身高178±7厘米,体重87.5±10.2千克)进行本研究。2020年CFO的总体和每周成绩(包括排名和分数),以及他们参加过的所有之前的CFO、地区赛和运动会™比赛的总体排名,均从其公开的在线资料中记录。计算每个比赛阶段过去排名的最高值、最低值、平均值和标准差(SD),以及参赛统计数据(即首次参赛以来的年份、总参赛次数和连续参赛次数以及参赛率)。然后通过计算肯德尔tau(τ)相关系数和贝叶斯因子(BF)来评估2020年CFO成绩与所有过去比赛经验变量之间的关系。
2020年CFO的总体和每周排名极有可能(p < 0.001,BF > 100)与运动员之前在CFO的最高排名(τ = 0.26 - 0.39)、个人地区赛参赛经历(τ = -0.26至-0.34)以及个人运动会™参赛经历(总体以及第1、3和4周;τ = -0.20至-0.22,p < 0.001,BF > 100)相关。所有其他显著关系的证据从中度到非常强(p < 0.05,BF = 3 - 100)不等,并且在2020年CFO的特定训练项目中有所不同。团队比赛经验的关联较少,且通常仅限于运动会™参赛经历(τ = -0.12至-0.18,p < 0.05,BF = 3.3 - 100)。
虽然发现2020年CFO成绩与地区赛和运动会™比赛的个人参赛经历之间存在特定关系,但最一致的关系是与过去CFO比赛的参赛情况和排名有关。
