概括

运动员在重复的CrossFit® Open (CFO) 训练中提高了表现,尤其是女性运动员. 然而,参与率的增加使得整体排名的提高变得更加困难,需要比领域平均水平更快的个人收益.

科学领域:

运动科学运动科学运动科学
运动生理学运动生理学
竞争能力分析竞争能力分析

背景情况:

克罗斯菲特®公开赛 (CFO) 是年度克罗斯菲特®运动会的初步竞争阶段.
炼旨在挑战举重,体操和耐力,男性和女性都有类似的设计.
每年重复一次训练 (2012-2021年),允许随着时间的推移进行性能比较.

研究的目的:

在重复的CFO训练中分析基于性别的绩效变化差异.
调查这些变化对整体和训练特定排名的影响.

主要方法:

分析了11000名运动员 (每年500名男性,500名女性) 在9次重复的CFO训练 (2011-2021) 中的数据.
从公共排名表收集运动员年龄,总体排名和炼成绩.
将所有分数转换为重复完成率 (重复/分钟时间) 以进行标准化比较.

主要成果:

在9次重复训练中的7次中,观察到显著的性能改善 (平均增加14.3%).
男性最初在更多的炼中表现出更快的时间,但女性在重复的实例中表现出显著的改善.
尽管表现有所提高,但由于竞争加剧,运动员在整体和训练中排名较低.

结论:

大多数运动员,特别是女性,在重复的CrossFit®开放训练中提高了他们的表现.
参与度的增加和平均绩效的提高使得更高的排名更具挑战性.
个体运动员必须超过平均场地改进,以提高他们的竞争地位.

Exercise and Muscle Performance

Exercise and Muscle Performance

Exercise induces a range of adaptations in muscle tissue, depending on the type and duration of activity. Such physical training can be broadly categorized into two types: endurance exercises and resistance exercises.
Endurance exercises
Endurance exercises involve running, swimming, or cycling, which require repetitive movements with low force output. When a person engages in endurance exercise, a few noticeable changes occur in their skeletal muscles. For instance, the number of capillaries...

Wilcoxon Signed-Ranks Test for Median of Single Population

Wilcoxon Signed-Ranks Test for Median of Single Population

The Wilcoxon signed-rank test for the median of a single population is a nonparametric test used to evaluate whether the median of a population differs from a specified value. Unlike parametric tests, it does not require data to follow a normal distribution, making it suitable for non-normal or small samples. The test begins by calculating the difference (d) between each observation and the hypothesized median. The absolute values of these differences are ranked in ascending order, with ties...
