概括
与替补球员相比,大学足球队的首发球员积累了更多的季节性工作负载,包括总距离和高速跑步. 然而,整体训练负载和每分钟的比赛负载在各组之间是相似的.
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
- 足球表现分析 足球表现分析
背景情况:
- 了解球员的工作量对于优化训练和预防大学田径运动中的受伤至关重要.
- 首发球员和替补球员之间的比赛时间差异可能导致累积的身体需求差异.
- 之前的研究已经探讨了工作负载量化,但女性大学足球中的具体比较不那么明确.
研究的目的:
- 为了量化女性大学足球运动员在一个竞争赛季的累积工作负载.
- 为了比较首发球员和替补球员之间的季节性工作量.
- 根据玩家角色,识别培训和匹配需求的潜在差异.
主要方法:
- 利用全球定位系统 (GPS) 和心率 (HR) 监测传感器对19名女大学足球运动员进行监测.
- 收集了2019年整个赛季的总距离,速度距离和HR区域以及加速的数据.
- 雇员重复测量ANOVA和学生的t测试来分析初始和替代品之间的差异.
主要成果:
- 与替代品相比,起跑者季节累积总距离,冲刺距离和高速距离显著增加 (p < 0.001).
- 在首发球员和替补球员之间的积累训练负载 (p = 0.08) 或在比赛中每分钟的训练负载 (p = 0.08) 中没有发现显著差异.
- 替补队员在训练期间表现出类似的工作负载,但在比赛中与替补队员相比,在比赛中表现出明显的差异.
结论:
- 在女子大学足球赛的竞争赛季中,首发球员在整体上体验到更高的体力要求.
- 虽然总比赛曝光率不同,但每分钟的强度可能是相似的,这表明了战略替换模式.
- 教练和从业人员应实施有针对性的监测,以解决初学者和替代者之间的工作负载差异.

Standard Deviation
16.9K
The most commonly used measure of variation is the standard deviation. It is a numerical value measuring how far data values are from their mean. The standard deviation value is small when the data are concentrated close to the mean, exhibiting slight variation or spread. The standard deviation value is never negative, it is either positive or zero. The standard deviation is larger when the data values are more spread out from the mean, which means the data values are exhibiting more variation.

One-Way ANOVA: Equal Sample Sizes
3.3K
One-Way ANOVA can be performed on three or more samples with equal or unequal sample sizes. When one-way ANOVA is performed on two datasets with samples of equal sizes, it can be easily observed that the computed F statistic is highly sensitive to the sample mean.
Different sample means can result in different values for the variance estimate: variance between samples. This is because the variance between samples is calculated as the product of the sample size and the variance between the...

Social Facilitation
32.0K
Not all intergroup interactions lead to negative outcomes. Sometimes, being in a group situation can improve performance. Social facilitation occurs when an individual performs better when an audience is watching than when the individual performs the behavior alone. This typically occurs when people are performing a task for which they are skilled.

One-Way ANOVA: Unequal Sample Sizes
5.8K
One-way ANOVA can be performed on three or more samples of unequal sizes. However, calculations get complicated when sample sizes are not always the same. So, while performing ANOVA with unequal samples size, the following equation is used:
