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
- 生物机械分析 生物机械分析
背景情况:
- 速度-持续关系对于预测运动表现和描述跑步者的特点至关重要.
- 临界速度 (CS) 和功率定律 (PL) 模型通常由实践者使用.
- 需要使用多层模型 (MLMs) 的比较分析来评估这些模型.
研究的目的:
- 为了比较PL和CS模型的性能预测准确度.
- 评估PL和CS模型的运动员表征能力.
- 为了利用多层次模型 (MLMs) 中长距离跑步者.
主要方法:
- 分析了来自52,847名运动员的184,755次表现,涉及6项跑步比赛 (400米-10,000米).
- 开发了MLM计算层次数据结构的发展.
- 使用平均绝对误差 (MAE) 和平均绝对相对误差 (MARE) 评估预测准确性.
- 通过模型衍生的参数来表征运动员:速度 (S),耐力 (E),无氧能力 (D') 和CS.
主要成果:
- 比起CS MLM (MAREtime = 6.87%,MAREpeed = 9.1%),PL MLM的预测准确度显著更高 (MAREtime = 1.32%,MAREpeed = 1.32%) 的结果是可以预测的.
- 长途跑者显示出更高的E和CS;中距离跑者显示出更高的S.
- 专业化,性别和绩效水平影响了模型衍生的参数 (S,E,D',CS).
结论:
- 多媒体营销提供了对跨运动员群体,性别和绩效水平的速度-持续关系的增强理解.
- 模型衍生参数为全面的运动员分析提供了宝贵的见解.
- PL MLM被认为是预测运行性能的可靠和准确工具.
