概括
各国根据骑自行车者的身材和风景表现出了专业骑自行车的专业化. 较轻的骑自行车者在大巡回赛 (GC) 和登中表现出色,而较重的骑自行车者与较少的山地地形有关,这表明选择偏差.
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
- 骑自行车的性能分析
背景情况:
- 调查了男性专业道路自行车运动的全国专业化,跨越了登,冲刺,计时赛 (TT) 和大巡回赛 (GC) 等学科.
- 检查了乡村景观 (如山地) 和骑自行车的人类测量 (如体重,身高) 之间的潜在联系.
研究的目的:
- 确定国家自行车队是否专注于特定的比赛专业化.
- 探索一个国家的地理特征与其职业自行车手的身体特征之间的关系.
- 了解职业自行车运动中潜在的选择偏见.
主要方法:
- 收集了来自15个国家的1810名骑自行车者的体重,身高和ProCyclingStats (PCS) 积分.
- 评估了每个国家的海拔范围,以代表景观特征.
- 标准化身高和使用体重指数 (BMI) 来纠正各国之间的体重差异.
主要成果:
- 平均人体测量 (体重,身高) 与GC,冲刺和登学科的PCS积分相关,表明国家专业化.
- 较短,较轻的骑自行车者往往在GC和登中表现更好;较重的骑自行车者在冲刺中表现更好.
- 在人类计量和时间试验 (TT) 或一天比赛中的表现之间没有发现显著的关系.
- 骑自行车的人数较多的国家通常具有较少的山地景观.
结论:
- 结果表明,在职业自行车运动中存在选择偏见,有利于特定的身体类型,适合特定的地形.
- 国家景观似乎影响了骑自行车者的发展和专业化.
- 这种偏见可能会导致那些不符合当前国家形象的有才华的自行车手错过机会.

47
The alignment of a road line using Geographic Information Systems (GIS) is a critical process in civil engineering, combining advanced technology with practical decision-making. This methodology begins with the collection of geospatial data, including information on land cover, geomorphology, drainage patterns, slope, and contour details. Such data is typically acquired through satellite imagery and GIS tools, offering a comprehensive understanding of the terrain.Once the data is gathered, it...

202
Profile leveling and cross-sections are surveying methods used to determine and document terrain elevations for infrastructure projects such as highways, railroads, canals, and pipelines. These methods provide data for earthwork planning and alignment of proposed routes. Profile leveling involves measuring elevations along a fixed line to create a vertical terrain profile. A surveyor sets up a leveling instrument at the benchmark (BM) and records a backsight (BS) to determine the...

Topography involves measuring and mapping land elevations, natural features, and artificial structures to create accurate representations of the terrain. Topographic surveying relies on traditional and modern methods, each with distinct advantages and limitations.Traditional Surveying Methods:Transit stadia surveys and plane table surveys were widely used traditional surveying methods. These techniques relied on instruments like theodolites and stadia rods for measuring distances and angles,...
