摘要

目的确定滑雪者和单板滑雪板运动员在美国滑雪道上的典型速度。设计和方法在美国8个滑雪区的不同难度的滑雪道上测量滑雪者的坡面速度。记录每个速度测量位置的滑雪道难度名称和坡度。记录了雪上运动参与者使用的设备(滑雪板或单板滑雪板)、是否戴头盔以及估计的能力(由研究人员确定)。进行了多元线性回归分析,以确定这些个人和环境因素对雪上运动参与者速度的影响。结果2004年至2020年间,在代表美国5个地理区域的8个滑雪区的整洁小径上进行了4164次速度观测。在所有观测中,平均速度为34.9​±​13.6​公里/小时。雪上运动参与者的能力对速度的影响最大。高级雪上运动参与者的速度更快(44.5​±​11.7​km/h)高于中间体(32.4​±​9.9)和初学者(19.9​±​7.2)。滑雪者平均速度更快(35.8​±​13.8​km/h)高于单板滑雪运动员(33.0​±​13.2​km/h),初学者和中级滑雪板运动员的平均速度比他们的滑雪同行慢。虽然平均速度随着越野难度和坡度的增加而增加,但相关性较弱(R2​=​0.15)。结论雪上运动参与者的能力是影响速度的最大因素。

Skier and snowboarder speeds at US ski areas

Objectives

To determine typical speeds of skiers and snowboarders on-piste groomed trails across the United States (US).

Design and methods

On-slope speeds of skiers and snowboarders were measured on trails of varying difficulty at 8 ski areas across the US. The trail difficulty designation and slope were documented for each location where speed measurements were taken. The equipment used (skis or snowboard), whether a helmet was worn, and the estimated ability (determined by the researchers) of snowsports participants were recorded. A multiple linear regression analysis was performed to determine the influence of these individual and environmental factors on the speeds of snowsports participants.

Results

4164 speed observations were made between 2004 and 2020 on groomed trails at 8 ski areas representing 5 geographic regions in the United States. Across all observations, the average speed was 34.9 ​± ​13.6 ​km/h. The ability of the snowsports participant had the largest effect on speed. Advanced snowsports participants traveled faster (44.5 ​± ​11.7 ​km/h) than intermediates (32.4 ​± ​9.9) and beginners (19.9 ​± ​7.2). Skiers on average were faster (35.8 ​± ​13.8 ​km/h) than snowboarders (33.0 ​± ​13.2 ​km/h) and beginner and intermediate snowboarders were slower on average than their skiing counterparts. While the average speeds increased with increasing trail difficulty and slope, the correlation was weak (R2 ​= ​0.15).

Conclusions

The ability of the snowsports participant was found to be the most influential factor affecting speed.
