The benefit of protective headgear for recreational skiers is an ongoing debate in the snow sports industry, and there are a lot of opposing opinions. Due to the dynamic conditions in which winter sports are performed, athletes demand rapid and constant processing of visual information. A sufficient level of anticipation helps athletes to properly position themselves to reduce the forces transferred to the head or even move to avoid a collision. To objectively identify the impact of protective headgear on the visual field when skiing, it is necessary to conduct suitable measurements. The sample consisted of 43 recreational-level skiers (27 M, 16 F; age 31.6 ± 8.23 years). A predefined testing protocol on an ortoreter was used to assess the visual field for three conditions of wearing protective headgear. Differences in perceived visual stimuli between the three conditions were evaluated by repeated measures analysis of variance (ANOVA). Based on the observed results, it can be concluded that the combination of wearing a ski helmet and ski goggles significantly negatively influences visual performance in a way that the visual field is narrowed, for both helmet users and non-users, only when comparing the tested conditions. When comparing helmet users and non-users, there are no differences in the amount of visual impairment; therefore, the habit of wearing a helmet does not influence the ability of perceiving visual stimuli.
在滑雪运动行业中,对于防护性头盔对娱乐性滑雪者的益处一直存在争议,并且存在很多相反的观点。由于冬季运动是在动态条件下进行的,运动员需要快速且持续地处理视觉信息。足够的预判能力有助于运动员正确调整自己的位置,以减少传递到头部的力,甚至可以移动以避免碰撞。为了客观地识别防护性头盔对滑雪时视野的影响,有必要进行适当的测量。该样本由 43 名娱乐级滑雪者(27 名男性,16 名女性;年龄 31.6±8.23 岁)组成。使用 ortoreter 上的预设测试方案来评估佩戴防护性头盔的三种情况下的视野。通过重复测量方差分析(ANOVA)评估三种情况下感知到的视觉刺激之间的差异。基于观察到的结果,可以得出结论,滑雪头盔和滑雪护目镜的组合会显著地以缩小视野的方式对视觉表现产生负面影响,对于头盔使用者和非使用者来说,只有在比较测试条件时才会出现这种情况。在比较头盔使用者和非使用者时,在视觉障碍程度上没有差异;因此,佩戴头盔的习惯不会影响感知视觉刺激的能力。
