Abstract

: Drownings are a societal phenomenon occurring worldwide, hence the importance of rescue skills, including directly towing a victim to a safe place. The purpose of this study was to evaluate the most effective towing techniques based on kinematic parameters, considering different types of drowning cases, for their recommendation for widespread use in water rescue. : The research involved 18 water lifeguards aged 18-25 years. The evaluation included speed tests in towing a mannequin over a distance of 50 m using the Extended Arm Tow (EAT), Double Armpit Tow (DAT), "Sailor" Technique Tow (STT) and with a rescue tube (RT), accompanied by video recording to measure in the designated measurement area the number of cyclic paddling movements by the lower limbs, angles of the body attack, towing velocity, and its decrease during towing. : Number of cyclic paddling movements by the lower limbs, towing with a RT was considered the most beneficial, and least beneficial was the DAT. In the DAT, the lifeguard swam with the smallest body angle, in contrast to the STT, where this angle was the largest. The effect of the number of cyclic paddling movements and the body angle by the lifeguard was the velocity, with the highest value recorded in towing using a RT; in other techniques, velocity were similar. : Institutions associated with water rescue should recommend towing using a RT for direct rescue actions in the water, as its use shortens the time, while simultaneously increasing safety for both the rescuer and the victim.

摘要

溺水是一种在全球范围内发生的社会现象,因此救援技能非常重要,包括直接将受害者拖到安全的地方。本研究的目的是评估基于运动学参数的最有效的拖曳技术,考虑到不同类型的溺水情况,为其在水上救援中的广泛应用提供建议。

研究涉及 18 名 18-25 岁的水上救生员。评估包括使用伸展臂拖曳(EAT)、双腋窝拖曳(DAT)、“水手”技术拖曳(STT)和救援管(RT)在 50 米距离内拖曳人体模型的速度测试,同时进行视频记录,以测量指定测量区域内下肢的划水次数、身体攻击角度、拖曳速度及其在拖曳过程中的下降。

下肢划水次数,使用 RT 拖曳被认为是最有益的,而 DAT 则是最不利的。在 DAT 中,救生员游泳的身体角度最小,而在 STT 中,这个角度最大。救生员下肢划水次数和身体角度的效果是速度,使用 RT 拖曳时记录的速度最高;在其他技术中,速度相似。

与水上救援相关的机构应该建议在水中直接救援行动中使用 RT 拖曳,因为它缩短了时间,同时提高了救援人员和受害者的安全性。
