夏季,部队进行游泳和泅渡训练中必须注意卫生,预防发生疾病、溺水和外伤事故。因此,认真做好游泳和泅渡训练中的卫生保障工作是很重要的。一、游泳和泅渡对机体的影响 1.能量消耗大:游泳和泅渡时,机体完全在水中活动,为克服水的阻力和压力,使大量的肌群和内脏参加作功;由于水的理化特性对人体有很大影响,水温一般低于体温,体热放散快,能量消耗要比在陆地训练时大。我区某部在热带地区泅渡训练时,测得的能量消耗为3.415～5.591卡/平方米、分,故泅渡是一项重体力劳动。能量消耗的大小与游泳姿势,技巧的熟练程度、适应与习服过程的长短、泅渡时负荷的轻重、流速、逆水或顺水、波浪大小等有关。 2.改善体温调节机能:表现为皮肤血管的舒缩反应灵敏;能量代谢增高;产热和散热的调节机能加强,既能在冷水中活动保持体温不下降,又有利于对冷热气候的适应。
In the summer, the troops must pay attention to hygiene in swimming and cross-cutting training to prevent diseases, drowning and traumatic accidents. Therefore, it is important to do a good job in health care in swimming and cross-training. First, the swimming and the transition on the impact of the body 1. Energy consumption: Swimming and swagger, the body fully in the water activities, in order to overcome the water resistance and pressure, so that a large number of muscles and organs to participate in the work; due to the physical and chemical properties of water Has a great impact on the human body, the water temperature is generally lower than body temperature, body heat quickly dissipated, energy consumption than in land training large. When a certain department of our district took over training in the tropics, the measured energy consumption was 3.415-5.891 calories per square meter, so it is a heavy manual labor. The size of the energy consumption and swimming posture, skill proficiency, accustomed to and accustomed to the length of the process, when crossing the load of the severity, velocity, reverse or smooth water, wave size and so on. 2. To improve the function of body temperature regulation: the performance of skin and vasomotor sensitivity and responsiveness; increased energy metabolism; heat and cooling regulation of the role of strengthening, both in cold water activity to maintain body temperature does not decline, but also conducive to the hot and cold climate adaptation .
