劳动,除非其强度小,时间又短,一般总是会出现疲劳的。劳动后适度的疲劳,对机体并没有害处。但是,疲劳得不到及时恢复,而且产生的疲劳反复积累,形成所谓过度疲劳(以下简称过劳),则劳动能力和作业效率势必降低,甚至影响健康。因此,对部队医务人员来说,在训练与作业过程中的主要任务是防止战士过劳与过早地产生疲劳。 Labor, unless its strength is small, time is short, fatigue is generally always present. Moderate fatigue after work, no harm to the body. However, fatigue can not be recovered in time, and the resulting fatigue repeatedly accumulates, forming the so-called over-fatigue (hereinafter referred to as overwork), the working capacity and operational efficiency will inevitably be reduced, and even affect the health. Therefore, the main task of military medical personnel in training and operation is to prevent the soldiers from being overworked and prematurely exhausted.
