探讨不同海拔高度和不同步速条件下的适宜负重，对于确定高原作业人员合理负重有指导意义。本工作通过高原模拟负重步行试验（跑台）提出适宜负重。在海拔３７００ｍ，步行速度分为４．０、４．５和５．０ｋｍ／ｈ；负重分别为体重的０、１４％、２１％、２８％、３５％和４２％。在海拔４３００ｍ，步行速度分别为３．０、３．５和４．０ｋｍ／ｈ；负重分别为体重的Ｏ、１４％、２１％、２８％、３５％。在海拔５２００ｍ，步行速度分别为２．０、２．５和３．０ｋｍ／ｈ；负重分别为体重的０、７％、１４％、２１％、２８％和３５％。在每个海拔高度上选择移居半年以上的青年学生１２人作为受试对象。每人参加不同速度与不同负重步行试验。根据很累感发生率、ＶＥ、ＨＲ、恢复ＨＲ和Ｅ的改变确定适宜负重。结果表明，在海拔３７００ｍ，速度为４．０、４．５和５．０ｋｍ／ｈ时的适宜负重分别为２０．８、１７．４和１４．１ｋｇ。在海拔４３００ｍ，速度为３．０、３．５和４．０ｋｍ／ｈ时的适宜负重分别为１８．４、１４．３和１０．２ｋｇ。在海拔５２００ｍ，速度为２．０、２．５和３．０ｋｍ／ｈ时的适宜负重分别１７．３、１４．２和１１．４ｋｇ。
It is instructive to study the suitable load under different altitude and different pace conditions to determine the reasonable load of altitude operators. This work through the plateau walk load test (treadmill) proposed suitable load. At an altitude of 3700 m, the walking speed was divided into 4.0, 4.5 and 5.0 km / h; the weights were 0, 14, 21, 28, 35 and 42% of body weight, respectively. At an altitude of 4300m, the walking speed was 3.0, 3.5 and 4.0km / h, respectively; the weights were O, 14%, 21%, 28% and 35% of body weight, respectively. At 5200 m above sea level, the walking speed was 2.0, 2.5 and 3.0 km / h, respectively. The weights were 0, 7, 14, 21, 28 and 35% of body weight, respectively. Twelve young students who chose to migrate for more than six months at each altitude were selected as subjects. Each person to participate in different speeds and different weight walking test. According to the incidence of very tired feeling, VE, HR, restore HR and E changes to determine the appropriate weight. The results showed that the suitable loads at the speeds of 4.0, 4.5 and 5.0 km / h at an altitude of 3700 m were 20.8, 17.4 and 14.1 kg respectively. The suitable weights at speeds of 3.0, 3.5 and 4.0 km / h at an altitude of 4300 m were 18.4, 14.3 and 10.2 kg, respectively. At an altitude of 5200 m and at speeds of 2.0, 2.5 and 3.0 km / h, the appropriate weights were 17.3, 14.2 and 11.4 kg, respectively.
