目的 了解中小学生背负重量行走时对其生理功能的影响。方法 以 6～ 1 4周岁儿童少年为研究对象 ,采用德国产JAEGEROxycon运动心肺功能测试系统 ,测定儿童少年背负不同重量行走时心率、呼吸频率、耗氧量等心肺功能指标及能量代谢的变化。结果 不同负重状态下儿童少年心率、呼吸频率、耗氧量及单位体重耗氧量、氧脉搏、呼吸商和能量消耗率均随着负重量的增加而逐渐增加。结论 负重对儿童少年心肺功能产生一定影响
Objective To understand the impact of primary and secondary school students carrying on their physiological function when carrying their weight. Methods Children and adolescents aged 6 ~ 14 years old were selected as research objects. Cardiopulmonary function indexes such as heart rate, respiratory rate, oxygen consumption and energy metabolism of children and adolescents were measured when they were carrying different weights. Results Heart rate, respiratory rate, oxygen consumption and body weight oxygen consumption, oxygen pulse rate, respiratory quotient and energy consumption rate of children and adolescents with different weight-bearing status increased with the increase of negative weight. Conclusion Weight-bearing children and adolescents have some impact on cardiopulmonary function
