Serum glucose and lactic acid levels were determined in 20 young volunteers prior to and following marches with increasing back pack loads (30 and 35 kg) and distances (6 and 12 km). The drop in serum glucose levels correlated well with the degree of effort. A significant mean drop in serum glucose level of 10.3 mg% was detected only in the group carrying 35 kg for a distance of 12 km. In this group, objective physiological parameters as well as subjective grading of the march's difficulty indicated the effort to be strenuous. Serum lactic acid level did not change significantly following any march. Serum glucose level may serve an indicator for determination of work's duration and intensity, determination of optimal distances for untrained hikers and of optimal loads to be carried for various distances.
在20名年轻志愿者背负逐渐增加的背包重量（30千克和35千克）并行走不同距离（6千米和12千米）的行军前后，测定了他们的血清葡萄糖和乳酸水平。血清葡萄糖水平的下降与努力程度密切相关。仅在背负35千克行走12千米的组中，检测到血清葡萄糖水平平均显著下降了10.3毫克%。在该组中，客观生理参数以及行军难度的主观分级均表明努力程度很大。在任何一次行军后，血清乳酸水平均未发生显著变化。血清葡萄糖水平可作为确定工作持续时间和强度、确定未经训练的徒步旅行者的最佳距离以及不同距离所应背负的最佳负荷的一个指标。
