Total- and vital capacity (TC, VC), FIV1, FEV1 and airway resistance were determined in 45 boys and 44 girls aged 8 to 12 years with the aid of body-plethysmography. 2. VC correlates best with body height. Boys have a 200 ml greater VC than girls. Beginning with 12 to 13 years, age is an additional factor modifying VC. 3. The ratio VC/TC averages 0.835 in boys and 0.824 in girls, the ratio is independent of the VC. 4. Airway resistance is appreciably higher than in adults and decreases with rising VC and body growth. 5. FIV1 is 87%, FEV1 is 80% of VC. These values are independent of sex and VC.
借助体容积描记法对45名8至12岁男孩和44名8至12岁女孩测定了肺总量和肺活量（TC、VC）、用力吸气量（FIV1）、第一秒用力呼气量（FEV1）以及气道阻力。2. 肺活量与身高的相关性最佳。男孩的肺活量比女孩大200毫升。从12至13岁开始，年龄是影响肺活量的另一个因素。3. 肺活量与肺总量的比值，男孩平均为0.835，女孩平均为0.824，该比值与肺活量无关。4. 气道阻力明显高于成年人，并随肺活量增加和身体生长而降低。5. 用力吸气量为肺活量的87%，第一秒用力呼气量为肺活量的80%。这些数值与性别和肺活量无关。
