摘要
跨膈压的测定可间接反映呼吸肌肌力，故跨膈压可作为呼吸肌肌力训练前后的客观指标。本实验选择２３例无呼吸系统疾病的正常人，测定其跨膈压及最大跨膈压值，得到结果为：跨膈压值为２．２５±０．９７ｋＰａ，最大跨膈压值为５．０９±２．２４ｋＰａ，４０岁以下年龄组Ｐｄｉｍａｘ值较４０岁以上组高８．３９％，男性较女性高２７．４％，但统计学上无显著差异（Ｐ＞０．０５）。

contraction of breathing muscle can be indirectly assessed by
measuring transdiaphragmatic pressure (P di ). P di and P
dimax are the objective index before and after exercise trainning
of the breathing muscle. 23 cases without respiratory disease were
selected to measure the P di and P dimax . The results were:
P di =2 25±0 97kPa, P dimax =5 09±2 24kPa The P
dimax of man was 8 39% higher than woman. This pdimax in the group
of 21～40 years old were higher than the group of 41～62 (P>0 05).
