Abstract
In order to observe the respiration curve and the electromyogram (E. M. G.) in practising “Naminui” sewing, and to examine the relation between the two, some experiments were made on pupils of elementary and lower secondary schools and some ordinary female adults. The bioelectric amplifier and the ink oscillograph were used as instruments, with electrodes attached to their forearm muscles. The results are as follows :
1. As for the “experienced”, a rhythmical pattern was observed both in the respiration curve and in the E. M. G., and there was some correlation between them.
2. The analysis of the data obtained from the experiments in “Naminui” sewing showed that, while the numeral values for lower secondary school pupils are close to those for adults, there was a wide gap between elementary school pupils and adults.
3. The evaluation based on this experiment approximately corresponded with that of the work itself.
