In the attempt to determine the least taxing of the methods of defecation using a bedpan in a supine, a bedpan in a 30° semirecumbent position and a bedside commode for the heart rate and oxygen consumption in 6 normal volunteers, we found the following: 1. The heart rate increased in actions before and after defecation in the same manner as in actions during defecation with either of the 3 meth-ods.

2. Cardiac stress due to actions before and after defecation was small with the use of a bedpan, but the duration of defecation was longer; associat-ed with more frequent straining efforts.

3. With the use of a bedpan in a 30° semire-cumbent position, cardiac stress, the duration of defecation and the frequency of straining efforts were the same as those with the use of a bedpan in a supine position. The method of using a bedpan in a 30° semirecumbent position does not seem advantageous over the method of using a bedpan in a supine position.

4. With the use of a bedside commode, cardiac stress was small during defecation, but oxygen con-sumption for pre- and post defecation's actions was larger than it with the use of a bedpan.

5. Metabolic equivalents (METS) during defeca-tion with either of the three methods was 2.0 or less and lower than literature data.
