EXPERIMENTS WITH SUBJECT STANDING. 



Ill 



day 91 beats per minute. With the other two subjects the data are 

 sufficient to give a picture which is probably truer than that of T. H. H., 

 these showing a percentage increase of 34 to 39 per cent for standing as 

 compared with the rates found for the lying position. 



In a publication recently issued from the Nutrition Laboratory, 1 

 some data were given on the change in the pulse-rate with two groups 

 of 11 men each, one of these groups (Squad A) being on a reduced diet 

 with a very much lowered basal metabolism, and the other (Squad B) 

 on a normal diet. From the figures in table 26, it is seen that the pulse- 

 rate of Squad A on a reduced diet increased 38 per cent for the standing 

 position as compared with that found when the men were lying down. 

 With the men in Squad B on normal diet, the pulse-rate for the standing 

 position showed an increase of 32 per cent. These figures agree with 

 those reported for the subj ects of the present research. From the above 

 comparison it may be said that the work of standing increases the 

 pulse-rate approximately 35 per cent over that for the lying position.

To note the changes in pulse-rate within the period, detailed data 

 for the standing experiments of W. K. have been collected in table 27. 

 The records were usually made at the second, sixth, and tenth minutes 

 of the period. The pulse-rates obtained in the walking experiments on 

 the same dates are also included. Table 27 likewise shows a few rates 

 which were determined preliminary to the periods, in intervals between 

 periods, and when the subject was standing after walking.
