648 VITALITY AND EFFICIENCY WITH RESTRICTED DIET. 



about evenly divided in their make-up between men who were 

 taking the course in physical education and those who were taking 

 the secretarial course. As a matter of fact, Squad A had, excluding 

 Fre, 7 men taking the physical course and 5 taking the secretarial 

 course, while with Squad B, 9 were taking the physical course and 3 

 the secretarial course. Undue prominence, however, should not be 

 given to this classification, for it is by no means sure that the activities 

 of the men taking the physical course were very much, if any, greater 

 than those of the subjects taking the secretarial course. 



COMPARISON OF PEDOMETER RECORDS, SQUAD A, WITH THOSE FOR SQUAD B 



ON NORMAL DIET. 



The normal values obtained for Squad B are recorded in the first line of 

 table 193, with an average of 6.24 miles per day. Comparing this average 

 value, obtained when the subjects were on normal diet, with those 

 obtained with Squad A on reduced diet (see table 192) it can be seen that 

 this is not far from a roughly average figure shown by the latter squad. 

 If anything, it is slightly lower than those obtained when Squad A was 

 at maintenance level, namely, December 13 to 19, and the latter part of 

 January. We believe that this is tolerably good evidence that Squad 

 A was not exercising less, at least so far as the pedometer records are 

 concerned, than the average college student of the undergraduate 

 body. Emphasis should again be laid upon the fact that Squad B was 

 on normal diet, as the men were not put upon reduced rations until 

 January 8. The evidence, therefore, as supplied by the pedometer 

 records, is clearly to the effect that Squad A, after the first two weeks, 

 maintained a level of walking which was perfectly comparable, even 

 when on low diet, to that maintained by Squad B on a normal diet 

 with very much larger energy content. 



While the closest attempt to secure quantitative measurements of 

 physical activity by means of pedometers leads to the above findings, 

 yet, in view of the defective nature of the pedometer units, an analysis 

 of the probable physical activities, particularly those other than walk- 

 ing, is essential before the final decision can be made as to whether or 

 not Squad A materially altered their physical activity as compared 

 to that of the average undergraduate in the Y. M. C. A. College. 



PEDOMETER RECORDS FOR SQUAD B WITH REDUCED DIET. 



The pedometer records for Squad B are given in table 193, together 

 with the normal values obtained on December 13 to 19. In considering 

 these, it is important to bear in mind that the observations made on 

 Squad B comprise solely those during a transitional period. The 

 average number of miles during the first week of reduced diet is prac- 

 tically uniform with that on normal diet, but the pronounced fall in 

 the subsequent two values is worthy of emphasis and is clearly to be 

 ascribed to the very severe reduction in diet which took place.
