COMPARISON OF THE ACTIVITIES OF SQUADS A AND B, AND THE NORMAL 



GROUP. 



We have collected in table 197 the average values found with the 

 various subjects in Squads A and B, and for the group of normal sub- 

 jects, for the houjs of walking and for the activity greater than walk- 

 ing, as these are the two factors that play the greatest role in indicating 

 changes in physical activity. With both Squads A and B, the average 

 time spent in walking was 4j hours, and with the normal subjects, 

 4f hours. For the activity greater than walking we find reasonable 

 uniformity with all three squads, namely, 1^ hours with Squad A, 

 and 1| hours for both Squad B and the normal group. The general 

 picture of the data given in table 197 shows that the activities as 

 measured by the time spent in walking or in exercise greater than 

 walking were not strikingly different with any of the three groups. 

 For Squad A the exercise more strenuous than walking is slightly lower 

 by one-quarter hour per man per day, but the real significance, if any, 

 of this small difference can not be determined. 



It therefore seems from a study of the pedometer records and of the 

 relatively small differences exhibited by the men in their records of
