EXERCISE RECORDS FOR NORMAL SUBJECTS. 



Since both Squads A and B were upon reduced diet, A at maintenance 

 level, and B in a transitional stage, the primary object of this record 

 of activity was to find the influence, if any, of the reduced diet upon 

 the number of hours spent in the various activities other than sleeping 

 and sitting. Since both squads were on diet, the values for a squad 

 not undergoing dietetic restriction are of special interest. A group of 

 volunteers kindly offered to make records for a corresponding time. 

 The longest periods were from January 11 to February 3, but there 

 was considerable irregularity in the length of the record. Neverthe- 

 less, for most of the group, the picture is probably not far from true. 

 The results are recorded in table 196. The men were lying usually 

 not far from 8 hours, the most pronounced exception being that of 



^Chiefly gymnasium work; also skating, swimming, basket ball, running, hockey and dancing. 

 ^Chiefly hockey; also gymnasium work at college, leading gymnasium classes in public school, 



and shoveling snow. 

 'Chiefly shoveling coal; also basket ball, ice hockey, leading drill and games at Boy Scout 



meetings; 2 hrs. moving chairs.
