The records for Squad A are given in table 194. They were kept for most of the time from January 11 until February 2 or 3, inclusive. Although the men endeavored as far as possible to classify their activities, and it can be seen that commonly there was uniform regularity in so doing, it is obvious on individual days there may be rather gross deviations from the exact facts. On the whole, however, the picture of all members of Squad A may be taken as indicative of their activity during this period. The records in the table are given on the quarter-hour basis.

Lying

An examination of table 194 shows that usually the men were lying not far from 8 to 9 hours per day. The exception to this was Gul, whose average figure shows but 4 1/2 hours. Gul, throughout the entire period of observation, was referred to frequently by all members of the squad and by other men in the college as being the "hardest worked man in college." We may record here that no other man in the squad was observed to be more often dozing or nodding, when unemployed and sitting in a chair in the library at the Nutrition Laboratory and at other times. It would therefore appear as if the 4 1/2 hours lying was a low estimate for the resting of this man. In consequence, the estimates for sitting and walking must be somewhat high. It is unnecessary to go into the individual figures to show how the different men vary from day to day, but only to say that the lying values are for the most part remarkably uniform, aside from those for Gul.

Sitting

With the striking exception of Pea, who reports an average of but 5 3/4 hours sitting, and Gul, who reports but 7 3/4 hours, the men in Squad A showed, on the average, a sitting value not far from 10 to 12 hours.

Walking

The records for walking vary considerably; most of the men averaged not far from 3 to 4 hours. In striking contrast to this are, however, the values for Gul of 7 hours, Mon of 7 1/2 hours, and Pea of 9 hours. Although every effort was made to secure as accurate and objective records for these men as possible, it is clear that errors - indeed, serious errors - crept into these estimates, for an examination of the pedometer records for Squad A from January 14 to February 2 shows that while the correlation between the number of hours estimated for walking and the miles recorded on the pedometer is reasonably constant with most of the men, we have several wide differences.

Thus Gul reported an average of 7 hours per day walking, while the pedometer showed but 10 miles. Mon reported 7 1/2 hours with a mile-age of 5.8 miles. Pea with 9 hours, the highest record, showed a pedometer reading of but 6.2 miles. On the other hand, we have the extremely small value of 2.25 hours with Pec, and a pedometer record of 8.3 miles. Under the circumstances a strict comparison of either pedometer records or activity records must be made with great reserve.

1A recent operation prevented Tom from engaging in strenuous exercise and called for a larger percentage of hours sitting. "Endurance test" and motion pictures on Feb. 1.

2Gymnasium work and snow-shoeing; 25 mins. riding bicycle ergometer; "endurance test"; motion pictures.

Exercise Greater Than Walking

It is particularly unfortunate that we have to rely to so large an extent upon conjecture for this degree of activity. It is clear that in a number of instances the men reported under the head of walking quite a variety of activities which should have been reported as greater than walking, and vice versa. According to the records the exercise more strenuous than walking is for all the men somewhat light, i. e., 1 to 2 hours on the average, although we have the excessive amount attributed to Gul of 4 3/4 hours. An admittedly unsatisfactory attempt is made to indicate in a general way the character of the exercise greater than walking; this is shown by the footnotes below the data for each subject. It can be seen that gym-nasium work in various forms plays, as is to be expected, rather an important r61e. The work on the bicycle ergometer is not shown in the individual records but is given in the footnotes and taken account of in computing the average per day.
