MUSCULAR WORK 
It seems evident, therefore, that it will be more desirable to present the 
data as a whole first and then draw from the average figures such deductions 
as are permissible. Accordingly, in table 92, are presented the average quo- 
tients found before, during, and after work. Such quotients as were obtained 
in later periods will be found in the footnotes. No indication is given in the 
table as to how many periods are included in the averages nor of the actual 
amount of work done, since the data are intended to present only a general 
picture of the results."

1 The work-periods on this day were begun about 1 f hours after the conclusion of the periods lying before 
work. The subject rode without load and without motor for li hours in the interval. 
2 Only one period lying before work was run on this day. 
3 The respiratory quotient during the third hour lying after work was 0.80; during the fourth hour, 0.77; and 
during the fifth hour, 0.80. 
* The respiratory quotient during the third hour lying after work was 0.79. Another work-period followed 
for which the respiratory quotient was 0.81. In the three-quarters of an hour subsequent to this last 
work-period, the average respiratory quotient was 0.77 with the subject lying on the couch. 
6 The work-periods on this day were begun about 2 J hours after the conclusion of the periods lying before work. 
During the interval the subject sat inactive on the ergometer for two periods; he then rode for about 
1 hour without load on the motor-driven ergometer. 
6 Other work-periods were then run for which the average respiratory quotient was 0.90. In the half-hour 
following the latter work-periods, the respiratory quotient was 0.81 with the subject lying on the couch. 
1 Other work-periods were then run for which the average respiratory quotient was 0.94. In the three- 
quarters of an hour following the latter work-periods, the average respiratory quotient was 0.95 with 
the subject lying on the couch. 
8 Other work-periods were then run for which the average respiratory quotient was 0.93. In the three-quar- 
ters of an hour following the latter work-periods, the average respiratory quotient was 0.88 with the 
subject lying on the couch. 
9 Other work-periods were then run for which the average respiratory quotient was 0.87. In the 45 minutes 
following the latter work-periods, the average respiratory quotient was 0.74 with the subject lying on 
the couch. 
10 The respiratory quotient during the third hour lying after work was 0.82; during the fourth hour, 0.79; 
during the fifth hour, 0.75; and during the sixth hour, 0.81. 
In order to bring out in the sharpest contrast the relationships of the 
periods before work, during work, and after work, two separate averages 
The data are given in greater detail in tables 93 and 136.
