36 MUSCULAR WORK 
The data for the experiments are given in tabular form and include the 
carbon dioxide eliminated per minute, the oxygen absorbed per minute, the 
respiratory quotient, and the average pulse and respiration rates, the record 
for the respiration-rate usually representing the result of but one observation 
in each period. In the statistics for the no-load experiments, the records of the 
number of revolutions per minute have been added, and in those for the work 
experiments, both the revolutions per minute and the current used through 
the magnetizing field. All necessary details not included in the tabulated 
material are given in footnotes.

The respiratory exchange was determined with a respiration apparatus 
which has already been fully described in the previous section of the report. 
The work was done on a bicycle ergometer; two ergometers were used, 
designated respectively as ergometer I and ergometer II, both of which are 
described on pages 25 to 27. Ergometer I was used in the experiments up to 
January 23, 1912, all subsequent experiments being made with ergometer II. 
The general routine of the experiments is given on pages 31 and 32, 
together with special details as to methods. The subject was without food 
in practically every case, the observations being made in the post-absorptive 
state, i.e., at least 12 hours after the last meal. 
LYING VS. SITTING EXPERIMENTS. 
These experiments were made for the special purpose of obtaining the 
basal metabolism; the statistical details are given in tables 7 to 15 inclusive. 
In the lying experiments, the subject lay as quietly as possible upon a couch, 
no observations being made until the conditions were absolutely normal for a 
rest period. The experiment usually covered three 15-minute periods, with 
intermissions of varying lengths. Lying experiments were made almost every 
day as a part of the regular routine; the statistics for those made in compari- 
son with the no-load and work experiments are given with the statistics under 
these particular heads. 
In the sitting experiments, the subject sat motionless upon the bicycle 
ergometer in position for riding. The general routine as to preliminary periods 
and length was the same as for the lying experiments. As will be seen in 
many of the notes appended to the tables, the subjects found the enforced 
quiet of this position somewhat irksome. An attempt was made with some of 
the subjects to relieve the constraint by supporting the pedals with a block 
of wood, or otherwise, but the experiments with the subject M. A. M. were 
all made without such support.
