PART II. 
STATISTICS OF EXPERIMENTS. 
In this series of experiments, 7 subjects were used. The statistics as to 
their occupation, age, height, and average weight without clothing are given 
in table 5. With the single exception of M. A. M., none of the subjects had 
any special training in bicycle riding or had ever ridden to excess, nor did 
any of them own bicycles; for many months previous to the experiments, 
they had ridden only intermittently, if at all.

The subject M. A. M., with whom most of the experiments were made, 
began riding as an amateur in 1896 and as a professional bicyclist in 1901, 
continuing until 1910. Between 1901 and 1905 he took part in 5 motor-paced 
races; in 1905 he rode in a 6-day bicycle race in New York City and in a 
second in 1907. He also rode in numerous smaller races and kept in general 
good condition up to the time of the beginning of the experiments. While the 
subject never took a regular training course, he exercised regularly in a 
gymnasium between 1896 and 1908, and practiced boxing considerably, 
although with no special success. As in 1907 his nose was broken, the boxing 
practice was discontinued. His maximum weight previous to the research 
was in May 1911, when he weighed 66.7 kilograms. During the research 
he was twice examined physically by Dr. W. G. Anderson, of Yale University. 
As a result of the examination on March 4, 1912, Dr. Anderson said that the 
subject was remarkably well developed, particularly in the abdominal and 
thigh muscles, but drew attention to the somewhat surprising fact that the 
lower leg-muscles, particularly the gastrocnemii, were not well developed. 
A second examination was made by Dr. Anderson on April 25, 1912, the re- 
sults of which are given in table 6. Information regarding the dietary habits 
of the subject is given on page 80. 
In presenting the statistics of the experiments, we have grouped them 
under three heads: (1) lying vs. sitting experiments; (2) no-load experiments 
both with and without motor; (3) work experiments. The general character 
of each class of experiments has been described in some detail on pages 31 
and 32. In these groups, the experiments have been arranged first according 
to subject and then for the most part chronologically. Reference to the 
statistical details of any experiments may thus be readily made.
