Physiological economy in nutrition, with special reference to the minimal proteid requirement of the healthy man: an experimental study
Chittenden, R. H. (Russell Henry)
Metabolism; Nutrition
The men were not above the average standard, physically, when
they began their work, this standard being set by applicants
for firemen and policemen, not by college students. At the end
of their training they were much above the same standard, while
their strength tests were far greater than the averages made by
college men. They showed less improvement in increase in size
than University men do under like gymnastic treatment, but the
gain in self-confidence and in body-fibre was very evident. The
gain in accuracy and skill was marked. The men showed interest
in their work throughout the six months. At the end of the
period of training the soldiers were in excellent condition in
spite of the fact that in some cases there was a slight loss of
body-weight. This loss is not to be attributed necessarily to
the diet, because most men who exercise lose slightly if there
is an excess of adipose tissue.
Respectfully yours,

Dr. Anderson furnishes the following “Notes” descriptive of the methods
by which the strength tests were made:
“_Strength of Back._ The subject, standing upon the iron foot-rest with
the dynamometer so arranged that when grasping the handles with both
hands his body will be inclined forward at an angle of 60 degrees, should
take a full breath and, without bending the knees, give one hard lift,
mostly with the back.
“_Strength of Legs._ The subject while standing on the foot-rest with
body and head erect, and chest thrown forward, should sink down, by
bending the knees, until the handle grasped rests against the thighs,
then taking a full breath, he should lift hard principally with the legs,
using the hands to hold the handle in place.
“_Strength of Chest._ The subject with his elbows extended at the
sides until the forearms are on the same horizontal plane and holding
the dynamometer so that the dial will face outward and the indicator
point upward, should take a full breath and push vigorously against the
handles, allowing the back of the instrument to press on the chest.
“_Strength of Upper Arms, Triceps._ The subject, while holding the
position of rest upon the parallel bars, supporting his weight with arms
straight, should let the body down until the chin is level with the bars,
and then push it up again until the arms are fully extended. Note the
number of times that he can lift himself in this manner.
“_Strength of Upper Arms, Biceps._ The subject should grasp a horizontal
bar or pair of rings and hang with the feet clear from the floor while
the arms are extended. Note the number of times that he can haul his body
up until his chin touches the bar or ring.
