Youth: Its Education, Regimen, and Hygiene 5

Youth: Its Education, Regimen, and Hygiene 5


With these facts and their implications in mind we can next pass to
consider the conditions under which the adolescent muscles best
develop. Here we confront one of the greatest and most difficult
problems of our age. Changes in modern motor life have been so vast
and sudden as to present some of the most comprehensive and
all-conditioning dangers that threaten civilized races. Not only have
the forms of labor been radically changed within a generation or two,
but the basal activities that shaped the body of primitive man have
been suddenly swept away by the new methods of modern industry. Even
popular sports, games, and recreations, so abundant in the early life
of all progressive peoples, have been reduced and transformed; and the
play age, that once extended on to middle life and often old age, has
been restricted. Sedentary life in schools and offices, as we have
seen, is reducing the vigor and size of our lower limbs. Our industry
is no longer under hygienic conditions; and instead of being out of
doors, in the country, or of highly diversified kinds, it is now
specialized, monotonous, carried on in closed spaces, bad air, and
perhaps poor light, especially in cities. The diseases and arrest bred
in the young by life in shops, offices, factories, and schools
increase. Work is rigidly bound to fixed hours, uniform standards,
stints and piece-products; and instead of a finished article, each
individual now achieves a part of a single process and knows little of
those that precede or follow. Machinery has relieved the large basal
muscles and laid more stress upon fine and exact movements that
involve nerve strain. The coarser forms of work that involve hard
lifting, carrying, digging, etc., are themselves specialized, and
skilled labor requires more and more brain-work. It has been estimated
that "the diminution of manual labor required to do a given quantity
of work in 1884 as compared with 1870 is no less than 70 per
cent."[11] Personal interest in and the old native sense of
responsibility for results, ownership and use of the finished
products, which have been the inspiration and soul of work in all the
past, are in more and more fields gone. Those who realize how small a
proportion of the young male population train or even engage in
amateur sports with zest and regularity, how very few and picked men
strive for records, and how immediate and amazing are the results of
judicious training, can best understand how far below his
possibilities as a motor being the average modern man goes through
life, and how far short in this respect he falls from fulfilling
nature's design for him.
 
For unnumbered generations primitive man in the nomad age wandered,
made perhaps annual migrations, and bore heavy burdens, while we ride
relatively unencumbered. He tilled the reluctant soil, digging with
rude implements where we use machines of many man-power. In the stone,
iron, and bronze age, he shaped stone and metals, and wrought with
infinite pains and effort, products that we buy without even knowledge
of the processes by which they are made. As hunter he followed game,
which, when found, he chased, fought, and overcame in a struggle
perhaps desperate, while we shoot it at a distance with little risk or
effort. In warfare he fought hand to hand and eye to eye, while we
kill "with as much black powder as can be put in a woman's thimble."
He caught and domesticated scores of species of wild animals and
taught them to serve him; fished with patience and skill that
compensated his crude tools, weapons, implements, and tackle; danced
to exhaustion in the service of his gods or in memory of his forebears
imitating every animal, rehearsing all his own activities in mimic
form to the point of exhaustion, while we move through a few figures
in closed spaces. He dressed hides, wove baskets which we can not
reproduce, and fabrics which we only poorly imitate by machinery, made
pottery which set our fashions, played games that invigorated body and
soul. His courtship was with feats of prowess and skill, and meant
physical effort and endurance.
 
Adolescent girls, especially in the middle classes, in upper grammar
and high school grades, during the golden age for nascent muscular
development, suffer perhaps most of all in this respect. Grave as are
the evils of child labor, I believe far more pubescents in this
country now suffer from too little than from too much physical
exercise, while most who suffer from work do so because it is too
uniform, one-sided, accessory, or performed under unwholesome
conditions, and not because it is excessive in amount. Modern industry
has thus largely ceased to be a means of physical development and
needs to be offset by compensating modes of activity. Many
labor-saving devices increase neural strain, so that one of the
problems of our time is how to preserve and restore nerve energy.
Under present industrial systems this must grow worse and not better
in the future. Healthy natural industries will be less and less open
to the young. This is the new situation that now confronts those
concerned for motor education, if they would only make good what is
lost.
 
Some of the results of these conditions are seen in average
measurements of dimensions, proportions, strength, skill, and control.
Despite the excellence of the few, the testimony of those most
familiar with the bodies of children and adults, and their physical
powers, gives evidence of the ravages of modern modes of life that,
without a wide-spread motor revival, can bode only degeneration for
our nation and our race. The number of common things that can not be
done at all; the large proportion of our youth who must be exempted
from any kinds of activity or a great amount of any; the thin limbs,
collapsed shoulders or chests, the bilateral asymmetry, weak hearts,
lungs, eyes, puny and bad muddy or pallid complexions, tired ways,
automatism, dyspeptic stomachs, the effects of youthful error or of
impoverished heredity, delicate and tender nurture, often, alas, only
too necessary, show the lamentable and cumulative effects of long
neglect of the motor abilities, the most educable of all man's powers,
and perhaps the most important for his well-being. If the unfaithful
stewards of these puny and shameful bodies had again, as in Sparta, to
strip and stand before stern judges and render them account, and be
smitten with a conviction of their weakness, guilty deformity, and
arrest of growth; if they were brought to realize how they are fallen
beings, as weak as stern theologians once deemed them depraved, and
how great their need of physical salvation, we might hope again for a
physical renaissance. Such a rebirth the world has seen but twice or
perhaps thrice, and each was followed by the two or three of the
brightest culture periods of history, and formed an epoch in the
advancement of the kingdom of man. A vast body of evidence could be
collected from the writings of anthropologists showing how superior
unspoiled savages are to civilized man in correct or esthetic
proportions of body, in many forms of endurance of fatigue, hardship,
and power to bear exposure, in the development and preservation of
teeth and hair, in keenness of senses, absence of deformities, as well
as immunity to many of our diseases. Their women are stronger and bear
hardship and exposure, monthly periods and childbirth, better.
Civilization is so hard on the body that some have called it a
disease, despite the arts that keep puny bodies alive to a greater
average age, and our greater protection from contagious and germ
diseases.
 
The progressive realization of these tendencies has prompted most of
the best recent and great changes motor-ward in education and also in
personal regimen. Health- and strength-giving agencies have put to
school the large motor areas of the brain, so long neglected, and have
vastly enlarged their scope. Thousands of youth are now inspired with
new enthusiasm for physical development; and new institutions of many
kinds and grades have arisen, with a voluminous literature, unnumbered
specialists, specialties, new apparatus, tests, movements, methods,
and theories; and the press, the public, and the church are awakened
to a fresh interest in the body and its powers. All this is
magnificent, but sadly inadequate to cope with the new needs and
dangers, which are vastly greater.

[Footnote 9: Dr. Hughlings Jackson, the eminent English pathologist,
was the first to make practical application of the evolutionary theory
of the nervous system to the diagnosis and treatment of epilepsies and
mental diseases. The practical success of this application was so
great that the Hughlings-Jackson "three-level theory" is now the
established basis of English diagnosis. He conceived the nervous
mechanism as composed of three systems, arranged in the form of a
hierarchy, the higher including the lower, and yet each having a
certain degree of independence. The first level represents the type of
simplest reflex and involuntary movement and is localized in the gray
matter of the spinal cord, medulla, and pons. The second, or middle
level, comprises those structures which receive sensory impulses from
the cells of the lowest level instead of directly from the periphery
or the non-nervous tissues. The motor cells of this middle level also
discharge into the motor mechanisms of the lowest level. Jackson
located these middle level structures in the cortex of the central
convolutions, the basal ganglia and the centers of the special senses
in the cortex. The highest level bears the same relation to the middle
level that it bears to the lowest i.e., no continuous connection
between the highest and the lowest is assumed; the structures of the
middle level mediate between them as a system of relays. According to
this hierarchical arrangement of the nervous system, the lowest level
which is the simplest and oldest "contains the mechanism for the
simple fundamental movements in reflexes and involuntary reactions.
The second level regroups these simple movements by combinations and
associations of cortical structure in wider, more complex mechanisms,
producing a higher class of movements. The highest level unifies the
whole nervous system and, according to Jackson, is the anatomical basis of mind."
