“Exercise of strength demands the simultaneous action of a great number of muscles.” “Exercise of speed involves repetition of movement and the application of nervous energy.” “Exercises of endurance permit of economy of fatigue,” and are characterized by the necessity of perfect equilibrium between muscular effort and the powers of assimilation of the system.
In exercise of strength, every muscle should bring its whole force into play, and the bony structure is united by pressure to make a rigid whole. “Exercises of speed are accompanied by fatigue out of proportion to the mechanical work represented.” “Every movement needs the intervention of a great number of muscles; each muscle must contract with definite force in order that the whole work may lead to definite movement.”
Co-ordination is the operation of choosing the muscles which shall participate in a certain movement and of regulating the exact quantity of nervous energy necessary to produce the right amount of contraction. Automatism is acquired by practice; and the muscles must be exercised regularly to enable them to respond intuitively. A complicated series of movement can only be acquired gradually, unless the mind has a large number of muscular combinations at command.
“Exhaustion will result from overwork even when well fed.” “Exercises of endurance do not disturb the working of the organs; while increasing their activity, it gives to the system the power to repair wasted tissue, even during work.” Carbonic acid is not formed in excess, and is eliminated without producing noticeable results.
The bicyclist, even though indulging moderately in the pastime, must consider these things, and determine the course to be pursued; otherwise the exercise will prove a bane instead of a blessing. There are principles capable of general or special application; and there are special laws that may be generalized; and all may be made to accord with the exercise of bicycling, but each individual must accept a certain responsibility in the matter. The bicycle having been accepted as a means, the end sought for can be attained only by its intelligent use and application.
One of the many advantages of cycling is that the exercise involved is not limited to the use of any one set of muscles. The legs propel the machine, the muscles of the trunk engage in balancing the body, and the arms are employed in steering and controlling the front wheel. All the larger joints are active, and are made supple as well as strengthened and developed. Muscles, unless directed by mental effort, are useless. The bones give stiffness, and act as levers and fulcrums; the muscles are tools of the mind, levers wherewith to pull and push the bones into position.
Precision of movement means economy of expenditure of force, no more effort being expended than is necessary for the act of the moment. People who hunt for the pedal, and try for the saddle two or three times, and fall off because the bicycle fails to start, work hard enough to have mounted a number of times; that is, they have lifted or supported their own weight in different directions a number of times without attaining their object. They appear to be awkward; they are really unaccustomed to their work. Practice will accustom the muscles to the work they have to do.
Try to do one thing only at a time. If it is mounting, for instance, memorize each thing that must be done; how, when, and where to do it. Do not think, because the mind does not at once grasp all that is forced upon its attention, that your brain is of inferior quality; it may not be able to adapt itself to that particular mental process at that minute. But the effort made will result in added tissue, and next time there will be more hope of success. Increase by a little at a time the amount of exercise undertaken. You can gauge the practice you need only by the amount of attention you give to the subject. After muscles are once trained to an exercise, the mind will not readily lose power to reproduce the combination, and experience begins to help.
Endurance means well-directed strength as well as capacity of power stored in reserve; and the aim of all athletic work is to give an increased store of strength, vitality, and power to draw upon, not merely to expend the stock already on hand.
The muscular development that comes with bicycle exercise will often cause surprise. In persons unaccustomed to active exercise, the increase is most noticeable on the chest and forearms, the chest development increasing two and three inches, the arm and forearm in proportion, and the whole muscular system gaining in firmness and tone. Persistent bicycling, prolonged exercise on the wheel, speed work on the track, develop disproportionately the muscle of the leg. The track-man, therefore, prepares for his season of work, not by exercising and developing his legs, but by general exercise and special work that will develop the arms and back and other sets of muscles not called upon for heavy work during the season when he is to do his best. Getting up speed, increasing speed, and hill-climbing all tend to develop the muscles of the leg, which in such exercise are called upon for the heavy work of push and thrust, using a concentrated power to propel. Light dumbbell work is recommended as a good alternate for bicycle work and a means of keeping the muscular system in balance.
