Running is both useful and natural; it favours the development of the chest, dilates the lungs, and, when moderate, is a highly salutary exercise. To run fast and gracefully one should as it were graze the ground with the feet, by keeping the legs as straight as possible whilst moving them forward. During the course the upper part of the body is inclined a little forward, the arms are as it were glued to the sides, and turned in at the point of the hips, the hands shut, and the nails turned inwards. The faults in running are swinging the arms, raising the legs too high behind, taking too large strides, bending the knees too much, and in not properly managing their wind. In all running exercises the young should begin gradually, and never run themselves out of breath at any time. By careful practice a boy may soon acquire the power of running a mile in ten minutes; this is called moderate running: in what is called prompt running a thousand yards in two minutes is thought very good work, and in quick running 600 yards in a minute is considered good. The first distance that children, from eight to ten years of age, may be made to run is about 200 yards; the second, for those more advanced, 300 yards; and the third, for adults, 400 yards. It is however most essential, that in running boys should not over-tax their strength or “wind.” We are not all constituted alike, and a boy who could last for 200 yards or so might injure himself considerably by racing for a mile.
JUMPING.
Of all the corporeal exercises jumping is one of the most useful; and during our lives very many instances occur of a good jump having done us essential service. To jump with grace and assurance one should always fall on the toes, taking care especially to bend the knees on the hips: the upper part of the body should be inclined forwards, and the arms extended towards the ground. The hands should serve to break the fall when jumping from a great height. In jumping we should hold the breath and never alight on the heels. Boys should exercise themselves in jumping, by jumping in length, and jumping from a height, with attention to the above cautions. They may make progressive exercises in length by varying the distance from time to time, and in height by jumping from a flight of stairs or steps, increasing a step at a time: they will soon be able to jump in length three yards, and from a height six feet, without injury.
LEAPING.
Leaping is somewhat different to what is called jumping, as the object is to pass over an obstacle; and, as in jumping, it is of great importance to draw in the breath, while the hands should be shut, the arms pendent, to operate after the manner of a fly-wheel or pendulum. It may be practised by a leaping stand, which can be easily made of two sticks or stakes sunk in the ground, in which little catches are made at various distances, on which an even piece may be laid, that may readily be knocked over, so as to offer no resistance to the jumper, and injure him by an ugly fall.
The principal exercises in leaping are:—1. The high leap without a run. 2. The high leap with a run. 3. The long leap without a run. 4. And the long leap with a run. In the first of these the legs and feet are closed, the knees are bent till the calves nearly touch the thighs, and the arms are thrown in the direction of the leap, which increases the impulse. This leap may be practised at the following progressive heights,—eighteen inches, twenty-four inches, thirty-two inches, forty-eight inches, which last is perhaps what few lads would attain.
The high leap with a run.—The run should never exceed twelve paces, the distance between the point of springing and the obstacle to leap over to be about three-fifths the height of the obstacle from the ground; and in making it the leaper should go fairly and straightly over without veering to the side, and descend on the ball of the foot just beyond the toes. The heights that may be cleared by the running leap vary from three to six feet. A good leaper of sixteen years old ought to leap four feet six inches, and an extraordinarily good leaper five feet. Adults well trained will leap six, and some have been known to leap seven feet.
The long leap without a run.—The long leap may be marked out from four to eight feet, according to the agility and strength of the leaper; and the object to be cleared, a small block of wood, which should in this kind of leap be never more than six inches high, placed midway. In leaping the body is bent forward, the feet are closed, the arms first sway forwards, then backwards, and then forwards at the moment of taking the leap. In this kind of leap ten or twelve feet is considered good work.
The long leap with a run.—The run should be on firm level ground. The body should be inclined forward, and the run consist of about twelve paces, a small block of wood, as before, being placed mid distance in the leap. The spring should be principally on the right foot, and the arms should be thrown forwards at the time of the leap. In descending, if the leap be a very long one, the leaper should descend principally upon his toes; if the leap be not very long, he may descend on the balls of the toes. The leap is considered good if fifteen feet be cleared, but twenty may be done by a good leaper, and one or two individuals have fairly reached twenty-three feet.
