It should be begun very gradually at the opening of the skating season, and not undertaken if the internal organs are prolapsed.
Rowing.
Rowing is an exercise that develops the upper back and back of shoulders, and therefore needs to be counteracted by exercise that calls into play the muscles of the front of the chest.
Cycling.
The dangers of cycling arise principally from lack of judgment. The temptation to overdo is very great, and injury is done in attempts to ride longer, farther and faster than the strength will safely allow. The whole dress should be so arranged as to give perfect freedom of movement, the skirt short enough to clear the dangerous part of the mechanism, the saddle adjusted to the individual both in its make and height, and the girl be taught to sit properly and to adjust her weight so that the pressure will not be undue upon the perineum. Rectal and other local irritations are produced by the pressure of the whole weight resting on the saddle.
The position should not be absolutely erect, but leaning slightly forward, so as to allow the weight to be distributed between the handle-bars, the pedal, and the saddle. This slightly inclined attitude also maintains the proper and harmonious relation of the internal organs, so that the bowels do not crowd down on the pelvic organs.
If the girl is taught to sit on the machine properly, to distribute her weight, to sit on the large gluteal muscles, and not on the perineum, to use judgment in the amount of exercise taken at a time, there is no reason why a girl in a normal condition of health should not be benefited.
There may be particular reasons why some girls should not undertake to ride, and these can be determined by the physician.
