HEART DISEASES: DIAGNOSIS – TRAINING

To develop full co-ordination between heart action, breathing and muscular effort, it is necessary to undergo training of a broad and prolonged nature. With youngsters, this is attempted in the physical education given in schools, but rarely reaches the required standards. True efficiency and harmony in the workings of eye, ear, balance, judgment and muscular control cannot be attained by brief and specialized effort — however intense.

Their tremendous capacity for producing energy, and their great recuperative powers, often mask the true state of affairs in young people. Their training may be both imperfect and productive of great temporary distress in the heart, yet lead to good performance and no permanent harm. The fact of their being in any kind of training diminishes the risk of serious injury, provided that thtir tissues are in a reasonably wholesome state. Even what may appear to be excessive exertion need not, in such conditions, cause any lasting cardiac disorder. The situation is quite different if the individual has had no training in the way of physical exertion, or if his vital level has been depressed by wrong treatment — such as a spell of 'feeding to keep up his strength' during any feverish illness. A comparable effort, or even a much more modest attempt, by an untrained person of sedentary occupation or by one suffering from such incorrect treatment, may produce acute cardiac disease and lead to years of invalidism.
