Success in Athletics and how to obtain it

194 SUCCESS IN ATHLETICS however, may vary slightly, according to the direction of the wind. If one is throwing with the wind, a some– what higher trajectory may be given to the weapon. It is a curious fact, and worthy of note, that the javelin invariably flies better, and with greater steadi- c t • a Diagram 35· ness, if not as far, when one is throwing against the wind as when one is throwing with it. In throwing the javelin, the whole result, from a dynamical point of view, hinges on two main points– viz. the strength of the thrower and a perfect balance. On inquiring into the question of errors which arise in throwing, the factor of strength does not concern us, as it must be assumed for the minute that the thrower is one of average strength. The only way in which it may be considered at the present moment is that the stronger the man is, and the more his strength is applied to an incorrect balance, the greater .will be the resulting error. If this statement · is borne in mind, it will perhaps become m0re apparent as the question of balance is dealt with ; therefore, let us deal straight away with this point, as it is undoubtedly the most important one, and the one which governs the perfect throw. Balance, of course, is "centre of gravity." A body will be in "stable equilibrium " when it is so suspended that a slight swing to either side will cause it to gently oscillate until it comes to rest again with its centre of gravity vertically under the point of suspension. :l
