Abstract
The results of our experiments, consisting of putting a 5 kg shot after brief exposures to loads of various intensities (3 kg, 5 kg and 7 kg shots), confirmed the findings of Bujas and Petz whose research was carried on in static work. The distance, to which the standard 5 kg shot was put, was 7.3 cm longer when the "warming up" consisted of previous throws of the 7 kg shot, than when it consisted of previous throws of the 3 kg shot. These differences are statistically highly significant. On the basis of the obtained results, it seems probable that different mechanisms of "warming up" are operative in intensive "warming up", where the mechanism is probably of a central nature, and in a "warming up" of low intensity, where it is probably of a peripheral nature. From these results it would seem, as Bujas and Petz already pointed out, that, other things being equal, an intensive "warming up" of short duration is more efficient than a "warming up" of low intensity.
