ABSTRACT
The athletics have been grouped by Kretschmer under the schizo-temperament group. Later researches have indicated that not only on clinical grounds are there intimate relations between leptosomes and athletics, but also on experimental psychological grounds. Enke has shown that in the persistence of intentions, endurance of tensions, e.g. in consistent regular pressure on the pen in writing, forethought in the suspicion test, etc., the athletics and leptosomes differ widely from the pyknics. 1 Van der Horst’s experiments gave more or less the same results. 2
