Oskar Karl Maria Zoth (28 August 1864, Padua – 30 November 1933, Graz) was an Austrian physiologist.
In 1888 he received his medical doctorate from the University of Graz, where in 1896 he qualified as a lecturer for physiology.
[2] In an 1894 experiment he injected himself with a liquid extraction of bulls' testicles, then tested his muscle strength with a "Mosso ergograph".
In regards to this testing, he stated "the training of athletes offers an opportunity for further research in this area and for a practical assessment of our experimental results".
