Oshchepkov without hesitation threw away many "antiquarian treasures" of judo and resolutely renewed techniques. Obsolete methods were replaced by new effective ones.
Enrichment and developing techniques by different ways was one of the main task of Vasilii Sergeevich. First, he include joint locks on the legs, absent in sport judo. Also, it was used training-competition practice of various Oshepkov's students and himself's one. It developed new features in this enrichment "manner of performing the methods". This practice was received in new, different from classical judo, conditions, and followed by new independent methods and combinations. All this things gave results, but decisive factor was not here.
Oshchepkov analysed all existed international kinds of wrestling, chinese wushu, and a number of national kinds of wrestling from the "application in real fighting" point of view. He was concentrated not only on strikes from wushu, english and french boxing, but also on the methods from "finnish-french" wrestling and some other kinds of wrestling, which Vasilii Sergeevich named "free-style": american free-style wrestling, swiss wrestling, caucasian wrestling and persian wrestling. He specially noted that some methods and, especially, throws, could be applicable as self-defence methods.
