Sorry, the last guy I knew who knew those facts and where to look up the historical sources for them was back in college. I could only say it would be the wrestling and sword-fighting arts practiced on the Arabian Peninsula back in the 600s. The only other guy I've heard mention it since then is a famous Greek Orthodox convert to Islam named Hamza Yusuf who the second President Bush made his consultant on Islam and Muslims back when he was President. He has like hundreds of speeches out on CD on different aspects of Islam, and I heard it on one of his CDs (I don't remember which one). Since he's famous, I don't know if he'd respond if I contacted him, or if I could even find any contact information for him...
I was on the metro earlier, deep in meditation, when a ruffian came over and started causing trouble. He started pushing me with his bag, steadily increasing the force until it became very annoying. When I turned to him, before I could ask him to stop, he immediately started hurling abuse like a scoundrel. I performed a basic chin na - carotid artery strike combination and sent him to sleep. The rest of my journey was very peaceful, and passersby hailed me as a hero - Warrior Man
