Chanko Crushes Aggressive Spar Partner

Islam Makhachev has a training partner who went viral for being called John Pork. His real name is Chanko. Here, we see him drop his spar partner with a perfectly timed knee. Thank you for joining me on this educational breakdown as we take a closer glance. More: A knee to the body (especially to the liver, solar plexus, or floating ribs) can instantly knock someone out or drop them even if it doesn't hit the head. Here's why in simple terms:Massive pain shock + vagus nerve response: A clean knee to the liver (left side of the body) causes excruciating pain that overwhelms the nervous system. The vagus nerve gets stimulated, triggering a sudden drop in heart rate and blood pressure — this is called a vasovagal response. The brain basically gets starved of oxygen for a few seconds and the person collapses, sometimes completely unconscious. Solar plexus (center of chest/stomach) impact: The knee compresses the diaphragm and hits the celiac plexus (a huge bundle of nerves). This paralyzes the diaphragm temporarily — you literally can't breathe. The combination of "wind knocked out" + intense nerve shock makes the brain shut the body down as a protective mechanism. People often go stiff and fall like a tree. Trauma to organs + rapid pressure change: The force can temporarily disrupt organ function and cause a sudden spike/dip in intra-abdominal pressure, again leading to that same vasovagal knockout. Famous examples: Bas Rutten’s liver shots, Wanderlei Silva’s knees in Pride, or Thiago Santos dropping Jan Błachowicz with a body knee. It looks like a head kick KO but the person is actually got "turned off" by the body shot. It’s one of the most brutal and instant ways to end a fight without touching the head.
