In this episode of Weslee Weighs In, we get the medical perspective on some of jiu-jitsu’s biggest injury risks, including heel hooks, reaping, guard jumping, weight cuts, and more.

Dr. Kreiswirth has been on the mats providing medical coverage for jiu-jitsu tournaments since the sport looked very different than it does today. From the early days of tournament medicine to massive multi-day events like Worlds, he’s seen firsthand how the sport, and the way we respond to injuries, has evolved.

Dr. K explains how medical staff evaluate an athlete in seconds, what injuries they see most often, and why some of the most serious-looking injuries aren’t always as catastrophic as they appear on video.

We also get into the issues surrounding youth and Masters competition, the effects of stress and caffeine on athletes, parental pressure, and why understanding your own body and recognizing when you’re in danger may be just as important as the rules themselves.

Plus, Dr. K shares stories from decades of working tournaments, including dislocated jaws, unconscious competitors, serious knee injuries, and the incident that led us to sit down with him in the first place.

If you’re a jiu-jitsu athlete, coach, parent, or just someone who wants to understand the medical side of the sport, this is a conversation you won’t want to miss.
