Ever wondered how far the average person could actually run before their body gives out? In this vídeo we break down the real physiology behind endurance: how your running performance depends on glycogen, fat burning, hydration, and what happens when dehydration, overheating, rhabdomyolysis or even organ failure start to kick in. We explore the true limits of the human body under extreme effort, why collapse happens, and how pushing too far turns a simple run into a life-threatening scenario. If you’re curious about endurance, limits, and what really happens inside your body when you keep running without stopping, this is your vídeo. ✨ About Science Pops ✨ Science Pops brings you fun, clear, and engaging videos about the hidden science of the human body, the brain, everyday habits, and fascinating curiosities.
