The Hidden Cost of a Loaded Belt
What does the science of biomechanics actually say about carrying a heavy tool belt, duty belt, or EDC setup? This episode traces the field back to its World War II origins at the Harvard Fatigue Laboratory, then walks through the physics of walking—the inverted pendulum model of gait—and what happens when you add asymmetric weight to your hips. We look at a landmark 1995 Army Natick study showing 12% higher oxygen consumption and 18% more lateral trunk displacement for hip-carried loads, and a 2018 Applied Ergonomics study finding that police officers carrying 8-12 pound duty belts had 2.3…
