Episode 19 of #biomechtalk What is moment of inertia?

Moment of inertia is a concept I usually struggle to wrap my head around. But hopefully this gif helps it stick in your brain a bit more 😂😬

Moment of inertia is a measure of resistance to changes in rotational motion of an object (or a body because we care about sports biomechanics). Athletes and coaches should care about this concept because an athletes body position in the air can change their moment of inertia.

For example in gymnastics, a back tuck would have a smaller moment of inertia than a back layout. High moment of inertia, harder to rotate and more force needs to be applied to cause this rotation. This applies in many more examples too, think diving, snowboarding, cheerleading, and jumping! Thought this would be a good way to ring in fall 🍂🍁 (ok I’m done bye 😂)
