The sense of how to shift our position on a playground swing tends to come naturally as part of growing up – a bit like learning how to ride a bike – and now scientists have put together a mathematical model for the ultimate swinging technique.
In particular, the model identifies how riders adapt how they 'pump' the swing as the swinging distance increases. Until now, the perfect swinging technique hasn't been put down in scientific form.
As the swinging motion builds momentum, you need to start leaning back earlier – ideally at the highest point on the backward swing, just before you start going forward again. It's this change that maximizes the oscillations of the swing. , where riders rock backward and forward at a fixed frequency, creating a sort of sine wave with their bodies. It's fine at the start, but it doesn't really work as the swinging distance starts to increase. was also considered. This proposes that people shift their weight automatically based distance of each swinging motion and their point in it, but there are issues with this model.
Sure enough, motion capture data revealed that study participants were indeed pumping the swing as predicted by the new and improved mathematical model, a combination of the FFM and the SWM.
