It's usually about tiredness causing poor form, which I would think could easily apply to cycling too? Granted fewer chances for something to go wrong but minimising that potential is never a bad thing.
Bikes are kind of unique. When you run, it's very free, but you're much more constrained on a bike. There are three contact points (saddle, pedals, handlebar) and your form is pretty much dictated by how they're arranged. The crank arms keep you turning the pedals over in a circle, always the same size, always in one dimension only. This is why there's so little range of metabolic efficiency among cyclists, because we're all doing almost exactly the same thing. Running economy is a complex thing, but in a way bikes are simpler.
An ill fitting bike can be painful to ride. It won't injure you (unless you crash) but it can cause great soreness. If a bike doesn't fit, this will make itself obvious, then you make it fit.0 -
Sounds to me like you're just out of shape and you need to keep at it, your work capacity will increase.1
