A Riemannian affine connection on a Riemannian manifold has the property that is preserves the ``kinetic energy'' associated with the metric. However, there are other affine connections which have this property, and here we characterise them. A class of such energy-preserving affine connections, related to mechanical systems with constraints, is provided.
