Oar
A shafted lever with a blade at one end used to propel a rowing boat, pivoting against the boat at a rowlock rather than being held free like a paddle.
Definition
An oar is the long lever a rower uses to move a boat, with a shaped blade at the water end and a handle at the other. Crucially, an oar pivots against the boat at a rowlock or gate, which acts as a fulcrum, so the rower drives the boat forward by levering the blade through the water.
In sweep rowing each rower handles a single oar with both hands, while in sculling each rower uses two shorter oars, called sculls, one in each hand. This attachment to the boat is what separates an oar from a paddle, which is held free and used in canoeing and kayaking.

Sports science
- Managing fatigue and loadThe educational idea of balancing how much training you do against how well you recover, so effort turns into progress rather than into excess fatigue.
- The overload principleThe idea that the body adapts to demands greater than it is used to — the foundation of why training works.
- Recovery and adaptationThe idea that the body adapts during recovery, not during the effort itself — which is why rest is treated as part of training rather than a break from it.
