Drag force ?
- "Drag force" .
, . .
Propulsion through the water in swimming occurs from both lift forces and drag forces. Drag forces are always opposite to the direction of force application, so if the hand pushes the water backward the drag forces act to propel the body forward.

Propulsion through the water in swimming occurs from both lift forces and drag forces. Drag forces are always opposite to the direction of force application, so if the hand pushes the water backward the drag forces act to propel the body forward (Kreighbaum and Barthels 1996). This is the principle used in using a paddle to propel a canoe- the paddle pushes the water backward and the reaction force from the water pushes the canoe forward. Drag forces occur as the athlete pushes down on the water, the water pushes back up on the athlete helping in support.
