Hand paddle

[1] This gives the swimmer considerably more forward propulsion from the arm stroke than does a naked hand, and affords an enhanced kinesthetic "feel" of the pull.

[1] If the hand catches or pulls at an incorrect angle, the increased resistance afforded by the hand paddle will exacerbate the resultant twisting moment, making the defect clearer to the swimmer.

[2] The considerably increased load imposed by the hand paddle on the arm and shoulder can, however, lead to pain and an increased risk of injury, so coaches advise only limited use of paddles and that use be discontinued if the swimmer feels shoulder pain.

[2][3] To make the most out of using paddles, it is important to ensure that they aid in establishing a good technique under the water.

[citation needed] The hand paddle was invented by Benjamin Franklin in the 18th century.
