Type A sensors measure hand force

Feedback is instantaneous

Aquanex analyzes all four competitive swimming strokes: freestyle, breaststroke, backstroke, and butterfly. The sensors stay in place between the third and fourth fingers so the swimmer can use his/her normal technique. It takes less than a minute to outfit a swimmer with Aquanex sensors. Immediately after the test trial, the video and force data is displayed on the computer. A frame by frame playback of the video moves a cursor along the force curves to show the amount of hand force.

Aquanex provides a complete quantitative analysis -

• Hand force fluctuations within each stroke cycle

• Stroke rate and stroke length

• Peak force and average force

• Pull time and recovery time

• Swimming velocity

Aquanex is an appropriate diagnostic tool for all levels of competitive swimmers - age-groupers through Olympians. Aquanex provides extensive data about a swimmer's technique - positive elements, as well as factors that limit performance. Faster, more competitive swimmers generally have less obvious limiting factors in their technique. Aquanex is essential for these swimmers, because a video analysis alone will not show how changes in hand motion cause a loss in force.

Does your force curve look like this?

This curve shows a fast and steady increase in force, characteristic of effectively using strength throughout the entire stroke cycle.

Or does your force curve look like this?

This curve shows a major force loss, characteristic of a sudden change in hand path, pitch, or speed.
