The measure of an individual's ability to perform complex activities requiring a high level of co-ordination between mind and body is called "perceptual-motor accuracy" or motor skills.

In a study by Dr Peter Suedfeld (University of British Columbia, Vancouver), recreational basketball players - tested one day before and one day after a single session of floatation plus visualization - showed an astonishing mean improvement of 37% in free-throw success compared to control groups.

Suedfeld followed this up with a study of recreational darts players' ability to throw "bull's-eyes". The subjects - tested immediately before and immediately after a single session of floatation plus visualization - showed an impressive 13% improvement in accuracy compared to control groups.
·
Interestingly, another of the test groups in Suedfeld's dart-throwing study - one assigned to floatation without any visualization exercise - showed an 11% improvement.

REST researchers have documented the effect of floatation in improving motor skills across a wide range of activities: basketball throws, rifle shooting, bowling, tennis, gymnastics, dart-throwing, and even performance in a flight simulator.
