AquaTrainer® Snorkel does not Increase Hydrodynamic Drag but Influences Turning Time

A new study on the aquatrainer was published on the International Journal of Sport Medicine on the new Aquatrainer snorkel option.

This study purpose was to verify if the use of the new AquaTrainer® respiratory snorkel lead to an increase of front crawl hydrodynamic drag and whether the constraint of using an adapted turning technique influences its corresponding turning time.

The study concludes that "AquaTrainer® snorkel does not lead to an increase in active drag during front crawl performed at a large range of velocities and, consequently, the metabolic energy necessary to overcome total drag will not be affected. However, turning with it requires an additional time that should be taken into account in scientific research and training conditions.".
