This article investigates the effects of swimming eyewear on speed. Many triathletes use the Aqua-Sphere mask because it makes them feel more comfortable in the water. Conversely, many competitive swimmers wear Swedish goggles and have done so for decades. But, how much of a difference does goggle choice really make? It may seem like Swedes should be a clear winner because of their smaller size. However, it could also be that an Aqua-Sphere could allow faster times because it traps air under the surface that could add to buoyancy.

Q: What is the purpose for hypoxic (breath holding) training for swimmers and triathletes?

A: Before I respond, I must warn that holding your breath for extended periods in the water is a dangerous activity.  Don’t do it unless you know what you are doing.  And do make sure a qualified and trained individual is watching you from the deck, like a lifeguard or coach.  Also, check with the facility as many places will not let you practice breath holding training.  Stop immediately if you feel sick, dizzy or light-headed.  Passing out in the middle of the pool is always a bad moment.
