Swimming in a wetsuit differs from training in a bathing suit in a few important ways, including body position. The added buoyancy that comes with wearing a wetsuit lifts the body into an unnaturally horizontal (and efficient) position in the water, subtly affecting stroke mechanics and reducing resistance. To simulate those changes in training, Zone 3 created the Neoprene Buoyancy Shorts (Roka makes a similar product) that prop the body into a position similar to swimming in a wetsuit.
Payoff: Training in these shorts reduces resistance slightly, and helped the tester get accustomed to a faster stroke rate without compromising stroke power.
