Zone3 The Originals Buoyancy Shorts For novice or intermediate level swimmers the major factor which prevents them from swimming faster is the lack of core stability and leg kick. Their arm strength and technique are good but because they are not horizontal on the top of the water they create a lot of drag and dead weight which makes it much harder to swim efficiently. With the buoyancy shorts the swimmer can get more used to swimming in the correct horizontal and streamlined position, so they start to build a neural pattern of how they should feel in the water. This also allows the swimmer to concentrate on making a more effective leg kick and better forward glide with each stroke, without that sinking leg feeling. With the extra buoyancy support, the swimmer can also focus more on the technique of their arm stroke, without the constant battle to keep the hips and legs in a high position in the water. Results have shown that over time a swimmer's body position, speed and endurance can be significantly increased by training with buoyancy shorts. Suitable for any level of triathlete who wants to refine their open water swimming technique whilst in a pool. Swimming in a wetsuit during a triathlon is very different to swimming without a wetsuit during a swimming race. The majority of your power needs to derive from your upper body whereas your legs and core provide the essential control. These shorts help develop your open water swimming technique whilst in the pool, where wearing a full wetsuit would either be too hot or banned.
