In breaststroke, because swimmers must raise the head and shoulders in order to
breathe, they are often prone to hyperextension/overarching of the back.
Hyperextension of the back means the swimmer moves towards a vertical
position in the water, which is hydrodynamically inefficient.
The Corsuit alerts the swimmer to any such movement, as they will feel an
increased pressure from the top of the Corsuit. This reminds the athlete to
maintain a flatter position as they breathe, helping to maintain forward
momentum despite some upward movement.
As the swimmer then reaches forward and initiates the kick, the back flattens
and they move towards a Flat Back position for the glide phase.
