Velocity Meter-Breaststroke Swimming by Team Termin



In this clip, the swimmer is first viewed part way through the pullout phase of the underwater pullout. Notice that velocity drops to zero, during the recovery phase of the arms and the legs. This is caused because the initial glide phase before the pull is to long, and the swimmer has traveled two far down the deceleration curve. (See Push off and glide video and description) The recovery phase creates so much drag, and the swimmer has slowed to a point that zero velocity is attained.

Re-acceleration occurs as the swimmer reaches the surface. The velocity associated with breastroke is clearly demonstrated in this clip. Performance improvements occur when the large declarations in the is stroke are reduced. The velocity meter integrates underwater video with a tracing (red line) of instantaneous velocity. The black line scrolling across the red tracing is synchronized with video, so the swimmers technique can be analyzed into parts of accelerations, and decelerations. To help swimmers improve, this method is helpful in identifying specific parts of the stroke creating the most drag. After that part is identified, the swimmer and coach can concentrate on strategies in the area where significant improvement in performance can occur.
