SwimmersBest Method Ensures Chest Connection For Underwater Undulation

Science shows that underwater undulations are best when swimmers imitate eels and engage each undulation from the chest area to create a propulsive wave with the body. This stands in contrast to the more traditional idea of a “body dolphin.”  Body dolphin undulation creates propulsion primarily from knee kicks; this knee kick concept has a forward “propulsive phase” and a backward “recovery phase,” which greatly hinders the efficiency of undulations.

The process of a chest-lead body undulation generates opposing lines of force on each side of the body that ripple down the body to generate consistent propulsions. This eel-like undulation requires the swimmer to: finish each undulation past the midline in both the forward and backward phases, keep the ankles extended to finish each undulation, start each undulation from the chest/rib area, and engage muscles on the “recovery phase” of each undulation.

To help generate “feel,” muscle engagement, and muscle memory, SwimmersBest invented the Eel-fin, both a Regular and a Pro version. The SwimmersBest Regular Eel-Fin incorporates a moveable weight that acts as a pendulum to train novice swimmers to properly undulate to the front and back of their midline by feeling the shifting weight. In this situation, the weight acts as a pendulum like in a grandfather clock. As the weight is moved closer to the feet, the undulation rate quickens, and the size of the undulation decreases to help calibrate swimmers to the scientifically-proven rate of 0.40 to 0.45 seconds per undulation.

The newest member of the SwimmersBest Eel-Fin product line is the Pro Eel-Fin, a shorter and wider version of the Regular Eel-Fin. The Pro is used to create the muscle memory of straight ankles and closer knees and is designed for strong, efficiently-undulating swimmers that are 13+ years of age. On top of that, the Pro version allows the heels of the feet to naturally pivot outward into the propulsive phase and forces strong muscle development in the recovery phase. Through these features, the Pro Eel-fin is the final measure to ensure powerful undulations starting from the chest with a consistent wave through to the toes.

A further immense advantage of the Pro Eel-Fin is its ability to connect the body core to the full butterfly stroke. By helping to elongate both phases of the butterfly “kick,” the swimmer is encouraged to create a smaller amplitude undulation by engaging a range of core muscles throughout the stroke cycle. The Pro version is now being used by a host of Division 1 college teams and age group teams alike.

SwimmersBest is leading the way for the future of swim training equipment.  The company offers a broad range of solutions for improving stroke technique, kick technique, and breathing technique.   They provide swimmers, coaches, and teams with the tools they need to balance technique training with conditioning training.  By combining the best drills with the best tools, the SwimmersBest products give swimmers instant tactile feedback so they can adjust their technique efficiently.   The old way of having coaches constantly remind swimmers of their individual problems has proven to offer very little improvement in technique.  All SwimmersBest products are designed to constantly ‘talk to the swimmers’ so they can feel the problems and make corrections.   This unique approach means the swimmers are given negative feedback for incorrect stroke technique, which compels the swimmers to quickly correct the problem on their own. With a constant flow of new innovative product designs, SwimmersBest is a company that will continue to deliver solutions you need.

These people aren’t even in streamline????
Also, I disagree with the movement of arms and chest to create propulsion.

My coach during high school was very science driven in his training and methodology. I remember my senior year him saying at one point that as long as your arms were parallel with your head and tight that they didn’t have to be in a “traditional” streamline…this was one of the very few things that I disagreed with him on though. As somebody who was a strict underwater swimmer, I never felt as efficient if I wasn’t squeezing my ears during my streamline with my arms
