Body Position and Swim Technique

Improve Body Position and Swimming Technique

Fins add extra propulsion to the stroke, which increases a swimmer’s speed through the water. Good swimmers tend to plane on top of the water while poor swimmers tend to drag their legs and swim in a more vertical position slowing them down.

One of the goals of swimming faster with fins is to swim faster when the fins are taken off! By transferring the feeling of swimming faster and higher with fins to swimming without them, a swimmer makes use of a phenomenon know as neuromuscular patterning. The muscles and the nerves can actually remember the feeling of swimming faster and will try to duplicate the pattern the next time out. The more times the pattern is repeated (swimming faster and higher in the water with fins), the easier it is to duplicate it. The end result: the swimmer’s technique and neuromuscular coordination improves.

“The curves and flexibility of our blade design help keep the legs properly oriented for more efficient power, even as they fatigue.

Force Fin swimming fins utilize the body’s strength and put it where it’s needed. The human body is built to have more strength when kicking down (during freestyle), than when kicking up. The downward or power phase of the kick emphasizes the powerful quadriceps muscle group at the front and side of the upper leg.

The upward, recovery phase uses the weaker hamstrings at the back of the thigh. While still developing both sets of muscles, our blade design assists — or helps take the load off — the upward recovery phase that uses the weaker muscles, maximizing energy efficiency. Flat fins, other fins make your legs work as hard on the recovery as on the power phase of the cycle, because the flat rigid fins must push aside water to get back into position.

As you kick down, the blade pushes against the water engaging muscles of the whole leg and providing initial forward thrust.

At the end of the downstroke, the fin recoils, setting up to rebound to its original position during the recovery or return kick stroke.

The fin then rebounds to help begin the upward recovery phase of the two-cycle kick stroke.

The fin’s tips fold inward to aid the upward recovery and to prepare your leg for the next downward power stroke.

  • The snap of the blade helps increase kicking tempo keeping correct arms-to-legs coordination intact. There’s no worry about the kick slowing down unnaturally as with all other fins.
  • The rebound of the blade during the recovery phase helps bring the legs higher in the water (during free-style), raising the lower body to the surface in the desirable high-in-the-water position, where you encounter less drag and can swim faster and more efficiently.
  • Other fins, flat fins want to go through the water along the path of least resistance, which is sideways! Don’t believe it? Hold a flat, heavy object at the surface of the water, let go and watch what happens. It turns on its edge and heads for the bottom. Or, if it’s light like a sheet of paper, it will zig-zag or “dish” its way down. Neither action is going to help your kicking. With flat fins – even small or cutoff flat fins – a swimmer is constantly fighting all this twisting and torquing, and any effort spent this way is wasted.The curves and flexibility of Force Fin  blade design help keep the legs properly oriented for more efficient power, even as they tire.
