Swimming: Refining your kick

5 09 2012

Among many things I have observed when trying to help some of my friends with their swimming is how difficult it is for them to correct their flutter kicks. Often times, the kick becomes more of a drag than a boost to their speed. More than just as a basic in swimming, it is skill that has to be continuously improved over time.

Browsing along to find advice, I found an article written for triatheltes in improving their swimming leg but can help normal folks like us improve on our swimming form. Took notes on some for myself as well. This is, by no means, written by me and all credit is due to the athlete who shared his insights for us to use.

Hope this helps.

How to refine your swim kick
by Gary Hall Sr. for Triathlete Europe

One of the great controversies in triathlon is the importance of the kick in swimming. Many triathletes feel it is better to rest the legs during a race, to save them for the bike and run. Others believe that kicking the right amount helps them swim faster and prepares the legs physiologically for a better bike and run.

Whichever strategy you think is best, one thing is certain: The function and importance of the kick are widely misunderstood. These are the four functions of your kick:

1. Propulsion
The legs can help you swim faster. To get any meaningful propulsion, one needs to use a six-beat kick, rather than a two-beat kick (see below).

2. Lift
The kick will keep your body straighter in the water and help lift the body closer to the surface to reduce drag.

3. Stabilizing force
Coupled with the counter-rotation of the core, the hardest kick should come toward the end of the propulsive phase of the underwater pull. This kick creates a force that helps increase the distance per stroke achieved.

4. Inertia
A six-beat kick—three times faster than the pull—helps sustain speed between arm strokes. This is a more efficient way to swim, rather than slowing down and speeding up through each stroke cycle.

Try the following exercises to improve your kick:
Increase ankle flexibility. Stretching the ankle allows you to increase the range of motion. The snap of the foot at the end of the kick provides much of the force of the kick, and a supple ankle maximizes this power.

Kick properly in training. Instead of “social kicking” with a board in practice, take it more seriously. Try using a mono snorkel and alignment kickboard from Finis. Not only will this put you in the correct body position for the swim, it will also enable you to practice streamlining while kicking. If you dedicate one entire practice per week just to kicking, you will do yourself a big favor.

Do dry-land leg exercises. You can increase strength and aerobic conditioning of your legs and core through appropriate dry-land exercises.

Two-Beat Vs. Six-Beat
In a two-beat kick, the right leg kicks down when the left hand enters the water and vice versa, followed by a slow lift of the leg. With a six-beat kick, the legs never stop kicking in either direction.
