WHY USE FINS?
|Swimmers – along with scuba divers and body surfers – have been using fins for decades,but only recently have coaches and swimmers alike begun to appreciate what these excellent training tools can do to help people of all ability levels improve their swimming.
Increase fitness and Cardiovascular Conditioning Although swimming is considered one of the best aerobic or cardiovascular-conditioning exercises, many people forget to use their legs where the largest muscles are located. Since the greatest cardiovascular benefits come from including the highest percentage of the body’s muscles – that’s why cross-country skiing and rowing are considered two of the most demanding sports – it makes sense that swimmers who activate the large muscle mass of the legs by kicking will benefit from a more demanding workout that burns more calories and increases fitness levels.
Add fins to the equation and the increased load they add to the legs means that as long as exertion levels remain high, the cardiovascular system gets an even more intense workout with even greater fitness benefits. Unlike all other fins, even those with open toe drains, “OnlyForce Fin swimming fins are designed to concentrate the force of the blade further back on the foot, using the muscles of the whole leg, not just the lower leg.”
Develop Leg Strength Kicking with fins is like lifting weights: the added resistance of the water on the blade of the fin increases the workload on your leg muscles. Your body adapts by increasing the strength and endurance of the muscles involved. Stronger muscles move more water making you swim faster, all other things being equal.
A word about specificity: It’s important to realize that muscular strength for swimming needs to be “specific.” Good runners, cyclists, roller bladers, etc. can have very strong leg muscles, but the muscles have developed for running, cycling or roller blading, not for swimming. Fins develop leg strength specifically for swimming, and in a way that few other activities can.
Improve Body Position and 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.
|WHY USE FORCE FIN SWIMMING FINS?|
|We’ve been designing and making improvements to fins for over 25 years, with hundreds of thousands of satisfied customers, and many major product design awards under our belts, we can honestly say that we are the experts in fin design. That’s all we do, and we think our innovative fins are without equal in terms of comfort, efficiency, durability, performance, versatility and sheer value for your money.
We offer a variety of fins and each as been developed in response to your needs, comments and suggestions. Studying marine animal locomotion and human biomechanics, we have researched and designed our fins to take advantage of the laws of nature and physics. Not to mention common sense.
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.
Open Foot Pocket Design Unlike all other fins, even those with open toe boxes, only FORCE FIN swimming fins are designed to concentrate the force of the blade further back on the foot, using the muscles of the whole leg, not just the lower leg.
Try this simple test to see the difference between how our fins work compared to other brands.
|While seated, cross your ankle over your knee, grab your toes and pull them in the direction of the sole of your foot. Do you feel the stretch and tension running from the top of your foot up and along the shin? Those are the primary muscles that other fins work because the fin blade extends from your toes.|
|Now, grab the foot in both hands – one holding the heel, the other holding the top of the foot – pull again toward the sole of the foot and resist with the leg. The tension has moved up to the upper leg, hasn’t it?|
|As you kick down, the blade pushes against the water engaging muscles of the whole leg. The water is pushed behind and through the split in the fin to provide 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.||Assited by the rebound, the fin throws and directs water behind, faster than you can kick it with any other fin. The fin’s tips fold inward to aid the upward recovery and to prepare your leg for the next downward power stroke.||At the same time, it resets and recovers your leg into position for its next forward kick stroke.|
|Inspired by Nature Have you ever seen a fast-swimming fish with a blunt or squared-off tail? Neither had we. That’s why we patterned our fins after the split-V shape of fish tails that more efficiently channel the water. The other brands of swimming fins still use the cheaper-to-make, straight-across design.
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.
We also noticed that other fins worked basically like boards tied to your feet; they were stiff and inflexible. Again, we took our cue from nature and physics, and we came up with very flexible fins using innovative materials like polyurethane instead of rubber. The curves and flexibility of our blade design help keep the legs properly oriented for more efficient power, even as they fatigue.
FORCE FINS or SLIM FINS? Force Fins are our original design, and being somewhat larger than Slim Fins, they provide a more concentrated leg workout (more resistance). They are a more versatile fin, in that they can be used for other sports, such as snorkeling, SCUBA and float tube fishing. From a swimming perspective, they are a very specific training tool and are excellent for butterfly, “new-wave” breaststroke, and the backstroke dolphin kick.
Slim Fins are narrower than the Force Fin and are specifically designed for pool swimming – especially freestyle – applications. With Slim Fins, the blades don’t touch, flip turns are no problem, and high stroke turnover or cadence is easily maintained.Slim Fins can be used either while swimming or in kicking-only drills. They receive the highest recommendations from swimming coaches and professionals, and will do the best job for and are the best choice for most swimmers.
|Other swim fin choices: Multi Force are a short bladed swim training fin, with a foot pocket that adjusts to fit a wide variety of feet, with an added twist. You can add Force Wings to vary the output of your fin, to work harder or faster. You can even fine-tune the Wings to target specific muscles or stroke correction needs. They are great for reconditioning, lap swimming and threshold training.
HOW ARE THEY MADE? Manufactured in the USA and backed by over 30 years of research and development, Force Fin swimming fins are made of ultraviolet-, abrasion- and chemical-resistant polyurethane and heat-treated for 16 hours at temperatures where other fins melt. This process allows the molecules to cross-link giving the blade its snappy, high-performance characteristics and extreme durability. Unlike other brands, Force Fin swimming fins will not melt on hot pool decks or mark the sides of pools, and should last season after season, even when used daily. We could go on forever describing the unique benefits of using Force Fin swimming fins to improve your swimming. But there’s only one way to really find out why our fins are the best swimming fins in the world: try a pair you will be happy!
