Aqua Notes - The Race Club

The Race Club expands to Coronado, CA for their California Swim Camps


The Race Club, one of the world’s leading organizations teaching advanced swimming techniques, will relocate their California swim camps location from Los Angeles to San Diego beginning July 19th, 2016. The Race Club was responsible for training 53 Olympic swimmers that won 23 Olympic medals over 4 successive Olympic Games from 1996 to 2008. Since then, they have shared their knowledge and expertise by teaching swimming technique and training to swimmers and triathletes of all ages and abilities from around the world attending their camps or private instruction. The Race Club offers the most advanced technology available for improving swimming skills.

Coronado, California is an island in San Diego and home of a United States Naval Base and the west coast training site for the US Navy Seals.  It is a beautiful location surrounded by the Pacific Ocean and San Diego bay. With two Olympic pools within minutes of each other and easy access to many hotels, including the famous Hotel del Coronado, and restaurants, pristine beaches and open water, Coronado is the perfect destination for a Race Club Camp.In addition, just minutes away from Coronado are are several major attractions in the San Diego area including the San Diego Zoo and Safari Park, SeaWorld, Legoland and La Jolla. With year round moderate temperatures that have been called the most ‘comfortable climate in America’, the entire family will enjoy their experience in Coronado.

“It is hard to duplicate the beautiful setting and access to Olympic pools that we have in Islamorada, Florida, but we think Coronado will be its equal in California” says Gary Hall Sr., co-founder and Director of The Race Club. “Coronado is as accessible from the west coast of the United States as Islamorada is from the East. Also, with the Race Club’s global market of swimmers, Islamorada is easier to reach from Europe, while Coronado will be easier to reach from Asia. Both locations are easily accessible from Central and South America”.

Dr. Hall will be splitting his time teaching stroke technique between Islamorada and Coronado, but Race Club coaches and the most advanced technology will be available in both locations for camps and private instruction all year long.  Coronado, known for it’s aquatic lifestyle, with a rich tradition of producing outstanding water polo players, has welcomed The Race Club into its community.

The Race Club will be utilizing Coronado High School Brian Bent Memorial Aquatic Center and City of Coronado Aquatics Center pools to conduct private sessions and our California swim camps.

Breaststroke Kick with Rebecca Soni

Leave a comment

Breaststroke kick is one of the most challenging techniques of swimming. A powerful breaststroke kick relies on having great flexibility in the hips and dorsiflexion of the ankles. To kick with power in breaststroke, a swimmer must be able to push backward with the instep of the foot with great force and quickness. The hip flexibility may enable that to happen, but a swimmer must also develop strength in the hamstrings to draw the legs up quickly and in the quadriceps to push the feet backward with force in breaststroke kick.

Many swimmers that do not have enough flexibility in the hip attempt to increase the power of the kick by widening the distance between the knees. Yet this technique creates a problem. With widened knees, a swimmer cannot get through the kicking cycle fast enough to take advantage of the tremendous coupling energy from the upper body pressing forward and the head snapping down. By the time they start pushing the feet backward, the body’s motion downward has already stopped, lessening the propulsive force of the breaststroke kick. Olympic Champion Rebecca Soni has extraordinary hip flexibility and leg quickness. She draws her legs up quickly, once her pull force is completed, and begins to push backward quickly just as her upper body strikes the water. It is the exquisite timing of these motions that makes her so powerful in breaststroke.

At The Race Club, we have found the Finis yellow elastic band , placed above the swimmer’s knees, is an extraordinary tool to help swimmers keep their knees closer together during the breaststroke kick and develop a more effective and faster breaststroke.

Why the Late Front Breath in Butterfly Makes Sense


When children learn to swim butterfly for the first time, they often take a late breath in butterfly, pausing their arms at the end of the underwater pull before recovering the arms and taking the breath. We usually try to teach young swimmers to take the breath earlier in the underwater pull to avoid the delay in the arm recovery. While developing a faster pulling stroke rate is important in building a strong butterfly, it may be that the children have it right in delaying their breath.

Two of the fastest butterflyers in the world today, Joseph Schooling of Singapore and Chad Le Clos of South Africa, have a delayed front breath, though they achieve it in slightly different ways. Schooling initiates the head lift later in the underwater pull, while Le Clos holds the head up above water longer before dropping it down. In either case, the head snaps down later than when the front breath is taken earlier in the stroke.

The rationale for the late or delayed front breath has to do with the powerful coupling motions of the butterfly, which include the arms swinging forward during the recovery, the head snapping down and the shoulders/upper body pressing down. None of these motions provide any propulsive force, yet if timed correctly, they can add a tremendous amount of force to the second down kick in the fly cycle. The first down kick occurs when the hands are well into the propulsive phase underwater. The second down kick should be timed with the point of maximum kinetic energy of the coupling motions; when the hands, head and shoulders strike the water on their way down or forward. With the traditional early-breath fly technique, the head is already down before the second down kick occurs, contributing little or no coupling energy to this propulsive force. Similarly, the side breath contributes little or no energy to this second kick. Not so with the delayed front breathing technique.

Nothing is more demonstrative of the power of the coupling motions in butterfly than in the 2015 World University Games 200 finals of the 200-meter butterfly, where Japanese swimmer, Yuya Yajima, won a silver medal in the time of 1:55.7. What was unusual about this swim is that Yuya did that time with a stroke rate of 31, when everyone else in the race swam with a more typical stroke rate of in the high 40’s. Before that race, I would have bet my house that no one could swim a 200-meter fly in 1:55 with a stroke rate of 31. Thankfully, I didn’t.

Yuya’s technique, which has been called the ‘dolphin dive butterfly’, could accomplish that speed only through the use of a strong kick, great streamlining and powerful coupling motions. With the breath on each stroke, Yuya elevates high out of the water, arching the back (similar to breaststroke). Then he swings the arms forward aggressively, snapping the head and pressing the upper body down into a tight streamline, timing the arrival of all three at the surface of the water precisely with the second down kick. The hands are then held in front long enough to take the first dolphin down kick in this streamlined position. The result is an extraordinary surge forward underwater that enables him to be competitive with the other swimmers using a much higher stroke rate.

Neither Schooling nor Le Clos slow their stroke rates, yet by delaying the head snapping and the body pressing downward, they delay the peak of energy from those coupling motions to occur precisely with the second down kick. That leads to a greater surge forward under water after the kick. This technique is similar to the hybrid freestyle, where the swimmer with a strong kick can compete against faster stroke rates by increasing the coupling energy of the body rotation, head drop and faster arm recovery after the breath, leading to a surge forward under water.

Since all fast butterflyers have strong kicks, it makes the use of the delayed or prolonged front breath a plausible technique and worth trying. While in the 50-meter sprint, it is clearly faster to not breathe, for the 100 meters or longer, getting as much oxygen as possible is beneficial. Taking it later in the pulling cycle, rather than earlier, may just be best way to swim fly. Turns out, we may learn something from watching children starting to swim butterfly.

Develop a Turbocharged Engine for your Freestyle


Strong Freestyle 6 Beat Kick 

My wife drives an Audi Q5 that has a 4-cylinder engine with a turbocharged engine. I like the car because if I drive it conservatively, it gets really good gas mileage. Yet, if I need to pass someone quickly on the freeway, by pressing the accelerator hard, the car shifts into a much more powerful mode and picks up speed right away. Of course, it uses a lot more gasoline when I do that, but it is nice to know that I have that option when I need it.

One can look at the freestyle kick as being similar to the turbocharged engine. In the 50 meter sprint, every swimmer needs to push the accelerator all the way to the floor, maximizing the power of the kick all of the way. But in any event longer than 50 meters, one has to back off the accelerator some in order to keep from running out of gas. The longer the swim, the more careful one needs to be about pushing the legs into turbocharged mode. In the mile, for example, that mode is often reserved for the finish of the race. It is the turbocharged mode of the kick that enables Sun Yang to swim the last 50 meters in under 26 seconds, or Chris Swanson from U of Penn to swim the last 50 yards in 24.3 seconds and demolish the field. In fact, whenever there is a close race at the finish, I will always bet on the swimmer who has the turbocharged engine available in his/her legs.

The question is, ‘how does one develop a freestyle with the turbocharge option’? I have focused many of my articles and blogs on the importance of developing a strong kick, but the truth is, it is not easy to do. It requires developing extraordinary plantar flexibility of the ankle, leg strength for both the down and up kick motions, working both sides of the leg, and leg fitness; lots of it.

When you consider your pulling stroke rate, which may vary between 60 and 100 strokes per minute for any distance over 50 meters, with a 6 beat kick, the kicking stroke rate is 6 times that, or 360-600 kicks per minute. That means that during each stroke cycle, hand entry to hand entry, each leg takes 3 down kicks and 3 up kicks. Now consider that your 6 beat kick never really has any recovery time, as the legs are either pushing down or pulling upward at all times. That is a lot of sustained effort. It is no wonder that we cannot keep our legs in turbocharged mode for more than 50 meters without reaching exhaustion. If we are to use our legs in turbocharged mode for any part of the race, however, they simply must be extraordinarily fit; even more so than than our arms are.

Once you develop the turbocharge capacity in your freestyle kick by gaining ankle flexibility, leg strength and fitness, you must also learn how far down to push the accelerator for each race, and when to push the pedal all the way to the metal. The muscles of the leg are big and strong and if you use the turbocharged mode too early or too long, the lactate produced by this mode will ultimately shut you down.

Build a better swimming engine; one with a turbocharge capacity. Do so by working your legs incessantly, in and out of the water, developing the right tools for kicking propulsion. Then plan your longer races carefully, using the 4 cylinders at the beginning, getting good gas mileage, and saving the turbocharge option for the right time at the end. Then you can finish the race blowing by everyone, just like Sun Yang or Chris Swanson. It is a great feeling.

Yours in swimming,

Freestyle Swim Drills – 6 Kick 1 Stroke


The 6 Kick 1 Stroke drill is one of the most transformative freestyle swim drills we teach at the Race Club Camps. Ultra Marathon Swimmer Lexie Kelly and World Champion Junya Koga demonstrate this classic drill also known as ‘6 Kick Switch’ at the Race Club training grounds in Islamorada, Florida. This drill teaches two very important swimming techniques, body rotation and a relaxed wrist on the recovery. By placing an imaginary string from your shoulder to the sky the swimmer is asked to ‘touch the string’ on the recovery forcing a vertical position with the body. Swimmers that keep the wrist stiff or the fingers clenched together on the recovery can not recover the arm muscles for the next pull nearly as well as with a relaxed recovery. Junya Koga shows us another variation of these freestyle swim drills by sculling when his arm is out front.

It’s not the position on your side that gives you speed rather the quick rotation to the opposite side that creates a coupling motion with the kick and pull that makes them more powerful. Once you’ve mastered the 6 Kick 1 Stroke drill, move onto the 6 Kick 3 Stroke drill using the same arm recovery motion, the same body rotation and the same wrist relaxation for 3 successive strokes followed by 6 kicks on your side. Using these 3 freestyle swim drills; Body Rotation Drill, 6 Kick 1 Stroke Drill and 6 Kick 3 Stroke drill you can transform your stroke into a stronger more efficient technique leading to a faster freestyle.

“I wish we didn’t have to stop..” Those were the words of my youngest boy after him and his brother had spent this past weekend being coached by the fabulous and fantastic Amy Hall!
The sessions were intense, exciting, fun and highly informative and the boys could feel the difference in their swimming after a very short time of being coached. Amy’s knowledge and experience were very evident and she could advise the boys every step of the way. However, the her greatest ability and gift that she has is her ability to really relate to her swimmers. Her kindness and friendliness and willingness to listen meant a huge amount and ensured that the boys really enjoyed every moment of the sessions. She is a fantastic coach and a fantastic person and we were privileged to benefit from her knowledge and experience.
Thank you Amy!!

Backstroke Spin Drill


The backstroke spin drill is one of the most effective ways of teaching swimmers to accelerate the straight arms quickly through the recovery phase of the stroke cycle. One of the greatest challenges we see with our swimmers at The Race Club is getting them to turn their arms over fast enough in backstroke. In this Race Club Swimisode, World champion backstroker Junya Koga demonstrates how fast one can move the arms with the backstroke spin drill, preparing for a strong backstroke race. While a fast stroke rate in backstroke is not the only important technique to swim faster, it is critical, since most backstrokers turn their arms over way too slowly.

Many backstrokers are taught to deliberately slow their arms down before the hand enters the water, yet that is not what you should do. The faster the arm accelerates through the recovery, the more energy is coupled with the arm pulling underwater and the faster you will go. Don’t worry about being delicate or getting air bubbles trapped behind your hand. It is far more important to throw the arm backward aggressively and forcefully,with the little finger entering the water first, increasing the power and the speed of the stroke.

At the Race Club we are proud of the many backstrokers we have helped by using the backstroke spin drill. Try the spin drill with hands open or closed to increase your backstroke speed.

The Dynamics of Dolphin Kick Part II: Why Dolphin is Faster on the Back

The Dynamics of Dolphin Kick Part II: Why Dolphin is Faster on the Back

Using The Race Club’s Velocity Meter technology, I analyze the dolphin kick of world champion backstroker, Junya Koga. While on his stomach, he generates acceleration of about .7 m/sec2 on the up kick and 14 m/sec2 on the down kick, a significantly greater difference than one would expect on the basis of strength alone. The up kick results in a peak velocity of about 1.5 m/sec while the down kick results in a peak velocity of over 2 m/sec. However, like acceleration, a better representation of the power of the kicks is the difference between trough and peak velocities from both the up and down kicks (Delta PT). For the up kick, the delta PT is a trivial .1 m/sec and for the down kick, it is around .8 m/sec, also a significantly greater difference than one would expect based purely on strength.

When Junya dolphin kicks on his back, we find an extremely different velocity curve. Now, on the up kick, the stronger motion, we find a peak acceleration of around 3 m/sec2, while on the weaker down kick, we find an acceleration of around 5 m/sec2. The peak velocities of the down kick are also greater than the up kick, 2.1 m/sec compared to 1.9 m/sec. The delta PT is still greater on the up kick, but not by much, .4 m/sec compared to .35 m/sec. All of this suggests that the propulsion from the weaker down kick while dolphin kicking on the back is about the same or greater than the propulsion of the stronger up kick.

With the vast difference in biomechanical strength between these two motions, how can this be? It cannot be explained by a difference frontal drag, since the body positions are very similar. One coach, Rick Madge has proposed that the differences in power comparing the up kick and down kick while kicking on the back versus the stomach can be attributed to gravitational force. I don’t agree.

While gravity still applies in water, the actual force in water, reflected by our body weight, is considerably different. While the legs have negative buoyancy, they probably weigh only a few pounds in the water. That is not enough to affect our ability to kick up or down in water. I believe the differences observed on the velocity meter studies from front to back can be attributed to the vortices formed behind the body and feet of the swimmer.

When Junya is on his stomach, the down kick begins with the knees bent and the feet pushing back against the stream of water moving forward behind the body. The result from this strong motion against a current of water results in an extraordinarily strong surge of power and speed forward; more than one would expect from just the biomechanics.

With the up kick, the feet begin the upward movement below the stream from the body’s vortex and do not produce any meaningful propulsion until they enter the stream. By that time, the amount of propulsion is significantly less than that provided by the down kick. However, a strong upward and forward movement of the feet will create another vortex that will contribute to the stream and result in a greater force with the following down kick.

While on his back, Junya’s up kick begins with the feet below the stream and consequently, the feet do not produce as much force as when they are pushing against the stream. Again, the up kick will add even more power to the stream from the stronger vortex following the feet. When he begins the weaker down kick, he is now pushing against a substantial forward movement of water, almost as if he were pushing against a wall. As a result, there is a greater surge of velocity after the down kick than one would expect from this motion.

While all of these differing vortices may change the fluid mechanics of the kick, the important question is, which way is faster? In this particular study, Junya’s average dolphin kick speed on his stomach was 1.76 m/sec. On his back, it was 1.81 m/sec. .05 m/sec difference may not seem like much, but on an underwater kick off a start or turn lasting five seconds, that is 10 inches further ahead or behind that the swimmer would be; enough to win or lose a race.

I suspect that the difference in a swimmer’s speed from stomach to back has more to do with the law of inertia than to any difference in biomechanical strength or frontal drag. The lower delta PT on the back simply means that the kick is more efficient than while kicking on the stomach, since the swimmer maintains a more constant speed.

For completeness sake, we also tested Junya on his side and found that the velocity curves are similar to the ones on his stomach. The average velocity was measured at 1.71 m/sec, slightly slower than on the stomach, so there does not appear to be any clear benefit to kicking on one’s side compared to the stomach. Since the rules preclude us from remaining on our backs dolphin kicking during the underwater portion of a freestyle or fly race, we cannot recommend using this technique on any race other than the backstroke.

Ryan Lochte and other great backstrokers have figured out that they can kick dolphin kick faster on their backs than on their stomachs or sides. Now we know why.

Yours in swimming,

Butterfly with Roland Schoeman

1 Comment

Butterfly is a tough stroke to swim. It demands excellent fitness, strong legs, upper body and core, along with exceptional shoulder and ankle flexibility in order to perform well. Olympian and former butterfly world record holder Roland Schoeman makes it look easier with his graceful, yet powerful strokes across the pool. One of Roland’s secrets to swimming a faster butterfly is to enter his hands directly in front of his shoulders, rather than over or under reaching with the arm swing. He then initiates the pull quickly but maintains the elbows in a rather high position as he forcefully pushes his hands backward through the water . The high elbow position enables him to create propulsion from his hands without causing an excessive amount of frontal drag from the upper arms. Similar to the freestyle pull, but with both arms moving underwater at the same time, the high elbow pull in butterfly is a compromise from the maximum power possible, but is a technique that is required to reach the fastest speeds.

In swimming, we often need to learn to do what is right, rather than what feels right. That can be a challenge when we don’t feel the frontal drag forces working to slow us down. At The Race Club, we teach the right technique for each swimmer for all strokes With every stroke of butterfly taken, the precise timing of the two down kicks coupled with the recovery of the arms and the high elbow underwater pull is absolutely crucial for speed. Keeping the arm pull in the high elbow position enables the swimmer to get the hands through the stroke cycle faster, while reducing frontal drag. Watch Roland in this Race Club Swimisode and see how he has mastered this challenging butterfly stroke.
