The ASCA World Clinic is a can’t miss event – each year, the World Clinic showcases coaches from the highest levels of our sport, willing to share with all their knowledge, insights and wisdom. This year is no exception, with a lineup that includes Bob Bowman, Eddie Reese, Jack Bauerle and more.
But even more intriguing, this year, is what else is on the schedule.
Here are three must-attend talks for any coaching professional:
Councilman Memorial Lecture Series – Mr. Luis Lastra, US Navy Seals
The US Navy SEALS are sending Mr. Luis Lastra to the ASCA World Clinic to be the Doc Counsilman Memorial Lecture Speaker. Mr. Lastra will discuss the SEALS methodology for teaching the components of composure under extreme pressure, mental and physical toughness and retaining Mission focus. As swim coaches, we too are committed to building champions for life, and this talk is sure to provide meaningful lessons you can take home to your team. The Councilman Memorial Lecture Series was formed in tribute to one of the swimming profession’s most revered figures, James “Doc” Councilman. Each year, the lecture provides World Clinic attendees with a speaker from “outside” the coaching profession. In this way, we hope to honor Doc’s concept that our best learning comes from outside our own immediate environment.
Age Group Track – Mission Viejo Age Group Staff
The Mission Viejo Age Group Staff, a combined force of young and dedicated coaches serving under the tutelage of Coach Bill Rose, will share the Nadadores philosophy and discuss how the team successfully promotes the development of a strong, well-rounded age group program that continues to produce elite 18 and under athletes. The Mission Viejo Nadadores, one of the largest and longest continuously operating USA Swimming programs, recognizes the club development system as integral to achieving excellence. Hear about the team’s unique organizational structure and the challenges and advantages of working within a large staff. Learn how coaches Ad’m Dusenbury, Sarah Dawson and Bryan Dedeaux utilize coaching technologies and embrace positive teaching methods within dedicated peer-group practices. From training sets to dryland, meet selection to motivation, these coaches will share intricate details of the very fabric that makes up the Nadadores Tradition of Excellence.
Technical Emphasis – Nort Thornton and the amazing things he’s done with breastrokers
After Coach Nort Thornton “retired” as coach of the Cal Berkeley Men’s team he stayed on as an assistant coach and focused on the breaststrokers. The result?… His breaststrokers finished 1st, second, and fourth at last year’s NCAA Division 1 Championships. Here is short article Nort wrote and a nice preview to his presentation at the ASCA World Clinic: “My Thoughts of the New Breaststroke”… After coaching for fifty plus years as a head coach at the high school, country club, U.S. Swimming Club, Community College and NCAA division I levels, where I had sole responsibility of coaching the whole team on all of the four competitive strokes, I retired from the University of California at Berkeley where I have been for the last thirty-three years. I decided to volunteer to help out, and our present coach David Durden was kind enough to put me to work. We decided that I could be the most helpful if I looked after the breaststrokers swimmers, so that is what I have been doing for the last two years. It isn’t really work when you love what you are doing.

Swimming Psyche Outs: How to be in control, confident and composed when faced with psyche outs (and how to use them to your advantage!).
By Genadijus Sokolovas, Ph.D. Senior Physiologist
Global Sport Technology, Inc.
A new Swim Power test was developed by the Global Sport Technology, Inc to analyze the changes of swimming velocity (m/sec), force (kg), acceleration (m/sec/sec), and power (kg x m/sec). All these parameters are recorded instantaneously 60 times per second (60 Hz) at specific points in the swim stroke. Testing results are synchronized with video software to superimpose them with underwater video in real time and then recorded later on a DVD for easy review.
The Swim Power test quantifies every phase of individual stroke. Swimmers have different strengths and weaknesses, which can be identified using the Swim Power test. Some swimmers may have very strong beginning of stroke, while others may be stronger in the middle or at the end of the stroke. There are differences between left and right arm stroke, between left and right leg kick, timing between various phases of the stroke, etc. There is no “perfect stroke.” Even elite level swimmers have plenty of room to improve their swimming technique. By identifying individual strengths and weaknesses using the new Swim Power test, we can develop drills and swimming sets to improve everybody’s swimming technique.
Testing Protocols for Swimmers Variety of testing protocols may be used testing the Swim Power. Depending on individual goals, swimmers may be tested in full body swim, pulling or kicking only, underwater kicking after turns and dives, swimming fully rested and under fatigue, and many other positions. Coaches and athletes can even test advantages and shortages of different swimming techniques. Swim Power test will reveal strengths and weaknesses of every type of swimming technique. The standard Swim Power testing protocol for freestyle and backstroke includes three 25 meters efforts at race pace in various positions unique to the specific stroke analyzed:
- Pull with buoy (Figure 1)
- Kick (Figure 2)
- Swim (Figure 3)
Figure 1. Pull position.
Figure 2. Kick position.
Figure 3. Swim position.
The vertical green line in the middle of the graph indicates swimmer’s position on the video. Real time velocity and force parameters at every point of the swimming cycle are displayed below the graphs. Kicking is done with a kickboard for freestyle, butterfly, and breaststroke. Backstroke kicking is tested in streamline position without a kickboard. In addition to these kicking positions, underwater fly kick may be tested for flyers, backstrokers, and freestylers (Figure 4).

Analysis of Swim Power Testing Results
Analysis of testing results is based on changes of swimming velocity (force, acceleration, and power) during the swim cycle. Since every swimmer has different strengths and weaknesses, feedback includes individual recommendations/drills to improve swimming (or water polo) technique.
Every swim stroke has specific changes of swimming velocity. The largest changes of velocity in swimming cycle are for breaststroke and butterfly. Normally, larger changes of velocity in swimming cycle are related to higher energy expenditure. In fact, studies in exercise physiology (Sokolovas & Woodruff, 2004, etc.) proved that butterfly and breaststroke are the most energy demanding strokes. A typical velocity curve in breaststroke is presented in Figure 8.
Figure 8. Breaststroke velocity curve (digitizing).
Individual recommendations from the new Swim Power test are focused on:
- Reduction of time at slow phases of the stroke
- A smaller drop of swimming velocity at slow phases of the stroke
- Maintaining higher swimming velocity for a longer time at fast phases of the stroke
- Minimizing fluctuations of velocity during the swimming cycle
Recently we developed Swim Power software, which quantifies/digitizes changes of swimming velocity in every stroke. The software analyzes many different parameters, such as average of swimming velocity during the fastest and slowest phases of the swim cycle, changes of swimming velocity during the swim cycle, velocity at various points of the cycle, timing of various phases of swim cycle, and many others. For instance, digitizing of breaststroke (see Figure 8) includes calculation of average velocity at every point of the stroke (at A, B, C, D, and E), velocities at all phases (A-B, B-C, etc.), average percent increase/decrease in velocity (from A to B, B to C, etc.), average percent time for each phase (A-B, B-C, etc.), and some other parameters. The number of swim cycle parameters is between 24 and 32 depending on the complexity of swim stroke.
