Who Invented SwiMetrics?

Genadijus Sokolovas, Ph.D. (shown to the left with Michael Phelps) invented SwiMetrics. Dr. G, as he is known, is considered by many to be one of the world’s most accomplished sports physiologist and the world’s most successful swimming scientist who has developed numerous applications that are widely used throughout the sport of swimming.


Genadijus was USA Swimming’s Director of Physiology & Director of Sport Science from 2000 to 2008. He developed several innovative testing programs for USA Swimming Olympic and National Team members, including lactate clearance tests (shown below with Olympic medalist Erik Vendt, land/water strength tests, biomechanical analysis and training design programs.

Genadijus tested, evaluated and advised USA Swimming National Team and Olympic Team athletes and coaches before and during all major international competitions and Olympic Games between 2000 and 2008, including gold medalists and world record holders Michael Phelps, Natalie Coughlin, Dara Torres, Jenny Thompson, Ryan Lochte, Aaron Peirsol, Brendan Hansen, Ian Crocker, Katie Hoff, Kate Ziegler, Misty Hyman, Amanda Beard, Tara Kirk, Megan Quann-Jendrick, Neil Walker, Gary Hall Jr., Anthony Ervin, Ed Moses, Lenny Krayzelburg, Jason Lezak, Cullen Jones and more than 2,000 world-class swimmers.

Genadijus has provided testing feedback and advice to coaches at Stanford, California Berkeley, Texas, Michigan, Florida, Southern California, Alabama, Auburn, Arizona, Arizona State, North Carolina, South Carolina, Washington, Oregon, Nevada, Utah, Denver, Colorado State, and many other universities.

Genadijus has also provided feedback and advice to numerous coaches and Olympic athletes in triathlon, running, cycling, modern pentathlon, fencing and wrestling. He has worked with United States Olympic Committee on supplemental oxygen training, use of altitude tents, vibration training/treatment, use of blood testing results, use of saliva testing results and use of urine testing results. He has also given presentations in many countries on training adaptation, recovery, altitude training, biomechanical analysis.

Before his work at USA Swimming, Genadijus was the Dean of Coaching Faculty at the Lithuanian Academy of Physical Education between 1987-2000 where he served as the Scientific Advisor of Lithuanian Swimming, Modern Pentathlon and Track & Field. Also as the Head of Laboratory of Computerization in Sport, Genadijus optimized training strategies in swimming, running, race walking, modern pentathlon and triathlon, and developed mathematical models of adaptation of athletes in career, seasonal and weekly training.

Genadijus received his doctorate from the Russian Academy of Physical Education in Moscow where he used physiological, biochemical, and pedagogical testing programs to assess adaptation in swimming to different workloads.

What is SwiMetrics?

SwiMetrics is the world's most sophisticated swimming analytical tool for swimmers, water polo players and triathletes.

SwiMetrics measures and records the velocity (speed in meters per second) and force (in kilograms) at specific points in the swimming stroke. The test results are synchronized with DartFish software to superimpose velocity and force curves (60 times per second) with an underwater video of the athlete.

The vertical green line in the middle of the SwiMetrics videos shown below indicate the swimmer's position on the video. The real-time velocity data at every point in the swimming cycle is represented by a "Velocity Curve" (which is the continuous white line shown below the swimmer in the video). It is used by pool swimmers, open water swimmers, channel swimmers and water polo players.

SwiMetrics of a Masters Swimmer from Irvine, California

On January 2nd, 2009, an athlete from the Irvine NOVA Masters Swimming was tested using SwiMetrics.

The athlete was tested in a variety of 20-yard race-pace swims. In the video shown below, the athlete is swimming at 1.6524 meters per second at that point in his stroke.

SwiMetrics of a Water Polo Player from Huntington Beach

On January 2nd in Southern California, several Huntington Beach High School swimmers and water polo players were tested using the SwiMetrics, the world's most sophisticated swimming analytical tool for swimmers, water polo players and triathletes.

SwiMetrics measures and records the velocity (speed in meters per second) and force (in kilograms) at specific points in the swimming stroke. The test results are synchronized with DartFish software to superimpose velocity and force curves (60 times per second) with an underwater video of the athlete.

The vertical green line in the middle of the graph indicates the athlete's position on the video (shown below). The real-time velocity data at every point in the swimming cycle is represented by a "Velocity Curve" (the continuous white line shown below the athlete in the video).

The athletes were tested in a series of 20-yard race-pace swims including pulling with a pull buoy and sprint freestyle.

In the video shown below, the high school water polo player is swimming at 1,458 meters per second at that point in her stroke.
