Swimming Technique Concepts: Trust In Swimming Science!<\/span><\/h1>\n
By Rod Havriluk<\/span><\/p>\n
Based on the many counterproductive technique elements that are conventional wisdom, it seems logical to ask why there is not a greater acceptance of science in swimming. The purpose of this article is to give swimmers and coaches some very real reasons to trust in science and scientists.<\/strong><\/p>\n
Distrust in science predates competitive swimming by many centuries. More recently, a 2019 survey by the Pew Research Center shows that only 35% of respondents have \u201ca great deal\u201d of confidence in scientists (Funk, Johnson, & Hefferon, 2019). Based on the many counterproductive technique elements that are conventional wisdom, it seems logical to ask why there is not a greater acceptance of science in swimming. The purpose of this article is to give swimmers and coaches some very real reasons to trust in science and scientists.<\/p>\n
In swimming, there are numerous technique examples that show science has not been fully embraced. The most obvious example of distrust in science (or, conversely, trust in conventional wisdom) is the prevalence of catch-up freestyle. With more than 20 years of research that consistently shows that an arm coordination with a positive index of coordination is necessary for fast swimming, catch-up stroke (which has a negative index of coordination) is still the most popular\u2014and decidedly counterproductive\u2014drill.<\/p>\n
Biomechanics research warrants trust because it is usually conducted by a credentialed expert. In addition, biomechanics applies established mechanical principles to biological systems. The mechanical principles are laws, not theories, and are irrefutable. Typically, a theory has been supported by research and is accepted as true until proven otherwise. A law is \u201calways true\u201d (Filmer, 2013).<\/p>\n
For example, three concepts of Sir Isaac Newton are known as Newton\u2019s Laws. Conservation of angular momentum is derived from Newton\u2019s Second Law and can be applied to an airborne diver. When a diver leaves the diving board, his\/her angular momentum is a fixed value\u2014calculated as the product of the angular velocity and the radius of rotation (the distance from the center of mass of the body to the center of mass) of each body segment. Since angular momentum must be conserved, that value is constant until acted on by another force, like the resistance of the surface of the water.<\/p>\n
If the diver tucks to somersault, angular velocity increases because the radius of rotation for the body segments decreases. The radius of rotation of the left foot is shown as an example. If the body straightens to a layout position, the angular velocity decreases because the radius of rotation increases. The law applies to every diver on every dive without exception.<\/p>\n

\nby Dan D\u2019Addona<\/strong>
\nIndiana\u2019s Carmel High School has won the girls\u2019 state swimming and diving championships for 34 straight years, a feat unequaled by any other high school\u2014not only in swimming, but in any other sport.<\/p>\n
012 BEST OF THE DECADE (2010-19)<\/strong><\/span>
\nIn Swimming World\u2019s first mythical national high school championships to determine the best teams of the last decade, Carmel High School of Indiana won both the girls\u2019 and boys\u2019 competitions.<\/p>\n

017 PREP POWER<\/strong><\/span>
\nby Andy Ross<\/strong>
\nSince Swimming World first began recognizing the top high school teams in the country in 1971, The Bolles School of Jacksonville, Fla., has won 18 national prep school titles\u201410 boys\u2019, eight girls\u2019. The Bulldogs have also captured 12 combined championships (public and independent schools), with both teams finishing No. 1 six times.<\/p>\n
020 THE GOLDEN YEARS OF HIGH SCHOOL SWIMMING<\/strong><\/span>
\nby David Rieder<\/strong>
\nPublic schools Santa Clara and Mission Viejo built high school swimming dynasties from the 1960s through the early 1980s. Not only did they dominate high school swimming, but unlike today, they also produced many of the swimmers from that era who competed in the Olympics.<\/p>\n
026 STILL CHASING EXCELLENCE<\/strong><\/span>
\nby John Lohn<\/strong>
\nMatt Grevers does not need to achieve anything more to stamp himself as an all-time great. But even at 35, there is a desire to accomplish more, and there is no reason to doubt Grevers can come through.<\/p>\n
029 SUMMER OF SPEED<\/strong><\/span>
\nby John Lohn<\/strong>
\nPolitics interfered at the 1976 Montreal Olympics, preventing South Africa\u2019s Jonty Skinner from competing head-to-head against the USA\u2019s Jim Montgomery in the men\u2019s 100 freestyle. But that summer, they became the first two swimmers to break the 50-second barrier in the event, with Montgomery clocking 49.99 at Montreal, followed by Skinner with a 49.44 at the AAU National Championships three weeks later.<\/p>\n
032 THE TROUBLE WITH SPRINTERS (Part 3): GARY HALL JR.<\/strong><\/span>
\nby Bruce Wigo<\/strong>
\nThe theme of this series of articles has been that sprinters are different from other swimmers\u2014athletes who have historically been considered troublemakers by the establishment, but who have been great for the sport. This month\u2019s featured sprinter is Gary Hall Jr.\u2014one of the greatest in Olympic history…but, perhaps, one of the most maligned and misunderstood.<\/p>\n
