Swimming Technique Concepts:
\nMaximizing Swimming Velocity Part 4 – Minimizing Arm Entry Phase Time In Backstroke and Breaststroke<\/span><\/strong><\/h1>\n

By\u00a0Rod Havriluk<\/span><\/p>\n

 <\/p>\n

As shown in a previous \u201cSwimming Technique Concepts\u201d article (SW June 2021<\/a>), when swimming velocity increases, the time of all four stroke cycle phases decreases. Conversely, swimmers decrease the time of all four phases of the stroke cycle to increase swimming velocity. Of all four phases, the greatest decrease was in the entry phase. A swimmer who can further decrease the entry phase time will be able to further increase swimming velocity.<\/p>\n

FIG. 1 >The graph shows the time for the four phases of the stroke cycle in backstroke and breaststroke from two studies.<\/p><\/div>\n

The graph in Fig. 1 shows the time for the four phases of the stroke cycle in backstroke (Chollet, Seifert & Carter, 2008) and breaststroke (Leblanc, Seifert, Baudry & Chollet, 2005) for elite male swimmers. (The breaststroke glide phase is the equivalent of the arm entry phase in the other three strokes, as it occurs between the end of the arm recovery and the beginning of the pull. The inward and outward sculling motions of breaststroke are the equivalents of the pull and push phase of the other three strokes.)<\/p>\n

FIG. 2 > Backstrokers often add time to their arm entry by flexing at the elbow so that the hand enters behind the head instead of behind the shoulder (yellow line).<\/p><\/div>\n

 <\/p>\n

BACKSTROKE ENTRY PHASE<\/span><\/strong>
\nBackstrokers often increase the arm entry phase with two ineffective motions:
\n1. Entering the hand behind the head instead of behind the shoulder (Fig. 2), and
\n2. Moving the hand primarily sideways instead of primarily downward after it submerges (Fig. 3).<\/p>\n

The underwater front-view video image of the backstroker in Fig. 3 shows that he moves his hand primarily sideways instead of downwards on the entry phase. He required 3-tenths of a second from when the hand submerged until the hand was below the shoulder and in position to generate propulsion.<\/p>\n

SWIMMING WORLD AUGUST 2021 FEATURES<\/p>\n

012<\/span> |<\/span> READY FOR A NEW CHALLENGE<\/strong><\/span>
\nby David Rieder<\/strong>
\nTorri Huske finished her high school career by setting national high school records in the 100 yard fly and 200 IM and by being named Swimming World\u2019s Female High School Swimmer of the Year for the second time (2019, 2021). The 18-year-old senior from Yorktown High School (Arlington, Va.) will be moving on to Stanford in the fall, but first, she set an American record in the 100 meter fly at U.S. Trials that earned her a trip to Tokyo to compete in her first Olympics.<\/p>\n

014<\/span> |<\/span> TAKING IT TO THE NEXT LEVEL<\/strong><\/span>
\nby Dan D\u2019Addona<\/strong>
\nEverything appears to be OK for Norman North (Okla.) High School senior Aiden Hayes. He set two national high school records (100 fly and 50 free) this past season. He competed and gained experience at the U.S. Olympic Trials as the fastest 18-year-old in the country in butterfly. And he was named Swimming World\u2019s Male High School Swimmer of the Year.<\/p>\n

016<\/span> <\/span> |<\/span> CREAM OF THE CROP<\/strong><\/span>
\nby David Rieder and Andy Ross<\/strong>
\nThere were some mighty fast swimmers who finished the 2020-21 high school season right behind Swimming World\u2019s Female and Male High School Swimmers of the Year, Torri Huske and Aiden Hayes. Of the four runners-up, two of them are underclassmen and will be returning for more fast swimming in 2021-22.<\/p>\n

018 <\/span> |<\/span> TOP HIGH SCHOOL RECRUITS<\/strong><\/span>
\nby Chandler Brandes<\/strong>
\nSwimming World takes a look at the swimmers it considers to be the 10 best high school recruits\u2014both male and female\u2014from the Class of 2021 and where they\u2019ll be attending college in the fall.<\/p>\n

\nby Dawn Weatherwax<\/strong>
\nTo reach your swimming goals, it is important to know what to eat\u2014at what times and in what amounts. It is different for everyone, but very important to master.<\/p>\n

022 <\/span> |<\/span> ISHOF: THE U.S. OLYMPIC TRIALS\u2014DONNA DeVARONA AND THE PAST, PRESENT AND FUTURE OF WOMEN\u2019S SWIMMING<\/strong><\/span>
\nby Bruce Wigo<\/strong>
\nAt the recent U.S. Olympic Trials, there was one moment that linked the past with the present and future of swimming like no other. It came when Donna de Varona presented Olympic qualification medals to Katie Grimes, the youngest member of the 2021 Olympic swimming team, and three-time Olympian Katie Ledecky.<\/p>\n

025<\/span> |<\/span> ONE OF THE GREATEST SPRINTERS OF ALL TIME<\/strong><\/span>
\nby John Lohn<\/strong>
\nThe 2000 Olympic Games in Sydney are widely remembered for the home-nation success of Australia, which was spearheaded by teenage sensation Ian Thorpe. But the Games Down Under also served as a redemptive locale for the Netherlands\u2019 Inge de Bruijn, who used the stage to define herself as one of the sport\u2019s legends.<\/p>\n

034<\/span> | <\/span> SWIMMING TECHNIQUE CONCEPTS: MAXIMIZING SWIMMING VELOCITY (Part 4)\u2014MINIMIZING THE ARM ENTRY PHASE TIME IN BACKSTROKE AND BREASTSTROKE<\/strong><\/span>
\nby Rod Havriluk<\/strong>
\nTo minimize the arm entry phase time in backstroke, a swimmer must quickly move the hand downward directly behind and below the shoulder. Minimizing the arm entry phase (glide phase) in breaststroke requires precise control of the timing between the finish of the kick and the beginning of the pull. A decrease in the non-propulsive entry phase decreases the time for a stroke cycle, increases stroke rate and increases swimming velocity.<\/p>\n

038 <\/span> |<\/span> SPECIAL SETS: ENERGY SYSTEM TRAINING<\/strong><\/span>
\nby Michael J. Stott<\/strong>
