The Science of Speed: Unpacking Resistance and Propulsion in Elite Swimming
Doctor Ernie Maglischo is an ISCA & ASCA Hall of Fame Coach and still updating his most recent ebooks. Understand the biomechanics of swimming and explore how elite athletes generate propulsive force and minimize water resistance in the pool.
Drawing on expert analysis, we examine the fundamental characteristics of water flow, classifying water as a semi-solid whose density is over 800 times greater than air. Learn how competitive swimmers battle resistive drag—including form drag (profile drag) and lateral form drag—by maintaining laminar flow and optimal horizontal alignment.
This analysis confronts common misconceptions in stroke mechanics:
• Is Hip Rotation Propulsive? We challenge the popular notion that hip rotation is a source of propulsion in long-axis strokes (like the front crawl), arguing instead that it primarily serves to reduce water resistance and increase the effectiveness of arm and leg propulsion.
• The Best Arm Stroke: Compare the controversial deep-catch, straight-back pull (which some researchers suggest is superior for generating propulsive thrust) with the widely preferred curvilinear stroking and shoulder adduction used by the majority of elite swimmers in all four competitive strokes. We explore why the shoulder-adducting style may be universally used in longer events, while the deep catch may be superior for sprints (50m/yd).
Discover the true sources of speed:
• Vortex Theory: Understand how swimmers create vortices and a pressure differential to propel themselves forward. Propulsive thrust is generated because the pressure on the palm side of the hand is higher relative to the dorsal side, where pressure decreases due to vortex formation.
• The Catch: Learn why elite swimmers intentionally decelerate their hand speed to near zero during the crucial catch phase, positioning the arm backward before applying propulsive force.
• Wave Propulsion: Investigate unique propulsive concepts like wave propulsion (or “body wave”) and the importance of undulation in short-axis strokes (butterfly and breaststroke). See how breaststrokers like Mike Barrowman utilize streamlined positioning during the arm recovery to benefit from this wave phase, accelerating continuously for a short time.
The analysis in the ebook uses visualizations, including actual photographs of elite swimmers like Grant Hackett, Martin Lopez-Zubero, Mary T. Meagher, and video simulations/CFD renderings of water flow around limbs.
