The S-stroke in front crawl could be more effective for triathletes, rather than the I-stroke, new research from the\u00a0University of Tsukuba in Japan shows.<\/strong><\/p>\n

\u00a0The scientists investigated which stroke was more effective in the water; the S-stroke when the arm draws a curve in the water or the I-stroke when it moves straight, and found that the effectiveness of the stroke depended on the distance swum. According to their results the S-stroke is better suited for swimming middle and long distances, when you need propulsive power with less physical exertion, while the I-stroke is better for short distances, which depend on speed over efficiency.<\/p>\n

The study explains that this is because \u201cthe mechanisms of propulsive power differ between the two strokes. The vortex pairs generated by the S-stroke, with the arm changing orientation in the water, cause unsteady lift force, while the I-stroke\u2019s straight movement causes K\u00e1rm\u00e1n vortices that produce drag force.\u201d<\/p>\n

However this research doesn\u2019t take into account coping with open-water.<\/p>\n

\u201cI-shaped pulls and S-shaped pulls are at extremes of the spectrum. Most people will fit somewhere along that, rather than at either end, depending on height, reach, power, flexibility and feel for the water, a point that will feel most natural to them,\u201d says\u00a0John Wood, 220 Triathlon<\/em> swimming coach.<\/p>\n

\u201cThe way I look at it is that if you have a decent hold on the water with hands and forearms, you \u00a0can look to pull relatively straight but your hand\/arm will follow a \u00a0slight S shape naturally as it tries to find the still water. From there you don\u2019t really need to accentuate the shape. (Actually the more you try and exaggerate the S, the more likely you are to cross under the middle of your body). Rather than worrying too much about the route that the hand takes back under the water, more focus for beginners and experienced swimmers alike should be on ensuring constant pressure on the hand\/forearm throughout the pull phase.\u201d<\/p>\n

220<\/em> staff writer Jack Sexty says: \u201cThere may be truth behind the research\u00a0claiming\u00a0that the S-stroke may be the most efficient technique on paper, but it\u2019s important to remember that open-water swimming can throw up a whole host of variables that this research doesn\u2019t\u00a0account for.<\/p>\n

\u201cMany fast open-water swimmers, such as Harry Wiltshire and Jonny Brownlee,\u00a0employ a\u00a0faster turnover with a straight-arm pull whilst drafting other swimmers\u00a0\u2013\u00a0a faster turnover can help open-water swimmers to keep moving over waves or chops in the water, whilst\u00a0employing\u00a0a longer pull could actually work against you if rough water\/chop from other swimmers is\u00a0disturbing\u00a0your stroke anyway. The research also assumes the swimmer will be employing the\u00a0technique correctly in the first place \u2013\u00a0and an incorrect s-stroke is far less efficient than a well executed straight-arm pull!\u201d<\/p>\n<\/div>\n
