This month\u2019s article includes more general information about force analysis with a backstroke example.<\/p>\n<p>The importance of measuring the force variations within each stroke cycle was emphasized in a study on backstroke (Formosa, Mason &amp; Burkett, 2009). The authors noted that the elite swimmers in their study each produced \u201cdistinctive propulsive force profiles\u201d that identified technique limitations that could be further described with underwater video. They concluded that their study demonstrated the importance of force data synchronized with video.<\/p>\n<p>A study on backstroke conducted by a coach exemplifies the magnitude of improvement that is possible in a short time, using feedback about hand force (Jefferies, Jefferies &amp; Donohue, 2012). At the beginning of the week, each swimmer was pre-tested for his\/her hand force. During the week each swimmer had a 30-minute daily session in a flume with instruction and real-time feedback from video and force data.<br \/>\nAt the end of the week, each swimmer was post-tested. The improvement in average force was 22%.<\/p>\n<p style=\"text-align: center;\"><strong>To access the complete study and results of hand force analysis for the backstroke,<\/strong><br \/>\n<strong><a href=\"https:\/\/www.swimmingworldmagazine.com\/issues\/2020\">the May 2020 issue is now available for download in the Vault!<\/a><\/strong><\/p>\n<p style=\"text-align: center;\"><a href=\"https:\/\/www.swimmingworldmagazine.com\/news\/product\/swimming-world-magazine-may-2020-issue-pdf-only\/\" target=\"_blank\" rel=\"noopener noreferrer\" data-auth=\"NotApplicable\"><span style=\"color: #0000ff;\">Non-Subscribers Can Download The Issue Here<\/span><\/a><\/p>\n<p><a href=\"https:\/\/www.swimmingworldmagazine.com\/issues\/2020\/swimming-world-magazine-may-2020-issue-pdf-only\" target=\"_blank\" rel=\"noopener noreferrer\"><img loading=\"lazy\" decoding=\"async\" data-attachment-id=\"429582\" data-permalink=\"https:\/\/www.swimmingworldmagazine.com\/news\/swimming-world-may-issue-dave-durden-leader-of-men-free-limited-time-download\/sw-may-2020-cover-dave-durdan-leader-of-men\/\" data-orig-file=\"https:\/\/vmrw8k5h.tinifycdn.com\/news\/wp-content\/uploads\/2020\/04\/SW-May-2020-Cover-Dave-Durdan-Leader-of-Men.jpg\" data-orig-size=\"800,1070\" data-comments-opened=\"1\" data-image-meta=\"{&quot;aperture&quot;:&quot;0&quot;,&quot;credit&quot;:&quot;&quot;,&quot;camera&quot;:&quot;&quot;,&quot;caption&quot;:&quot;&quot;,&quot;created_timestamp&quot;:&quot;0&quot;,&quot;copyright&quot;:&quot;&quot;,&quot;focal_length&quot;:&quot;0&quot;,&quot;iso&quot;:&quot;0&quot;,&quot;shutter_speed&quot;:&quot;0&quot;,&quot;title&quot;:&quot;&quot;,&quot;orientation&quot;:&quot;1&quot;}\" data-image-title=\"SW May 2020 Cover &#8211; Dave Durdan &#8211; Leader of Men\" data-image-description=\"&lt;p&gt;SW May 2020 Cover &#8211; Dave Durdan &#8211; Leader of Men&lt;\/p&gt;\n\" data-image-caption=\"\" data-medium-file=\"https:\/\/vmrw8k5h.tinifycdn.com\/news\/wp-content\/uploads\/2020\/04\/SW-May-2020-Cover-Dave-Durdan-Leader-of-Men-700x500.jpg\" data-large-file=\"https:\/\/vmrw8k5h.tinifycdn.com\/news\/wp-content\/uploads\/2020\/04\/SW-May-2020-Cover-Dave-Durdan-Leader-of-Men-766x1024.jpg\" class=\"aligncenter wp-image-429582 size-full\" src=\"https:\/\/vmrw8k5h.tinifycdn.com\/news\/wp-content\/uploads\/2020\/04\/SW-May-2020-Cover-Dave-Durdan-Leader-of-Men.jpg\" alt=\"SW May 2020 Cover - Dave Durdan - Leader of Men\" width=\"800\" height=\"1070\" srcset=\"https:\/\/vmrw8k5h.tinifycdn.com\/news\/wp-content\/uploads\/2020\/04\/SW-May-2020-Cover-Dave-Durdan-Leader-of-Men.jpg 800w, https:\/\/vmrw8k5h.tinifycdn.com\/news\/wp-content\/uploads\/2020\/04\/SW-May-2020-Cover-Dave-Durdan-Leader-of-Men-766x1024.jpg 766w, https:\/\/vmrw8k5h.tinifycdn.com\/news\/wp-content\/uploads\/2020\/04\/SW-May-2020-Cover-Dave-Durdan-Leader-of-Men-150x201.jpg 150w, https:\/\/vmrw8k5h.tinifycdn.com\/news\/wp-content\/uploads\/2020\/04\/SW-May-2020-Cover-Dave-Durdan-Leader-of-Men-300x401.jpg 300w, https:\/\/vmrw8k5h.tinifycdn.com\/news\/wp-content\/uploads\/2020\/04\/SW-May-2020-Cover-Dave-Durdan-Leader-of-Men-450x602.jpg 450w, https:\/\/vmrw8k5h.tinifycdn.com\/news\/wp-content\/uploads\/2020\/04\/SW-May-2020-Cover-Dave-Durdan-Leader-of-Men-673x900.jpg 673w, https:\/\/vmrw8k5h.tinifycdn.com\/news\/wp-content\/uploads\/2020\/04\/SW-May-2020-Cover-Dave-Durdan-Leader-of-Men-374x500.jpg 374w, https:\/\/vmrw8k5h.tinifycdn.com\/news\/wp-content\/uploads\/2020\/04\/SW-May-2020-Cover-Dave-Durdan-Leader-of-Men-245x327.jpg 245w, https:\/\/vmrw8k5h.tinifycdn.com\/news\/wp-content\/uploads\/2020\/04\/SW-May-2020-Cover-Dave-Durdan-Leader-of-Men-533x713.jpg 533w\" sizes=\"auto, (max-width: 800px) 100vw, 800px\" \/><\/a><\/p>\n<p style=\"text-align: center;\">[PHOTO CREDIT: SPEEDO USA]<\/p>\n<h3 style=\"text-align: center;\">Get <em>Swimming World Magazine<\/em> and <em>Swimming World Biweekly<\/em> FREE When You<br \/>\n<a href=\"https:\/\/shop.swimmingworld.com\/collections\/donation-options\" target=\"_blank\" rel=\"noopener noreferrer\" data-saferedirecturl=\"https:\/\/www.google.com\/url?hl=en&amp;q=https:\/\/www.swimmingworldmagazine.com\/news\/product-category\/ishof-membership\/&amp;source=gmail&amp;ust=1522345712821000&amp;usg=AFQjCNGfwbLD2OaI21g28efcR0DZZlQSOQ\"><span style=\"color: #0000ff;\">Become A Member of the International Swimming Hall of Fame<\/span><\/a><\/h3>\n<h3 style=\"text-align: center;\">Want More?
