Tabatha Hartshorn and Kendra Graham \u2014 themselves both former competitive swimmers and coaches \u2014 compare the muscle activation in swimmers with and without shoulder pain through the catch and pull of the freestyle stroke, during which a swimmer reaches above the head and then pulls with a bent elbow through the water until the arm is parallel with the body.<\/p>\n<div class=\"oembed oembed-youtube-com\" style=\"\" data-url=\"https:\/\/www.youtube.com\/watch?v=SilcPw_K_sM&amp;feature=youtu.be\"><iframe loading=\"lazy\" title=\"Swim study   VR lab\" width=\"1000\" height=\"563\" src=\"https:\/\/www.youtube.com\/embed\/SilcPw_K_sM?feature=oembed\" frameborder=\"0\" allow=\"accelerometer; autoplay; clipboard-write; encrypted-media; gyroscope; picture-in-picture\" allowfullscreen><\/iframe><\/div>\n<p>\u201cWe are looking at swimmers\u2019 shoulders to see if there is any differences between swimmers that have reported to have pain or not have pain in their shoulders,\u201d Hartshorn said, noting shoulder pain is often dismissed as merely an overuse injury. \u201cAs past swimmers, we both have not only experienced it ourselves, but have seen other athletes experience shoulder pain and not really have a reason why, or it just gets written off. We feel like there\u2019s probably a why behind the pain, and we want to know why.\u201d<\/p>\n<p>In the <a href=\"https:\/\/web.uri.edu\/chs\/\">College of Health Science<\/a>\u2019s new Biomechanics Laboratory in Independence Square, which is equipped with virtual reality motion capture technology, the students will apply EMG electrodes to the bodies of 20 swimmers, 10 with shoulder pain and 10 without. While the swimmers perform the \u201ccatch and pull\u201d freestyle swimming motion on a modified weight bench in the lab, their movements are recorded with motion capture cameras. Muscle patterns are analyzed through electromyography on the upper and middle trapezius muscles, the biceps brachii, and triceps brachii while the athlete is performing resistance exercises and simulated ergometer swimming exercises.<\/p>\n<p>The motion capture cameras create a skeletal image of the swimmers on a computer monitor, allowing researchers to monitor the arm movement and the level of stress placed on the muscles throughout the swimming stroke. They can see what position a swimmer is in when the muscles are activated and if that\u2019s the motion they expect, or if the athlete\u2019s motion is altered due to the pain he or she is feeling, allowing them to pinpoint damage and the exact motion that causes it.<\/p>\n<p>\u201cWe started the study because we were both interested in swimmers\u2019 injuries; we noticed there were a ton of shoulder problems in ourselves and our peers, and we wanted to learn why,\u201d Graham said. \u201cWe hope by doing this research, we may be able to find a muscular or kinematic reason so future swimmers and coaches will have something to use in the weight room or in practice to prevent and treat their injuries.\u201d<\/p>\n","protected":false},"excerpt":{"rendered":"<p>KINGSTON, R.I. \u2014 March 4, 2021 \u2014 Sports such as swimming, tennis and baseball, which involve repetitive overhead arm motions, often lead to imbalances and injury within the muscles surrounding the scapular and shoulder joints, often leading to chronic shoulder pain, especially for swimmers, about 91 percent of whom experience chronic shoulder pain.
