The hamstring strain is one of the most prevalent sports injuries and lots of efforts are made to reduce their incidence.<\/span>\n\n<span style=\"font-weight: 400;\">Askling et al observed two main mechanisms of injury in elite soccer players which were either stretching such as during a glide tackle or high kick AND spriting-type injuries occurring during high speed running.\u00a0<\/span>\n\n<span style=\"font-weight: 400;\">What they found was that stretching type injury affected mostly the Semimembranosus und sprinting type the long head of the biceps femoris.\u00a0<\/span>\n\n<span style=\"font-weight: 400;\">When they compared their rehab protocol focusing on load during lengthening, it appeared superior to conventional protocols. So let\u2019s dive into the exercises:<\/span>\n<div class=\"embed-container\">\n\n[embed]https:\/\/www.youtube.com\/watch?v=D6bGLfCk4QU[\/embed]\n\n<\/div>\n<b>1) The Extender<\/b>\n\n<span style=\"font-weight: 400;\">Hold and stabilize the thigh of the injured leg with the hip flexed approximately 90\u00b0.\nP<\/span><span style=\"font-weight: 400;\">erform slow knee extensions to a point just before pain is felt.\n<\/span><span style=\"font-weight: 400;\">Twice every day, three sets with 12 repetitions\u00a0<\/span>\n\n<b>2) The Diver<\/b>\n\n<span style=\"font-weight: 400;\">Stance leg with a slightly flexed knee. <\/span><span style=\"font-weight: 400;\">Swing leg bent to 90\u00b0 knee flexion.\n<\/span><span style=\"font-weight: 400;\">Perform a dive forward by flexing at the hip and extend arms forward.\n<\/span><span style=\"font-weight: 400;\">Start slow in the beginning and increase speed gradually once every other day, 3x6<\/span>\n\n<b>3) The Glider<\/b>\n\n<b><\/b><span style=\"font-weight: 400;\">Start from a position with an upright trunk. O<\/span><span style=\"font-weight: 400;\">ne hand holding on to support and legs slightly split.\n<\/span><span style=\"font-weight: 400;\">Bodyweight should be on the heel of the injured leg with approximately 10\u201320\u00b0 flexion in the knee.\n<\/span><span style=\"font-weight: 400;\">The motion is started by gliding backward on the other leg and stopped before pain is reached. The movement back to the starting position should be performed with the help of both arms, not using the injured leg. Progression is achieved by increasing the gliding distance and performing the exercise faster.\nOnce every third day, three sets with four repetitions <\/span>\n\nIf you are further in the rehab process, you might want to progress to more demanding exercises tackling all muscles and heads of the hamstrings.\nHere are our top <a href=\"https:\/\/www.physiotutors.com\/wiki\/best-hamstring-exercises\/\" target=\"_blank\" rel=\"noopener\">4 hamstring exercises<\/a>.\n\n&nbsp;\n"}},{"acf_fc_layout":"content-content","section_options":{"vertical_alignment":"top","column_right_box":false,"column_left_width":"col-12 col-lg-4 offset"},"column_left":{"content_editor":"<h4>References<\/h4>"},"column_right":{"content_editor":"<a href=\"https:\/\/bjsm.bmj.com\/content\/47\/15\/953\" target=\"_blank\" rel=\"noopener\">Askling CM, Tengvar M, Thorstensson A.
