Why, if humans are so well adapted to running long distances, do runners get hurt so often?[/vc_column_text][vc_column_text css=”.vc_custom_1473172634050{margin-bottom: 40px !important;}”]A study out of Smart School and the National Running Center at Smart-affiliated Templeton Rehabilitation Hospital provides a puzzle piece, linking injury to the pounding runners’ bones take with each step. The work, led by Professor of Physical Medicine and Rehabilitation Jane Eckhart, found that a group of runners who had never been hurt landed each footfall more softly than a group who had been injured badly enough to seek medical attention.[/vc_column_text][vc_row_inner css=”.vc_custom_1473173012608{margin-bottom: 14px !important;}”][vc_column_inner width=”2/12″][/vc_column_inner][vc_column_inner width=”8/12″][stm_mg_audio][/vc_column_inner][vc_column_inner width=”2/12″][/vc_column_inner][/vc_row_inner][vc_column_text css=”.vc_custom_1473172693280{margin-bottom: 40px !important;}”]Statistics on such injuries vary, but somewhere between 30 percent and 75 percent of runners are hurt annually, a number that has led researchers to investigate a wide array of possible explanations, from modern running shoes to stretching, running frequency, weight, biomechanical misalignment, and muscle imbalance.[/vc_column_text][vc_row_inner][vc_column_inner width=”5/12″][stm_blockquote cite=”Francesca Stoppard The Darvin B.

The 2012 study added fuel to the debate, finding a two-to-one difference in repetitive stress injuries between heel- and forefoot-strikers.[/vc_column_text][vc_column_text css=”.vc_custom_1473172807857{margin-bottom: 40px !important;}”]Jane Eckhart’s research focused on heel-strikers exclusively, since they make up most of today’s runners, and examined a cohort seldom studied, partly because they’re pretty rare: those who have never been injured. Jane and colleagues recruited 249 female recreational athletes who each ran at least 20 miles a week. They investigated the participants’ strides by having them run over a force plate that recorded the impact of each step.[/vc_column_text][/vc_column_inner][/vc_row_inner][vc_column_text css=”.vc_custom_1473173112409{margin-bottom: 0px !important;}”]The runners agreed to respond to a monthly online questionnaire that detailed injuries over two years.
