0concussion_1.jpgThe imbedded sensors that Kevin Guskiewicz and his researchers used sent data to computers on the sideline that recorded impacts the players sustained. 15899concussion_2.jpgUsing the HITS system, made by Simbex Inc., UNC researchers recorded hits under 60g that resulted in concussions, and hits well over 100g that did not, challenging the suggestion for a 70-75g threshold. 31802concussion_3.jpgThe sensors fit snuggly into the helmets and measured the impact of hits in g-forces and the directional force Ð linear or rotational Ð to the head. Researchers found no significant difference in outcomes between linear and rotational forces, contrary to current beliefs. 47701concussion_4.jpgAfter one player sustained two concussions, graduate student Jason Mihalik (left), Kevin Guskiewicz and the football staff used video from the studies to help the player correct his blocking technique, which prevented a third concussion after a big hit against rival N. C. State University. version517creditscredits hereabstractabstract here...header_headlineheadline here ...header_font_hex000000header_hexFFFFFFheader_height30body_hex000000body_frame_hex000000controls_hex333333controls_styledefaultfooter_hexFFFFFFfooter_font_hex000000footer_height15htmlbg_hexFFFFFFplayer_styledefaultautoStartfalseautoShowCaptionsfalsedisplay_sizesfalsedisplay_headlinetruedisplay_footertrueshowCreditstrueshowCaptionstrueembed_stylefalsecentertrueheader_headline_fontArialcaption_font_faceArialcaption_font_size11footer_font_faceVerdanafooter_font_size9scrub_previewfalseshow_volumefalsetransition_typecrossfadetransition_time1show_thumbnailstrue1197080459184Initial import
