Details and patient eligibility

About

Young, healthy elite boxers ≥ 18 years old are recruited. Prior to, and immediately after a competitive boxing bout over 3x2 or 3x3 minutes, blood samples are drawn. Boxers are randomized to intervention or control management by 1:1 allocation prior to baseline testing. After the initial post-fight blood sample is drawn and symptom rating using the sports concussion assessment tool-5 (SCAT-5) has been collected, the boxers receive either acute selective head-and-neck cooling for 45 min, or routine post-fight management. The number of head impacts are counted in all boxers on match video recordings. In both groups, blood samples are drawn 45 minutes after the initial post-bout blood sample, as well as 3 and 6 days post-fight.
