Selective Head-and-neck Cooling on Biomarker Levels and Symptom Rating Following a Boxing Bout

Selective Head-and-neck Cooling on Biomarker Levels and Symptom Rating Following a Boxing Bout- Protocol for an Exploratory Randomized Trial

Sponsor

Region Skane

Enrollment

40 participants

Start Date

Nov 2, 2021

Study Type

INTERVENTIONAL

Conditions

Repetitive Head ImpactSelective Head and Neck Cooling

Summary

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.
