No results posted yet for this study

Summary

The purpose of this study is to examine the combined effects of hypoxia and a short bout of subconcussive head impacts on neurocognitive and ocular-motor function and plasma expression of brain-derived blood biomarkers.

Conditions

  • Trauma, Brain

Interventions

BEHAVIORAL

Soccer heading

A standardized and reliable soccer heading protocol will be used to induce subconcussive impacts for the experiment. A triaxial accelerometer (Triax Technologies, Norwalk, CT) embedded in a head-band pocket and positioned back of the head to monitor linear and rotational head accelerations. A JUGS soccer machine (JUGS Sports, Tualatin, OR) will be used to simulate a soccer throw-in with a standardized ball speed of 25 mph across all groups. The ball speed is similar to when soccer players make a long throw-in from the sideline to mid-field. Soccer players frequently perform this maneuver during practices and games. Participants will stand approximately 40ft away from the machine to perform the heading. Participants will perform a total of 10 headers at a rate of 1 header per minute and will be instructed to direct the ball back towards the JUGS machine. Previous uses of this soccer heading model have reported an average peak linear acceleration per header of 14.5 to 33.5 g.
