Abstract

Background: Computerized neurocognitive testing is part of the recommended multi-faceted approach to SRC assessment. Prior research has suggested that maximal exertion negatively effects CNT test scores. Purpose: To identify the appropriate timing of the administration of CNT following maximal exertion in healthy college-aged student athletes. Study Design: Prospective, random cross-over, repeated measures design. Methods: Week one participants fill out intake forms and then complete a baseline ImPACT test. The following three weeks, individuals were administered a VO2 max cycle ergometer test. Following the test participants will rest for <5 (immediate), 15, or 30 minutes before re-taking ImPACT. Results: Immediately following maximal exertion, negative composite scores, relative to baseline, were seen in 1/6 for verbal memory, 2/6 for visual memory, 2/6 participants for visual motor, and 2/6 participants for reaction time. Post-test 15 minutes decrements were seen for 0/6 participants for verbal memory, 2/6 participants for visual memory, 1/6 participants for visual motor, and 2/6 participants for reaction time. Post-test 30 minutes decrements were seen for 1/6 participants for verbal memory, 1/6 participants for visual memory, 1/6 participants for visual memory, and 3/6 participants for reaction time. Discussion: Time constraints, schedule conflicts, and participant availability was a major barrier to recruitment efforts. A small pilot study was conducted. Results from this pilot were not consistent with previous research. Mode of exercise, randomization of baseline trials, and better participant compliance should be addressed before moving forward.
