The executive functioning aspect of cognition was evaluated during graded exercise in Reserve Officers’ Training Corps cadets. Executive function declined at exercise intensities of ≥80% of heart rate reserve. The decline in executive function was coupled with declines in the oxygenation of the prefrontal cortex, the brain region responsible for executive functioning. These data define the executive function-exercise intensity relationship and provide evidence supporting the reticular activation hypofrontality theory as a model of cognitive change.

ABSTRACT Introduction Military members’ knowledge of concussion signs and symptoms may be critical to appropriate concussion identification and health-seeking behavior, particularly for those in leadership roles. The current study aimed to characterize concussion knowledge and attitudes among future military officers undergoing U.S.-based Reserve Officers’ Training Corps (ROTC) training. Materials and Methods Army and Air Force ROTC cadets at 2 large, public universities were utilized for a survey-based observational study. The study was approved by the institutional review board at both university research sites. Cadets completed a modified Rosenbaum Concussion Knowledge and Attitude Survey to obtain cadets’ Concussion Knowledge Index and Concussion Attitude Index, where higher scores are preferable. Cadets’ concussion knowledge and attitudes were characterized via descriptive statistics. Results Cadets (n = 110) had a mean Concussion Knowledge Index of 18.8 ± 3.2 (range = 9–23, out of 25). Potentially detrimental misconceptions included: belief that typically concussion symptoms no longer persist after 10 days (79.1%) and brain imaging shows visible physical damage following concussion (74.5%). Mean Concussion Attitude Index was 60.6 ± 7.4 (range = 46–75, out of 75). In general, cadets reported higher agreement with safe concussion behavior than what they believe peers would report. Conclusions Cadets were found to have a high concussion knowledge, yet common misconceptions remained. Cadets consistently reported safe choices but were less sure that peers felt similarly; future investigations should evaluate ROTC concussion social norms and education should note peers’ beliefs supporting safe concussion attitudes.

This research examined the effects of pure and crossed dextrality on the marksmanship scores of cadets in the Reserve Officers Training Corps at their respective institutions. 34 male, right-handed (dextral) subjects (M age = 21.5 yr.) were classified on the basis of eyedness. During summer advanced training camp, subjects fired M-16A1 rifles for marksmanship qualifying scores (score range 0 to 40). Of the 34 subjects, 17 were classified as pure dextrals (right-hand, right-eye), while the other 17 were labeled crossed dextrals (right-hand, left-eye). The mean difference between the two groups was significant, suggesting that pure dextrals are better marksmen than crossed dextrals early in training. Also, the interrelation of eyedness and handedness on marksmanship scores is important but has been largely ignored.
