Repetitive head impact exposure (RHIE) during contact sports (CS) might have potentially long-term neurological effects. We evaluated the effect of sport, time, and their interaction on local and global functional connectivity density (FCD) as measured using an advanced multiband multi-echo EPI sequence in CS and non-contact sport (NCS) middle school and high school athletes. Significant effects of sport and the interaction between sport and time on both local and global FCD were detected, which might suggest functional connections alterations due to contact sport participation.
