BeFAST or BeSTRONG: Brain Change After Fun Athletic Sports-skill Training or Brain Change After Strength TRaining Focusing ON Gait

The motor learning (ML)-based gait-related training program is designed to improve advanced gross motor skills and athleticism. It will involve 45-min sessions twice to three times weekly over 6 weeks for a total of 16 active sessions. A maximum of 7 weeks will be permitted. Each session will consist of 35-min of active training along with a 10-min active warm-up/cool-down that incorporates ML. Children will be given a 3- to 5-min mental motor imagery script to practice on days when they do not have active training sessions. The total number of sessions (combined training/home imagery) will be five per week.
