Objective: To investigate the effects of brain endurance training on improving motor skill learning in adolescents with mild mental fatigue. Methods: Fifty-eight adolescents experiencing mild mental fatigue were recruited. A 6-week training program was conducted using a 2 (BET group, control group) × 2 (pre- and post-Stroop task) × 3 (0, 3, 6 weeks) mixed-design experimental design. Assessments included basketball free throws, the Visual Analog Scale (VAS-MF), the 3-minute Psychomotor Vigilance Test (PVT-B), the Borg Rating of Perceived Exertion (RPE) to assess performance before and after a 30-minute Stroop task.

During training, the BET group completed a 20-minute 2-back task \[28\]; after a 5-minute break, they performed free-throw-related physical and technical training. The training content, intensity, and workload were identical for both groups, and the presentation timing and intervals of the 2-back task stimuli were adjusted every two weeks \[18\]. During testing, both the BET group and the control group completed 20 free-throw attempts and a 1-minute free-throw test \[29\] before and after the 30-minute Stroop task, and underwent PVT-B, VAS-MF, and RPE assessments.
The BET group and the control group underwent the same physical and technical training related to free throws; the training content, intensity, and workload were identical for both groups. While the BET group performed cognitive tasks, the control group rested in place. The presentation timing and intervals of the 2-back task stimuli were adjusted every two weeks \[18\]. During testing, both the BET group and the control group completed 20 free-throw trials and a 1-minute free-throw test \[29\] before and after the 30-minute Stroop task, and underwent PVT-B, VAS-MF, and RPE assessments.
