Fig. 6. The study involved 59 adolescent male students who were divided into control (n = 20), sneaker (n = 19), and barefoot (n = 20) groups.
The barefoot and sneaker groups performed a 40-min walking exercise four times a week for 12 weeks during morning physical activity time, while the control group performed self-study. Electroencephalogram (EEG) and brain activity variables were measured before and after the exercise program. After 12 weeks, the barefoot group showed a significant decrease in gamma and H-beta waves and a significant increase in sensorimotor rhythm (SMR) and alpha waves. The control group showed a significant decrease in SMR waves and an increase in theta waves. The sneaker group showed a significant decrease in only SMR waves. In the resting state with eyes open, the barefoot group showed a significant increase in H-beta, M-beta, SMR, and alpha waves. In addition, the barefoot group showed a significant increase in cognitive speed and concentration, and a significant decrease in brain stress. Taken together, barefoot walking can effectively improve cognitive performance in adolescents, as evidenced by significant changes in EEG activity.
