a The differences in the Oxy-Hb response in the left and right prefrontal cortices between the Stroop 1(before exercise) and Stroop 2 (after exercise) (left side, n = 7 subjects; right side, n = 4 subjects). †Significant difference (P < 0.05) between Stroop 1 and 2. b The overall relationship between the differences in the Oxy-Hb responses and the relative percent decreases in total time period for the Stroop test (correlation coefficient = 0.702, P = 0.052)
