Results of brain activity.

Note. * Significant if p < 0.05. There were eight transmitter optodes and two receiver optodes, which compose of 8 channels covering the dorsolateral prefrontal cortex. The CH1, CH2, CH5 and CH6 lie in the right dorsolateral prefrontal cortex (dlPFC), while the CH3, CH4, CH7 and CH8 lie in the left dlPFC. Rugby (group) denotes GameHIIT group, and fitness (group) denotes GameSAE group.

(A) During pre-test, the brain activation of participants at CH1 while performing Wisconsin Card Sorting Test (WCST) was significantly higher than baseline. During post-test, the brain activation of participants at CH2 and CH7 while performing the Colour-Word Stroop Test (CWST) was significantly higher than baseline. (B) In the GameHIIT group, the brain activation of participants during post-test at CH3 and CH7 was significantly higher than that during pre-test, while the difference did not exist in the other groups. (C) During pre-test, the brain activation of participants in the GameHIIT group at CH3 while performing Tower of London Test (ToLT) was significantly higher than that in the control group.
