Difference in gray matter density between the Baduanjin (BDJ) group and the brisk walking (BWK) group before and after the intervention. C: Brain areas with increased gray matter volume in the BDJ group compared with the BWK group: Right frontal lobe, right precentral Gyrus, right supraital Occipital gyrus, right occipital middle gyrus, right frontal lobe; D: compared with the BWK group, there was a decrease in gray matter volume in the BDJ group before and after the intervention: right cerebellar posterior lobe, right superior temporal gyrus, right occipital lobe, right precuneus lobe, left superior occipital gyrus, left superior frontal gyrus.
