Left: Effects of Tai Chi training on putamen gray matter volume (GMV). There were significant differences within the group in the left putamen clusters after training (peak coordinates = − 26, − 15, 9, voxel number = 166, P = 0.020 < 0.05 after FWE correction). Right: The results of the linear mixed models (LMM) analysis in the region showed a significant group effect by the time interaction on the putamen GMV (P < 0.001). The putamen GMV in the experimental group decreased significantly after training (P = 0.001), but the change was not significant in the control group. Each data point represents the value of one participant. Next to each arrow is the confidence interval (CI) for each effect. *P < 0.05. Notes: GMV: gray matter volume
