During human motor control, the three pathways of motor control coordinate to complete human response and inhibition control, so whether different types of motor skills training will affect the three pathways of motor control is the main question in this study. Magnetic resonance imaging was combined with behavioural evaluation to analyse the effects of different special training sessions on the motor control network of the frontal lobe and basal ganglia and to explore the role of the central nervous system in the regulation of motor behaviour. A Stop-signal paradigm was used to measure reaction and inhibition capacity, functional magnetic resonance imaging was used for whole brain scanning, and resting state data were collected. Compared to the control group, the competitive aerobics athletes had better reflexes while the soccer players had both better reflexes and inhibitory control. Furthermore, we found that training in the two sets of skills resulted in significant differences in different resting state brain function parameters compared with the control group. Additionally, there were significant differences among the three groups in the direct and indirect pathways of motor control in terms of functional connectivity. Open skill training may improve reaction ability while closed skill training improve both reaction and inhibition ability. These results suggest that the strength of the functional connectivity between the right inferior frontal gyrus and the left putamen may be a key to improving the inhibitory, and the left supplementary motor area- bilateral thalamic loop may play an inhibitory role in motor control.

Abstract. Resting-state functional magnetic resonance imaging (fMRI) studies demonstrate that long-term exercise or dance training may cause changes in brain structure and function. However, the changes of neurofunction in the long-term practitioners of Chinese classical dance are still unclear. The purpose of the study is to explore the neurofunctional alterations associated with long-term Chinese classical dance training. Thirty female college students were selected, 15 students majoring in Chinese classical dance (average training years = 9.73 ± 1.75 years) and 15 education-matched non-dancer students with no previous experience of regular dance training. In this cross-sectional design, the resting-state fMRI data were acquired only once to observe the structural and functional changes of the brain. Compared with non-dancers, professional dancers had no significant difference in the total volume of whole brain, gray matter, white matter, and cerebrospinal fluid. While in professional dancers, we found increased amplitude of low-frequency fluctuation (ALFF) in the left superior occipital gyrus, right Cuneus, and left calcarine fissure and surrounding cortex (Calcarine); increased fractional ALFF and regional homogeneity in the right Calcarine, indicating the increase of spontaneous brain activity in these brain areas. Since these brain areas are related to visual cognitive function, the results suggest that long-term Chinese classical dance training is associated with increased spontaneous regional brain activity in the visual areas. This may be closely related to the specific characteristics of Chinese classical dance and long-term professional training.
