Reduced feelings of regret and enhanced fronto-striatal connectivity in elders with long-term Tai Chi experience.

ABSTRACT: The current study investigates how long-term Tai Chi experience affects the neural and emotional response to regret in elders. Participants perform the sequential risk-taking task while undergoing functional magnetic resonance imaging (fMRI) scanning. In the task, participants opened a series of boxes consecutively and decided when to stop. Each box contained a reward, except for one which contained a devil. If the devil was revealed, then this served to zero the participant's gain in that trial. Once stopped, participant's gains and missed chances were revealed. Behaviorally, the Tai Chi group showed less regret, reduced risk taking, higher levels of nonjudgment of inner experience and less emotional sensitivity to outcome. fMRI results showed that the Tai Chi group demonstrated stronger fronto-striatal functional connectivity in trials with numerous missed chances. The nonjudgment of inner experience mediated the impact of fronto-striatal functional connectivity on Tai Chi practitioners' emotional sensitivity to outcome. These results highlight that long-term Tai Chi exercise may be effective in alleviating feelings of regret in elders by promoting reduced judgment of inner experience and enhanced emotion regulation through the strengthening of fronto-striatal functional connectivity.

Project description:In order to maintain stable upright stance, the postural control system must account for the continuous perturbations to the body's center-of-mass including those caused by spontaneous respiration. Both aging and disease increase "posturo-respiratory synchronization;" which reflects the degree to which respiration affects postural sway fluctuations over time. Tai Chi training emphasizes the coordination of respiration and bodily movements and may therefore optimize the functional interaction between these two systems. The purpose of the project was to examine the effect of Tai Chi training on the interaction between respiration and postural control in older adults. We hypothesized that Tai Chi training would improve the ability of the postural control system to compensate for respiratory perturbations and thus, reduce posturo-respiratory synchronization. Participants were recruited from supportive housing facilities and randomized to a 12-week Tai Chi intervention (n=28; 86 ± 5 yrs) or educational-control program (n=34, 85 ± 6 yrs). Standing postural sway and respiration were simultaneously recorded with a force plate and respiratory belt under eyes-open and eyes-closed conditions. Posturo-respiratory synchronization was determined by quantifying the variation of the phase relationship between the dominant oscillatory mode of respiration and corresponding oscillations within postural sway. Groups were similar in age, gender distribution, height, body mass, and intervention compliance. Neither intervention altered average sway speed, sway magnitude or respiratory rate. As compared to the education-control group, however, Tai Chi training reduced posturo-respiratory synchronization when standing with eyes open or closed (p<0.001). Tai Chi training did not affect traditional parameters of standing postural control or respiration, yet reduced the coupling between respiration and postural control. The beneficial effects of Tai Chi training may therefore stem in part from optimization of this multi-system interaction.

Project description:Background:The newly compiled Bafa Wubu of Tai Chi (Eight Methods and Five Footworks) is a fitness routine that has been developed in accordance with the appeal of the General Administration of Sport of China and promoted both in China and abroad. This paper aims to compare the differences in energy consumption and related parameters between the two types of Tai Chi. Methods:A total of 60 healthy participants were recruited; 37 males (aged 37.4?±?10.4?years) and 23 females (aged 31.9?±?12.8?years). The maximal exercise capacity of participants was measured at baseline. Then, they received Tai Chi training for 12-week and their energy metabolism was measured dynamically. Results:A set of the Bafa Wubu of Tai Chi requires approximately 3?min, while a set of 24 form simplified Tai Chi approximately 5?min and 40?s. The average oxygen uptake/kg (VO2/kg, 10.8?±?2.52?ml/kg/min vs. 12.9?±?2.59?ml/kg/min, P?=?0.000), the highest VO2/kg (19.3?±?6.03?ml/kg/min vs. 24.1?±?7.50?ml/kg/min, p?=?0.000, the average metabolic equivalent (METs,2.3?±?0.16 METs vs. 3.2?±?0.14 METs, p?=?0.000), the highest oxygen pulse (VO2/HR, 11.1?±?0.99?ml vs. 13.9?±?0.93?ml, p?=?0.000) and rate of perceived exertion (RPE, 10.7?±?0.70 vs. 1.3?±?0.62, p?=?0.000) gained immediately after Bafa Wubu of Tai Chi exercise were significantly lower than those in 24 form simplified Tai Chi; heart rate recovery (HRR,1.5?±?0.41 vs. 1.3?±?0.45, p?=?0.008) at 1?min after the practice was significantly higher than after the 24 form simplified Tai Chi. Meanwhile, the average heart rate (HR, 104.1?±?11.41?bpm vs. 105.7?±?9.68?bpm, p?=?0.696) and the highest respiratory quotient (RQ, 1.0?±?0.06 vs. 0.9?±?0.09, p?=?0.643) were not significantly different. The intensity of Tai Chi was described as the highest oxygen uptake of the participants when they performed the Tai Chi divided by their individual maximal oxygen uptake. Tai Chi intensity during Bafa Wubu of Tai Chi (50%?±?11.7% vs. 64%?±?12.5%) was significantly lower than during 24 form simplified Tai Chi. Conclusion:The newly compiled Bafa Wubu of Tai Chi is characterized by lower energy consumption than 24 form simplified Tai Chi.
