摘要
The purpose of the present study was to examine the effects of a 24-week Tai Chi exercise intervention on balance and other physical changes such as flexibility and reaction time(RT)among healthy older males.Methods:Thirty-eight male subjects aged 55-65 years without prior Tai Chi experience were recruited from a local community in Shanghai,China.A 60-min Tal Chi exercise session was performed three times a week for 24 weeks.Changes in RT,sit-and-reach flexibility and balance (static balance with eyes open and closed respectively)were measured before and after the Tal Chi intervention.Results:After the 24-week Tai Chi intervention,the choice RT(P ＜ 0.05)decreased,and sit-and-reach flexibility improved (P ＜ 0.01)over the pre-test(7.8 ±6.2 vs.7.1 ±3.0cm).Sway length,area,X-axis deviation amplitude and Y-axis deviation amplitude performance decreased significantly after the intervention with a double-foot stance with eyes open(P ＜ 0.05).Sway length,area and average sway speed showed a statistically significant decrease after the intervention with the double-foot stance with eyes closed.In the single-footstance with eyes open condition,sway length and average swayspeed showed a statistically significant decrease(P＜0.05).Conclusion:The 24-week Tai Chi exercise intervention had a positive influence on balance control in older males.Copyright(C)2012,Shanghai University of Sport.Production and hosting by Elsevier B.V.All rights reserved.

Methods:Thirty-eight male subjects aged 55—65 years without prior Tai Chi experience were recruited from a local community in Shanghai, China.A 60-min Tai Chi exercise session was performed three times a week for 24 weeks.Changes in RT,sit-and-reach flexibility and balance (static balance with eyes open and closed respectively) were measured before and after the Tai Chi intervention. Results:After the 24-week Tai Chi intervention,the choice RT(p < 0.05) decreased,and sit-and-reach flexibility improved(p < 0.01) over the pre-test(7.8±6.2 vs.7.1±3.0 cm).Sway length,area,X-axis deviation amplitude and K-axis deviation amplitude performance decreased significantly after the intervention with a double-foot stance with eyes open(p < 0.05).Sway length,area and average sway speed showed a statistically significant decrease after the intervention with the double-foot stance with eyes closed.In the single-foot stance with eyes open condition,sway length and average sway speed showed a statistically significant decrease(p < 0.05). Conclusion:The 24-week Tai Chi exercise intervention had a positive influence on balance control in older males.
