■为了研究16周太极拳练习对力量的影响,触感,动觉,不同年龄组老年人的静态姿势控制。
■这是一项准实验研究。13名年龄在60-69岁(60-69岁)的参与者,11岁70-79岁(70-79岁),年龄在80-89岁(80-89岁)的13人完成了16周的24种形式的太极拳练习。他们的脚踝和臀部峰值扭矩,触感,脚踝和膝盖的运动感觉,在练习前(第0周)和练习后(第17周)测量压力中心的均方根(Cop-RMS)。
■80-89年显示踝关节足底/背屈和髋关节外展峰值扭矩较少(p=0.003,p<0.001,p=0.001),足底/背屈运动感觉(p<0.001,p=0.002)大于60-69yr和70-79yr。较大的踝足底/背屈和髋关节外展扭矩(p=0.011,p<0.001,p=0.045),改善足弓和脚跟触感(p=0.040,p=0.009),在第17周观察到下膝屈曲/伸展运动感觉(p<0.001,p=0.044)。第5跖骨头颅触觉的显著组*练习交互(p=0.027),足底/背屈运动感觉(p<0.001,p=0.004),仅在80-89年中,中外侧方向的CoP-RMS(p=0.047)在第17周表现出更大的改善。
■太极拳练习增加力量,触感,动觉,和老年人的静态姿势控制。太极拳练习提高触觉,运动感觉,和静态姿势控制在80岁以上的老年人中,他们的力量和运动感觉比年轻人差。太极拳练习为80岁以上的人提供了一种安全的锻炼选择,以鼓励改善感觉运动控制。
UNASSIGNED: To investigate the effect of a 16-week Tai Chi practice on strength, tactile sensation, kinesthesia, and static postural control among older adults of different age groups.
UNASSIGNED: This is a quasi-experimental study. Thirteen participants aged 60-69 years (60-69yr), 11 aged 70-79 years (70-79yr), and 13 aged 80-89 years (80-89yr) completed 16 weeks of 24-form Tai Chi practice. Their ankle and hip peak torque, tactile sensation, ankle and knee kinesthesia, and the root mean square of the center of pressure (Cop-RMS) were measured before (week 0) and after (week 17) practice.
UNASSIGNED: 80-89yr showed less ankle plantar/dorsiflexion and hip abduction peak torques (p = 0.003, p < 0.001, p = 0.001), and a greater ankle plantar/dorsiflexion kinesthesia (p < 0.001, p = 0.002) than 60-69yr and 70-79yr. Greater ankle plantar/dorsiflexion and hip abduction torques (p = 0.011, p < 0.001, p = 0.045), improved arch and heel tactile sensation (p = 0.040, p = 0.009), and lower knee flexion/extension kinesthesia (p < 0.001, p = 0.044) were observed at week 17. The significant group*practice interaction for the fifth metatarsal head tactile sensation (p = 0.027), ankle plantar/dorsiflexion kinesthesia (p < 0.001, p = 0.004), and the CoP-RMS in the mediolateral direction (p = 0.047) only in 80-89yr revealed greater improvement at week 17.
UNASSIGNED: Tai Chi practice increased strength, tactile sensation, kinesthesia, and static postural control among older adults. Tai Chi practice improved tactile, kinesthesia sensations, and static postural control among older adults over 80, who presented with worse strength and kinesthesia than their younger counterparts. Tai Chi practice offers a safe exercise option for those aged over 80 to encourage improvements in sensorimotor control.
