【摘要】：目的:本研究采用等速肌力测试对郑氏三体式站桩后大腿肌肉力量的变化进行分析,明确郑氏三体式站桩训练对人体下肢肌力和跌倒的影响,为预防老年人跌倒以及提高老年人下肢肌力提供理论依据和科学指导,从而为家庭和社会减轻负担。方法:对40名60-69岁健康的老年女性进行为期两个月的郑氏三体式站桩干预后进行等速肌力测试、30s连续坐椅实验和跌倒风险的测评。结果:1.受试者在经过为期两个月的郑氏三体式站桩的运动干预后,左右两侧腿的峰力矩值、大腿所做的总功、平均功率都呈增加的趋势,差异显著(P0.05),说明在郑氏三体式站桩运动干预后受试者的肌肉力量、肌肉功能在提高;2.在郑氏三体式站桩之后,受试者左右两侧大腿伸肌的峰力矩角度增加,效果显著(P0.05),说明两侧腿的伸肌肌肉收缩能力有所增加;但是左右屈肌无明显变化;3.在郑氏三体式站桩运动干预前受试者膝关节不稳定,容易发生跌倒,在实验后效果显著(P0.05)受试者屈伸肌峰力矩比值左右腿都接近于60%,说明受试者膝关节稳定性提高,跌倒的危险性降低;4.在进行干预后受试者在30s内所做的起立坐下个数增多,和干预前有显著性差异(P0.05),说明受试者在进行运动干预后下肢的动作能力增强;5.受试者在干预前跌倒指数高于干预后,干预前后跌倒指数差异显著(P0.05),干预后老年人的跌倒指数在降低,说明郑氏三体式站桩对降低老年女性跌倒的风险有一定效果。
[Abstract]:Objective: to analyze the changes of the muscle strength of the thigh after Zheng's trisomy station pile with isokinetic muscle strength test, and to clarify the influence of the training of the trisomy three body pile training on the muscle strength and fall of the lower limbs of the human body, and provide the theoretical basis and scientific guidance for preventing the fall of the elderly and improving the strength of the lower limbs of the aged. Methods: 40 60-69 year old healthy elderly women were tested for two months' tri body post for two months to perform isokinetic muscle strength test, a continuous chair test and a fall risk assessment. Results: 1. subjects were after the exercise after two months of Zheng's tri body pile movement, and the peak torque value of the left and right legs was large. The average power of the leg was increased, the difference was significant (P0.05), indicating that the muscle strength and muscle function of the subjects were improved after the intervention of Zheng's tri body pile movement. 2. after Zheng's trisomy station pile, the peak torque angle of the extensors on the left and right sides of the subjects increased significantly (P0.05), indicating the extension of the legs. The muscle and muscle contraction ability increased, but there was no obvious change in the left and right flexors. 3. before the intervention of Zheng's trisomy platform, the knee joint was unstable and prone to fall. After the experiment, the effect of the flexor and extensor peak torque ratio of the subjects was close to 60% after the experiment (P0.05), indicating the stability of the knee joint and the danger of the fall. There was a decrease in risk; 4. after intervention, the number of people sitting in the 30s increased, and there was a significant difference before intervention (P0.05), indicating that the lower extremity action ability of the subjects increased after the exercise intervention; the fall index of the subjects before intervention was higher than that before the intervention, and the fall index before and after intervention was significant (P0.05), and the intervention was old. The fall index of the aged is decreasing, indicating that Zheng's trisomy style post has some effect on reducing the risk of falling down of old women.
