太极柔力球运动对老年女性血清雌激素、肌肉力量及认知功能的影响

Effects of Taiji Ball on the Estrogen,Muscle Strength and Cognitive Function of the Aging Women

目的:通过分析太极柔力球练习对老年女性血清雌激素、肌肉力量、手臂稳定性、光辨别反应时、长时及瞬时记忆保持量的影响,探讨太极柔力球运动提高老年女性肌肉力量及认知功能的可行性。方法:选取老年女性29人,分为对照组(14人)和锻炼组(15人),对两组血清雌二醇、左右手握力、红绿光辨别反应时、手臂稳定性及长时、瞬时记忆保持量等各项指标进行比较分析。结果:与对照组比较,老年女性太极柔力球锻炼组的血清雌二醇(76.85±15.36pmol/L;P<0.01)、右手握力(278.36±52.36N;P<0.01)、红绿光辨别反应时(0.42±0.15s;0.60±0.21s;P<0.01,P<0.05)、右手臂稳定性(3.65±0.52mm;P<0.01)、长时记忆保持量(0.55±0.09;P<0.05)及瞬时记忆保持量(0.62±0.15;P<0.05)差异均有显著性;左手握力(225.69±18.67N)及左手臂稳定性(5.3±0.99mm)较对照组增高,但无显著性差异(P>0.05)。结论:太极柔力球练习可增高老年女性的血清雌二醇水平,对提高老年女性的肌肉力量及认知功能具有积极作用,值得大力推广。

Objective：By analyzing the effects of the Taiji ball exercise on the serum estrogen,muscle strength,arm stability,optical discriminative reaction time,long-term and immediate memory keeping of the aging women,this paper probed into the feasibility of applying the Taiji ball exercise to enhance the muscle strength and cognitive function.Methods：29 aging women were compared in terms of the serum estrogen,muscle strength,arm stability,optical discriminative reaction time,long-term and immediate memory keeping.15 aging women who performed Taiji ball exercise for years as the exercise group and 14 aging women who did not take part in Taiji ball exercise as the control group.Results：Com[pared with the control group,the serum estrogen（76.85±15.36 pmol/L;P0.01）,right hand grip strength（278.36±52.36N;P0.01）,right arm stability（3.65±0.52;P0.01）,red and green optical discriminative reaction time（0.42±0.15s;0.60±0.21s;P0.01,P0.05）,long-term memory（0.55±0.09;P0.05） and immediate memory（0.62±0.15;P0.05）were significantly different in the exercise group,however left hand grip strength and arm stability were enhanced in the exercise group but they were not significant difference（P0.05）.Conclusion：Taiji ball exercise may increase the serum estrogen level and played an important role in enhancing muscle strength and cognitive functions of the aging women,so the Taiji ball is worth promotion.
