A Comparative Study On The Effects Of Different Items On The "Core Stability" Of Middle - Aged And Aged Women

Object:the aging phenomenon in China is becoming more and more significant, resulting in an increasingly prominent problem of the elderly care. The premise of improving the life quality for the elderly is that the aged generations stay healthy themselves. Soft and slow movement is short for the Chinese soft and slow movement. The special movement has gained much attention as a traditional Chinese fitness and health preserving method with a solid foundation of mass participation. In order to understand the impact of different projects of the soft and slow movement on the health of middle-aged and aged women, in the study, indicators that affect the core stability are tested and compared so as to provide reference for practitioners of the soft and slow movement.Methods:40 middle-aged and aged women are divided into the Tai Chi Group (group A1), Guided Group (group A2), Martial Arts Dance Group(group A3) and Non-Exercise Group (group B),10 people for each group. Test indicators mainly include the maximum isometric muscle strength in the core area, the standing with a single leg with eyes closed and the knee flexor group of isokinetic muscles strength. All data are treated statistically.Results:significant difference were found as follows:1) For the isometric muscle strength in the core area, the front flexion muscle strength in groups A1 and A2 is significantly greater than that in group B; the extensor muscle strength in group Al is greater than that in group A2 and group B; the left dextral muscle strength in group Al is greater than that in groups A2,A3 and B; the right dextral muscle strength in group A1 is greater than that in group A3 and B; the right dextral muscle strength in group A2 is greater than that in group B.2) For those standing with a single leg with eyes closed, as for the left leg, the strength in group A1 and A2 is greater than that in group B; as for the right leg, the strength in group A is greater than that in group B.3) For the peak torque in the equal-speed and centric movement of the knee flexion muscles (angular speed:60 degrees/s), for the left leg flexor muscles, torque in group Al and A2 is greater than that in group B; for the left leg extensor muscles, torque in group A2 and group A3 is greater than that in group B; for the right leg flexor muscles, torque in group A2 and A3 is greater than that in group B; for the right leg extensor muscles, torque in group A is greater than that in group B.4) For the total work in the equal-speed and centric movement of the knee flexion muscles (angular speed:60 degrees/s),work in group A3 is greater than that in group B.Conclusion:1) In projects of the soft and slow movement, practicing Tai Chi improves body core muscle most significantly. It mainly attributes to the special way of exerting power and force of Tai Chi.2) Soft and slow movement can effectively improve the body balance ability. The main reason is related to the abundance of balance actions, as well as to the ability of psychological regulation.3) In slow motion, the effect of the soft and slow movement enhancing the muscle working function is significant. However, the effect is not evident in fast motion.
