TAI CHI IMPACTS ON NEUROMUSCULAR FUNCTIONS IN THE LOWER LIMBS OF THE ELDERLY

EFEITO DO TAI CHI SOBRE AS FUNÇÕES NEUROMUSCULARES NOS MEMBROS INFERIORES DOS IDOSOS

EFECTO DEL TAI CHI EN LAS FUNCIONES NEUROMUSCULARES DE LOS MIEMBROS INFERIORES DE LOS ANCIANOS

ABSTRACT

Introduction:

Exercise can retard the effects of aging and improve the physical function of the elderly. Tai Chi is a widespread exercise practice among the elderly in China. Although studies show the positive effects of Tai Chi practice, there is no consensus about compared studies.

Objective:

Evaluate the impact of regular Tai Chi exercise on neuromuscular stability in the lower limbs of elderly people, comparing the results of practitioners between sedentary and walking elderly groups.

Methods:

Twenty-two Tai Chi practitioners were selected, with a mean age of 59.3±3.5 years and a mean practice time of 18.4±13.2 years. This experiment mainly tests the balance ability compared to individuals practicing walking and other sedentary individuals.

Results:

The muscle strength of the knee flexors and extensors in the Tai Chi group was significantly greater than in the sedentary group (p=0.001 to 0.00160°/sec; P=0.002 to 60°/sec extensors; p=0.002 to 120°/sec; 120°/sec flexors, p=0.003). Similarly, there was a significant difference in muscle strength between the Tai Chi group and the walking group (the P values of the flexors and extensors at both speeds were less than 0.001).

Conclusion:

Tai Chi, as a regular exercise, can increase muscle strength of the general knee flexors and extensors and improve the neuromuscular stability of lower limbs in the elderly. Evidence Level II; Therapeutic Studies - Investigating the result.
