Abstract

Abstract:

BACKGROUND: There is a lack of systematic study concerning the impact of backward movement on the physical posture control in elderly women.
OBJECTIVE: To explore the effect of regular backward exercise on the balance, muscle strength and neuromuscular response latency of the lower extremities in healthy elderly women, so as to provide a theoretical basis for backward exercise improving the ability of controlling the posture to prevent falling in older adults.
METHODS: Healthy elderly female volunteers recruited in Qing’an community in Wuhou District, Chengdu were recruited between February and March 2017, and randomly divided into experimental group (n=28) and control group (n=26), which were matched in age, height and body mass. The experimental group was subjected to backward exercise (70 minutes/time), thrice weekly for 24 weeks.
RESULTS AND CONCLUSION: After 24 weeks, in the static balance test, there was a decrease in the Sway index in standing on a fixed platform/sponge mat with eyes closed. In the dynamic balance test, the score of backward was increased, the absolute/explosive force of knee joint flexion, and the force and explosive force of ankle joint extension were increased; the anterior response latency of tibialis anterior and gastrocnemius was reduced. To conclude, 24-week backward exercise can improve the balance ability of the elderly female subjects, enhance the muscle strength of lower extremities, and shorten the neuromuscular response latency of lower extremities, thus effectively promoting physical posture control.|
