简要总结
Aging of the neuromuscular system may lead to an increased risk of falls in older adults. There are external and internal factors for falls, and lower limb muscle strength and balance are important internal factors for falls in the elderly. And can be improved through exercise. Therefore, an important interventional goal in interventional exercises to prevent falls in the elderly is to promote balance and increase lower extremity muscle strength.
Flexi-bar is a device that provides vibration stimulation. Studies have shown that a 5Hz frequency can be generated when shaken and transmitted to the whole body. Flexi bar is now widely used in fitness centers or rehabilitation therapy to improve muscle strength and balance. Vibration activates the tonic reflex, enhances the excitability of alpha and gamma motor neurons and enhances motor unit synchronization, and this active vibration training helps increase muscle coordination as it induces the tonic reflex and stimulates the proprioception of the joint Feelings, these physiological changes can lead to more effective proprioceptive feedback that improves balance. And because the vibration causes the agonist and antagonist muscles to contract alternately to regulate the instability during the movement. In recreational athletes, the use of a flexi bar in a single-legged position can effectively induce lower extremity muscle activation.
A 12-week combination of balance and strength training in older adults has been shown to be effective in reducing the risk of falls in older adults in previous studies.
Since the effect of adding Flexi bar on the basis of balance and strength training is unknown, the purpose of this study was to investigate the experimental group and the control group with the same exercise posture and training time, Flexi bar + BST Is it better for the balance and muscle strength of the elderly than simple BST?
