Filter by: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?
120 participants will be randomized into one of two groups that will perform resistance training at a gym three time per week for three months. One group will follow common resistance training guidelines, whereas the other will exercise according to their preferences and perception of effort. The groups will be compared on the following primary outcomes after six and 12 weeks: body composition, physiological and performance tests. The groups will be compared on the following secondary outcomes every two weeks: enjoyment and satisfaction levels. Adherence rates will be measured throughout the intervention.
A group of 50 age-schooled adolescents was randomized into one intervention and another control group of 25 subjects each. After estimating one maximum repetition for all the participants in a previous session, the intervention group performed a resistance training based on a resistance exercise of 3 sets of 3 to 5 repetitions (90% of an estimated 1 RM) whereas the control group performed both stretching and balance exercises. Measures of executive functions ( i.e. a cognitive function associated with academic performance) were taken for all the participants before and after the training. Both independent and paired t-test will serve to check differences between and within groups respectively.
