Abstract

Objective: This study aimed to investigate the effects of combined elastic band resistance training (EBRT) and whole-body vibration training (WBVT) on lower limb isokinetic muscle strength, balance and physical performance in older women with history of falls.

Methods: A total of 102 older women with a history of falls was randomly assigned to the elastic band group (n = 28), vibration group (n = 28), elastic band plus vibration group (n = 28) and control group (n = 28) for a 12-week program. All groups performed identical exercises (half squats, static squats, left/right lunges) thrice weekly. The control group trained on a flat ground without elastic bands or vibration; the elastic band group used elastic bands on the flat ground, while the vibration and combined groups exercised on a vibration platform. Training parameters included 3 sets × 10 repetitions with 20-s rest intervals.

Results: Post-intervention, knee flexion peak torque increased by 9.7% (p < 0.05). Total length (TL), elliptical area (EA), total offset index (TAI), timed up and go test (TUG) and five times sit-to-stand test (FTSST) decreased by 16.2%, 14.2%, 21.9%, 16.9% and 14.0%, respectively; and modified fall efficacy scale (MFES) increased by 17.6% (p < 0.01) in the elastic band group. Knee extension peak torque increased by 16.3% (p < 0.05). TL, EA, TAI, TUG and FTSST decreased by 14.8%, 12.2%, 18.9%, 12.3% and 11.5%, respectively; and MFES increased by 16.2% in the vibration group (p < 0.01). Hip and knee flexion and knee and ankle extension peak torque increased by 19.5%, 18.8%, 30.2% and 30.1% (p < 0.01), respectively, in the elastic band plus vibration group. TAI, TL, EA, TUG and FTSST decreased by 28.5%, 24.6%, 38.3%, 22.4% and 29.0%, respectively, and MFES increased by 42.1% in the elastic band plus vibration group (p < 0.01). The elastic band plus vibration group demonstrated greater improvements in knee and ankle strength compared to single interventions, while the elastic band and vibration groups showed smaller changes (p < 0.05). Additionally TL, EA, TAI, TUG, and FTSST all decreased, while MFES increased (p < 0.05).

Conclusion: The combined EBRT and WBVT can enhance knee and ankle isokinetic muscle strength, improve balance ability and physical performance and reduce fear of falls by a greater degree than single interventions. EBRT and WBVT had limited effects on improving lower limb isokinetic muscle strength but enhanced balance ability, physical performance, and reduced fear of falls in older women with a history of falls.

弹力带和振动训练对有跌倒史的老年妇女肌肉力量、平衡和活动能力的协同作用：一项随机对照试验

目的：本研究旨在探讨弹性带阻力训练（EBRT）和全身振动训练（WBVT）联合训练对有跌倒史的老年女性下肢等速肌力、平衡和体能表现的影响。方法：将102例有跌倒史的老年妇女随机分为弹力带组（n = 28）、振动组（n = 28）、弹力带加振动组（n = 28）和对照组（n = 28），为期12周。所有组每周进行三次相同的锻炼（半深蹲，静态深蹲，左/右弓步）。对照组在没有橡皮筋和振动的平坦地面上训练；弹性带组在平坦的地面上使用弹性带，而振动组和组合组在振动平台上进行锻炼。训练参数为3组× 10次重复，休息时间为20秒。结果：干预后膝关节屈曲峰值扭矩增加9.7% （p < 0.05）。总长度（TL）、椭圆面积（EA）、总偏置指数（TAI）、定时上走试验（TUG）和5次坐立试验（FTSST）分别下降了16.2%、14.2%、21.9%、16.9%和14.0%；改良跌倒效能量表（MFES）评分提高17.6% （p < 0.01）。膝关节伸展峰值扭矩增加16.3% （p < 0.05）。TL、EA、TAI、TUG和FTSST分别下降14.8%、12.2%、18.9%、12.3%和11.5%；振动组MFES升高16.2% （p < 0.01）。弹性带加振动组髋膝屈曲和膝踝伸峰扭矩分别提高19.5%、18.8%、30.2%和30.1% （p < 0.01）。弹性带加振动组TAI、TL、EA、TUG和FTSST分别降低28.5%、24.6%、38.3%、22.4%和29.0%，MFES升高42.1% （p < 0.01）。与单一干预相比，弹力带加振动组在膝关节和踝关节力量方面的改善更大，而弹力带加振动组的变化较小（p < 0.05）。TL、EA、TAI、TUG、FTSST均降低，MFES升高（p < 0.05）。结论：与单一干预相比，EBRT联合WBVT能更大程度地增强膝关节和踝关节等速肌力，提高平衡能力和体能，减少跌倒恐惧。EBRT和WBVT对改善下肢等速肌肉力量的作用有限，但对有跌倒史的老年妇女的平衡能力、身体表现和减少对跌倒的恐惧有增强作用。两种训练方式都显示出相似的效果。

期刊介绍： The translation of new discoveries in medicine to clinical routine has never been easy. During the second half of the last century, thanks to the progress in chemistry, biochemistry and pharmacology, we have seen the development and the application of a large number of drugs and devices aimed at the treatment of symptoms, blocking unwanted pathways and, in the case of infectious diseases, fighting the micro-organisms responsible. However, we are facing, today, a dramatic change in the therapeutic approach to pathologies and diseases. Indeed, the challenge of the present and the next decade is to fully restore the physiological status of the diseased organism and to completely regenerate tissue and organs when they are so seriously affected that treatments cannot be limited to the repression of symptoms or to the repair of damage. This is being made possible thanks to the major developments made in basic cell and molecular biology, including stem cell science, growth factor delivery, gene isolation and transfection, the advances in bioengineering and nanotechnology, including development of new biomaterials, biofabrication technologies and use of bioreactors, and the big improvements in diagnostic tools and imaging of cells, tissues and organs. In today`s world, an enhancement of communication between multidisciplinary experts, together with the promotion of joint projects and close collaborations among scientists, engineers, industry people, regulatory agencies and physicians are absolute requirements for the success of any attempt to develop and clinically apply a new biological therapy or an innovative device involving the collective use of biomaterials, cells and/or bioactive molecules. “Frontiers in Bioengineering and Biotechnology” aspires to be a forum for all people involved in the process by bridging the gap too often existing between a discovery in the basic sciences and its clinical application.
