We studied the effect of vibratory stimulation of different leg muscles [bilateral quadriceps (Q), hamstring (HS) muscles, triceps surae (TS), and tibialis anterior (TA)] in seven normal subjects during 1) quiet standing, 2) stepping in place movements, and 3) walking on the treadmill. The experiments were performed in a dimly illuminated room, and the subjects were given the instruction not to...

To investigate the vestibular and somatosensory interaction in human postural control, a galvanic vestibular stimulation of cosine bell shape resulting in a small forward or backward body lean was paired with three vibrations of both soleus muscles. The induced body lean was registered by the position of the center of foot pressure (CoP). During a quiet stance with eyes closed the vibration of ...

The aim of this study was to investigate and to compare the effect of 24 weeks "whole body vibration" training and fitness training on body composition and on muscle strength. Forty-eight untrained females (21.3 +/- 2.0 yr) participated in the study. The whole body vibration group (N = 18) performed unloaded static and dynamic exercises on a vibration platform (35 - 40 Hz, 2.5 - 5.0 mm; Power P...

In this study, the effects of vibration training on physical fitness factors in elderly females investigated. 40 subjects with age 61/09±6/24 yrs, weight 65/84±11/98 kg, height 156/99±5/06 cm and body mass index 26/64±4/23 kg/m2 voluntary participated in this study and were divided in vibration (n=16), non-vibration (n=14) and control (n=10) groups. The vibration group performed exercises o...

In the various working field, vibration may cause injurious to human body. Especially, in case of the vibration which is constantly and repeatedly transferred to the human. That gives serious physical problem, so called, Reynaud phenomenon. In this paper, we propose a vibration transmissibility reduction module with flexure mechanism for personal tools. At first, we select a target personal too...

Many studies have demonstrated the benefits of wearable vibration devices for walking navigation (Tsukada and Yasumura, 2004). Despite the potential benefits, suitable body parts for wearable vibration devices have not been defined or evaluated until now. We conducted three experiments to identify suitable body parts in terms of perceivability, wearability and user body location preferences for...

Background and Objectives: city bus drivers, during driving, are always exposed to the whole body vibration. This can lead to central- neural, musculoskeletal, and blood circulation disorders and develop occupational diseases due to vibration. The objective of this descriptive- analytic study is to investigate Tehran bus drivers;apos exposure to the whole body vibration. Materials and Metho...

PURPOSE The purpose of this study was to determine the effectiveness of whole-body passive vibration exercise and its differences from aerobic exercise on body composition, bone mineral density (BMD) and bone mineral content (BMC). METHODS Obese middle-aged women (n=33 out of 45) with 34±3% body fat completed the training protocol. They were randomly assigned into diet (n=9; control group), d...
