A new methodology for objective evaluation of discomfort in whole-body vibration (WBV) is introduced in this work. The proposed objective discomfort characterizes discomfort based on the relative motion between adjacent segments of the human body from neutral positions. It peaks when the joints reach their limits. The objective discomfort has been tested on five subjects in the fore-aft directi...

I. Abstract Nowadays people are strongly dependent on cars for doing their tasks, but they usually are not aware of hazards which are awaiting them. For instance, since people travel with cars, their human bodies undergo in fatigue, restlessness, and sometimes health problems. Human body reaction under external vibration depends on the amplitude, frequency, and acceleration of the applied exter...

BACKGROUND Benefits of community-based whole-body vibration (WBV) as a mode of exercise training for people with chronic obstructive pulmonary disease (COPD) have not been investigated. The low skill demand of WBV may enhance habitual sustainability to physical activity by people with COPD, provided efficacy of WBV can be established. The purpose of this trial was to compare a community-based W...

purpose aerobic exercise has been identified as the main treatment for type 2 diabetic patients. such an exercise, however, is usually repined by some of patients who suffer from lack of stamina. therefore, whole body vibration has recently been introduced as a passive intervention. the present study aimed at comparing how aerobic exercise and whole body vibration affect glycaemia control in ty...

Despite increasing use of whole body vibration during exercise an understanding of the exact role of vibration and the supporting physiological mechanisms is still limited. An important aspect of exercise analysis is the utilisation of oxygen, however, there have been limited studies considering tissue oxygenation parameters, particularly during dynamic whole body vibration (WBV) exercise. The ...

This randomized cross-over study was designed to investigate the effects of a 4-min vibration bout on muscle performance and body balance in young, healthy subjects. Sixteen volunteers (eight men, eight women, age 24-33 years) underwent both the 4-min vibration- and sham-interventions in a randomized order on different days. Six performance tests (stability platform, grip strength, isometric ex...

OBJECTIVE To clarify whether a short-term whole body vibration (WBV) training has an effect on lean mass (LM) in the elderly. METHOD 49 non-institutionalized elderly (20 men) participated in the study. Participants who met the inclusion criteria were randomly assigned to the WBV or control group. A total of 24 elderly trained squat positioned on a vibration platform 3 times per week for 11 we...

By new advancements in vehicle manufacturing vehicle quality evaluation and assurance has become a more critical issue. In present work, the vibration transfer path analysis and vibration path ranking of a car interior has been performed. The method is similar to classical multilevel TPA methods but has distinct differences. The method is named VIVS which stands for Vehicle Interior Vibratio...

To investigate the relationships between whole-body vibration and changes in wakefulness, We measured the change of a subjective wakefulness level and electroencephalogram (EEG). Subjects are ten healthy male university students. The subjects were exposed to whole-body vibration with frequency (10 Hz) and acceleration level (0.6 ms(-2) r.m.s.) for 12 min in the seated position. Subjective wakef...
