Transmission of vertical whole body vibration to the human body.
According to experimental studies, low-amplitude high-frequency vibration is anabolic to bone tissue, whereas in clinical trials, the bone effects have varied. Given the potential of whole body vibration in bone training, this study aimed at exploring the transmission of vertical sinusoidal vibration to the human body over a wide range of applicable amplitudes (from 0.05 to 3 mm) and frequencie...
متن کاملResponse of the seated human body to whole-body vertical vibration: biodynamic responses to mechanical shocks.
The biodynamic response of the seated human body has been investigated with 20 males exposed to upward and downward shocks at 13 fundamental frequencies (1-16 Hz) and 18 magnitudes (up to ±8.3 ms-2). For 1- and 2- degree-of-freedom models, the stiffness and damping coefficients were obtained by fitting seat acceleration waveforms predicted from the measured force to the measured seat accelerati...
متن کاملEffect of body supination angle on subjective response to whole-body vibration.
Three experiments were conducted to evaluate the subjective symptomatology associated with various combinations of supination angle and vibration spectral composition. Sinusoidal, sum-of-sine, and random vibration were used in the first, second and third experiments, respectively. All exposure periods were 40 s and the supination angle was varied from 13-65 degrees. Subjective response was eval...
متن کاملResponse of the seated human body to whole-body vertical vibration: discomfort caused by mechanical shocks.
The frequency dependence of discomfort caused by vertical mechanical shocks has been investigated with 20 seated males exposed to upward and downward shocks at 13 fundamental frequencies (1-16 Hz) and 18 magnitudes (±0.12 to ±8.3 ms-2). The rate of growth of discomfort with increasing shock magnitude depended on the fundamental frequency of the shocks, so the frequency dependence of equivalent ...
متن کاملChanges of Nerve - Muscle Performance of Elderly Men in Response to Whole Body Vibration
Background and Aims: Whole body vibration exercise by affecting the neuromuscular system and mechanical mechanisms increase muscles strength. This study investigated the effect of whole body vibration training on neuromuscular function of elderly men. Methods: Based on a randomized controlled trial design, 72 retired elderly men with a mean age of 73.00 ± 2.67 years participated in thisstudy. A...
