To provide a vibration testing installation capable of vibrating a subject to evaluate the effect of vibration he/she may receive while he/she is walking or running.

When the subject M start walking on the walking surface 6a the detection device 8 detects the contact/release of the feet LR, LL of the subject M to/from the walking surface 6a and out puts the ON/OFF signal to the operation device 9. The operation device 9 calculates the walking interval T based on the past ON/OFF signal former than present and also calculates estimate operation at the time in future after the laps of time from present for estimating the contact between the subject M and the walking surface 6a based on the walking interval T. The control device 10 controls the timing of vibration the excitation device 7 so as to vibrate the walking surface 6a at a time in future, and also controls the timing of photographing of photographic devices 11, 12 so as to take photographs by the devices from the time in future for an prescribed interval.
