摘要

Body vibration not only may influence health, but also result in fatigue and injury. In addition, local vibration may result in local muscles, as well as local injury. In order to know the limitation that human can bear, we must have the basic understanding about the magnitude of vibrations due to different exercises, especially in the segments. Therefore, the purpose of this study is to compare the differences, using angular, angular velocity, and landing impulse and vibration responses between different heights and with shoes or bear foot for different segments. Moreover, this study attempts to establish the mathematical model of vibration responses for those segments.
The experimental design is to collect the vibration response from bare foot and footwear under three different heights by using Kodak high-speed camera (1000 Hz), Kistler forceplate (250 Hz), and Crossbow accelerometer (1024 Hz) to get the parameters of kinematics and dynamics. By analyzing the landing from different heights, the current research tries to figure out the landing vibration responses to different segments, including the lumbar, knee, hip, neck and the reacting force from ground. The data will be collected by movement film analysis, impulse analysis and power spectrum analysis. The results of this study could be applied to design the cushioning of shoes and floors.
After experiment, this study found the vibration of lumbar, knee, hip and neck with mean values and reacting force are linear for different height. The vibration of each segment increase as height increases.
