Abstract

The main focus of this work is to investigate the effect of weight on the stability of human squat exercise. The squat exercise is a common daily activity. Experiments are conducted using one human subject. A VICON motion analysis system integrated with Force Plates is utilized for these experiments. An experimental protocol is developed and followed. This work analyzes the time series of the normal component of the ground reaction forces and each coordinate of the center of pressure. These time series are used to estimate the Lyapunov Exponents using Rosenstein method. MATLAB software package is used for this investigation. The results of this work are compared with results from literature. Present work gives more information relating the safety of the squat exercise when adding additional weight. One can see that the effect of additional weight on stability depends on its value. In the cases of small and moderate additional weight the stability is the same or increases, while for the largest additional weight the investigated stability decreases.

额外重量对人体深蹲运动稳定性的影响:地面反作用力和压力中心

本研究的重点是研究重量对人体深蹲运动稳定性的影响。深蹲运动是一项常见的日常活动。实验是在一个人身上进行的。实验采用了一个集成了力板的VICON运动分析系统。制定并遵循实验方案。本文分析了地面反力法向分量和压力中心各坐标的时间序列。利用这些时间序列利用Rosenstein方法估计Lyapunov指数。本研究采用MATLAB软件包。本工作的结果与文献的结果进行了比较。目前的工作提供了更多关于增加额外重量时深蹲运动安全性的信息。可以看出，附加重量对稳定性的影响取决于它的值。在较小和中等附加重量的情况下，稳定性相同或增加，而在最大附加重量的情况下，稳定性下降。

期刊介绍： This international journal publishes both theoretical and application-oriented papers on various aspects of mechatronic systems, modelling, design, conventional and intelligent control, and intelligent systems. Application areas of mechatronics may include robotics, transportation, energy systems, manufacturing, sensors, actuators, and automation. Techniques of artificial intelligence may include soft computing (fuzzy logic, neural networks, genetic algorithms/evolutionary computing, probabilistic methods, etc.). Techniques may cover frequency and time domains, linear and nonlinear systems, and deterministic and stochastic processes. Hybrid techniques of mechatronics that combine conventional and intelligent methods are also included. First published in 1972, this journal originated with an emphasis on conventional control systems and computer-based applications. Subsequently, with rapid advances in the field and in view of the widespread interest and application of soft computing in control systems, this latter aspect was integrated into the journal. Now the area of mechatronics is included as the main focus. A unique feature of the journal is its pioneering role in bridging the gap between conventional systems and intelligent systems, with an equal emphasis on theory and practical applications, including system modelling, design and instrumentation. It appears four times per year.
