目的 随着人民生活水平不断提高,越来越多人选择在健身房内使用椭圆交叉训练机进行日常锻炼。本文对锻炼过程中引起的人体的生物力学与动力学特性进行了分析与研究。方法 通过Solidworks软件建立一种椭圆交叉训练机模型,在Anybody软件中建立人体骨肌模型,然后将人体骨肌模型与椭圆交叉训练机模型进行耦合仿真。 结果 分析得出,人体腰腹部不同肌肉受力变化和肌肉激活程度变化、脊椎的不同部位受力变化、下肢主要肌群肌肉的肌肉激活程度变化和主要关节受力变化情况。结论 为人体使用椭圆交叉训练机进行科学锻炼作理论指导和对椭圆交叉训练机的人性化设计提供了参考。
Objective With the continuous improvement of people"s living standards, more and more people choose to use fitness equipment for daily exercise in the gym. This article analyzes and studies the biomechanical and dynamic characteristics of the human body caused by the exercise crowd when using the elliptical cross trainer. Methods An elliptical cross trainer model was established by Solidworks software, a human skeletal muscle model was established in Anybody software, and then the human skeletal muscle model and the elliptical cross trainer model were coupled and simulated. Results The analysis shows that when the human body is exercising on the elliptical machine, the stress on the spine starts from the lumbar spine T12 to the thoracic spine T5 and gradually increases and the force is greatest at T5. The three muscles with the highest muscle activation at the trunk are: External obliques, internal obliques, and transverse abdominal muscles. Conclusion It provides a reference for the human body to use the elliptical cross trainer for scientific training as a theoretical guide and the humanized design of the elliptical cross trainer.
