摘　　要：Background： Prolonged sitting is a risk factor for low-back pain. The primary purpose of this study is to determine if prolonged active sitting will result in increased trunk motion. Methods： Fifteen healthy female participants volunteered to sit for 30 vain on each of three surfaces including an air-cushion, a stability ball, and a hard surface. Trunk motion was monitored using a Vicon motion capture system, and foot center of pressure was collected with two AMTI force plates. Results： Our findings indicated that the average speed of the trunk center of mass significantly increased with seating surface compliance. There were significant differences in fight and left foot centers of pressure in the antero-posterior direction between the ball and air-cushion conditions and the ball and chair conditions. Conclusion： Active sitting results in increased trunk motion and could have a positive effect on low-back health.背景:久坐极易导致腰痛。本研究旨在确定积极坐姿是否会增加躯体运动。方法:15名健康女性志愿者分别在气垫、稳定球和硬面这三种不同材质的坐具上坐30分钟。用Vicon运动捕捉系统检测躯干运动,用两块AMTI力板收集两脚的压力中心。结果:躯干中心质量的平均速度随坐具表面柔软度增加而明显增加。受试者坐于稳定球上时两脚前后方向上的压力中心明显不同于坐在气垫和硬面椅上。结论:积极坐姿能促进躯体运动并有益于腰部健康。
