生物陶瓷面料被认为可以改善血液循环、体温调节和肌肉放松，从而改善肌肉活动。在这里，我们测试了生物陶瓷面料是否对姿势控制有影响，并有助于改善姿势稳定性。在实验1中，我们测试了生物陶瓷面料在保持标准站姿时是否有助于减少身体摇摆。在实验2中，我们测量了生物陶瓷面料在保持更不稳定的姿势，即倒立握法时对身体摇摆的影响。在这两个实验中，使用带有四个应变片的测力台来测量姿势振荡，这些应变片记录了压力中心(Cop)在水平面上的位移。在一半的试验中，参与者穿着含有生物陶瓷层的全身第二套皮肤套装。在另一半的试验中，他们穿了一套“安慰剂”的第二套皮肤套装，其裁剪、外观和弹性与生物陶瓷套装相同，但不包含生物陶瓷层。在这两个实验中，当参与者穿着生物陶瓷套装时，COP的移位表面比穿着安慰剂套装时要小得多。结果表明，生物陶瓷面料确实具有姿势控制和改善姿势稳定性的效果。(C)2015爱思唯尔B.V.保留所有权利。
Bioceramic fabrics have been claimed to improve blood circulation, thermoregulation and muscle relaxation, thereby also improving muscular activity. Here we tested whether bioceramic fabrics have an effect on postural control and contribute to improve postural stability. In Experiment 1, we tested whether bioceramic fabrics contribute to reduce body-sway when maintaining standard standing posture. In Experiment 2, we measured the effect of bioceramic fabrics on body-sway when maintaining a more instable posture, namely a handstand hold. For both experiments, postural oscillations were measured using a force platform with four strain gauges that recorded the displacements of the center of pressure (Cop) in the horizontal plane. In half of the trials, the participants wore a full-body second skin suit containing a bioceramic layer. In the other half of the trials, they wore a 'placebo' second skin suit that had the same cut, appearance and elasticity as the bioceramic suit but did not contain the bioceramic layer. In both experiments, the surface of displacement of the CoP was significantly smaller when participants were wearing the bioceramic suit than when they were wearing the placebo suit. The results suggest that bioceramic fabrics do have an effect on postural control and improve postural stability. (C) 2015 Elsevier B.V. All rights reserved.
