背景:使用个人偏爱的有色眼镜已经普及,期望它可以改善平衡控制和运动表现,然而,以前的研究结果仍然没有定论.
目的:在本试点研究中,我们的目的是确定参与者佩戴五种不同颜色眼镜时的主观偏好和站立平衡表现之间的关联。
方法:13名参与者在一对同步力量平台上用一条腿或两条腿站立30秒,在5-5项随机姿态试验之间休息60秒,虽然穿着红色,蓝色,黄色,绿色,或透明的彩色眼镜。除了7个与CoP相关的变量外,我们分析了三条下肢肌肉的EMG数据的五个特征。
结果:没有发现有色眼镜的显著影响。一些CoP(速度:χ²(4,13)=10.086;p=0.039;Kendall\sW=0.194,均方根[RMS]:χ²(4,13)=12.278;p=0.015;Kendall\sW=0.236)和EMG相关(股二头肌的RMS:χ(4,13)s=13.006;p=0.011在所有姿势之间的优势然而,参与者未能连续确定站立稳定性的这些差异.
结论:总体而言,我们的结果可能表明镜片颜色偏好,不管颜色本身,可能会影响优势腿站立平衡最可能是由于心理因素,然而,只有主观的决定是没有潜力的,以确定的颜色的眼镜,将支持个人的站立平衡最。
BACKGROUND: The use of individually preferred colored glasses has gained popularity with the expectation that it may improve balance control and sports performance, however, the results of previous studies remain inconclusive.
OBJECTIVE: In the present pilot
study, we aimed to determine the association between participants\' subjective preference and standing balance performance when wearing five different colored glasses.
METHODS: Thirteen participants stood on one or two legs on a pair of synchronized force platforms for 30 seconds with 60 seconds rest between the five-five randomized stance trials, while wearing red, blue, yellow, green, or transparent colored glasses. In addition to 7 CoP-related variables, we analyzed five features of EMG data from three lower limb muscles on both legs.
RESULTS: No significant effect of colored glasses was found. Some CoP (velocity: χ²(4, 13) = 10.086; p = 0.039; Kendall\'s W = 0.194, root mean square [RMS]: χ²(4, 13) = 12.278; p = 0.015; Kendall\'s W = 0.236) and EMG-related (RMS of biceps femoris: χ²(4, 13) = 13.006; p = 0.011; Kendall\'s W = 0.250) variables showed differences between the colored glass conditions during dominant-leg stance, however, participants failed to consecutively determine these differences in standing stability.
CONCLUSIONS: Overall, our results may suggest that lens color preference, irrespective of the color itself, may influence dominant leg standing balance most probably due to psychological factors, however, only subjective determination have no potential to determine the color of the glasses that would support the individual\'s standing balance the most.
