2023年4月27日首次应用研究来评估设备发现它可能发现变化与饮食有关。发表在《国际运动营养协会,由英吉利Ruskin大学的研究人员(阿鲁),这项研究评估腔,制造商声称是第一个设备允许人们监控代谢燃料使用在家里。第一应用研究——研究调查的实际使用这个手持呼吸设备,分为两个部分。第一部分是确认其有效性在实验室控制条件下,与腔道格拉斯袋测试相比,黄金标准衡量呼吸系统分析。这涉及到12名健康志愿者在禁食条件下食用高碳水化合物的一餐。呼吸措施静止,然后30和60分钟后餐使用腔装置和道格拉斯袋空气分析测试。腔捕获二氧化碳(CO2)的百分比作为用户呼吸,它演示了一个显著增加% 30分钟内二氧化碳高碳水化合物的一餐。过期的二氧化碳的增加与更大程度的碳水化合物被用作能量,通常量化的r在实验室条件下(呼吸道交换比率)值。%的二氧化碳的增加测量的内腔与r的增加,结果表明,碳水化合物的设备可以检测急性变化使用。这项研究的第二部分研究设备能否检测代谢变化在正常饮食,然后在回答在一周期间的高或低碳水化合物饮食。 The participants, 27 healthy active adults, were requested to take measures at home using the Lumen device at set points during each day of their diet under normal living conditions, to represent how the device may typically be used. The results showed that the Lumen device can detect changes in the participants’ %CO2 over the week in response to acute dietary modifications but was not sensitive on a day-to-day basis, indicating it might be more suited to longer term tracking. As the device does not measure oxygen consumption, it can only provide indirect measures of metabolic fluctuations, but the researchers believe it could support dietary changes, particularly relating to carbohydrate intake. Lead author Dr Justin Roberts , Associate Professor in Nutritional Physiology for Health & Exercise at Anglia Ruskin University (ARU), said: “Ours is the first study to investigate the practical use of this breath device. What makes this technology interesting is that up to now, the only way to assess metabolic function has been under laboratory conditions using advanced and expensive respiratory analysers. “When people leave the lab there are limited means to accurately assess metabolic changes at home, such as fuel use and whether the person is likely burning more fat or carbohydrates, either in response to a diet or exercise. “Therefore, the findings from our study demonstrate that a home-use portable device like Lumen could be a useful way of tracking weekly changes in dietary interventions when dietary carbohydrate is the main variable being changed. It should be noted that our study only tracked for a short period, therefore longer-term studies are needed to assess whether the device can detect metabolic adaptations over time. “However, the Lumen device could be a useful tool to support research and dietary interventions. It may offer a practical solution to tracking dietary changes, particularly in relation to regular exercise, but users should be mindful of the complexity of metabolic adaptations and interpretation of data on a day-to-day basis.” The researchers at Anglia Ruskin University (ARU) did not receive funding for the study, other than the loan of equipment, and had full control over the research and publication.
