Abstract

The purpose of the present study was to examine the validity and reliability of the handheld Nova Max Plus blood glucose monitor during an oral glucose tolerance test and 60-minute bout of exercise. Thirty subjects (mean age±SD=22.3±1.9 years; body mass=77.6±14.2 kg) volunteered for an oral glucose tolerance test or 60-minute treadmill test. Blood glucose concentrations were measured from the fingertip at six time points during both tests. The reference method of blood glucose analysis was the Yellow Springs Instruments (YSI) 2300. Our results indicated that the blood glucose values provided by the Nova Max Plus were significantly (p<.05) greater than the YSI 2300 at all-time points of the oral glucose tolerance test and treadmill test. In addition, the Nova Max Plus exhibited an overall mean absolute relative deviation (±SD) of 9.0 (±7.0) and did not meet the 95% accuracy requirements of ISO 15197:2013. The Bland-Altman plot for constant error (YSI 2300 – Nova Max Plus) versus the reference method (YSI 2300) indicated an average negative bias (-8.2 mg·dL-1) that increased (r=-0.23) at higher blood glucose values. Intra-device reliability analyses for the Nova Max Plus demonstrated the ICC was R=0.99 and CV=3.0%, with no mean differences between the test and retest values. These findings suggested that the Nova Max Plus provided highly reliable, yet inaccurate blood glucose values compared to the YSI 2300 during the dynamic conditions associated with an oral glucose tolerance test and exercise.

手持式血糖监测仪在运动和口服葡萄糖耐量测试中的有效性和可靠性

本研究的目的是检验手持式Nova Max Plus血糖监测仪在口服葡萄糖耐量试验和60分钟运动期间的有效性和可靠性。30例(平均年龄±SD=22.3±1.9岁;体重=77.6±14.2 kg)的志愿者接受了口服葡萄糖耐量试验或60分钟跑步机试验。在两项试验中，从指尖在六个时间点测量血糖浓度。血糖分析参考方法为黄泉仪器(YSI) 2300。我们的研究结果表明，在口服葡萄糖耐量试验和跑步机试验的所有时间点，Nova Max Plus提供的血糖值显著(p< 0.05)高于YSI 2300。此外，Nova Max Plus的总体平均绝对相对偏差(±SD)为9.0(±7.0)，不符合ISO 15197:2013 95%的精度要求。恒定误差(YSI2300 - Nova Max Plus)与参考方法(YSI2300)的Bland-Altman图显示，在血糖值较高时，平均负偏差(-8.2 mg·dL-1)增加(r=-0.23)。NovaMax Plus的设备内可靠性分析表明，ICC的R=0.99, CV=3.0%，测试值和重新测试值之间没有平均差异。这些发现表明，在与口服葡萄糖耐量试验和运动相关的动态条件下，与YSI 2300相比，Nova Max Plus提供了高度可靠但不准确的血糖值。

期刊介绍： Kinesiology – International Journal of Fundamental and Applied Kinesiology (print ISSN 1331- 1441, online ISSN 1848-638X) publishes twice a year scientific papers and other written material from kinesiology (a scientific discipline which investigates art and science of human movement; in the meaning and scope close to the idiom “sport sciences”) and other adjacent human sciences focused on sport and exercise, primarily from anthropology (biological and cultural alike), medicine, sociology, psychology, natural sciences and mathematics applied to sport in its broadest sense, history, and others. Contributions of high scientific interest, including also results of theoretical analyses and their practical application in physical education, sport, physical recreation and kinesitherapy, are accepted for publication. The following sections define the scope of the journal: Sport and sports activities, Physical education, Recreation/leisure, Kinesiological anthropology, Training methods, Biology of sport and exercise, Sports medicine and physiology of sport, Biomechanics, History of sport and Book reviews with news.
