Nine cyclists (age: 26 ± 5 years, height: 168 ± 5 cm and mass 58.5 ± 4.5 kg) were observed using continuous glucose monitoring devices throughout a training camp. Interstitial glucose [iG] data were captured via the Abbott libre sense biosensor (Abbott Laboratories) and paired with the Supersapiens software (TT1 Products Inc.). [iG] data were split into time ranges, that is, overall (24-hourly), day-time (06:00-23:59), night-time (00:00-05:59) and exercise. [iG] data were stratified into percentage of time, below range ([TBR] < 70 mg/dl), in range ([TIR] 70-140 mg/dl) and above range ([TAR] ≥ 141 mg/dl). Differences in diurnal and nocturnal data were analysed via repeated measures analysis of variance and paired t-tests where appropriate. p-value of ≤0.05 was accepted as significant. Riders spent an average of 3 ± 1% TAR, 93 ± 2% TIR and 8 ± 3% TBR. Mean 24 h [iG] was 93 ± 2 mg/dl with a coefficient of variation (CV) of 18 ± 1%. Mean (day: 95 ± 3 vs. night: 86 ± 3 mg/dl and p < 0.001) and CV (day: 18 ± 1 vs. night: 9 ± 1% and p < 0.001) in [iG] were higher during the day-time hours. TAR was greater during the day (day: 3 ± 1 vs. night: 0 ± 0% and p < 0.001) but TBR and TIR were similar. Glucose levels below the clinical range may have implications for those without diabetes and warrants further investigation.
九名自行车运动员（年龄：26±5 岁，身高：168±5cm，体重：58.5±4.5kg）在整个训练营期间都使用连续血糖监测设备进行观察。间质葡萄糖 [iG] 数据通过 Abbott libre sense 生物传感器（Abbott Laboratories）捕获，并与 Supersapiens 软件（TT1 Products Inc.）配对。[iG] 数据分为时间范围，即总体（24 小时）、白天（06:00-23:59）、夜间（00:00-05:59）和运动。[iG] 数据按百分比时间分层，即低于范围（[TBR] <70mg/dl）、在范围内（[TIR] 70-140mg/dl）和高于范围（[TAR] ≥141mg/dl）。通过适当的重复测量方差分析和配对 t 检验分析昼夜数据的差异。p 值≤0.05 被认为具有统计学意义。骑手的 TAR 平均占 3±1%，TIR 占 93±2%，TBR 占 8±3%。24 小时平均[iG]为 93±2mg/dl，变异系数（CV）为 18±1%。平均（白天：95±3 与夜间：86±3mg/dl，p<0.001）和 CV（白天：18±1 与夜间：9±1%，p<0.001）在白天时间更高。TAR 在白天更高（白天：3±1 与夜间：0±0%，p<0.001），但 TBR 和 TIR 相似。低于临床范围的血糖水平可能对没有糖尿病的人有影响，需要进一步研究。
