“…The limitations of the present study were that evaluations were conducted only once during the race, the lack of a detailed evaluation of pre-race nutrition and training status, and not conducting a physiological test (i.e., maximal oxygen uptake and running economy test). The results of previous studies examining the relationship between BG pattern and endurance performance are inconsistent, and this is probably related to various factors including quantity, content, timing of pre-race meals, supplementation during the race [22][23][24], fitness levels [20], and race and/or ethnicity [25]. Thus, it will likely provide more valuable information to assess additional parameters in more detail and conduct measurements across multiple races with the same subjects.…”

Background: The effects of the use of continuous glucose monitoring (CGM) in elite endurance athletes are unclear. This case study reported the blood glucose (BG) levels of a female national-level marathon runner during a real-world marathon race. Methods: Heart rate and BG levels were monitored throughout the race. Results: The runner completed the race in 2:46 h:min, which was an improvement from her previous personal record by just under one min. Her BG levels were stable from approximately 5–40 km of the race at a mean concentration of 7.13 mmol/L, with a standard deviation of 0.20 mmol/L and a coefficient of variation of 2.8%. Increases in BG levels and heart rate were observed 6 min after the race and during the 40–42.195 km section, respectively. Conclusions: The runner broke her own record and exhibited stable BG levels throughout the race, with the highest BG value detected immediately after the race. Considering that quantity, content, and timing of pre-race meals and supplementation during the race can affect BG levels, future studies should assess additional detailed parameters in more detail and monitor multiple races with the same elite endurance athletes to acquire more definitive evidence on CGM usefulness among elite endurance athletes.

“…When blood glucose levels drop, the body breaks down glucose into energy (Sudrajat et al, 2023), which can lead to increased levels of lactate acid in the blood. When working for long periods of time, workers may experience decreased energy and occupational fatigue (Koma & Terasawa, 2020).…”

Occupational fatigue remains a prevalent concern in occupational health. This study investigated the association between noise intensity, blood glucose levels, body mass index (BMI), and lactate levels as an indicator of occupational fatigue among textile industry workers in Surakarta, Indonesia. An analytical observational study with a cross-sectional design was conducted, with 82 participants recruited from a local textile industry. Multivariate analysis using multiple binary logistic regression revealed that noise intensity, blood glucose levels, and BMI were significant risk factors for occupational fatigue, as indicated by elevated lactate levels. These findings highlight the importance of noise reduction measures, a healthy lifestyle, and regular monitoring of blood glucose levels and BMI to mitigate occupational fatigue among textile industry workers

“…Administration of Taurine was found to have a favorable influence on exercise-induced fatigue and exercise performance and recovery [ 12 , 13 ]. Similarly, glucose is the basic form of carbohydrate that can enhance the production of the molecular unit of currency (adenosine triphosphate, ATP), reduced exercise-induced fatigue, and improve exercise performance [ 14 , 15 ]. In fact, both Taurine and glucose have commonly been added to EDs [ 1 ] due to their beneficial effects on exercise performance and recovery.…”

This study examined the effects of a non-caffeinated energy drink (ED) that contained calamansi juice, glucose, and taurine on 3-km running performance and recovery. Eleven NCAA Division I middle-distance runners (20.8 ± 1.5 years old) were randomly assigned to consume either the ED or a placebo drink 60 min before 3-km running on a 400-m official track. Performance time and speed were recorded every 500-m interval. Recovery blood lactate concentration (BLC), systolic (SBP), diastolic blood pressure (DBP), and heart rate (HR) were measured at baseline, 60-min after ingesting the drinks, and post-running measurements were performed at 1-min, 5-min, and 10-min. Repeated analysis of variance and paired t-test were applied to examine the effects of time, trials, and their interaction on performance and recovery. Statistical significance was set a priori at p < 0.05. No significant difference was observed in performance time and speed between trials (p < 0.05). No interaction effect was found on performance time, speed, recovery BLC, DBP, and HR (p < 0.05). However, an interaction effect for trial by time was observed on SBP (p = 0.01). Recovery SBP continues to decrease from 5-min to 10-min in the ED trial (∆ = −13.9·mmHg) and slightly increased in the placebo trial (∆ = 1.1·mmHg). This study suggests that acute consumption of a calamansi-containing ED can positively impact the SBP recovery but not running performance. Further studies are needed to examine the acute and chronic effects of this ED on exercise performance and recovery among different populations.
