This observational study investigated the use of continuous glucose monitoring (CGM) in a team professional cyclists without diabetes during two consecutive annual training camps. The goal was twofold: to present aggregated CGM metrics such as day/overnight average (DAYAVG/OVNAVG) for this group and association between exercise energy expenditure (megajoules per day), carbohydrate intake (grams), minimum overnight values (millimoles liter). Linear mixed models were employed analysis. Data available 26 (22 participated both camps). levels reported (DAYAVG = 6.37 ± 0.54 mmol/L OVNAVG 5.30 0.52 mmol/L), are not typically seen healthy individuals engaged intensive routines. Results showed that significantly fluctuated throughout camp, but statistically significant (p .0839) or .059) could be detected. research contributes literature on athletes underscores need further studies fully understand benefits limitations guide sports performance.
