Continuous Glucose Monitoring in Athletes
Continuous Glucose Monitoring (CGM) is a technology that tracks the body's glucose levels in real time, providing valuable insights for athletes. It offers many benefits compared to traditional blood glucose testing. It involves a small sensor placed under the skin that measures interstitial glucose levels continuously, transmitting data to a device or smartphone. Its usefulness as a training tool and for performance enhancement of athletes is still being debated, and research is ongoing.
Continuous Glucose Monitoring is useful for endurance athletestarget population: Useful for athletes in endurance sports and team sports, particularly diabetic athletes.
test purpose: CGM helps athletes optimize their performance by identifying glucose fluctuations, thereby preventing energy crashes and enables them to fine-tune their nutrition strategies. Endurance athletes, in particular, benefit from maintaining stable glucose levels to sustain a stable energy output. It also aids in recovery by ensuring adequate fuels are ingested post-exercise.
equipment required: CGM sensor, transmitter (sends data to a receiver or smartphone), compatible smart device to receive signals, adhesive patches to secure the sensor during activity), and calibration tools if required.
procedure: Insert the sensor under the skin, the typically location is on the arm or abdomen. Connect the transmitter to send glucose readings wirelessly. Sync the device with a smartphone or receiver. Monitor real-time glucose trends before, during, and after exercise. The sensor lifespan is typically 7-14 days.
results: Continuous glucose readings are displayed in real-time and saved to the device. You can review graphs, showing glucose fluctuations, and compare it to activity levels. You can set alerts to notify you when glucose levels are too high or too low.
interpretation of results: Stable glucose levels indicate optimal fueling, while rapid drops suggest energy depletion or poor carbohydrate intake. Spikes may indicate overconsumption or a stress response.
advantages: does not require regular taking of blood samples. CGM provides personalized sports nutrition and performance monitoring. It is beneficial for diabetic athletes managing their glucose levels during exercise. Helps assess the impact of different foods and training intensities.
disadvantages: It can be expensive. Some CGMs require calibration with a blood glucose meter. May cause pain, discomfort, and skin irritation. Data accuracy varies by device and individual. Interpretation of results may be complicated to decipher.
