What was the purpose of this research?
- Although there is much research on the physiological and nutritional demands of elite cyclists, our understanding of these factors in the context of athletes with type 1 diabetes is much less established.
What did we research?
- This paper explored the dietary, bodily and glycemic demands of a 9-day training camp of 16 male professional cyclists with type 1 diabetes.
- To do this, the Research Team monitored food intake, glucose (using Dexcom G6) and a number of variables related to the physical demands of the training rides (e.g. distance covered, speed, elevation, temperature, energy expenditure).
What did we find?
- The athletes spent the majority of their time during the training sessions in target glycemic range (4-10 mmol/l).
- However, following daily, strenuous cycling training, there was a tendency for riders to spend a greater amount of time with low glucose levels during the night.
- If the riders experienced hypoglycemia during the night, this was associated with increased risk of hypoglycemia the following day.
