Objectives:
It is well known that profession athletes often struggle to get adequate restorative sleep. Sleep disturbances have been linked to poor glycemic control in patients with Type 2 diabetes, but this relationship is unknown in well-trained athletes.

Conclusions:

The stepwise regression identified a subset of six objective CPC-sleep metrics that have a significant relationship with a1c: unstable sleep, wake after sleep onset, sleep latency, stable sleep, Fragmentation (elevated low frequency coupling broad band; (eLFCBB) and Periodicity (elevated low frequency coupling narrow band;eLFCNB).

Practical Significance:

This study shows that a two-step, screening process that includes both subjective and objective measures of sleep dysfunction can be used to flag potential issues in well-trained athletes.
