Is a 12-week home-based functional teletraining for individuals with type 2 diabetes an alternative for blood glucose control?

Background: Virtual or Tele-exercise programs have emerged due to safety concerns of COVID-19 contamination for at-risk groups. However, blood glucose (BG) comparisons concerning in-person and virtual exercise programs need to be scientifically researched. Understanding and monitoring home-based teletraining effects on glycemia is vital for safe management of people with type-2 diabetes (T2DM).

Purpose: To verify a 12-week functional teletraining on the capillary BG and compare it with in-person exercise before the COVID-19 pandemic in people with T2DM.

Methods: T2DM participants underwent tele-exercise during the COVID-19 pandemic. It consisted of functional training (functional resistance training (FRT) for 12 weeks, 2 times a week, ∼60 min). Capillary BG was performed before and after (pre-post) each exercise session. The pre-post ΔBG for each session was considered for statistical analysis. Friedman's test with repetitive measures over time was performed to compare the ΔBG of the teletraining and the results of these participants before the pandemic. The minimum detectable difference was performed to verify clinical ΔBG for each session over the weeks.

Results: Similar responses were seen over time without a statistical time effect after the programs (p = 0.177). A noticeable minimum difference of 24.5 mg/dL was observed in the in-person group post-session in all sessions. The virtual group showed a minimum detectable difference of 21.1 mg/dL post-session with clinical relevance over the 12 weeks.

Conclusion: Despite the teletraining being twice weekly and the in-person program thrice weekly, both exhibited similar outcomes over time, with the virtual program showing significant clinical improvements in BG after each session.
