What Researchers Did
Australian researchers used two methods to measure insulin sensitivity in overweight, non-diabetic men during and after HBOT sessions to determine when the insulin-sensitizing effect begins and how long it lasts.
What They Found
A glucose clamp technique showed a significant 23% increase in insulin sensitivity during the very first HBOT session. However, a different test method (FSIGT) found no significant change in insulin sensitivity during the third session or 24 hours after treatment, suggesting the effect may be acute and method-dependent.
Canadian Relevance
No direct Canadian connection identified. The conflicting results between measurement methods highlight that more research is needed before HBOT can be recommended for metabolic conditions.
Study Limitations
The study enrolled only 9 men per sub-study, used two different protocols, and produced contradictory results, making firm conclusions impossible.
