Arms Assigned Interventions
Experimental: Hyperbaric oxygen therapy
Effect of 2 hrs HBO therapy on muscular insulin sensitivity and resistance in obesity and type 2 diabetes mellitus
Procedure: HBO therapy
Effect of 2 hrs HBO therapy on muscular insulin sensitivity and resistance in obesity and type 2 diabetes mellitus
Other Names:
  • oxidative stress
  • antioxidative capacity
Sham Comparator: Hyperbaric room air
Effect of 2 hrs hyperbaric room air herapy on muscular insulin sensitivity and resistance in obesity and type 2 diabetes mellitus
Procedure: Hyperbaric room air
Effect of 2 hrs hyperbaric room air on muscular insulin sensitivity and resistance in obesity and type 2 diabetes mellitus
Other Names:
  • HBO therapy
  • oxidative stress

Detailed Description:

HBO therapy is applied to improve wound healing in diabetic patients with foot ulcera. However, it might induce oxidative stress as well as improve antioxidative capacity. The effects on insulin sensitivity in humans and will be tested in the study.
