Inhaled human insulin is a new alternative to administration by subcutaneous injection. However, the absorption of inhaled insulin may be affected by exercise — this information is important for the diabetic athlete

Research question/s:

Does moderate exercise increase the absorption of inhaled insulin?

Methodology:

Subjects: 12 non-smoking healthy subjects (22.7–36.4 years)

Experimental procedure: All the subjects were screened and then underwent three interventions after inhaling 3.5 mg human insulin via a nebuliser in a random order as follows: no exercise (Con), 30 min exercise (50% VO2max) immediately after inhalation (ExImm), or 30 min exercise starting 30 min after inhalation (Ex30). The study was carried out as a 10 h euglycaemic glucose clamp (5.0 mmol/litre)

Main measures of outcome: Absorption of insulin in first 2 h (% increase from Con), insulin concentration

Main finding/s:

Conclusion/s:
