Summary

This study looks at 14 people with type 1 diabetes who use the MiniMed 780G insulin pump. They will do a supervised strength training session twice, once with the pump in SmartGuard mode and once with a temporary target setting. The goal is to see which setting keeps blood sugar in a safe range and prevents low blood sugar during and after exercise.
