INS and type 1 diabetes mellitus: Ten adults with T1D (3 men, 7 women) were recruited, however two participants were excluded due to protocol violations; one did not meet the inclusion criteria after commencing test sessions (HbA1c above inclusion criteria) and the other participant had given a substantial insulin correction dose 3 h prior to the session, which had lowered glycemia by ~10 mmol/L leading up to the start of the session.
