INS and Hypoglycemia: The aim of the study was to evaluate the effect of combined aerobic and resistance exercise conducted in type 1 diabetic patients in hypoxic conditions on glycemic profile and its stability (with use of an intermittent scanning glucose monitoring system), HbA1c value, frequency and severity of hypoglycemia, VO2max, body weight, waist-to-hip ratio (WHR), body composition (tissue and muscle content), insulin requirements, and the need to replenish carbohydrates during exercise in comparison to the same type of effort in normoxic conditions.
