    Journal: Med Sci Sports Exerc; 2018 Nov; 50(11):2200-2208. PubMed ID: 29923910.
    Abstract:
    PURPOSE: This study aimed to test whether environmental hypoxia could potentiate the effects of exercise training on glucose metabolism and insulin sensitivity. METHODS: Fourteen adolescents with obesity were assigned to 6 wk of exercise training either in normoxic or in hypoxic conditions (FiO2 15%). Adolescents trained three times per week for 50-60 min, including endurance and resistance exercises. Oral glucose tolerance test, blood and morphological analyses, and physical performance tests were performed before and after the training period. RESULTS: After training, hypoxia, but not normoxia, decreased the area under the curve of plasma insulin (-49%; P = 0.001) and glucose levels (-14%; P = 0.005) during oral glucose tolerance test. Decreased plasma triglycerides levels (P = 0.03) and increased maximal aerobic power (P = 0.002), work capacity at 160 bpm (P = 0.002), and carbohydrate consumption during exercise (P = 0.03) were measured only in the hypoxic group. CONCLUSIONS: Hypoxic exercise training was particularly efficient at improving glucose tolerance and insulin response to a glucose challenge in adolescents with obesity. These results suggest that exercise training in hypoxia could be an interesting strategy against insulin resistance and type 2 diabetes development in adolescents with obesity.
