The effect of 6 weeks HIIT training in the conditions of hypoxia and normoxia on liver enzymes levels and lipid profiles in overweight women

The aim of this study was to evaluate the effect of 6 weeks HIIT training in the conditions of hypoxia and normoxia on liver enzymes levels and lipid profiles in overweight women. Subjects consisted of twenty inactive overweight women that were randomly and equal assigned into two groups, HIIT training under normoxia conditions (age: 27.70 ± 3.164 and BMI: 26.2 ± 91.064) and HIIT training under hypoxia conditions (age: 27.20 ± 3.32 and BMI: 27.1 ± 36.49). Both of groups performed HIIT training for six weeks and three times a week with intensity of 90% Peak oxygen consumption. Blood samples were obtained 48 hours before and after six weeks of HIIT training. Data was statistically analyzed by dependent and independed t-test, with a 0.05 significance level. The findings showed that the level of aspartate aminotransferase in pretest and posttest of both groups decreased significantly, but the levels of alanine aminotransferase, total cholesterol and low density lipoprotein only in the hypoxia group significantly decreased. Therefore HIIT training in hypoxic conditions possibly effective in liver health and prevention of diseases associated with obesity and overweight and it's an appropriate training for inactive and obese individuals
