The present study verified the effects of interval training under hypoxia, a novel exercise modality for health promotion, on autonomic nervous system (ANS) and arterial hemorheological function in healthy women.Twenty Korean women (age: 19-29 [24.85 ± 3.84] years) were equally assigned to normoxic (INT, n = 10; residing normoxia) hypoxic (IHT, normoxia 526 mmHg hypobaric hypoxia) groups. All participants performed 90-min sessions composed 15-min warm-up, 60-min training, cool-down. 10 repetitions using treadmill (5 min corresponding 90-95% maximal heart rate [HR] 1 rest). was 3 days per week 6 weeks. underwent body composition, HR variability, brachial-ankle pulse wave velocity, flow-mediated dilation (FMD), red blood cell (RBC) deformability aggregation, oxygen uptake (VO2max) measurements before after training.There no significant differences composition between IHT group showed improvement ANS (root mean square successive differences, high frequency, low frequency/high frequency ratio), stiffness, endothelial (RBC aggregation), aerobic performance compared with INT (all p < 0.05).In comparison normoxia, hypoxia is effective promoting women.
