| Abstract |
The aim of the study was to evaluate the effects of 6 weeks of intermittent hypoxic at rest or plus exercise and long-lasting effects on blood pressure and heart rate variability (HRV) in cardiovascular risk individuals. Thirty combinations of several CVD risks participants: hypertension, hyperlipidemia, and obesity were randomly allocated into 3 groups: the control group (CON, n=11) received no intervention, intermittent hypoxic exposure during rest (IHR, n=9), and intermittent hypoxic training (IHT, n=10) combined with walking on a motorized treadmill at a light to moderate-intensity. Both IHR and IHT have performed 8 sessions of 3 mins of hypoxic breathing alternated with 3 mins of normoxic breathing for 6 weeks. All participants were measured blood pressure and HRV at baseline, at week 6 (POST1), and week 10 (POST2). IHR and IHT showed significantly lower SBP (P < 0.05) compared to CON but not DBP and MAP after IH program. Compared to CON, VLF and LF/HF ratio showed a significantly decreased in only IHT (P < 0.05) at POST1 and VLF remained significantly decreased at POST2. VLF in IHT showed remains significantly lower than IHR at POST2. After IH program, IHT revealed a significantly increased in HF (p < 0.05) compared to CON. HF (n.u.) was a significantly stronger negative correlation with changes in SBP (P < 0.05). IHT showed more effectiveness than IHR. The study suggested this IH program improved SBP and HRV at POST1. An increase in parasympathetic activity may play an important role in SBP reduction seen in this study. |
