| Abstract |
This research aimed to explore the effects of intermittent hypoxic exposure (IH) with or without exercise on lung function, body composition, lipid profile, haematological variables, and a 6-min walk in people with three cardiovascular risk factors (hypertension stage I, hyperlipidemia, and obesity). Thirty participants were randomly allocated into 3 groups: a control group (CON, n=11) received no training, an intermittent hypoxic exposure during rest group (IHR, n=9), and an intermittent hypoxic training group (IHT, n=10) who combined IH with walking on a motorized treadmill. Both IHR and IHT performed 8 sessions of 3-min of hypoxic breathing
(14% O2) alternated with 3-min of normoxic breathing (21% O2) for 48-min per day, twice a week, for 6 consecutive weeks. All participants were measured before and after 6 weeks of the experimental period.
After training, IHR group significantly increased vital capacity (p=0.038) and forced vital capacity (p=0.025) compared to baseline. Similarly, compared to baseline, participants in the IHT group revealed significantly increased vital capacity (p=0.030), forced vital capacity (p=0.031), and forced expiratory volume in 1 second (p=0.042). Compared to CON, only IHT showed a significant increase in forced vital capacity of 8.6 ± 4.5% (p=0.034) and forced expiratory volume in 1 second of 7.0 ± 3.9%, (p=0.033) after 6 weeks. Both the IHR and IHT participants demonstrated a significantly increased 6-minute walk distance (p=0.048 and p=0.004, respectively) compared to CON. The study demonstrated that IH programs can improve lung function and cardio-pulmonary fitness which indicates that IH with or without exercise improves some cardiopulmonary functions in at risk patients.
