20.500.12556/DKUM-87970 Vpliv joge v nosečnosti na variabilnost srčne frekvence in sinhronizacijo srčno-žilnega sistema z dihanjem po izpostavljenosti stresu Effect of Prenatal Yoga on Heart Rate Variability and Synchronization of the Cardiovascular System With Breathing After Exposure to Stress Vadba joge v nosečnosti bi lahko pozitivno vplivala na potek nosečnosti preko delovanja na avtonomni živčni sistem nosečnice. Namen raziskave je bil ovrednotiti vpliv vadbe joge v nosečnosti na avtonomno živčevje z meritvami variabilnosti srčne frekvence (HRV) in kardiorespiratorne sinhronizacije. Vključili smo 69 nosečnic: 33 jih je redno vadilo jogo in 36 kontrol. Trikrat tekom nosečnosti smo opravili meritve HRV in faznih kardiorespiratornih sinhronizacijskih indeksov. Meritve smo opravili pred in po vadbi joge (ali 30-minutnem sprehodu v kontrolni skupini) v mirovanju ter med in po testu pomnjenja (mentalnemu stresu). Za statistično analizo smo uporabili 2x3x2 tri-smerno analizo variance. Statistično značilnost smo določili pri p<0,05. Analiza HRV je pokazala povečane vrednosti HRV kazalcev, kar nakazuje na povečano parasimpatično aktivnost v mirovanju ter med in po izpostavljenosti stresu pri nosečnicah, ki so vadile jogo (vse p vrednosti <0,01). Statistično pomembnih razlik v kardiorespiratorni sinhronizaciji med skupinama ni bilo. Vadba joge v nosečnosti je povezana z višjo parasimpatično aktivnostjo, ki se kaže s povišanimi kazalci HRV v mirovanju ter ob akutnem stresu. Ob redni vadbi ti učinki vztrajajo skozi celotno nosečnost. Yoga could improve pregnancy outcomes through its effects on the autonomic nervous system. The objective was to analyse the impact of prenatal yoga on autonomic nervous activity using hearth rate variability (HRV) and cardio-respiratory synchronization measurements. We included 69 healthy pregnant women (33 in the yoga group and 36 controls). Measurements of HRV parameters and phase cardio-respiratory synchronization indices were performed three times during pregnancy at rest and following mental challenge before and after yoga (or 30-min walk in the control group). A 2x3x2 three-way analyses of variance was used for statistical comparison of the two study groups (p<0.05 significant). Shifts towards parasympathetic dominance at rest and during/following acute mental stress were found with increased HRV parameters (all p values < 0.01). We found no significant differences between groups in terms of cardio-respiratory synchronization. Regular prenatal yoga was associated with increased HRV suggesting enhanced parasympathetic activity at rest persisting throughout pregnancy. Regular prenatal yoga practice was also associated with a significantly reduced sympathetic response to mental challenge and quicker recovery after acute psychological stress. joga nosečnost variabilnost srčne frekvence kardiorespiratorna sinhronizacija mentalni stres yoga pregnancy heart rate variability cardio-respiratory synchronization mental stress true true false I.
