“…It was proven from previous researches that the saliva level of α-amylase decreased significantly and immediately after practicing yoga during all evaluation periods in yoga groups. The duration of night time sleep was significantly longer in the yoga group (18). Yoga postures help stretching and building muscle, and strengthening bones and relaxing the joints.…”

Sub uterine involution is one of the pathological symptoms of the postpartum period, which causes complications. This is indicated by the size of the fundus uterine, which is greater than the normal size and elongated outflow of lochia. One of the non-pharmacological methods for preventing sub uterine involution is postpartum yoga which focuses on physical and breathing exercises, strengthening of the pelvic floor muscles, and relaxation of autosuggestions. The study aimed to analyze the effectiveness of postpartum yoga on uterine involution. A quasi-experimental, pre-test and post-test with the control group was applied in this study. Thirty-eight postpartum women received postpartum yoga as the intervention group. The control group was comprised of 19 women. The gain score of uterine involution in the intervention group was 9.14 ± 1.27 and in the control group 7.20 ± 1.11. The Cohen’s effect size test is 1.63. The result of the mann whitney test showed that there was a significant difference between the intervention group and the control group with p value 0,000. The result of determination (R Square), postpartum yoga had an effect of 40.3% on uterine involution after being controlled simultaneously with parity, frequency of breastfeeding, and anxiety. Postpartum yoga is effective to strengthen the uterine muscles, facilitate blood circulation, and stimulate neurohormonal so it could accelerate uterine involution. Further studies could measure of fundus uterine daily. Future researchers can develop postpartum yoga research with other variables such as anxiety, urinary incontinence, quality of life for postpartum women, and hormonal variables including oxytocin, endorphins, and cortisol.

“…In one such study, pregnant women attending prenatal yoga classes at gestational ages 20-23 weeks, 28-31 weeks, and 36-40 weeks, provided saliva samples before and after attending each class. The authors found that sAA levels after each yoga session were significantly lower than the sAA values obtained at the beginning of the class and that this effect was consistent across all gestational ages [38]. Another study similarly found that mean sAA values decreased significantly in pregnant women after each of the two yoga classes attended, at 27-32 as well as at 34-37 gestational weeks [39].…”

Salivary Alpha-Amylase as a Biomarker of Stress in Behavioral Medicine

2020

View full text Add to dashboard Cite

In recent years, research in behavioral medicine has become increasingly focused on understanding how chronic and acute exposure to stress impacts health outcomes. During stress, the body's physiological stress systems are activated. These systems closely interact with the immune system and are, thus, importantly implicated in the onset and maintenance of disease states. While much of the research in behavioral medicine that has investigated the effects of stress on disease has focused on the role of the hypothalamic-pituitary-adrenal axis and its downstream biomarker, cortisol, it is evident that the autonomic nervous system (ANS) also plays a crucial role in both the biological stress process and the manifestation and maintenance of stress-related symptoms. In recent years salivary alpha-amylase (sAA) has emerged as a valid and reliable marker of ANS activity in stress research and is therefore an important biomarker to consider in behavioral medicine. In this commentary, we will highlight research relevant for behavioral medicine that has utilized sAA measurements, both basally, and in response to stress, to examine ANS function in clinical populations. We will additionally summarize findings from studies that have examined the effects of various targeted interventions on changes in sAA levels. Through this, our aim is to present evidence that sAA can serve as a feasible biomarker of ANS (dys)function in health and disease. To this end, we will also highlight important methodological considerations for readers to keep in mind when including sAA assessments in their own studies. The overarching goal of this brief commentary is to highlight how a multidimensional approach toward physiological stress measurement can allow researchers to develop a better understanding of physical health and disease states.

Background: Yoga is a popular mind-body medicine frequently recommended and to pregnant women. Gaps remain in our understanding of core components of effective pregnancy yoga programmes. This review and meta-analysis examined the characteristics and effectiveness of pregnancy yoga, incorporating the FITT (frequency, intensity, time/duration and type) principle of exercise prescription in the analysis. Methods: The following electronic databases were searched: MEDLINE, PsycINFO, EMBASE, CINAHL, WHOLiS, AMED, ScieLo, ASSIA and Web of Science. Randomised control trials and quasi-experimental studies examining pregnancy yoga interventions were eligible for inclusion. Covidence was used to screen titles, abstracts, and full text articles. Outcomes of interest were stress, anxiety, depression, quality of life, labour duration, pain management in labour and mode of birth. The Cochrane Collaboration’s Risk of Bias Assessment tool was used to assess methodological quality of studies and GRADE criteria (Gradepro) evaluated quality of the evidence. Meta-analysis was performed using Revman 5.3. Results: 678 citations were retrieved, 24 studies met inclusion criteria. 22 studies with 1826 pregnant women were included for meta-analysis. Applying per-protocol analysis and a random effects model, the pooled standardised mean difference (SMD) for depression (-0.53; 95% CI: -1.04 to -0.02, P=0.04), anxiety (-0.82; 95% CI: -1.64 to -0.01; p=0.05), perceived stress (-1.03; 95% CI: -1.55 to -0.52; p<0.0001) and physiological stress (-0.24; 95% CI: -0.52 to 0.04, P=0.09) supported a statistically significant beneficial effect of pregnancy yoga interventions for anxiety, depression and perceived stress. Duration of labour was shorter (MD= -116.96; 95% CI -163.36 to -70.56, P<0.00001) and normal vaginal birth rates were higher in the yoga group (OR 2.72; 95% CI 1.26-5.90, p=0.01). The quality of evidence (GRADE) was low to very low for all factors. Twelve or more yoga sessions delivered weekly/bi-weekly had a statistically significant impact on mode of birth, while twelve or more yoga sessions of long duration (>60mins) had a statistically significant impact on perceived stress. Yoga sessions had a statistically significant impact on anxiety while yoga therapy had a statistically significant impact on depressionConclusion: The evidence supports previously cited positive effects of pregnancy yoga on anxiety, depression, perceived stress, normal vaginal birth and shorter duration of labour.

Effects of maternity yoga on the autonomic nervous system during pregnancy

Abstract: Our results suggest that practicing yoga activates the parasympathetic nervous system during the third trimester of pregnancy, consolidating sleep during the night and decreasing α-amylase levels, which indicates reduced stress.
