The Effect of Yoga and Pelvic Floor Muscle Exercise on Sexual Function and Sexual Self-esteem of Reproductive-age Women: A Randomized Clinical Trial.

Sexual function is a part of sexual health which is an important aspect of the quality of life. Physical activity is one of the healthiest activities that can effectively reduce the risk of sexual disorders. Therefore, this study was conducted with the aim of evaluating the effect of yoga and pelvic floor muscle exercises on the sexual function and sexual self-esteem of reproductive-age women. This randomized clinical trial study was conducted from September to December 2023 on 46 women of reproductive age working in the Shahrekord University of Medical Sciences and its affiliated health centers. Multi-stage cluster sampling was used to select the subjects; later, they were randomly divided into two intervention groups A (N=21) and B (N=25). Participants in intervention groups A and B performed pelvic floor muscle exercises at home using an educational pamphlet 3 times a week for 6 weeks, with 3 times a day repetition. In addition, women in the intervention group A participated in a yoga training program for 2 sessions per week for 6 weeks. Data collection tools included a demographic information form, the Female Sexual Function Index, and Sexual Self-Esteem Inventory for women. Questionnaires were completed by both groups before, immediately, and one month after the intervention. The data were analyzed using the chi-square test, fisher's exact test, independent two-sample t-test, repeated measures test, and analysis of covariance in SPSS software version 16. A significance level of less than 0.05 was considered. The results showed no statistically significant difference between the two groups in sexual function (P=0.21) and sexual self-esteem (P=0.22) scores before the intervention. Also, the results showed no statistically significant difference between the two groups in terms of sexual function (P=0.35) and sexual self-esteem (P=0.59) scores one month after the intervention. However, the mean score of the sexual function index immediately after intervention showed a statistically significant difference between the intervention groups A (31.43±3.76) and B (29.41±2.38) (P<0.001). The mean score of the sexual self-esteem immediately after the intervention showed a statistically significant difference between the intervention groups A (181.19±19.90) and B (171.32±15.02) (P<0.001). Adding yoga exercises to pelvic floor muscle exercises can improve the sexual function and sexual self-esteem of women at their reproductive age. Trial Registration Number: IRCT20100524004015N1.

Effects of Surya Namaskar yoga on perceived stress, anthropometric parameters, and physical fitness in overweight and obese female university students: A randomized controlled trial

Background: Stress and sedentary lifestyles negatively impact the physical fitness of overweight and obese female university students. Physical activity has been shown to promote psychological as well as physical wellness. However, the effects of Surya Namaskar (SN) yoga on stress and physical fitness remain unclear. Objective: This study aimed to compare the physical fitness, anthropometric measures, and perceived stress between the SN yoga training program group and the control group. Methods: In a randomized controlled study, 44 overweight and obese female university students participated. For 8 weeks, the exercise group received training in SN yoga, whereas the control group was not permitted to participate in any form of exercise. At baseline and after 8 weeks of training, all participants completed the Thai Perceived Stress Scale-10 (T-PSS-10), and assessed the body mass index (BMI), waist–hip ratio, body fat percentage, maximum oxygen consumption (VO2max), and muscle strength and flexibility. We used the dependent t-test or Wilcoxon sign rank test to examine the differences between the T-PSS-10 and physical fitness within each group. The statistical differences of all parameters between the two groups were compared using an independent t-test or a Mann–Whitney U test. A p-[Formula: see text] was considered statistically significant. Results: Compared to the baseline, the SN yoga group’s post-training period had a significant increase ([Formula: see text]) in forward back flexibility, hand grip strength, leg strength, and VO2max, while a significant decrease ([Formula: see text]) in T-PSS-10 scores and BMI. In addition, we found a significant difference between the both groups in forward back flexibility and T-PSS-10 scores in the post-training period ([Formula: see text] and [Formula: see text], respectively). Conclusion: This study’s findings demonstrated that SN yoga is a useful exercise for enhancing overweight and obese female university students’ perceived stress scales and physical fitness.

The impact of yoga on successful aging based on the selection, optimization, and compensation model in elderly women: A quasi-experimental study.

To investigate the impact of yoga on successful aging based on the selection, optimization, and compensation model in elderly women. Quasi-experimental study. Seniors' meeting points and parks and clubs for the old age pensioners of the ministry of education, ministry of healthcare, and the oil corporation in Shiraz, Iran. 68 elderly women within the age range of 60-86 years were divided into a yoga and a control group. The subjects in both groups were asked to complete the selection, optimization, and compensation model questionnaire before and after the intervention. Successful aging was measured using the selection, optimization, and compensation questionnaire. The yoga training program was implemented in 1-h sessions twice a week for eight weeks. After eight weeks of yoga training, the results showed a significant difference between the pretest and posttest successful aging total scores of the yoga group (P=.005). However, the difference between the yoga and control groups' posttest mean total scores was not significant (P=.601). Based on the results, it seems that yoga training can improve successful aging. Thus, yoga is recommended as an inexpensive and entertaining method.

Postural stability and flexibility responses of yoga training in women: Are improvements similar in both sexes?

The researchers’ aim is to examine the postural stability and flexibility responses of yoga training in women. The authors conducted the yoga training program 2 days a week and they assessed flexibility using the sit and reach test, trunk hyperextension test and trunk lateral flexion test. The researchers measured static and dynamic balance employing the device and database system. Then, the authors repeated all assesments were at the end of the first, the fifth and the tenth sessions. As a result of this study, the researchers revealed that the male participants had significantly poorer results in a single parameter (longitudinal sway) when compared with the female group, but the groups were statistically equivalent in this parameter after the first yoga training session. The authors also revealed that yoga was effective in improving flexibility among healthy young adults of both sexes, although the males showed greater improvement than females in the flexibility results.

Effectiveness of yoga training programs to reduce depression and improve resilience of single mothers.

Single mothers are vulnerable to mental health such as depression, but emotional support is insufficient. Yoga is known to be effective in reducing negative emotions and promoting resilience. This study was conducted in order to verify the effectiveness of yoga training programs in reducing depression and improving the resilience of single mothers. Participants in the study included 20 single mothers who belonged to the Single Mothers Association, who were randomly assigned to training (n=10) and nontraining (n=10) groups. The yoga training program for single mothers consisted of Asana yoga, meditation, and mind expression through expert meetings; a total of eight sessions were conducted once a week for 120 min. Testing for depression and resilience was performed before and after the program in order to verify the effectiveness of the program. According to the results of the study, depression in single mothers who participated in the yoga training program was significantly decreased, and resilience was significantly increased. Therefore, the effectiveness of the yoga training program in lowering the depression of single mothers and improving resilience was confirmed. In the future conduct of many studies will be required in order to help the mental health of single mothers.

The participants received 60 30-minutes sessions of the yoga training program. Students will be guided to practice 9 yoga exercises, including greetings, breathing exercises, head and neck, arms and shoulders, spine, legs, rest, meditation, and closing. The results of the analysis showed that there were significant differences between pre and post-test attention and imitation abilities in subjects (sig. (2-tailed) &lt; 0.05). The present study demonstrated that 12 weeks of yoga is effective in improving the attention and imitation abilities of children with intellectual disabilities.

Effect of Yoga on Clinical Outcomes and Quality of Life in Patients With Vasovagal Syncope (LIVE-Yoga).

This study aims to determine the impact of yoga as an adjunct to standard therapy versus standard therapy alone on the symptomatic burden in patients with recurrent vasovagal syncope (VVS). There is a significant reduction in the quality of life (QoL) of patients with recurrent VVS. Existing management therapies have been largely ineffective. Recent trials have demonstrated the efficacy of yoga in diseases with autonomic imbalance, suggesting its possible utility in VVS. Patients with recurrent VVS were randomized to receive either a specialized yoga training program in addition to current guideline-based therapy (intervention arm, group 1) or current guideline-based therapy alone (control arm, group 2). The primary outcome was a composite of the number of episodes of syncope and presyncope at 12months. Secondary outcomes included QoL assessment by World Health Organization Quality of Life Brief Field questionnaire (WHOQoL-BREF) scores and Syncope Functional Status Questionnaire scores at 12months, head up tilt test, and heart rate variability at 6weeks. A total of 55 patients underwent randomization. The mean number of syncopal or presyncopal events at 12months was 0.7 ± 0.7 in the intervention arm compared to 2.52 ± 1.93 in the control arm (P < 0.01). In the intervention arm, 13 (43.3%) patients remained free of events versus 4 (16.0%) patients in the control arm (P = 0.02). QoL at 12months showed significant improvement of all Syncope Functional Status Questionnaire scores and 2 domains of WHOQoL-BREF scores (P < 0.05). Yoga as adjunctive therapy is superior to standard therapy alone in reducing the symptomatic burden and improving QoL in patients with recurrent VVS.

The Impact of Yoga on Inspiratory Muscle Performance in Veterans with COPD: A Pilot Study.

Chronic obstructive pulmonary disease (COPD) causes respiratory muscle weakness that leads to disabling dyspnea and poor functional performance. Therapies are often geared to improve inspiratory muscle performance. Yoga has been shown to improve exercise capacity, quality of life, and some pulmonary function measures in COPD, but little research has examined the effects of yoga training on inspiratory muscle performance. The purpose of this study was to investigate the effects of yoga training on inspiratory muscle performance in military veterans using the Test of Incremental Respiratory Endurance (TIRE). A prospective pilot study examined a 6-week yoga training program consisting of asana (poses) and pranayama (controlled breathing). Subjects had baseline inspiratory muscle weakness. The TIRE measured inspiratory muscle performance via the PrO2 device, providing maximal inspiratory pressure, sustained maximal inspiratory pressure, and inspiratory duration. Secondary measures included 6-minute walk distance, St. George Respiratory Questionnaire, Hospital Anxiety and Depression Scale, and spirometry. Mean age and BMI of subjects were 67 ± 3.6 years and 20.7 ± 3.3, respectively. The majority of subjects had severe (28.7%) or very severe (57.1%) COPD. Statistically significant improve m e n t s were seen in maximal inspiratory pressure (39.0 ± 14.1 cmH2O to 56.4 ± 20.6 cmH2O) and sustained maximal inspiratory pressure (244.1 ± 100.6 PTU to 308.1 ± 121.2 PTU). No statistically significant improvements we re observed in 6-minute walk distance, St. George Respiratory Questionnaire, Hospital Anxiety and Depression Scale, or spirometry. Yoga training has the potential in improve inspiratory muscle performance in veterans with severe to very severe COPD who present with inspiratory muscle weakness. This is of importance because improving inspira-tory muscle performance has been shown to improve COPD outcomes.

Evaluating the Use of Mindfulness and Yoga Training on Forensic Inpatients: A Pilot Study.

Forensic inpatients (i. e., individuals found not responsible for a criminal offense on account of mental illness) represent an often marginalized and difficult-to-treat population. This has led to the need for research exploring the effectiveness of novel interventions. A Canadian forensic hospital has developed an 8-weeks mindfulness and yoga training program (MTP). This pilot study examined the potential effects of this program on patients' mindfulness, stress, and use of cognitive and emotion regulation strategies. A sample of 13 forensic inpatients (male = 92%) participating in the MTP program completed self-report measures assessing dispositional mindfulness, perceived stress, and use of cognitive emotion regulation strategies at baseline, post-intervention, and a 3-months follow-up. Repeated measure ANOVAs found a significant increase in the describe facet of mindfulness (p = 0.03) with a large effect size (ηp2 = 0.26) and a significant decrease in stress (p = 0.003) with a large effect size (ηp2 = 0.39). Pairwise comparisons revealed medium to large significant changes between baseline and post-intervention for both the describe facet (p = 0.03, Hedge's g = 0.55) and stress (p = 0.003, Hedge's g = 0.70). However, comparisons were insignificant between baseline and follow-up. No significant main effects were found on the use of cognitive emotion regulation strategies. This pilot study offers preliminary support for the use of the MTP as an adjunctive therapy in forensic inpatient treatment. Further investigation is needed into the long-term impacts of this training.

Yoga and Aerobic Dance for Pain Management in Juvenile Idiopathic Arthritis: Protocol for a Pilot Randomized Controlled Trial.

BackgroundJuvenile idiopathic arthritis (JIA) is one of the most common types of arthritis among children. According to JIA guidelines for physical activity (PA), structured PA interventions led to improved health outcomes. However, many PA programs, such as yoga and aerobic dance, have not been studied in this population despite being popular among youth. Web-based PA programs could provide patients with accessible and affordable interventions.ObjectiveThe primary aims of the proposed pilot randomized controlled trial (RCT) are to examine (1) the feasibility of conducting a full-scale RCT to evaluate the effectiveness of two popular types of PA: a yoga training program and an aerobic dance training program, in female adolescents (aged 13-18 years) with JIA compared with an electronic pamphlet control group; and (2) the acceptability of these interventions.MethodsA three-arm prospective randomized open-label study with a parallel group design will be used. A total of 25 female adolescents with JIA who have pain will be randomized in a ratio of 2:2:1 to one of the 3 groups: (1) online yoga training program (group A: n=10); (2) online aerobic dance training program (group B: n=10); and (3) electronic pamphlet control group (group C: n=5). Participants in groups A and B will complete 3 individual 1-hour sessions per week using online exercise videos, as well as a 1-hour virtual group session per week using a videoconferencing platform for 12 weeks. Participants from all groups will have access to an electronic educational pamphlet on PA for arthritis developed by the Arthritis Society. All participants will also take part in weekly online consultations with a research coordinator and discussions on Facebook with participants from their own group. Feasibility (ie, recruitment rate, self-reported adherence to the interventions, dropout rates, and percentage of missing data), acceptability, and usability of Facebook and the videoconferencing platform will be assessed at the end of the program. Pain intensity, participation in general PA, morning stiffness, functional status, fatigue, self-efficacy, patient global assessment, disease activity, and adverse events will be assessed using self-administered electronic surveys at baseline and then weekly until the end of the 12-week program.ResultsThis pilot RCT has been funded by the Arthritis Health Professions Association. This protocol was approved by the Children’s Hospital of Eastern Ontario Research Ethics Board (#17/08X). As of May 11, 2020, recruitment and data collection have not started.ConclusionsTo our knowledge, this is the first study to evaluate the effectiveness of yoga and aerobic dance as pain management interventions for female adolescents with JIA. The use of online programs to disseminate these 2 PA interventions may facilitate access to alternative methods of pain management. This study can lead to a full-scale RCT.International Registered Report Identifier (IRRID)PRR1-10.2196/12823

Effects of Hatha Yoga on Cardiac Hemodynamic Parameters and Physical Capacity in Cardiac Rehabilitation Patients.

The purpose of the present study was to assess the effect of hatha yoga training that was added to the standard cardiac rehabilitation (CR) program on the cardiac hemodynamic parameters and physical capacity of patients with ST-elevation myocardial infarction (STEMI). The study included 70 male patients aged 45-65 yr with STEMI who were treated by angioplasty. Patients were randomized to standard CR (control group) versus standard CR plus hatha yoga (experimental group). The training program lasted for a total of 24 d for each patient, with day 1 and day 24 used for medical examinations (electrocardiogram, spiroergometric submaximal treadmill test, and echocardiography). The remaining 22 d consisted of the actual training. After the CR program the spiroergometric stress test parameters and left ventricular ejection fraction (LVEF) improved in both the experimental and control groups. The most notable changes in echocardiography parameters and physical capacity were in the experimental group. The results showed significant main effect over time, a time-versus-group interaction in LVEF, the duration of the test, and peak oxygen uptake, and a time-versus-group interaction in metabolic equivalents (METs). We also noted the improvement of left ventricular end-diastolic diameter, left ventricular end-systolic diameter, and heart rate over time. The results revealed better effectiveness in the CR program with a modified hatha yoga training program. Hatha yoga training could be recommended as an adjunct to standard CR.

Effects of yoga on exercise capacity in patients with lymphangioleiomyomatosis: a nonrandomized controlled study

ObjectiveTo evaluate the effects of yoga on exercise capacity and quality of life in patients with lymphangioleiomyomatosis (LAM), a rare cystic lung disease in women.Patients and methodsThis was a nonrandomized, controlled study conducted in Beijing, China (August 27, 2017 – April 26, 2018). Twenty-six participants were allocated to the intervention (yoga) group (n = 13) or control group (n = 13). The yoga intervention involved a 24-week program of yoga class training for 90 min once a week and no fewer than 2 at-home sessions per week (at least 15 min per session). The 6-min walking distance (6MWD), lung function, serum vascular endothelial growth factor-D (VEGF-D) levels, quality of life, and symptoms of anxiety and depression were measured at baseline, 12-week and 24-week follow-up. An incremental cardiopulmonary exercise test was conducted at baseline and the 24-week follow-up.ResultsEleven patients completed the yoga training program. The yoga group exhibited improvements in the following outcomes versus those of the control group: 6MWD (+ 55 ± 29 m vs + 18 ± 49 m, P = 0.04), anaerobic threshold (3.4 ± 2.4 ml/min/kg vs 1.6 ± 1.4 ml/min/kg, P = 0.035) and peak work load (11.7 ± 14.6 W vs 0.2 ± 9.1 W, P = 0.027). There was no significant difference in peak oxygen consumption (VO2peak), lung function, VEGF-D level, and quality of life between the yoga and control groups. No adverse effects were found in the yoga group.ConclusionYoga is a feasible and safe intervention for pulmonary rehabilitation and potentially improves exercise capacity in patients with LAM.Trial registration(Clinical trial registration number at www.chictr.org.cn: ChiCTR-OON-1701274)
