Effects of a complex yoga-based intervention on physical characteristics.

Empirical studies on yoga have shown that regular practice can have a beneficial effect on risk factors of cardiovascular diseases; also, it can decrease body weight, body fat and increase muscle mass. Positive effects on balance and flexibility were also reported. This study evaluated the impact of a 3-month complex yoga-based program, including physical exercises, education, and social support, with a quasi-randomized design in a middle-aged community sample. The intervention group consisted of 46 participants while the passive control group was 29 participants. The intervention group showed a significant increase in core muscle strength and hamstring flexibility and a decrease in body  fat. No significant changes were found concerning risk factors of cardiovascular diseases, body weight, muscle mass, balancing ability, and dietary habits. A 3-month yoga intervention cannot substantially impact the cardiovascular system and body weight control in middle-aged adults.

Acute Musculoskeletal Complaints Vary According to the Perceived Stress Among Hungarian Professional Dancers.

Introduction: Studies showed that professional dance is often associated with a high degree of acute musculoskeletal injuries. These injuries' etiology predominantly describes their biomechanical or other extrinsic factors, but there is a limited number of scientific reports dealing with the perceived stress or mental health status concerning the physical complaints especially, among Hungarian professional dancers. Materials and Methods: In this study, we used validated questionnaires (RESTQ, SEFIP, Mental Health Test) filled out by Hungarian professional female dancers (N = 168) via an online platform anonymously and analyzed statistically. Results: Our findings showed a significantly positive relationship between musculoskeletal complaints and perceived stress, an elevated level of general stress, and a higher level of resilience in this population compared to the general population. Conclusion: Dancers demonstrate a heightened perception of stress; however, they exhibit elevated scores on resilience assessments, indicative of heightened functionality in their daily lives. Stress, per se, may not be directly regarded as a causative factor for acute musculoskeletal conditions, but it could potentially influence the severity of pain sensations and subjective pain levels in the context of existing injuries. Additional investigations are warranted to elucidate the precise mechanisms by which stress exacerbates the pain experience among dancers.

Can Emotional or Physical Abuse Be a Risk Factor of Chronic Musculoskeletal Conditions in Professional Dance?

OBJECTIVE: In professional dance, the injury rate is extremely high and dancers have a great chance to experience at least one injury during their careers. Since the #metoo campaign, many abuse cases showed up in the dance industry, resulting in media coverage. Results indicate that dancers had a significantly higher distribution of post-traumatic stress disorder (PTSD) compared to the broad population. In this study, we investigate pathological dissociation, quantify chronic musculoskeletal conditions and evaluate abusive experiences. METHODS: Questionnaire-based dataset filled out online by Hungarian professional dancers (n = 168). The statistical analysis contains descriptive results, risk assessment, Kaplan Meier curve, and hazard ratios. RESULT: Dancers scored in the pathological dissociation values, reported several cases of emotional and physical abuse, and were represented by elevated chronic musculoskeletal conditions. We found a statistically significant relationship between abusive experiences and musculoskeletal conditions, so as with dissociation. CONCLUSION: We conclude that emotional abuse might be one of the factors in a multifactorial model that plays a role in the pathomechanism of chronic pain, inflammation, and tendinopathy. It is important to raise awareness about the importance of emotional factors of pedagogy and the working atmosphere among professional dancers since it might have a role in higher injury rates.

The effects of a complex yoga-based intervention on healthy psychological functioning.

Background: Yoga based interventions were found to have a positive impact on various indicators of psychological functioning, such as perceived stress, satisfaction with life, positive and negative affectivity. Additionally, such interventions improved bodily or interoceptive awareness and spirituality. Methods: The present study assessed the effects of a 3-month long complex yoga-based intervention compared to a passive control group in a Hungarian community sample. The final sample consisted of 44 intervention (Mage = 47.5, SD = = 8.76) and 29 control participants (Mage = 47.4, SD = 9.47). The aforementioned constructs were measured 1 week before and after the intervention. Results: The intervention reduced participants' perceived stress (p = <0.001, ηp 2 = 0.153) and negative affectivity (p = 0.019, ηp 2 = 0.113), improved spirituality (p = 0.048, ηp 2 = 0.054) and various aspects of interoceptive awareness such as noticing (p = <0.001, ηp 2 = 0.169) attention regulation (p = <0.001, ηp 2 = 0.211), self-regulation (p = 0.002, ηp 2 = 0.190) body listening (p = 0.010, ηp 2 = 0.097), trusting (p = 0.026, ηp 2 = 0.070), but did not impact positive affectivity and satisfaction with life. Conclusion: A 3-months long complex yoga-based intervention has a positive impact on many aspects of healthy psychological functioning.

Avoidance of fitness or sports facilities during a lockdown: Gender and training environment could be protective factors.

The COVID-19 pandemic has swept the world, claiming nearly seven million lives by now. Despite a decline in the mortality rate, in November 2022, the virus-linked death cases still exceeded 500 every day. There is a belief that it is over now, but similar health-crisis situations may re-occur, and therefore it is essential to learn from such human disasters. It is an accepted fact that the pandemic has changed people's lives worldwide. One specifically and significantly affected life domain, especially during the lockdown, is the practice of sports and planned physical activities. Hence, this study examined the exercise practices and attitudes towards attending fitness facilities in 3053 working adults during the pandemic, along with the differences associated with the preferred training environment, including fitness/sports facilities, home, outdoor, or their combinations. The results revealed that women (representing 55.3% of the sample) are more precautious than men. Further, exercise behavior and COVID-19 attitudes broadly vary among people choosing different training venues. In addition, age, exercise frequency, place of exercise, fear of infection, flexibility in training form, and desire to exercise freely are predictors of non-attendance (avoidance) of fitness/sports facilities during the lockdown. These results expand earlier findings to exercise settings, suggesting that women are more precautious than men in the exercise context too. They are also the first to indicate that the preferred exercise environment entails attitudes that shape exercise patterns and beliefs associated with the pandemic differently. Therefore, men and regular fitness center attendees need more attention and special guidance in enforcing legislative prevention measures during a health crisis.

Dimensions of passion and their relationship to the risk of exercise addiction: Cultural and gender differences.

This study was performed to investigate further the two-dimensional aspect of passion and its relationship to the risk of exercise addiction (REA) in nine nations and to clarify the unresolved gender differences. The here reported results stem from the reanalysis of data gathered in three previous empirical studies. The analyses demonstrated that harmonious (HP) and obsessive (OP) passion are two independent, non-interacting predictors of the REA, the prevalence of which was 12.1 % in the current sample that included 1448 people (age = 30.49 ± SD = 11.17 years; 55 % men), who exercised at least three hours per week. Furthermore, the results show that HP and OP could co-exist as a single 'total' or 'true' passion within the individual or in high-low HP and OP proportions, supporting the proposal for one, two-dimensional passion. Indeed, most people at REA demonstrated both high HP and high OP. The weekly amount of exercise was weakly associated with the two dimensions of passion. Relatively specific cultural differences in the REA and OP, but not HP, have emerged. The results also demonstrate that when a minimal weekly volume of training (i.e., 3 h) is a criterion for participant recruitment, no gender differences occur in the REA.

Passion and risk of addiction in experienced female yoga practitioners.

Yoga is a popular leisure activity and health practice worldwide, especially among women. It could become a long-term lifestyle involving passion, but, like other exercises, it may become addictive. While exercise addiction is widely studied, addiction to yoga remains unexplored. In this cross-sectional study, we examined 215 highly experienced women who practiced yoga for at least three years and at least twice weekly. We scrutinized harmonious passion (HP), obsessive passion (OP), risk of exercise addiction (REA), and various yoga-related measures. Only 2/215 (0.93%) of the sample were at REA. Reported HP, OP, feeling guilty when missing a yoga session, and the tendency to practice yoga when injured predicted the REA by accounting for 42% of the variance. Yogis who regularly practiced pranayama (breathing exercises) scored higher on HP, weekly yoga practice, and posting messages on social media than those who never or seldom used breath regulation. Participants choose yoga primarily for health and social reasons. The posting of yoga-related messages on social media was positively related to HP, OP, REA, and frequency of practice. The conclusions of this study are 1) the REA among experienced female yogis is negligible, 2) HP is higher in yoga forms that involve pranayama, 3) yoga practice is primarily related to health and social factors, and 4) a more intense passion for yoga is related to more frequent social media activities.

Exercise Addiction During the COVID-19 Pandemic: an International Study Confirming the Need for Considering Passion and Perfectionism.

Various levels of lockdown due to COVID-19 limit people's habitual physical activity. Individuals addicted to exercise, health-oriented, and team-exercisers could be the most affected. We examined the COVID-19-related changes in exercise volume in 1079 exercisers from eight Spanish-speaking nations based on exercise addiction categories, primary reasons for exercise, and forms of exercise. The COVID-19-related decrease in exercise volume was 49.24% in the sample. The proportion of the risk of exercise addiction was 15.2%. Most (81.7%) of the participants exercised for a health-related reason. These exercisers reported lesser decrease in their exercise volume than those exercising for social reasons. The risk of exercise addiction was inversely related to changes in exercise volume, but after controlling for passion and perfectionism the relationship vanished. The reported effect of COVID-19 on training did not differ between the exercise addiction groups. The findings also confirm that exercise addiction research should control for passion and perfectionism.

Is Weekly Frequency of Yoga Practice Sufficient? Physiological Effects of Hatha Yoga Among Healthy Novice Women.

Beneficial physical and physiological health outcomes of yoga practice are well-supported by empirical data. However, whether weekly frequency of training is sufficient to evoke positive changes, is still an open question. The present intervention study investigated the effects of 10 weekly sessions of beginner level hatha yoga with respect to indicators of physical fitness and physiological markers. 82 young women (mean age of 22.0 ± 3.83 years) participated in the study. The yoga group (N = 49) attended a yoga course consisting of 10 sessions (1.5 h each) on a weekly basis. The control group (N = 33) did not receive any intervention. BMI, body fat percentage, balance (one-leg-stand test with open and closed eyes, functional reach test), flexibility (side bend test, modified sit and reach test) core muscle strength (plank test) as well as resting heart rate (HR), and heart rate variability (HRV) were assessed 1 week before and after the course. Both frequentist and Bayesian analysis showed an improvement in flexibility and balance in the yoga group compared to the control group. The yoga group showed also increased core muscle strength. No changes with respect to BMI, body fat percentage, resting HR and HRV were found. Ninety minute beginner level hatha yoga classes were characterized by 93.39 HR and 195 kcal energy consumption on average. The present findings suggest that weekly setting of a 10-session long hatha yoga training leads to improvements in balance, flexibility and core muscle strength among healthy young women. However, for changes in BMI, body fat percentage, resting HR and HRV longer, and/or more intense interventions are needed.

Effects of a pedometer-based walking intervention on young adults' sleep quality, stress and life satisfaction: Randomized controlled trial.

OBJECTIVE: The purpose of this study was to evaluate the effect of daily walking exercise on sleep quality, perceived stress and life satisfaction. It aimed to investigate the interaction between daily walking exercise and sleep components (sleep quality, sleep latency, sleep duration, sleep disturbance, sleep medication use, and daytime functioning). METHODS: A four-week randomized control trial (RCT) was conducted by assigning 54 research volunteers into two groups randomly. The participants in the intervention group (IG) were asked to carry out a daily aerobic walking exercise (DAWE), and participants in the control group (CG) were requested to maintain a sedentary life style. Sleep quality, perceived stress and life satisfaction were assessed at the baseline and at the end of the intervention. All participants were equipped with Omron HJ-112 pedometer to record their daily exercise and to fulfil a daily diary sheet. RESULTS: By the end of the intervention, 26 out of 54 participants (Mage = 24.96; SD = 5.13) completed the task. There was no statistical significance between the two groups when comparing global sleep quality, stress and life satisfaction. The within group comparison showed positive effect of DAWE on subjective sleep quality (p = 0.05), less sleep medication use (p < 0.05), positive effect on daytime function (p < 0.01) and improved life satisfaction (p = 0.05) after four weeks of intervention. CONCLUSION: Findings suggested that incorporating daily aerobic walking exercise might be beneficial to sleep health. Further studies are suggested to ascertain the pedometer-based daily walking exercise's long-term effects and to unfold the biological mechanisms leading to its sleep quality improvement effect.

Attitudes toward COVID-19 and stress levels in Hungary: Effects of age, perceived health status, and gender.

The aim of this report is to provide a picture about Hungarians' attitudes and behaviors 1 month after the first COVID-19 case was confirmed in Hungary. Based on survey data from 1,552 adults that were collected in mid-April 2020, it appears that Hungarians agree with and follow the preventive measures of the government. There are, however, differences between 3 age groups (i.e., 18-30, 31-59, and 60+ years), people with different perceived health status (i.e., good, average, and below average), and the genders. In Hungary young people, those with perceived average or below-average health, and women report the most stress during the early phase of the COVID-19 period.

Could attitudes toward COVID-19 in Spain render men more vulnerable than women?

The COVID-19 pandemic affects the whole world. Spain is 5th in the world and 3rd in Europe with the largest number of diagnosed cases. Spanish citizens' attitudes are important in controlling the pandemic. This research assessed attitudes of Spaniards toward COVID-19 in two studies. One (n = 64) was conducted in a shopping centre in Madrid and another (n = 640) online. The results of both studies suggest that women in Spain have a 'more responsible' attitude toward the COVID-19 than men. Young adults (18-25 years) scored lower on compliance with safety measures and perceived need to stay home than older adults. In Study 1, level of compliance, knowing someone at risk, and knowing someone infected predicted 31.2% of the variance in the perceived need to stay home. In Study 2, personal concern, level of compliance, keeping distance from others, and perceived social alarm predicted 28.5% of the variance in perceived need to stay home. Regardless of age and/or gender, Spanish people's personal concern about COVID-19 was less than their perceived social alarm about it. These results might help policy makers in considering public attitudes which could play an important role in controlling the current, and possibly a second, wave of COVID-19.

Inhaled peppermint, rosemary and eucalyptus essential oils do not change spirometry in healthy individuals.

Essential oils of herbal origin are widely used in the treatment of diseases of the upper and lower respiratory tract primarily due to their antibacterial and antiviral effects. Menthol, the major component of the essential oil of mint (Mentha) species, exhibits antispasmodic activity, which might result in improved lung function. In a randomized experiment, 106 healthy participants received nebulized peppermint, eucalyptus, or rosemary essential oil for 15 min or no treatment (control). None of the essential oils had an impact on the measured spirometric variables (forced vital capacity, peak expiratory flow, the ratio of the volume of air forcibly blown out in the first second to forced vital capacity). Participants' expectations regarding the effects of essential oils did not affect their objective performance, however, they predicted perceived (subjective) changes. Perceived and measured changes were not connected with each other. In conclusion, inhaled rosemary, peppermint, and eucalyptus essential oils' subjective (perceived) effect on spirometry is mediated at least partly by expectations.

An in-situ investigation of the acute effects of Bikram yoga on positive- and negative affect, and state-anxiety in context of perceived stress.

BACKGROUND: Bikram yoga is a relatively new, but an increasingly popular form of exercise. Its health benefits were demonstrated on physical and psychological measures. AIMS: The current field study tested the acute effects of Bikram yoga on practitioners' positive-/negative-affect and state-anxiety, and their link to the self-perceived stress, in Bikram yoga participants. METHOD: Field study, within-participants design, testing perceived stress and its relation to changes in positive-/negative-affect and state-anxiety in 53 habitual Bikram yoga participants. RESULTS: Statistically significant positive changes emerged in all three psychological measures after the 90-min Bikram yoga session. The decrease in negative-affect and state-anxiety were significantly and positively related to the perceived stress. Estimated effort was unrelated to the magnitude of the changes recorded in the psychological measures. Heart rates and self-report measures indicated that physically Bikram yoga is only mildly challenging. CONCLUSIONS: The findings illustrate that, independently of the physical effort, Bikram yoga is a new mild form of exercise that reduces negative-affect and state-anxiety, and the reduction is directly related to the perceived stress. Therefore, Bikram yoga appears to be beneficial for all practitioners, but even more so for the individuals who experience substantial stress in the daily life.

Calcineurin-inhibition Results in Upregulation of Local Renin and Subsequent Vascular Endothelial Growth Factor Production in Renal Collecting Ducts.

BACKGROUND: Tacrolimus (Tac) and Cyclosporine A (CyA) calcineurin inhibitors (CNIs) are 2 effective immunosuppressants which are essential to prevent allograft rejection. Calcineurin inhibitors are known to be nephrotoxic. However, the precise mechanism of nephrotoxicity is not fully understood. In this study, we investigated the in vivo effects of CNIs on the local renal renin-angiotensin system in the collecting duct (CD). METHODS: Three-week-old mice were treated with either vehicle, CyA (2 mg/kg per day), Tac (0.075 mg/kg per day), CyA + Aliskiren (25 mg/kg per day), or Tac + Aliskiren for 3 weeks. Serum creatinine was measured. Renin and vascular endothelial growth factor (VEGF) contents in CD were evaluated with flow cytometry and multiphoton microscopy. The diameter of vessels was assessed with multiphoton microscopy, and the amount of renal collagen was determined by real-time polymerase chain reaction and Masson staining. RESULTS: The elevated level of serum creatinine in CNI groups was abolished by Aliskiren. Flow cytometric analysis found elevated renin content in principal cells, which was prevented by Aliskiren. This result was further confirmed with multiphoton microscopy. The VEGF content in CD correlated with reduced capillary diameter and with the formation of fibrotic islands. CONCLUSIONS: Calcineurin inhibitors induce production of renin in the CD that may contribute to decreased renal blood flow. In turn, CD responds with increased VEGF production, resulting in disproportional vessel growth, further worsening the local hypoxia and striped fibrosis surrounding the CDs. Aliskiren, a direct renin inhibitor blocks these effects and improves CNI-induced nephropathy by decreasing renin production in the CDs. Our data suggest that Aliskiren may be used for the prevention of CNI nephrotoxicity.
