Development steps of multimodal exercise interventions for older adults with multimorbidity: A systematic review.

Background and Aims: Multicomponent exercise interventions are recommended for older adults and for those with chronic diseases. While multiple programs have been tested, no one has yet explored how these programs were developed. This review set out to determine what development steps multicomponent exercise intervention studies that include older adults with multimorbidity have taken. Methods: Systematic review and narrative synthesis. Results: One hundred and thirty-eight studies meeting review criteria (Population: adults ≥60 years with multimorbidity; Intervention: exercise interventions with ≥2 components; Comparator: any considered; Outcome: any considered) were retrieved. Most studies (70%) do not report intervention development actions as suggested by available guidance. Notable deviations from recommendations include limited performance of systematic review of previously published evidence, lack of engagement with theory, and few examples of design then refine. Conclusions: Exercise interventions for older adults with multimorbidity do not appear to follow best practice in terms of their developing. Disregard of development recommendations risks contributing to research redundancy and/or avoidable waste, as important steps that make sure the intervention is warranted, suitable for the population in question, and tested using optimal methods and outcome measures are overlooked.

Effects of physical activity on blood lipids and HbA1c in healthy pregnant women: the FitMum randomized controlled trial.

OBJECTIVE: Maternal blood lipid and glucose concentrations during pregnancy affect fetal growth and the risk of pregnancy and delivery complications. We aimed to investigate the effects of physical activity (PA) during pregnancy on maternal blood lipid and hemoglobin A1c (HbA1c) concentrations. We hypothesized that higher PA was associated with improved lipid profile and glycemic control. METHODS: In a secondary analysis of a randomized controlled trial, we included 216 pregnant women before week 15+0 and tested the effects of two different PA interventions throughout pregnancy compared to standard care on maternal blood lipid and HbA1c concentrations. Additionally, we investigated the effect of PA per se measured by an activity tracker. Total cholesterol (TC), high-density lipoprotein cholesterol (HDL-C), low-density lipoprotein cholesterol (LDL-C), triglyceride, and HbA1c concentrations were measured at week ≤15+0, 28+0-6, 34+0-6, and at delivery (week 32+1 to 42+0). Effects of the interventions and PA per se were tested using linear mixed effects models and linear regression analyses, respectively. RESULTS: No effects of the PA interventions were detected on maternal lipids or HbA1c during pregnancy. In PA per se analyses, more minutes per week of moderate-to-vigorous intensity PA were associated with less increase in TC (-1.3E-04, p=0.020) and LDL-C (-8.5E-05, p=0.035) as pregnancy progresses. More active kilocalories were associated with less increase in TC (-5.5E-05, p<0.001), HDL-C (-9.5E-06, p=0.024), and LDL-C (-3.2E-05, p=0.005). CONCLUSION: Whilst there were no effects of offering PA interventions, higher PA was associated with reduced increases in total cholesterol, HDL-C, and LDL-C as pregnancy progressed.

The Relationship Between Physical Activity and Mental Health Among Individuals With Spinal Cord Injury: Protocol for a Scoping Review.

BACKGROUND: Spinal cord injury (SCI) is a devastating condition that often leads to significant impairments in physical function, leading to disability and mental health disorders. Hence, understanding the prevalence of SCI and the relationship between physical activity and mental health in individuals with SCI is crucial for informing rehabilitation strategies and optimizing outcomes. OBJECTIVE: This study aims to comprehensively analyze existing research on the link between physical activity and mental health and identify the level of physical activity and mental health status, the barriers to physical activity, and SCI's impacts on psychological well-being in individuals with SCI. METHODS: An electronic search strategy will be used to identify prevalence studies published since 1993 in health-related databases such as PubMed, MEDLINE, COCHRANE Library, and Wiley Library using the following query: "Spinal Cord Injury" OR "Paraplegia" OR "Tetraplegia" AND "Physical Activity" OR "Exercise" AND "Mental Health" OR "Mental Illness" OR "Mental Disorder." Bibliographies of primary studies and review articles meeting the inclusion criteria will be searched manually to identify further eligible studies. The risk of bias in the included studies will be appraised using the Joanna Briggs Institute checklist for prevalence studies by 2 review authors. Any disagreement will be resolved by reaching a consensus. RESULTS: Funding was received in October 2023, data collection will commence in July 2024, and the results are expected by 2025. We will summarize the selection of the eligible studies using a flowchart. The data from the studies will be extracted and tabulated. This scoping review will be published in a peer-reviewed journal in accordance with PRISMA-ScR (Preferred Reporting Items for Systematic Reviews and Meta-Analyses extension for Scoping Reviews) guidelines. CONCLUSIONS: This scoping review underscores the complex relationship between physical activity and mental health among individuals with SCI, highlighting the level of physical activity and mental health status, barriers to physical activity engagement, and psychological implications. Understanding these dynamics is crucial in devising tailored interventions aimed at enhancing mental well-being. This synthesis of evidence emphasizes the need for personalized strategies to promote physical activity, addressing unique challenges faced by this population to foster improved mental health outcomes and overall quality of life.

Positive Effects of Physical Activity on Insulin Signaling.

Physical activity is integral to metabolic health, particularly in addressing insulin resistance and related disorders such as type 2 diabetes mellitus (T2DM). Studies consistently demonstrate a strong association between physical activity levels and insulin sensitivity. Regular exercise interventions were shown to significantly improve glycemic control, highlighting exercise as a recommended therapeutic strategy for reducing insulin resistance. Physical inactivity is closely linked to islet cell insufficiency, exacerbating insulin resistance through various pathways including ER stress, mitochondrial dysfunction, oxidative stress, and inflammation. Conversely, physical training and exercise preserve and restore islet function, enhancing peripheral insulin sensitivity. Exercise interventions stimulate ß-cell proliferation through increased circulating levels of growth factors, further emphasizing its role in maintaining pancreatic health and glucose metabolism. Furthermore, sedentary lifestyles contribute to elevated oxidative stress levels and ceramide production, impairing insulin signaling and glucose metabolism. Regular exercise induces anti-inflammatory responses, enhances antioxidant defenses, and promotes mitochondrial function, thereby improving insulin sensitivity and metabolic efficiency. Encouraging individuals to adopt active lifestyles and engage in regular exercise is crucial for preventing and managing insulin resistance and related metabolic disorders, ultimately promoting overall health and well-being.

Effectiveness of exercise interventions on muscle mass among older adults with sarcopenic obesity: A scoping review.

A disease known as sarcopenic obesity is characterized by decreased lean body mass in conjunction with excessive amounts of adipose tissue. Skeletal muscle mass, also known as SMM, is responsible for the largest share of fat-free mass in the body and plays an extremely vital role in the maintaining of metabolic health. Physical activity and exercise boosts the physiological health and overall quality of life of senior citizens. The objective of the study is to investigate the effectiveness of varied exercise interventions among the geriatric people with sarcopenic obesity. During the time period (2016-2023), a scoping review was undertaken using PubMed, orthopedic journals, and the Google Scholar database, and six literature evidences relating to the topic were discovered and subsequently analyzed. The study includes six randomized control trial publications that investigated the effectiveness and impact of exercise therapies on sarcopenic obesity. According to the pre and post-test values found in the reviewed articles, we discovered that resistance exercise is more effective than aerobic or combination exercise therapies. In conclusion, according to this scoping analysis, resistance training is more effective than other types of exercise in improving muscle mass in older people with sarcopenic obesity.

Interventions for psychiatric disorders among university students: An umbrella review of systematic reviews and meta-analyses / Intervenciones para los trastornos psiquiátricos entre estudiantes universitarios: una revisión general de revisiones sistemáticas y metanálisis

Background: Mental disorders are considered to be the main reason for the increase of the disease burden. College students seem to be more vulnerable to the adverse effects of stress, which makes them more at risk of suffering from mental disorders. This umbrella review aimed to evaluate the credibility of published evidence regarding the effects of interventions on mental disorders among university students. Methods: To identify systematic reviews and meta-analyses investigating the effects of interventions on mental disorders in the university student population, extensive searches were carried out in databases including PubMed, Embase, and the Cochrane Database, spanning from inception to July 21, 2023. Subsequently, a thorough reanalysis of crucial parameters such as summary effect estimates, 95 % confidence intervals, heterogeneity I2 statistic, 95 % prediction intervals, small-study effects, and excess significance bias was performed for each meta-analysis found. Results: Nineteen articles involving 74 meta-analyses were included. Our grading of the current evidence showed that interventions based on exercise, Cognitive-behavioural Intervention (CBI), mindfulness-based interventions (MBI), and other interventions like mood and anxiety interventions (MAI) were effective whereas exercise intervention had the highest effect size for both depression and anxiety among university students. However, the credibility of the evidence was weak for most studies. Besides, suggestive evidence was observed for the positive effects of CBI on sleep disturbance(SMD: -0.603, 95 % CI: -0.916, -0.290; P-random effects<0.01) and MAI on anxiety (Hedges'g = -0.198, 95 % CI: -0.302, -0.094; P-random effects<0.01). Conclusion: Based on our findings, it appears that exercise interventions, CBI, and MAI have the potential to alleviate symptoms related to mental disorders...(AU)

Conclusion: Based on our findings, it appears that exercise interventions, CBI, and MAI have the potential to alleviate symptoms related to mental disorders. Despite the overall weak credibility of the evidence and the strength of the associations, these interventions offer a promising avenue for further exploration and research in the future. More high-quality randomized controlled trials should be taken into account to verify the effects of these interventions on various mental disorders.

The effect of exercise training and motivational counselling on physical activity behaviour and psychosocial factors in pregnant women: secondary analyses of the FitMum randomised controlled trial investigating prenatal physical activity.

BACKGROUND: A physically active lifestyle is beneficial during pregnancy. However, little is known about physical activity (PA) behaviour and psychosocial factors in women during and after pregnancy. This study examined exercise behavioural regulation, exercise self-efficacy, health-related quality of life, sickness absence and musculoskeletal pain in pregnant women offered either structured supervised exercise training, motivational counselling on PA, or standard prenatal care in the FitMum randomised controlled trial. METHODS: Two hundred and eighteen healthy inactive pregnant women were randomised to structured supervised exercise training (n = 87), motivational counselling on PA (n = 86) or standard prenatal care (n = 45). The women answered the Behavioural Regulation in Exercise Questionnaire-2 (BREQ-2), the Pregnancy Exercise Self-Efficacy Scale (P-ESES-DK) and the Short Form 36 Health Survey Questionnaire (SF-36) at baseline (gestational age (GA) of max 15 weeks), GA 28 and 34 weeks, and one year after delivery. Sickness absence and low back and/or pelvic girdle pain were likewise reported in questionnaires at baseline and GA 28 weeks. RESULTS: Participants offered structured supervised exercise training or motivational counselling on PA had higher autonomous motivation for exercise during pregnancy compared with participants receiving standard prenatal care (e.g., difference in intrinsic regulation at GA 28 weeks, structured supervised exercise training vs. standard prenatal care: mean difference in score 0.39 [0.16; 0.64], p < 0.001). Participants offered structured supervised exercise training also had higher exercise self-efficacy during pregnancy (e.g., GA 28 weeks, structured supervised exercise training vs. standard prenatal care: mean difference in score 6.97 [2.05; 12.02], p = 0.005). All participants reported high exercise self-efficacy at baseline and medium exercise self-efficacy during pregnancy and one year after delivery. No differences were found between groups in health-related quality of life, sickness absence or low back and/or pelvic girdle pain during pregnancy. No group differences were found one year after delivery. CONCLUSION: Structured supervised exercise training and motivational counselling on PA had important effects on autonomous exercise motivation during pregnancy. Exercise self-efficacy was also increased with structured supervised exercise training compared to standard prenatal care. No group differences in health-related quality of life, sickness absence, or pain were found during and after pregnancy. No effects were found one year post-delivery after intervention cessation. TRIAL REGISTRATION: The study was approved by the Danish National Committee on Health Research Ethics (#H-18011067) and the Danish Data Protection Agency (#P-2019-512). The study adheres to the principles of the Helsinki declaration. Written informed consent was obtained at inclusion.

Sex-specific associations between skeletal muscle mass and incident diabetes: A population-based cohort study.

AIMS: To investigate the sex-specific associations between predicted skeletal muscle mass index (pSMI) and incident type 2 diabetes in a retrospective longitudinal cohort of Chinese men and women. MATERIALS AND METHODS: We enrolled Chinese adults without diabetes at baseline from WATCH (West chinA adulT health CoHort), a large health check-up-based database. We calculated pSMI to estimate skeletal muscular mass, and measured blood glucose variables and assessed self-reported history to identify new-onset diabetes. The nonlinear association between pSMI and incident type 2 diabetes was modelled using the penalized spline method. The piecewise association was estimated using segmented linear splines in weighted Cox proportional hazards regression models. RESULTS: Of 47 885 adults (53.2% women) with a median age of 40 years, 1836 developed type 2 diabetes after a 5-year median follow-up. In women, higher pSMI was associated with a lower risk of incident type 2 diabetes (Pnonlinearity = 0.09, hazard ratio [HR] per standard deviation increment in pSMI: 0.79 [95% confidence interval {CI} 0.68, 0.91]). A nonlinear association of pSMI with incident type 2 diabetes was detected in men (Pnonlinearity < 0.001). In men with pSMI lower than 8.1, higher pSMI was associated with a lower risk of incident type 2 diabetes (HR 0.58 [95% CI 0.40, 0.84]), whereas pSMI was not significantly associated with incident diabetes in men with pSMI equal to or greater than 8.1 (HR 1.08 [95% CI 0.93, 1.25]). CONCLUSIONS: In females, a larger muscular mass is associated with a lower risk of type 2 diabetes. For males, this association is significant only among those with diminished muscle mass.

Effect of exercise interventions based on family management or self-management on glycaemic control in patients with type 2 diabetes mellitus: a systematic review and meta-analysis.

BACKGROUND: Most studies about exercise interventions for patients with type 2 diabetes mellitus (T2DM) have been conducted in hospitals or labs, but it is unclear whether study findings from this specific condition can be generalised to real-life T2DM communities. If patients with T2DM can exercise on their own or with family members, it may also reduce the need for patient supervision by medical staff, thereby reducing the burden of medical treatment and improving condition management's cost-effectiveness and practicability. Much of the current research on exercise interventions for T2DM was focused on the type of exercise and less on the mode of management, so we aimed to examine the effect of exercise interventions based on family management or self-management on glycaemic control in patients with T2DM. METHODS: Articles were searched from eight Chinese and English databases. Randomized control trials (RCTs) published in English and Chinese, from inception to October 17, 2022, were included in this review. The methodological quality of the included studies was assessed using the RCT risk of bias assessment tool provided by the Cochrane Collaboration's tool. Meta-analysis was performed using Rev Man 5.4 and Stata 15.0 software. Heterogeneity was investigated using sensitivity analysis and subgroup analyses. Publication bias was tested by funnel plot and Egger's asymmetry tests. RESULTS: A total of 10 studies with a total of 913 subjects were finally included in this review. The Meta-analysis showed that exercise interventions based on family management or self-management were more effective than control groups in reducing HbA1c (Z = 3.90; 95% CI MD = - 0.81; - 1.21 to - 0.40; P < 0.0001), fasting glucose (Z = 4.63; 95% CI MD = - 1.17; - 1.67 to - 0.68; P < 0.00001), 2-h plasma glucose (Z = 5.53; 95% CI MD = - 1.84; - 2.50 to - 1.19; P < 0.00001), and Low-density lipoproteins levels (Z = 3.73; 95% CI MD = - 0.38; - 0.58 to - 0.18; P = 0.0002). CONCLUSIONS: Exercise interventions based on family management or self-management can significantly reduce glycosylated haemoglobin, fasting glucose, 2-h plasma glucose, and Low-density lipoproteins levels in patients with T2DM, which can effectively delay disease progression and reduce the risk of developing complications. In the future, for exercise interventions based on family or self-management, this review recommended that exercise intervention programmes should be formulated according to 30-60 min per session, more than three times per week, for more than six months of aerobic exercise or aerobic combined with resistance exercise.

Effects of exercise interventions on cognitive functions in healthy populations: A systematic review and meta-analysis.

Chronic exercise intervention is a non-pharmacological therapy suggested to improve cognitive function in various populations. However, few meta-analyses have assessed the cognitive benefits associated with all FITT-VP variables (exercise frequency, intensity, bout duration time, type, volume or total intervention length, and progression) in healthy populations by age. Thus, this meta-analysis assessed the effects of each FITT-VP variable on cognitive function in healthy children, adults, and older adults. This study followed PRISMA guidelines. After searching PubMed and the Web of Science, we included 54 randomized controlled trials to examined the effects of FITT-VP variables on five cognitive domains: global cognition, executive function, memory, attention, and information processing. Moderation analyses assessed the effects by age and by each exercise variables. Exercise benefitted overall cognition and all subcognitive domains. Aerobic and resistance exercise showed the greatest benefits on global cognition and executive function respectively, whereas mind-body exercise benefitted memory. Among all populations, older adults showed the greatest benefits of exercise on global cognition, executive function, and memory compared with controls. Additional studies are needed to assess the effects of exercise on attention and information processing. This meta-analysis offers new insights on the relationships between cognition and FITT-VP exercise variables in healthy populations.

Recreational windsurfing-related acute injuries: a narrative review. Part 2: injury prevention and a proposal for a set of potential prevention strategies with a holistic approach.

Objective: The purpose of this review was to identify existing prevention strategies for recreational windsurfing-related acute injuries and provide clinicians with a practical overview of current evidence supporting proposed potential prevention strategies. Methods: A literature search was conducted through March 8, 2023, using relevant keywords with Boolean operators, such as "windsurfing" AND "injury prevention" and "windsurfing" AND "exercise interventions," from the PubMed and Google Scholar databases. Only peer-reviewed English-articles were included. Results: Existing prevention strategies, right-of-way rules, a new proposed set of eight potential primary to tertiary prevention strategies for windsurfing-related acute injuries, and proposed definitions of injury prevention levels equivalent to Haddon's matrix were identified and tabled. Conclusions: The proposed potential prevention strategies may facilitate clinicians in preventing recreational windsurfing-related acute injuries. Injury prevention for recreational windsurfing is under-researched. Future studies should focus on large prospective clinical trials evaluating the efficacy of prevention strategies for recreational windsurfing-related injuries.

Objectif: Le but de cette étude était d'identifier les stratégies de prévention existantes pour les blessures aiguës liées à la pratique récréative de la planche à voile et de fournir aux cliniciens une vue d'ensemble pratique des preuves actuelles soutenant les stratégies de prévention potentielles proposées. Méthodologie: Une recherche documentaire a été effectuée jusqu'au 8 mars 2023, en utilisant des mots clés pertinents avec des opérateurs booléens, tels que "windsurfing" AND "injury prevention" (planche à voile ET prévention des blessures) et "windsurfing" AND "exercise interventions ¼ (planche à voile ET prescriptions d'exercices) à partir des bases de données PubMed et Google Scholar. Seuls les articles en anglais examinés par des pairs ont été retenus. Résultats: Les stratégies de prévention existantes, les règles de droit de passage, un nouvel ensemble proposé de huit stratégies potentielles de prévention primaire à tertiaire pour les blessures aiguës liées à la pratique de la planche à voile, et les définitions proposées des niveaux de prévention des blessures équivalentes à la matrice de Haddon ont été déterminés et présentés. Conclusions: Les stratégies de prévention potentielles proposées peuvent aider les cliniciens à prévenir les blessures aiguës liées à la pratique récréative de la planche à voile. La prévention des blessures liées à la pratique récréative de la planche à voile n'est pas suffisamment étudiée. Les études futures devraient se pencher sur de vastes essais cliniques prospectifs évaluant l'efficacité des stratégies de prévention des blessures liées à la pratique récréative de la planche à voile.

Examining the Interaction between Exercise, Gut Microbiota, and Neurodegeneration: Future Research Directions.

Physical activity has been demonstrated to have a significant impact on gut microbial diversity and function. Emerging research has revealed certain aspects of the complex interactions between the gut, exercise, microbiota, and neurodegenerative diseases, suggesting that changes in gut microbial diversity and metabolic function may have an impact on the onset and progression of neurological conditions. This study aimed to review the current literature from several databases until 1 June 2023 (PubMed/MEDLINE, Web of Science, and Google Scholar) on the interplay between the gut, physical exercise, microbiota, and neurodegeneration. We summarized the roles of exercise and gut microbiota on neurodegeneration and identified the ways in which these are all connected. The gut-brain axis is a complex and multifaceted network that has gained considerable attention in recent years. Research indicates that gut microbiota plays vital roles in metabolic shifts during physiological or pathophysiological conditions in neurodegenerative diseases; therefore, they are closely related to maintaining overall health and well-being. Similarly, exercise has shown positive effects on brain health and cognitive function, which may reduce/delay the onset of severe neurological disorders. Exercise has been associated with various neurochemical changes, including alterations in cortisol levels, increased production of endorphins, endocannabinoids like anandamide, as well as higher levels of serotonin and dopamine. These changes have been linked to mood improvements, enhanced sleep quality, better motor control, and cognitive enhancements resulting from exercise-induced effects. However, further clinical research is necessary to evaluate changes in bacteria taxa along with age- and sex-based differences.

Differential Impact of Exercises on Quality-of-Life Improvement in Breast Cancer Survivors: A Network Meta-Analysis of Randomized Controlled Trials.

This study aimed to assess the effectiveness of various exercise interventions in enhancing the quality of life for breast cancer survivors. To achieve this, randomized controlled trials were identified from major electronic databases, focusing on the relationship between exercise and quality of life in breast cancer survivors. The primary outcome was the impact of exercise on quality of life 12 weeks after the intervention, with a secondary outcome comparing dropout rates between intervention groups and a regular care control group. The study protocol was registered with INPLASY (INPLASY202340007). A network meta-analysis of nine randomized controlled trials involving 725 participants was conducted, examining aerobic and strength training, aerobic activity, yoga, and strength exercise. Results showed that aerobic and strength training was the most effective intervention, significantly improving the quality of life of breast cancer survivors (1.31; 95% confidence interval: 0.49 to 2.12). Aerobic activity had a borderline effect (0.83; 0.03 to 1.63), while no exercise interventions were associated with an increased dropout risk compared to the control group (regular care). The study concluded that concurrent aerobic and strength training can improve breast cancer survivors' quality of life after 12 weeks of intervention without increasing dropout risk compared to regular care.

Mobility limitations and emotional dysfunction in old age: The moderating effects of physical activity and social ties.

BACKGROUND: This study aims to examine the association between mobility limitations and emotional dysfunction among older Ghanaians and evaluate the buffering effect of physical activity (PA) and social ties in this association. METHODS: The analysis included 1201 adults aged ≥50 from the 2016-17 Aging, Health, Psychological Well-being, and Health-seeking Behavior study. The Medical Outcomes Study Short Form-36 (MOS SF-36) assessed mobility limitations and emotional dysfunction. We measured PA using the International Physical Activity Questionnaire Short Form (IPAQ-SF). Hierarchical OLS regressions were performed to evaluate the hypothesized direct and interactive relationships. RESULTS: The mean age of the sample was 66.2 (SD = 11.9), and 63.3% were women. After full adjustment for potential confounders, OLS regressions found that mobility limitations increased the risk of emotional dysfunction (ß = 0.113, p = 0.004). Moreover, social ties (ß = -0.157, p < 0.001) and PA (ß = -0.096, p < 0.001) were independently and negatively associated with emotional dysfunction. We finally found a significant effect modification of the association of mobility limitations with emotional dysfunction by PA (ß = -0.040, p < 0.002) and social ties (ß = -0.013, p = 0.013). CONCLUSIONS: Mobility-enhancing strategies such as engagement in positive behavioral choices, focusing on regular PA, and maintaining resourceful interpersonal social networks can mitigate the impact of mobility limitations on emotional dysfunction in later life.

Exercise Prescription for the Work-Life Population and Beyond.

The background for this paper concerns a high frequency of work-related disorders that may result from physical exposure at work being highly sedentary, repetitive-monotonous, or physically demanding. This may result in levels of physical inactivity or strenuous activity impairing health. The aim is to present an evidence-based exercise prescription for the work-life population and beyond. The exercise program is designed to be feasible for use at the workplace and/or during leisure time and to improve health, workability, productivity, sickness absence, etc. The specific concept of Intelligent Physical Exercise Training, IPET, includes the assessment of several health-related variables, including musculoskeletal disorders, physical capacity, and physical exposure at work and/or daily life activity. An algorithm with cut-points for prescribing specific exercises is provided. Exercise programs in praxis are addressed through descriptions of precise executions of various prescribed exercises and possible alternatives to optimize variation and adherence. Finally, perspectives on the significance of introducing IPET and the ongoing, as well as future lines of development, are discussed.

Exercise-based interventions on sleep quality in patients with fibromyalgia syndrome: An umbrella and mapping review with meta-analysis.

The main aim of this umbrella review was to assess the impact of exercise-based interventions (EBIs) on sleep quality in patients with fibromyalgia syndrome (FMS). We searched systematically in PubMed, PEDro, EMBASE, CINAHL, SPORTDiscus and Google Scholar. Methodological quality was analyzed using AMSTAR and ROBIS scale, and the strength of evidence was established according to GRADE. Nine systematic reviews were included. Meta-analysis (MA) of primary studies (n = 42) were performed with a random-effects model. The MA revealed a moderate statistically significant effect of EBIs (SMD=-0.46 [-0.69 to -0.23]). Subgroup analyses by type of exercise showed significant effect of body-mind exercises (SMD=-0.55 [-0.86 to -0.23]) and combined exercises (SMD=-1.11 [-2.12 to -0.11]) but not for aerobic (SMD=-0.04 [-0.15 to 0.07]) or strength (SMD=-0.52 [-1.14 to 0.1]) exercises in isolation. The results obtained showed that EBIs were effective in improving sleep quality compared to minimal intervention, no intervention or usual care, with a low certainty of evidence. Subgroup analyses showed that mind-body and combined exercises elicited the strongest effect, while aerobic and strength exercise in isolation did not show significant effects.

Effects of prenatal exercise on gestational weight gain, obstetric and neonatal outcomes: FitMum randomized controlled trial.

BACKGROUND: To investigate the effects of two different exercise interventions during pregnancy on gestational weight gain (GWG) and obstetric and neonatal outcomes compared to standard care. Additionally, we aimed to improve standardization of GWG measurements by developing a model to estimate GWG for a standardized pregnancy period of 40 weeks and 0 days accounting for individual differences in gestational age (GA) at delivery. METHODS: In a randomized controlled trial we compared the effects of structured supervised exercise training (EXE) three times per week throughout pregnancy versus motivational counselling on physical activity (MOT) seven times during pregnancy with standard care (CON) on GWG and obstetric and neonatal outcomes. Uniquely, to estimate GWG for a standardized pregnancy period, we developed a novel model to predict GWG based on longitudinally observed body weights during pregnancy and at admission for delivery. Observed weights were fitted to a mixed effects model that was used to predict maternal body weight and estimate GWG at different gestational ages. Obstetric and neonatal outcomes, among them gestational diabetes mellitus (GDM) and birth weight, were obtained after delivery. GWG and the investigated obstetric and neonatal outcomes are secondary outcomes of the randomized controlled trial, which might be underpowered to detect intervention effects on these outcomes. RESULTS: From 2018-2020, 219 healthy, inactive pregnant women with median pre-pregnancy BMI of 24.1 (21.8-28.7) kg/m2 were included at median GA 12.9 (9.4-13.9) weeks and randomized to EXE (n = 87), MOT (n = 87) or CON (n = 45). In total 178 (81%) completed the study. GWG at GA 40 weeks and 0 days did not differ between groups (CON: 14.9 kg [95% CI, 13.6;16.1]; EXE: 15.7 kg [14.7;16.7]; MOT: 15.0 kg [13.6;16.4], p = 0.538), neither did obstetric nor neonatal outcomes. For example, there were no differences between groups in the proportions of participants developing GDM (CON: 6%, EXE: 7%, MOT: 7%, p = 1.000) or in birth weight (CON: 3630 (3024-3899), EXE: 3768 (3410-4069), MOT: 3665 (3266-3880), p = 0.083). CONCLUSIONS: Neither structured supervised exercise training nor motivational counselling on physical activity during pregnancy affected GWG or obstetric and neonatal outcomes compared to standard care. TRIAL REGISTRATION: ClinicalTrials.gov; NCT03679130; 20/09/2018.

Exploring participants' perspectives on adverse events due to resistance training: a qualitative study.

The objective of this study was to explore the experiences and perspectives of individuals with chronic health conditions who had an adverse event (AE) as a result of resistance training (RT). We conducted web conference or telephone-based one-on-one semi-structured interviews with 12 participants with chronic health conditions who had an AE as a result of RT. Interview data were analyzed using the thematic framework method. Six themes were identified: (1) personal experiences with aging influence perceptions of RT; (2) physical and emotional consequences of AEs limit activities and define future RT participation; (3) injury recovery defines the severity of AE; (4) health conditions influence the perceived risks and benefits of participating in RT; (5) RT setting and trained supervision influence exercise behaviors and risk perceptions; and (6) experiencing a previous AE influences future exercise behavior. Despite participant awareness of the value and benefits of RT in both the context of aging and chronic health conditions, there is concern about experiencing exercise-related AEs. The perceived risks of RT influenced the participants' decision to engage or return to RT. Consequently, to promote RT participation, the risks, not just the benefits, should be properly reported in future studies, translated, and disseminated to the public. Novelty: -To increase the quality of published research with respect to AE reporting in RT studies. -Health care providers and people with common health conditions will be able to make evidence-based decisions as to whether the benefits of RT truly outweigh the risks.

Effects of exercise training on metabolic syndrome risk factors in post-menopausal women - A systematic review and meta-analysis of randomised controlled trials.

BACKGROUND & AIMS: Alterations in the hormonal profiles as women transition to the menopause predisposes individuals to the metabolic syndrome (MetS). In post-menopausal women, this can be exacerbated by sedentary behaviour and physical inactivity. Physical activity can convey many health benefits including improvement in MetS risk factors. However, it remains to be elucidated how differing exercise intensities and its mode of delivery can ameliorate MetS risk factors and resultant progression amongst post-menopausal women. The purpose of this systematic review and meta-analysis was to investigate the effects and efficacy of exercise training on MetS risk factors in post-menopausal women. METHODS: Database searches using PubMed, Scopus, Web of Science and the Cochrane Central Register of Controlled Trials were conducted from inception to December 2021 for randomised controlled studies (RCTs) investigating exercise training (>8 weeks) in at least one of the MetS risk factors in post-menopausal women. Utilising the random-effects model, appropriate standardised mean differences (SMD) or mean differences (MD) with 95% confidence interval (CI) for each MetS risk factor were used to calculate the overall effect size between the exercise and control groups. Sub-group analyses were performed for exercise intensity, modality, and duration for each risk factor. Meta-regression was performed for categorical (health status) and continuous (body mass index) covariates. RESULTS: 39 RCTs (40 studies) involving 2132 participants were identified as eligible. Overall, the meta-analysis shows that exercise training significantly improved all MetS risk factors: waist circumference (WC) [MD: -2.61 cm; 95% CI: -3.39 to -1.86 cm; p < 0.001; 21 studies]; triglycerides (TG) [SMD: -0.40 mmol/L; 95% CI: -0.71 to -0.09 mmol/L; p = 0.01; 25 studies]; high-density lipoprotein (HDL) [SMD: 0.84 mmol/L (95% CI: 0.41-1.27 mmol/L; p < 0.001; 26 studies]; fasting glucose (BG) [SMD: -0.38 mmol/L (95% CI: -0.60 to -0.16 mmol/L; p < 0.001; 20 studies]; systolic blood pressure (SBP) [MD: -5.95 mmHg (95% CI: -7.98 to -3.92 mmHg; p < 0.001; 23 studies]; and diastolic blood pressure (DBP) [MD: -4.14 mmHg (95% CI: -6.19 to -2.08 mmHg; p < 0.001; 23 studies]. Furthermore, sub-group analyses identified that moderate intensity and combined exercise training significantly improved MetS risk factors (p < 0.05) except for HDL, with combined exercise being the most effective. Long duration (≥12 weeks) training also significantly improved MetS risk factors except for TG. Meta-regression revealed no moderating effects on any MetS risk variables. CONCLUSION: This study reinforces the importance of regular physical activity as a non-pharmacological tool in the reduction of MetS risk in post-menopausal women, with significant metabolic improvements seen in interventions spanning 8-10 weeks. Moderate intensity and combined training significantly benefitted abdominal obesity, dyslipidaemia, dysglycaemia and hypertension in post-menopausal women. Improvements in at least one MetS risk were also seen with other exercise modalities and intensities.
