An umbrella systematic review of the effect of physical exercise on mental health of women in menopause.

IMPORTANCE: The menopausal transition has been related to worsening mental health. The literature also points out that being physically active during menopause is associated with a favorable effect on climacteric symptoms, specifically on psychological aspects. OBJECTIVES: The aims of the study are to analyze the effects of physical activity on mental health during menopause through an umbrella review and to evaluate the quality of the included Systematic Reviews and meta-analyses (MAs). EVIDENCE REVIEW: A MeaSurement Tool to Assess Systematic Reviews was used to evaluate the methodological quality of the included studies and the Grading of Recommendations Assessment, Development and Evaluation was applied to assess the level of the evidence of the results. In addition, the effect size of the revised meta-analyses (MAs) was calculated. FINDINGS: A total of 9 systematic reviews/MAs were included, published between 2014 and 2020. In the A MeaSurement Tool to Assess Systematic Reviews methodological quality assessment, 8 studies were classified as "high quality" and 1 as "low quality." In terms of quality of the evidence for each result through the Grading of Recommendations Assessment, Development and Evaluation classification, approximately 75% of the studies were classified as "moderate quality," 22.2% as "high quality," and 22.2% as "low quality," with the greatest bias concerning the high heterogeneity of the included studies. In addition, the studies showed low overlap. Despite the high heterogeneity, we can highlight the importance of the practice of physical activity by women in menopause, to prevent and/or reduce problems related to mental health. CONCLUSIONS AND RELEVANCE: There was a positive effect of the interventions on depression, however, with no difference between durations (short or long). Regarding stress, the interventions applied did not show a positive effect. The studies that investigated depression linked to anxiety presented conflicting results.

Time-course effects of functional fitness sessions performed at different intensities on the metabolic, hormonal, and BDNF responses in trained men.

BACKGROUND: To investigate the time-course effects of a self-regulated training session (performed at an rating perceived exertion of 6/10), all-out session, and a control session on the metabolic, hormonal, and brain derived neurotrophic factor (BDNF) responses in Functional-Fitness (FFT) participants. METHODS: In a randomized, crossover fashion, eight healthy males (age 28.1 ± 5.4 years old; body mass 77.2 ± 4.4 kg; VO2max: 52.6 ± 4.6 mL.(kg.min)-1; 2000 m rowing test 7.35 ± 0.18 min; 1RM back squat 135.6 ± 21.9 kg) performed a FFT session under two different conditions: all-out, or with the intensity controlled to elicit an rating perceived exertion (RPE) of 6 in the Borg 10-point scale (RPE6). A control session (no exercise) was also completed. Metabolic (lactate and creatine kinase), hormonal (testosterone and cortisol), and BDNF responses were assessed pre, post-0 h, 1 h, 2 h and 24 h after the sessions. RESULTS: Creatine kinase concentrations were significantly higher (p ≤ 0.05) after 24 h for both training sessions. Total and free testosterone concentrations were lower post-2 h for all-out when compared to the RPE6 session (p ≤ 0.05). Serum cortisol concentration increased post-0 h (p = 0.011) for RPE6 and post-0 h (p = 0.003) and post-1 h (p = 0.030) for all-out session when comparing to baseline concentrations. BDNF was significantly higher (p = 0.002) post-0 h only for the all-out session when compared to baseline. A positive correlation between blood lactate concentrations and BDNF (r = 0.51; p = 0.01) was found for both effort interventions. CONCLUSIONS: A single FFT session when performed in all-out format acutely increases the concentrations of serum BDNF. However, physiological stress markers show that the all-out session requires a longer recovery period when compared to the RPE6 protocol. These findings can be helpful to coaches and practitioners design FFT session.

Injuries in functional fitness: an updated systematic review.

INTRODUCTION: This study aimed to analyze injuries of functional fitness participants through a systematic review. EVIDENCE ACQUISITION: A systematic search of the literature was conducted in CINAHL, Embase, Pedro, PubMed, Scopus, SportDiscus, and Web of Science, supplemented by searching in the grey literature, from 2017 to November 2020. This systematic review followed the PRISMA Guidelines and was documented in the PROSPERO Registry (CRD42020201259). Two reviewers independently extracted data including methodological (age, sex, time of practice, location, period, time frame, and completion rate) and injury (definition, diagnosis, prevalence, incidence, severity, mechanism, type, location, risk factors, and treatment) variables, as well as assessing study quality and risk of bias. EVIDENCE SYNTHESIS: Twenty-six studies were included (10,967, range: 6-3049, participants). Injury was defined fairly differently across studies. The majority of studies used a retrospective study design and the main variables reported were prevalence, body location, and associated factors of injuries. The mean prevalence of musculoskeletal injuries was 32.8%, ranging from 2.4 to 60.6%, and the injury incidence per 1000 hours ranged from 0.21 to 36. The most affected body location in the studies was the shoulder, followed by lumbar spine, and knee. Muscle, joint, and ligament/tendon injuries were the most frequently reported. The majority of studies were of moderate methodological quality. All studies were considered as high risk of bias. CONCLUSIONS: This review broadened the scope of previous reviews on injuries in functional fitness. There have been few investigations regarding severity, mechanism, and treatment of injuries, so further research is warranted.

Human needs in COVID-19 isolation.

To reduce the spread of COVID-19, the World Health Organization and the majority of governments have recommended that the entire human population should 'stay-at-home'. A significant proportion of the population live alone or are vulnerable to mental health problems yet, in the vast majority of cases, individuals in social isolation have no access to mental healthcare. The only resource is people themselves using self-help, self-medication and self-care. During prolonged COVID-19 isolation, an in-built system of homeostasis can help rebalance activity, thought and feeling. Increased physical activity enables a reset of physical and mental well-being. During periods of lockdown, it is recommended that exercise should be as vigorously promoted as social distancing itself.
