RESUMEN
Durante a pandemia de covid-19, os profissionais de saúde que atuaram na linha de frente viveram um cenário desafiador, com constante risco de infecção pelo SARS-CoV-2, uma demanda de trabalho aumentada e muitas incertezas. O objetivo deste estudo foi analisar as repercussões da covid-19 na saúde de fisioterapeutas baianos atuantes na linha de frente no ambiente hospitalar. Fisioterapeutas baianos participaram deste estudo, respondendo questões referentes aos seus dados sociodemográficos, à qualidade do sono e aos sintomas de ansiedade e depressão, através de um formulário eletrônico (Google Forms). Responderam ao formulário 38 fisioterapeutas residentes em Salvador (BA). A metade deles atua em Unidades de Terapia Intensiva (UTI) e, destes, 65% são trabalhadores do setor privado. Além disso, 68% foram infectados pelo SARS-CoV-2 uma ou mais vezes. O constante medo de infectar seus familiares foi declarado por 77,3% deles e, após o expediente, 36% dos profissionais apresentavam exaustão emocional; 34,2%, estresse psicológico; e 26%, cansaço físico. Os fisioterapeutas baianos relataram que durante a pandemia de covid-19 houve grandes desafios no local de trabalho, como o medo de adoecer e de transmitir a doença e, sobretudo, o medo da morte. O cansaço e o estresse psicológico foram constantes na prática profissional, mas, apesar disso, a maioria dos fisioterapeutas sentiu satisfação por ter atuado de forma tão indispensável em um momento delicado e único.
During COVID-19, health services and professionals who worked on the front line experienced a challenging scenario with a constant risk of infection by SARS-CoV-2, an increased demand for work, and many uncertainties. This study analyzed the repercussions of COVID-19 on the health of Bahian physical therapists working on the hospital front line. Bahian physical therapists participated in this study, answering questions related to their sociodemographic data, sleep quality, and symptoms of anxiety and depression by an electronic form (Google Forms). Overall, 38 physiotherapists living in Salvador (Bahia) answered this form. In total, 50% worked in Intensive Care Units (ICUs); 65%, in the private sector, and 68% suffered infection from SARS-CoV-2 one or more times. This study found that 77.3% of participants reported the constant fear of infecting their family members and 36% showed emotional exhaustion after working hours; 34.2%, psychological stress; and 26%, physical fatigue. Bahian physical therapists reported that COVID-19 brought major confrontations in the workplace, such as the fear of getting sick and transmitting the disease and, above all, death. Fatigue and psychological stress remained constant in the professional practice, but, despite this, most physical therapists felt satisfied for having acted in such an indispensable way in a delicate and unique moment.

RESUMEN
The rise of artificial intelligence (AI) applications in healthcare provides new possibilities for personalized health management. AI-based fitness applications are becoming more common, facilitating the opportunity for individualised exercise prescription. However, the use of AI carries the risk of inadequate expert supervision, and the efficacy and validity of such applications have not been thoroughly investigated, particularly in the context of diverse health conditions. The aim of the study was to critically assess the efficacy of exercise prescriptions generated by OpenAI's Generative Pre-Trained Transformer 4 (GPT-4) model for five example patient profiles with diverse health conditions and fitness goals. Our focus was to assess the model's ability to generate exercise prescriptions based on a singular, initial interaction, akin to a typical user experience. The evaluation was conducted by leading experts in the field of exercise prescription. Five distinct scenarios were formulated, each representing a hypothetical individual with a specific health condition and fitness objective. Upon receiving details of each individual, the GPT-4 model was tasked with generating a 30-day exercise program. These AI-derived exercise programs were subsequently subjected to a thorough evaluation by experts in exercise prescription. The evaluation encompassed adherence to established principles of frequency, intensity, time, and exercise type; integration of perceived exertion levels; consideration for medication intake and the respective medical condition; and the extent of program individualization tailored to each hypothetical profile. The AI model could create general safety-conscious exercise programs for various scenarios. However, the AI-generated exercise prescriptions lacked precision in addressing individual health conditions and goals, often prioritizing excessive safety over the effectiveness of training. The AI-based approach aimed to ensure patient improvement through gradual increases in training load and intensity, but the model's potential to fine-tune its recommendations through ongoing interaction was not fully satisfying. AI technologies, in their current state, can serve as supplemental tools in exercise prescription, particularly in enhancing accessibility for individuals unable to access, often costly, professional advice. However, AI technologies are not yet recommended as a substitute for personalized, progressive, and health condition-specific prescriptions provided by healthcare and fitness professionals. Further research is needed to explore more interactive use of AI models and integration of real-time physiological feedback.
RESUMEN
A pandemia de covid-19 transformou o cotidiano da população mundial. Com as crianças e os adolescentes não foi diferente, o fechamento de escolas, centros esportivos, praças e locais de lazer propiciaram o isolamento social, afastando-os do convívio social e favorecendo a consolidação desse afastamento. Tais mudanças podem suscitar transtornos e representar prejuízos futuros na idade adulta, haja vista que a necessidade de medidas restritivas ao domicílio gera prejuízos na saúde mental da população, desencadeando ansiedade e sofrimento psicológico. Esta revisão visa analisar os efeitos do isolamento social causado pela covid-19 na inatividade física e na saúde mental de crianças e adolescentes. Trata-se de uma revisão sistemática da literatura baseada nas recomendações PRISMA e registrada no PROSPERO. Foram incluídos ensaios clínicos randomizados e estudos observacionais, publicados entre 2020 e 2021 e que envolveram crianças e adolescentes que estiveram em isolamento social. Após a análise dos estudos incluídos, verificou-se redução na prática de atividade física, aumento no tempo de tela e impactos psicossociais com a incidência de depressão leve e moderada, ansiedade e sintomas depressivos. Tais resultados sugerem a importância da criação de políticas públicas com o objetivo de minimizar os efeitos na ansiedade, na qualidade do sono, no tempo de tela e nos sintomas depressivos causados pelo isolamento social, considerando os aspectos biopsicossociais e com foco na promoção da qualidade de vida de crianças e adolescentes.
The COVID-19 pandemic has transformed the daily lives of the world's population. It was no different with children and adolescents, the closure of schools, sports centers, squares, and leisure facilities led to social isolation, keeping them away from social life and favoring the consolidation of this isolation. Such changes can cause disorders and represent future losses in their adulthood, given that the need for restrictive measures at home generates damage to the mental health of the population, triggering anxiety and psychological distress. This review aims to analyze the effects of social isolation caused by COVID-19 on the physical inactivity and the mental health of children and adolescents. This is a systematic review of the literature based on PRISMA recommendations and registered on PROSPERO. Randomized clinical trials and observational studies, published between 2020 and 2021 and involving children and adolescents who were in social isolation, were included. After analyzing the included studies, there was a reduction in the physical activity practice, an increase in screen time, and psychosocial impacts with the incidence of mild and moderate depression, anxiety, and depressive symptoms. These results suggest the importance of creating public policies aimed at minimizing the effects on anxiety, on sleep quality, on screen time, and on depressive symptoms caused by social isolation, considering biopsychosocial aspects and focusing on promoting the quality of life of children and adolescents.
La pandemia del covid-19 ha transformado la vida cotidiana de la población mundial. Con los niños y adolescentes no fue distinto, el cierre de escuelas, polideportivos, plazas y lugares de ocio llevó al aislamiento social, alejándolos de la vida social y favoreciendo la consolidación del aislamiento. Estos cambios pueden derivar en trastornos y representar pérdidas futuras en su edad adulta, dado que la necesidad de medidas restrictivas en el hogar genera daños en la salud mental de la población, desencadenando ansiedad y malestar psicológico. Esta revisión tiene como objetivo analizar los efectos del aislamiento social provocado por el covid-19 en la inactividad física y en la salud mental de niños y adolescentes. Se trata de una revisión sistemática de la literatura basada en las recomendaciones PRISMA y registro PROSPERO. Se incluyeron ensayos clínicos aleatorizados y estudios observacionales, publicados entre 2020 y 2021, que tuvieron como participantes niños y adolescentes que se encontraban en aislamiento social. Del análisis de los estudios incluidos, se observó una reducción en la práctica de actividad física, un aumento en el tiempo de pantalla e impactos psicosociales con la incidencia de depresión leve y moderada, ansiedad y síntomas depresivos. Estos resultados apuntan a la importancia de crear políticas públicas dirigidas a minimizar los efectos sobre la ansiedad, la calidad del sueño, el tiempo de pantalla y los síntomas depresivos causados por el aislamiento social, teniendo en cuenta los aspectos biopsicosociales y enfocándose en la promoción de la calidad de vida de niños y adolescentes.

BACKGROUND: Whole-body vibration exercises (WBVE), that are generated in systemic vibratory therapy (SVT), may benefit individuals with chronic obstructive pulmonary disease (COPD). This study evaluated acute effects of SVT on the flexibility, on the perception of exertion to perform the anterior trunk flexion (ATF), and on the handgrip strength (HG). METHODS: Thirty-eight individuals, separated into two groups, performed a single session of SVT (five bouts, 25 Hz, 2.5 of amplitude) on a side-alternating vibrating platform (SAVP), in two postures: sitting (Sitting group-SitG, n = 21) or standing (Stand group-StandG, n = 17). In both positions, the feet were on the base of the SAVP. The HG and the AFT were performed before and after the session, and the perception of effort (RPE) was measured during the ATF. RESULTS: The ATF in the SitG (p ≤ 0.05) and in the StandG (p ≤ 0.05) was significantly improved, but in the comparison between both groups, no significant reduction was found (p = 0.14). The RPE was not influenced by the session. A significant increase of the HG in StandG post session (33.49 ± 10.30 kgf) p = 0.03 was found, but not in the SitG (p = 0.12) or between the two groups (p = 0.55). CONCLUSIONS: SVT, in a single acute session, would be capable of promoting some functional benefits for the COPD individuals without altering the perception of exertion to perform the ATF. TRIAL REGISTRATION: 49219115.3.0000.5259, RBR-72dqtm.
RESUMEN
Background: Menopause is a natural phase in a woman's aging process. Menopause leads to the decrease of the estrogen levels, and in consequence the functionality worsening. Physical exercise can improve the functionality of postmenopausal woman. This review aimed to assess the effect of whole-body vibration exercise (WBVE) on the functionality of postmenopausal women. Methods: PRISMA guideline were used. Only English language were considered. Searches were conducted using relevant keywords for papers prior to Sep 16th, 2021, in Embase, Pubmed, The Cochrane Library, PED-ro, SPORTDiscus, Scopus, Web of Science and CINAHL databases. Results: Eight articles were selected to be in this systematic review. The mean score of methodological quality was moderate, the risk of bias was low for two studies, high for four studies, and unclear for two studies. The level of evidence of the studies was II. Improvements on muscle strength, jump, balance and maximum trunk flexion strength in the post menopause woman were reported. Conclusion: This systematic review demonstrated the functionality increase in postmenopausal women through WBVE. WBVE has been recommended as a non-pharmacological option relevant to postmenopausal management, helping to control the decline in bone density and symptoms related to osteoporosis and sarcopenia. However, further studies are needed to reinforce these findings.
RESUMEN
Down-syndrome (DS) the most common genetic disorder worldwide. Whole-body-vibration-exercise (WBVE) has been recommended for individuals with DS. To verify the efficacy of WBVE on sleep disorders, body-composition (BC) and clinical parameters of children with DS. It is a randomized cross-over-trial. Children with DS, 5-12 years, both-genders will be selected. The sleep disorders will be evaluated by the "Infant sleep questionnaire Reimão and Lefevre" and by the "Sleep disturbance scale in children". The BC will be measure by bioimpedance and the skin temperature using infrared-thermography. WBVE will be performed seating in an ancillary-chair or sitting on the base of the vibrating platform, with 2.5 mm, 5Hz. Each session (5 series, 30-seconds on vibration, 1-minute of rest). It is expected improvement responses on sleep, BC and some clinical parameters. It is expected that this WBVE protocol will bring important clinical contributions for children with DS.
RESUMEN
COVID-19 has probably contributed as a risk factor for sleep disturbance. Actigraphy has been used to evaluate sleep complaints in self-isolated populations and frontline doctors during the COVID-19 pandemic. This systematic review aims to summarize the impact of the COVID-19 pandemic on sleep through wrist actigraphy, estimating sleep latency, total sleep time, awakening-after-sleep onset, and sleep efficiency. Searches were conducted of observational studies on the PubMed, Embase, Scopus, Web of Science, and PEDro databases from 1 December 2019 to 31 December 2022. Ninety articles were found, and given the eligibility criteria, fifteen were selected. Six studies were classified by the National Health and Medical Research Council as evidence level IV, two studies as level III-3, and seven studies as level III-2. According to the ACROBAT-NRSI instrument, three studies were classified as having a "serious" risk of bias, two as having "critical" risk, four as having "moderate" risk, and six as having "low" risk. In the selected publications, various populations were evaluated via actigraphy during the COVID-19 pandemic, with reports of "poor" sleep quality. Actigraphy may be a relevant tool to assess individual day-night rhythms and provide recommendations under enduring pandemic conditions. Moreover, as actigraphy presents objective data for sleep evaluations, it is suggested that this method be used in similar pandemics and that actigraphy be included as part of the sleep hygiene strategy.
RESUMEN
BACKGROUND: The health and developmental issues of people with Down syndrome (DS) are complex and are associated with many medical, psychological, and social problems from childhood through into adulthood. DS children have an increased risk of multiorgan comorbidities, including congenital heart disease. Atrioventricular septal defect (AVSD) is a congenital heart malformation that often occurs in DS people. AIM: Physical activity and exercise are recommended for patients with cardiovascular disease and are considered to be the gold standard of cardiac rehabilitation. Whole-body vibration exercise (WBVE) is considered a form of exercises. The aim of this case report is to show the effects of WBVE on sleep disturbances, body temperature, body composition, tone, and clinical parameters in a child with DS with corrected total AVSD. The subject is a 10-year-old girl, with free-type DS, who underwent surgery to correct a total AVSD at 6 months. She underwent periodic cardiological monitoring and was released to perform any type of physical exercise, including WBVE. WBVE improved sleep quality and body composition. CONCLUSION: WBVE leads to physiological effects that benefit the DS child.
RESUMEN
BACKGROUND: Inflammation is considered to be a vital defense mechanism for health, acting as a protective response of the immune system through a satisfactory inflammatory biomarker response (IBR). IBR, as well as being beneficial to the organism, can be also responsible for a variety of chronic inflammatory diseases. Whole-body vibration (WBV) exercise is a type of physical exercise that can act on inflammation responses due its capacity for stimulating the sensory components that promote systemic responses. The objective of this study was to investigate the effects of WBV on IBR in different clinical status. METHODS: This is a systematic review that includes randomized controlled trials (RCTs) on the effects of WBV exercise on IBR. The methodological quality, risk of bias, and level of evidence were rated. RESULTS: Four RCTs met the selection criteria. The studies showed benefits associated with IBR (e.g., cytokines, adipokines, and C-reactive protein) in various clinical conditions, including healthy populations and some chronic diseases (such as obesity, aging disorders, and knee osteoarthritis), using several WBV protocols. CONCLUSIONS: WBV might be useful in the management of inflammatory conditions.

Objective: Disrupted sleep and training behaviors in athletes have been reported during the COVID-19 pandemic. We aimed at investigating the combined effects of Ramadan observance and COVID-19 related lockdown in Muslim athletes. Methods: From an international sample of athletes (n = 3,911), 1,681 Muslim athletes (from 44 countries; 25.1 ± 8.7 years, 38% females, 41% elite, 51% team sport athletes) answered a retrospective, cross-sectional questionnaire relating to their behavioral habits pre- and during- COVID-19 lockdown, including: (i) Pittsburgh sleep quality index (PSQI); (ii) insomnia severity index (ISI); (iii) bespoke questions about training, napping, and eating behaviors, and (iv) questions related to training and sleep behaviors during-lockdown and Ramadan compared to lockdown outside of Ramadan. The survey was disseminated predominately through social media, opening 8 July and closing 30 September 2020. Results: The lockdown reduced sleep quality and increased insomnia severity (both p < 0.001). Compared to non-Muslim (n = 2,230), Muslim athletes reported higher PSQI and ISI scores during-lockdown (both p < 0.001), but not pre-lockdown (p > 0.05). Muslim athletes reported longer (p < 0.001; d = 0.29) and later (p < 0.001; d = 0.14) daytime naps, and an increase in late-night meals (p < 0.001; d = 0.49) during- compared to pre-lockdown, associated with lower sleep quality (all p < 0.001). Both sleep quality (χ2 = 222.6; p < 0.001) and training volume (χ2 = 342.4; p < 0.001) were lower during-lockdown and Ramadan compared to lockdown outside of Ramadan in the Muslims athletes. Conclusion: Muslim athletes reported lower sleep quality and higher insomnia severity during- compared to pre-lockdown, and this was exacerbated by Ramadan observance. Therefore, further attention to Muslim athletes is warranted when a circadian disrupter (e.g., lockdown) occurs during Ramadan.
RESUMEN
Objective: To investigate the effect of 1) lockdown duration and 2) training intensity on sleep quality and insomnia symptoms in elite athletes. Methods: 1,454 elite athletes (24.1 ± 6.7 years; 42% female; 41% individual sports) from 40 countries answered a retrospective, cross-sectional, web-based questionnaire relating to their behavioral habits pre- and during- COVID-19 lockdown, including: 1) Pittsburgh sleep quality index (PSQI); 2) Insomnia severity index (ISI); bespoke questions about 3) napping; and 4) training behaviors. The association between dependent (PSQI and ISI) and independent variables (sleep, napping and training behaviors) was determined with multiple regression and is reported as semi-partial correlation coefficient squared (in percentage). Results: 15% of the sample spent < 1 month, 27% spent 1-2 months and 58% spent > 2 months in lockdown. 29% self-reported maintaining the same training intensity during-lockdown whilst 71% reduced training intensity. PSQI (4.1 ± 2.4 to 5.8 ± 3.1; mean difference (MD): 1.7; 95% confidence interval of the difference (95% CI): 1.6-1.9) and ISI (5.1 ± 4.7 to 7.7 ± 6.4; MD: 2.6; 95% CI: 2.3-2.9) scores were higher during-compared to pre-lockdown, associated (all p < 0.001) with longer sleep onset latency (PSQI: 28%; ISI: 23%), later bedtime (PSQI: 13%; ISI: 14%) and later preferred time of day to train (PSQI: 9%; ISI: 5%) during-lockdown. Those who reduced training intensity during-lockdown showed higher PSQI (p < 0.001; MD: 1.25; 95% CI: 0.87-1.63) and ISI (p < 0.001; MD: 2.5; 95% CI: 1.72-3.27) scores compared to those who maintained training intensity. Although PSQI score was not affected by the lockdown duration, ISI score was higher in athletes who spent > 2 months confined compared to those who spent < 1 month (p < 0.001; MD: 1.28; 95% CI: 0.26-2.3). Conclusion: Reducing training intensity during the COVID-19-induced lockdown was associated with lower sleep quality and higher insomnia severity in elite athletes. Lockdown duration had further disrupting effects on elite athletes' sleep behavior. These findings could be of relevance in future lockdown or lockdown-like situations (e.g., prolonged illness, injury, and quarantine after international travel).
RESUMEN
Hypnosis presents an auxiliary adjunct in medical, dental, physiotherapeutic, and other clinical fields. This narrative review verified the effect of hypnosis in the control of pain and anxiety in dentistry. It presents the importance and effectiveness of hypnosis to aid dental procedures. It´s use in dentistry allows a wide range of applications such as sedation, analgesia, anesthesia, and hemostasis to facilitate treatment and improve the experience of dental care for dental patients. A discussion about the regulation of hypnosis in dentistry in Brazil, the attributions of dentists qualified in hypnosis, as well as the benefits of application based on evidence of hypnosis in dentistry, and the need for certification by hypnosis practitioners due to the possible risks inherent to the use of hypnosis are presented. Hypnosis is useful in the management of pain and anxiety in dentistry, when the dental practitioner is adequately experienced in this modality and the patients are carefully selected.

OBJECTIVE: In a convenience sample of athletes, we conducted a survey of COVID-19-mediated lockdown (termed 'lockdown' from this point forward) effects on: (i) circadian rhythms; (ii) sleep; (iii) eating; and (iv) training behaviors. METHODS: In total, 3911 athletes [mean age: 25.1 (range 18-61) years, 1764 female (45%), 2427 team-sport (63%) and 1442 elite (37%) athletes] from 49 countries completed a multilingual cross-sectional survey including the Pittsburgh Sleep Quality Index and Insomnia Severity Index questionnaires, alongside bespoke questions about napping, training, and nutrition behaviors. RESULTS: Pittsburgh Sleep Quality Index (4.3 ± 2.4 to 5.8 ± 3.1) and Insomnia Severity Index (4.8 ± 4.7 to 7.2 ± 6.4) scores increased from pre- to during lockdown (p < 0.001). Pittsburgh Sleep Quality Index was predominantly influenced by sleep-onset latency (p < 0.001; + 29.8%), sleep efficiency (p < 0.001; - 21.1%), and total sleep time (p < 0.001; - 20.1%), whilst Insomnia Severity Index was affected by sleep-onset latency (p < 0.001; + 21.4%), bedtime (p < 0.001; + 9.4%), and eating after midnight (p < 0.001; + 9.1%). During lockdown, athletes reported fewer training sessions per week (- 29.1%; d = 0.99). Athletes went to bed (+ 75 min; 5.4%; d = 1.14) and woke up (+ 150 min; 34.5%; d = 1.71) later during lockdown with an increased total sleep time (+ 48 min; 10.6%; d = 0.83). Lockdown-mediated circadian disruption had more deleterious effects on the sleep quality of individual-sport athletes compared with team-sport athletes (p < 0.001; d = 0.41), elite compared with non-elite athletes (p = 0.028; d = 0.44) and older compared with younger (p = 0.008; d = 0.46) athletes. CONCLUSIONS: These lockdown-induced behavioral changes reduced sleep quality and increased insomnia in athletes. Data-driven and evidence-based recommendations to counter these include, but are not limited to: (i) early outdoor training; (ii) regular meal scheduling (whilst avoiding meals prior to bedtime and caffeine in the evening) with appropriate composition; (iii) regular bedtimes and wake-up times; and (iv) avoidance of long and/or late naps.

(1) Background: This study investigated the effects of two 6-week whole-body vibration exercise (WBVE) protocols on body composition in patients with metabolic syndrome (MSy). Thirty-three patients were allocated to either the Fixed Frequency WBVE Group (FFG-WBVE) or the Variable Frequency WBVE Group (VFG-WBVE). (2) Methods: A side-alternating vibration platform was used and the patients remained in the semi-squat position on this platform. In the FFG-WBVE (n = 12; median age = 50.50 years) and (body mass index BMI = 31.95 kg/m2), patients were exposed to 10 s of mechanical vibration at a fixed frequency of 5 Hz, followed by 50 s without vibration. In the VFG-WBVE (n = 10; median age = 57.50 years) and (BMI = 32.50 kg/m2), the patients performed 60 s of mechanical vibration at different frequencies from 5 to 16 Hz). Body composition evaluated through (bioelectrical impedance analysis and anthropometric measurements) were was evaluated before and after the all the interventions in each group. (3) Results: The VFG-WBVE decreased waist circumference, p = 0.01 and segmental fat mass [left arm, p = 0.01; right arm, p = 0.02 and trunk, p = 0.03]. Bone content increased, p = 0.01. No significant changes were observed in the FFG- WBVE. (4) Conclusions: In conclusion, this study demonstrated that 6 weeks of WBVE with a protocol with variable frequency can positively modify the body composition of MSY patients. These findings might contribute to improvements in the metabolic health of these patients.

PURPOSE: Reduction of muscle strength and lean mass, increase in the risk of falls, higher mortality, and morbidity are observed in geriatric syndromes. Physical activity is an effective intervention in reducing signs and symptoms of geriatric syndromes. Whole-body vibration exercise (WBVE) is an intervention with low cost and has been effective. MATERIALS AND METHODS: The aim of this systematic review aimed to determine the effects of WBVE on neuromuscular activation and muscle strength in the elderly. Searches in PubMed, Embase, Science direct, and Scopus databases were conducted. Six studies, that analyzed the use of surface electromyography evaluating effects of WBVE on neuromuscular activation and muscle strength in the elderly, published in English, were included. RESULTS: Six studies were included. One hundred forty-six individuals participated in the studies and 24 were males (16.43%), with an average age of 74.20 ± 7.66 years. Five publications were defined as "fair" methodological in the PEDro scale, the risk of bias was high and the risk of bias for non-randomized studies was moderate/high. In general, increased strength muscle was reported in the studies. CONCLUSION: This systematic review suggests that WBVE might promote desirable neuromuscular responses in healthy elderly. However, it is necessary to perform further studies to reinforce the reported findings.IMPLICATIONS FOR REHABILITATIONThe reduction in lean mass and consequent reduction in muscle strength are present in healthy elderly people and the whole-body vibration exercise can reduce or alleviate these symptoms caused by the geriatric syndrome.Whole-body vibration exercise is a training modality that increases neuromuscular activation and muscle strength.Surface electromyography is a useful tool for the evaluation of the neuromuscular activation of the muscle fibers.

Symptoms of psychological distress and disorder have been widely reported in people under quarantine during the COVID-19 pandemic; in addition to severe disruption of peoples' daily activity and sleep patterns. This study investigates the association between physical-activity levels and sleep patterns in quarantined individuals. An international Google online survey was launched in April 6th, 2020 for 12-weeks. Forty-one research organizations from Europe, North-Africa, Western-Asia, and the Americas promoted the survey through their networks to the general society, which was made available in 14 languages. The survey was presented in a differential format with questions related to responses "before" and "during" the confinement period. Participants responded to the Pittsburgh Sleep Quality Index (PSQI) questionnaire and the short form of the International Physical Activity Questionnaire. 5056 replies (59.4% female), from Europe (46.4%), Western-Asia (25.4%), America (14.8%) and North-Africa (13.3%) were analysed. The COVID-19 home confinement led to impaired sleep quality, as evidenced by the increase in the global PSQI score (4.37 ± 2.71 before home confinement vs. 5.32 ± 3.23 during home confinement) (p < 0.001). The frequency of individuals experiencing a good sleep decreased from 61% (n = 3063) before home confinement to 48% (n = 2405) during home confinement with highly active individuals experienced better sleep quality (p < 0.001) in both conditions. Time spent engaged in all physical-activity and the metabolic equivalent of task in each physical-activity category (i.e., vigorous, moderate, walking) decreased significantly during COVID-19 home confinement (p < 0.001). The number of hours of daily-sitting increased by ~2 hours/days during home confinement (p < 0.001). COVID-19 home confinement resulted in significantly negative alterations in sleep patterns and physical-activity levels. To maintain health during home confinement, physical-activity promotion and sleep hygiene education and support are strongly warranted.
RESUMEN
BACKGROUND: Overweight and obesity are conditions associated with sedentary lifestyle and accumulation of abdominal fat, determining increased mortality, favoring chronic diseases, and increasing cardiovascular risk. Although the evaluation of body composition and fat distribution are highly relevant, the high cost of the gold standard techniques limits their wide utilization. Therefore, the aim of this work was to explore the relationships between simple anthropometric measures and BIA variables using multivariate linear regression models to estimate body composition and fat distribution in adults. METHODS: In this cross-sectional study, sixty-eight adult individuals (20 males and 48 females) were subjected to bioelectrical impedance analysis (BIA), anthropometric measurements (waist circumference (WC), neck circumference (NC), mid-arm circumference (MAC)), allowing the calculation of conicity index (C-index), fat mass/fat-free mass (FM/FFM) ratios, body mass index (BMI) and body shape index (ABSI). Statistical analyzes were performed with the R program. Nonparametric Statistical tests were applied to compare the characteristics of participants of the groups (normal weight, overweight and obese). For qualitative variables, the Fisher's exact test was applied, and for quantitative variables, the paired Wilcoxon signed-rank test. To evaluate the linear association between each pair of variables, the Pearson correlation coefficient was calculated, and Multivariate linear regression models were adjusted using the stepwise variable selection method, with Akaike Information Criterion (p ≤ 0.05). RESULTS: BIA variables with the highest correlations with anthropometric measures were total body water (TBW), body fat percentage (BFP), FM, FFM and FM/FFM. The multiple linear regression analysis showed, in general, that the same variables can be estimated through simple anthropometric measures. CONCLUSIONS: The assessment of fat distribution in the body is desirable for the diagnosis and definition of obesity severity. However, the high cost of the instruments (dual energy X-ray absorptiometry, hydrostatic weighing, air displacement plethysmography, computed tomography, magnetic resonance) to assess it, favors the use of BMI in the clinical practice. Nevertheless, BMI does not represent a real fat distribution and body fat percentage. This highlights the relevance of the findings of the current study, since simple anthropometric variables can be used to estimate important BIA variables that are related to fat distribution and body composition.
RESUMEN
BACKGROUND: Systemic lupus erythematosus (SLE) is a complex rheumatic autoimmune disease characterized by periods of exacerbations that can present damage in organs with important clinical manifestations. OBJECTIVE: The aim of this study was to evaluate the effect of 12-week whole-body vibration exercise (WBVE) on the fatigue, functional ability and quality of life of women with systemic lupus erythematosus (SLE) in chronic glucocorticoids use (CGU). METHODS: Twenty-one women were allocated randomly in the WBVE group or isometry group. The participants of WBVE group were positioned on the vibrating platform with 130° knee flexion and received the intervention twice a week for 12 weeks. The isometry group performed the same position and time, but without the stimulus of mechanical vibration. Fatigue, functional ability and the quality of life were evaluated at weeks 0, 6, and 12. RESULTS: From a sample of seventy-seven individuals, seventeen participants completed the study, 8 in WBVE group and 9 in isometry group. Fatigue reduced in the WBVE group at 6 and 12 weeks of intervention (p = 0.04) and (p = 0.03) respectively. There was a significant improvement in the functional ability evaluated by the Health Assessment Questionnaire in the WBVE group compared to the isometry group (p = 0.03). CONCLUSION: WBVE would be a useful intervention for control of fatigue and improvement of the functional ability of women with SLE in CGU.

BACKGROUND: The COVID-19 lockdown could engender disruption to lifestyle behaviors, thus impairing mental wellbeing in the general population. This study investigated whether sociodemographic variables, changes in physical activity, and sleep quality from pre- to during lockdown were predictors of change in mental wellbeing in quarantined older adults. METHODS: A 12-week international online survey was launched in 14 languages on 6 April 2020. Forty-one research institutions from Europe, Western-Asia, North-Africa, and the Americas, promoted the survey. The survey was presented in a differential format with questions related to responses "pre" and "during" the lockdown period. Participants responded to the Short Warwick-Edinburgh Mental Wellbeing Scale, the Pittsburgh Sleep Quality Index (PSQI) questionnaire, and the short form of the International Physical Activity Questionnaire. RESULTS: Replies from older adults (aged >55 years, n = 517), mainly from Europe (50.1%), Western-Asia (6.8%), America (30%), and North-Africa (9.3%) were analyzed. The COVID-19 lockdown led to significantly decreased mental wellbeing, sleep quality, and total physical activity energy expenditure levels (all p < 0.001). Regression analysis showed that the change in total PSQI score and total physical activity energy expenditure (F(2, 514) = 66.41 p < 0.001) were significant predictors of the decrease in mental wellbeing from pre- to during lockdown (p < 0.001, R2: 0.20). CONCLUSION: COVID-19 lockdown deleteriously affected physical activity and sleep patterns. Furthermore, change in the total PSQI score and total physical activity energy expenditure were significant predictors for the decrease in mental wellbeing.
