Eight weeks of vigorous exercise are enough for a significant reduction in blood pressure

Medical societies recommend increased physical activity to be part of antihypertensive therapies. However, the intensity and duration of the sessions that can induce signiicant reduction on blood pressure (BP) are to be determined.info:eu-repo/semantics/publishedVersio

The Contribution of Exercise in Telemedicine Monitoring in Reducing the Modifiable Factors of Hypertension - A Multidisciplinary Approach.

The aim of this review was to explore the contribution of physical activity and exercise in the control and reduction of modifiable factors of arterial hypertension in telemedicine programs, assuming a multidisciplinary perspective. Searches were carried out following the PRISMA guidelines (Preferred Reporting Items for Systematic Reviews and Meta-analyses), and the research question defined using the PICOS approach (Population, Intervention, Comparator, Outcomes, Study design). The search strategy applied the following terms: blood pressure OR hypertension AND exercise OR physical activity AND telemedicine. The initial search identified 2190 records, but only 19 studies were considered eligible after checking for the inclusion and exclusion criteria. The following training variables were generally included: heart rate and heart rate reserve, respiratory rate, rate of perceived exertion and oxygen consumption, but no resistance training variables were found. The significant improvements on blood pressure parameters of participants diagnosed with hypertension tended to be transient. The exercise prescription was commonly based on general instructions and recommendations for exercise and hypertension. On the other hand, most of the studies including patients in cardiac rehabilitation programs used a personalized training program based on a baseline assessment, particularly following a cardiopulmonary exercise test. The inclusion of exercise professionals in multidisciplinary teams could provide a more person-oriented approach and the long-term maintenance of a healthy lifestyle.info:eu-repo/semantics/publishedVersio

Interpersonal Behavior, Basic Psychological Needs, Motivation, Eating Behavior, and Body Image in Gym/Fitness Exercisers: A Systematic Review

Background: Body image seems to be a determining factor in the behavior and satisfaction of the basic psychological needs of exercise practitioners in gyms and fitness centers, and may influence motivation, interpersonal behavior, and eating behavior. This review aims to examine possible patterns between the variables under study in a gym/fitness context, specifically considering if body image perception has a determinant factor. Methods: Web of Science, PubMed, SCOPUS, and Psycnet were consulted and only data published between 2007 and 2021 were considered in the present review. After an initial search of 1373 records, a total of 6 were considered eligible for a detailed analysis after checking for the inclusion and exclusion criteria. Results: There is a positive relationship between body image dissatisfaction and less self-determined forms of motivation, as well as the adoption of less healthy eating behaviors. Younger participants have higher levels of body image dissatisfaction and unhealthy eating behaviors. Conclusions: Body image dissatisfaction leads to less self-determined forms of motivation for exercise in the context of gyms and fitness centers. On the other hand, a negative perception of body image can also lead to sustained patterns of less regulated forms of exercise and less healthy eating behaviors.info:eu-repo/semantics/publishedVersio

The Relationship Between Anxiety Levels, Sleep, and Physical Activity During COVID-19 Lockdown: An Exploratory Study

Nowadays and worldwide, the attention is focused on coronavirus disease (COVID-19), and its consequences on mental health are yet to be fully understood. It is important to capture differences in anxiety levels among populations, groups, and the gender-related variation. Therefore, the present study had two main purposes: (1) to characterize the levels of state anxiety and trait anxiety by examining gender-related, sleep-related, and physical activity-related variations in a nonrepresentative sample of the Portuguese population during the first weeks of lockdown; and (2) to explore the possible relationship between trait anxiety and state anxiety and the possible role of gender as a moderator. This cross-sectional study comprised 1,332 Portuguese adults (aged 18–55 years old) recruited online during COVID-19 outbreak measures. Participants answered to sociodemographic data and the Portuguese version of the State-Trait Anxiety Inventory (STAI). Gender differences were found in both state anxiety (p = < 0.001; d = 0.385) and trait anxiety (p = < 0.001; d = 0.467) with females presenting higher values. People reporting doing more physical activity than usual during COVID-19 lockdown presented lower levels of state anxiety (p = < 0.001; d = 0.200). People reporting more satisfaction with the quality of sleep presented lower levels of both state anxiety (p = < 0.001; d = 0.701) and trait anxiety (p = < 0.001; d = 0.899). Variation associated with the physical activity level (low, moderate, and high) was significantly different among groups in both state anxiety (p = < 0.001) and trait anxiety (p = < 0.001). When analyzing in more detail separating the levels of physical activity, participants performing moderate and high physical activity showed lower values of state and trait anxiety compared to participants with low physical activity. Participants performing high physical activity also showed lower values of state anxiety compared to participants performing moderate physical activity. Higher levels of trait anxiety were related to higher levels of state anxiety, but this association was not moderated by gender. Interventions aiming to support people psychologically during this outbreak should consider anxiety as well as gender and possible behavioral changes in sleep and physical activity, for example. Health professionals should not only consider the anxiety related to the situation we are living but also address trait anxiety to help overcome COVID-19 psychological consequences.info:eu-repo/semantics/publishedVersio

Infecção por Streptococcus agalactiae em tilápias do Nilo (Oreochromis niloticus)

This review aims to provide greater understanding of estreptococosis in reared tilapia and thereby assist in choosing the best method of prevention and control of this disease. Streptococcus agalactiae is a cosmopolitan pathogen and the main etiologic agent of septicaemia and meningoencephalitis in teleost. Outbreaks caused by this bacteria lead to high rates of morbidity and mortality of fish, resulting in serious economic losses, especially in the cage tilapia culture that is a branch of aquaculture which produces most in Brazil. This paper presents the main estreptococosis characteristics in Nile tilapia and its prevention by using intraperitoneal vaccines. Further studies should be conducted with the intention of clarifying its pathogenesis and improving the prevention and control.Esta revisão tem por objetivo proporcionar maior entendimento sobre a estreptococose na criação de tilápias e com isso auxiliar na escolha do melhor método de profilaxia e controle desta enfermidade. Streptococcus agalactiae é um patógeno cosmopolita e o principal agente etiológico de septicemia e meningoencefalite em teleósteos. Surtos provocados por essa bactéria levam a altas taxas de morbidade e mortalidade de peixes, resultando em sérios prejuízos econômicos, especialmente na tilapicultura que é o ramo da aquicultura que mais produz no Brasil. Este trabalho traz as principais características da estreptococose em tilápias do Nilo e sua prevenção pelo uso de vacinas intraperitoneais. Novos estudos devem ser realizados com intuito de esclarecer ainda mais sua patogênese e aperfeiçoar os métodos profiláticos e de controle
