The Control and Prevention of COVID-19 Transmission in Children: A Protocol for Systematic Review and Meta-analysis.

Background: The pandemic following the rapid spread of the new SARS-CoV-2 virus has hit all continents and caused thousands of deaths worldwide. Evidence has been published on epidemiological and clinical characteristics of population groups considered at risk; however, information for the other population groups, especially for the child population, is needed. In this context, this protocol describes a systematic review that will aim to identify the evidence on control and prevention of COVID-19 transmission among children and adolescents, as well as to describe the epidemiological profile and clinical and immunological characteristics of COVID-19 in this population.

Can people self-select an exercise intensity sufficient to enhance muscular strength during weight training?: A systematic review protocol of intervention studies.

Background: Previous studies have reported that self-selection of the training intensity can be an interesting strategy to improve adherence in aerobic exercise programs. However, its effectiveness with weight training has not been systematically reviewed and remains unclear. In this study, we will describe a systematic review protocol that aims to investigate if people are able to self-select an intensity during weight training sufficient to enhance muscular strength.

Efficacy of Exercise on Breast Cancer Outcomes: A Systematic Review and Meta-analysis of Preclinical Data.

The use of preclinical models to investigate antitumor effects of exercise on breast tumor (BT) development and progression are critical. However, published results have not been quantitatively summarized or examined for potential exercise-moderating variables. We conducted this review to summarize and quantify the effect-size of exercise on BT outcomes in preclinical studies.

Physical Training and Upper-Limb Strength of People With Paraplegia: A Systematic Review.

Context: Physical training improves the strength of upper limbs, contributing directly to the performance of activities of daily life, confirming one more time that the strengthened muscle is imperative for a rapid rehabilitation.

Objective: To investigate the scientific implications of the impact of physical training on the strength of the upper limbs of people with paraplegias.

Evidence Acquisition: The search strategy with truncations and Boolean operator was defined as: (spinal cord inju* OR traumatic myelopat* OR paraplegi*) AND (physical exercise OR strength training OR resisted training) AND (upper limb* OR arm OR armrest), for all of the databases.

Self-Determination and Physical Exercise Adherence in the Contexts of Fitness Academies and Personal Training.

This research aimed to analyze the validity of the relations hypothesized by the theory of self-determination in predicting adherence to physical exercise in fitness academy users and subjects following personal training. A total of 588 persons from Pelotas / RS / Brazil (405 gym users and 183 subjects following personal training) completed the Portuguese version of the three questionnaires, i.e.

Exercise and ankylosing spondylitis with New York modified criteria: a systematic review of controlled trials with meta-analysis.

Ankylosing spondylitis is a systemic rheumatic disease that affects the axial skeleton, causing inflammatory back pain, structural and functional changes which decrease quality of life. Several treatments for ankylosing spondylitis have been proposed and among them the use of exercise. The present study aims to synthesize information from the literature and identify the results of controlled clinical trials on exercise in patients with ankylosing spondylitis with the New York modified diagnostic criteria and to assess whether exercise is more effective than physical activity to reduce functional impairment.

Aging and DNA damage in humans: a meta‐analysis study.

Age‐related DNA damage is regarded as one of the possible explanations of aging. Although a generalized idea about the accumulation of DNA damage with age exists, results found in the literature are inconsistent. To better understand the question of age‐related DNA damage in humans and to identify possible moderator variables, a metaanalysis was conducted.

Validation of the Basic Psychological Needs in Exercise Scale in a Portuguese sample.

In line with self-determination theory (SDT: Deci & Ryan, 1985, 2002) the satisfaction of the basic psychological needs for autonomy, competence, and relatedness has been identified as an important predictor of behavior and optimal functioning in various contexts including exercise. The lack of a valid and reliable instrument to assess the extent to which these needs are fulfilled among Portuguese exercise participants limits the evaluation of causal links proposed by SDT in the Portuguese exercise context. The aim of the present study was to translate into Portuguese and validate the Basic Psychological Needs in Exercise Scale (BPNES: Vlachopoulos & Michailidou, 2006).

Influence of aerobic fitness on age-related lymphocyte DNA damage in humans: relationship with mitochondria respiratory chain and hydrogen peroxide production.

The aim of this study was to analyze the influence of aerobic fitness (AF) on age-related lymphocyte DNA damage in humans, giving special attention to the role of the mitochondrial respiratory chain and hydrogen peroxide production. Considering age and AF (as assessed by VO(2)max), 66 males (19-59 years old) were classified as high fitness (HF) or low fitness (LF) and distributed into one of the following groups: young adults (19-29 years old), adults (30-39 years old), and middle-aged adults (over 40 years old). Peripheral lymphocytes obtained at rest were used to assess DNA damage (strand breaks and formamidopyrimidine DNA glycosylase (FPG) sites through the comet assay), activity of mitochondrial complexes I and II (polarographically measured), and the hydrogen peroxide production rate (assayed by fluorescence).
