Background: The impact of cardiorespiratory fitness (CRF) on cognition is thought to be mediated by brain-derived neurotrophic factor. Aerobic exercise can increase CRF through various activities, including sports participation. The relationship between these factors in females has yet to be elucidated.

MetS has high prevalence among women, which is impacted by food intake. MetS is related to high level of inflammation; however, the impacts of whole diets on biochemical and anthropometrical markers and the effects on MetS need to be further elucidated.

However, population-based studies have revealed that the health effect of marriage or divorce is age-dependent and differs between women and men. The study aimed to identify the age and sex-related associations between marital status with PA and TV time.

Methods: Systematic searches were conducted according to the PICOS strategy and the following databases were searched: PubMed, Web of Science, PsycInfo and Scielo. Two independent evaluators performed the initial selection from reading the title and abstract based on the stipulated eligibility criteria.
: The aim of this study was to propose field-based tests to estimate the anaerobic power of wheelchair basketball athletes. : Eleven lower class wheelchair basketball players performed the Wingate test (WT) and two field-based tests (repeated sprints) of 15 (S-15) and 20 (S-20) meters. The WT provides data in Watts (W).

Background: High-intensity training methods are generally recommended to increase muscle mass and strength, with training loads of 60-70% 1RM for novice and 80-100% 1RM for advanced individuals. Blood flow restriction training, despite using lower intensities (30-50% 1RM), can provide similar improvements in muscle mass and strength. However, studies commonly investigate the effects of blood flow restriction training in large muscular groups, whereas there are few studies that investigated those effects in smaller muscle groups, such as the muscles involved in grasping (e.
View Article and Find Full Text PDFBackground: In the adult population, the work environment and physical fitness levels are directly related to the onset of musculoskeletal pain, repetitive strain injuries, and decreased blood circulation. Although low levels of muscle strength and flexibility may lead to a higher prevalence of pain, specific anatomic regions are poorly addressed.
Objective: To investigate the prevalence of musculoskeletal pain and the association between strength or flexibility and pain in university staff.
This study calculated the exposure-response rates of social-ecological correlates of practicing regular (>150 min/week) leisure-time physical activity (PA) in 393,648 adults from the 27 Brazilian state capitals who participated in a national survey between 2006 and 2016. Regular PA encouraging factors were inputted into an exposure-response model. Growth rates for the odds ratio and prevalence of regular PA were calculated for each increase of one encouraging factor.

Objective: To establish the level of physical activity of university administrative employees and investigate its relationship with muscle strength indicators and morphological characteristics.
Methods: The sample comprised 44 university administrative employees.

Objective: to characterize the physical environment and physical activity (PA) in Primary Health Care Units (PHU) in the urban area of Guarapuava-PR, Brazil, 2011-2012.
Methods: this is a descriptive study in which the coordinators of the municipality's 27 PHUs were interviewed about violence, crime and physical space and safety conditions for PAs inside and outside the PHUs; the streets surrounding the area were visited to evaluate environmental factors categorized as favorable or unfavorable to PA deployment and practice.
Results: the most common places for PA were grass areas (n=18) and churches (n=24); three fifths of PHUs presented factors favorable to PA deployment/practice; lack of sidewalks (14 PHUs) or uneven sidewalks (13 PHUs) surrounding the PHUs are conditions that could jeopardize the practice of walking.
The influence of cardiorespiratory fitness (VO2max) on anthropometric variables and PPARG mRNA expression was investigated. Monozygotic twin pairs aged 11-18 years were grouped into discordant (D) and concordant (C) high and low VO2max groups. VO2max was determined by progressive maximal exercise test on treadmill with gas exchange analysis.

One hundred participants (18-77 years), who were habitual exercisers, associated colors with verbal anchors of the Borg RPE scale (RPE-Borg scale) for RPE-color scale development. For RPE-color scale validation, 12 Young (M = 21.

Objective: To investigate the agreement between two international criteria for classification of children and adolescents nutritional status.
Methods: The study included 778 girls and 863 boys aged from six to 13 years old. Body mass and height were measured and used to calculate the body mass index.
Objective: : To investigate the slope influence on the maximal subtalar pronation in submaximal running speeds.
Methods: : Sixteen endurance runners participated of a running economy (RE) test in a treadmill with different slopes (+1%, +5%, +10%, +15%). For each slope a 4-minute run was performed with no rest break for the purpose of measuring the magnitude of kinematic variables by means of a high frequency video camera positioned in a frontal-posterior plane of the individual.
Objective: To determine if glucose and insulin concentrations are regulated by cardiorespiratory fitness (VO2max) regardless of their genetic effects.
Methods: This cross-sectional study enrolled 38 pairs of young monozygotic twins (11 to 18 years-old). All subjects underwent a progressive maximal exercise test on a treadmill to determine the VO2max with gas exchange analysis (MedGraphics VO2000® - Medical Graphics Corp.
Objective: The aim of the study was to compare static muscular strength test performance between hypertensive and normotensive workers, considering the hypothesis that hypertensive individuals have lower strength than normotensive individuals.
Methods: The participants consisted of 354 workers (246 men and 108 women) who underwent height, body mass, waist circumference, systolic and diastolic blood pressure (BP) measurements, as well as right and left handgrip, and scapular and lumbar strength tests. Assessments were performed during three days in all three shifts, with workers from a candy and sweets factory located in Rio Claro, SP, Brazil.
