Intervention and mediation effects of a community-based singing group on older adults' perceived physical and mental health: the Sing4Health randomized controlled trial.

ObjectiveTo examine short- and long-term effects of a group singing program on older adults' perceived physical and mental health levels, and also investigate subjective well-being (life satisfaction, positive/negative affect and hedonic balance), body balance and serum biomarkers (C-reactive protein and erythrocyte sedimentation rate) as putative mediating mechanisms, controlling for the cognitive status of the participants. : The randomized controlled trial included 149 participants (60 to 95 years), allocated to an immediate intervention group (IG) or a wait-list active control group (WLG). The intervention comprised 34 sessions of group singing during 4-months.

Emotional intelligence and well-being: Associations and sex- and age-effects during adolescence.

Background: Several studies have suggested that trait and ability-based measures of emotional intelligence (EI) contribute to the promotion of well-being in adults. However, this relationship has not been sufficiently explored among adolescents.

Objective: The present study aims to: i) investigate the associations between EI dimensions and well-being indicators (self-esteem, life satisfaction and social anxiety) in adolescents; and ii) analyze the effect of sex and age on dimensions of EI.

Longitudinal effects of biopsychosocial variables on physical activity after menarche.

Background: The aim of the current study is to analyze the longitudinal effects of certain biopsychosocial variables (socioeconomic status, Body Mass Index (BMI), body image and well-being (QL)), measured at three different menarche stages (S1: before menarche, S2: soon after menarche, and S3: one year after S2), on physical activity and inactivity levels in early adolescence.

Methods: The sample comprised 136 Brazilian teenagers (10-13 years old), showing BMI 18.98 kg/m at the initial assessment, who voluntarily participated in the study.

Psychometric properties of the Brazilian version of the lived experience component of the Spiritual Health And Life-Orientation Measure (SHALOM).

This study had the following aims: (i) to translate the Spiritual Health and Life-Orientation Measure (SHALOM) into Brazilian Portuguese and adapt it to ensure the semantic/conceptual equivalence and content validity of the Brazilian version and (ii) to analyse the psychometric properties-reliability, convergent validity, discriminant validity and factorial validity-of the lived experience component, also called the Spiritual Well-Being Questionnaire (SWBQ), in a calibration sample and in a validation sample of Brazilian adults. The calibration sample comprised 436 subjects, 159 men and 277 women, aged between 18 and 79 years (mean age = 32.20 years; SD = 11.

Physical activity levels in Portuguese adolescents: A 10-year trend analysis (2006-2016).

Objectives: Previous studies have indicated that only a small proportion of Portuguese adolescents attain sufficient levels of physical activity for health. However, it is unknown whether the levels of moderate to vigorous physical activity (MVPA) have changed over a considerable time period in this country. Therefore, the aims of the present study were to examine the 10-year trend changes in self-reported MVPA among adolescents and also investigate differences by sex and age.

Relationship of different perceived exertion scales in walking or running with self-selected and imposed intensity.

The aims of this study were to: (1) compare the Heart Rate (HR) and Rating Perceived Exertion (RPE) in training with self-selected and imposed loads, and (2) associate the OMNI-Walk/Run and Borg scales with self-selected and imposed loads, both on a treadmill. Ten trained men (20.3 ± 2.

[Association amongst physical activity, aging and dementia].

The human possibility of becoming old - the so called Nestor Effect -, as an evolutionary adaptation, is beneficial only if there is some preservation of a certain cognitive character. Differing neuropathological conditions, such as neurodegenerative diseases, due to an abnormal aggregation of certain proteins, may induce chronic inflammatory processes. As so, physical activity increases aerobic fitness and the brain's blood flow capacity, contributing to the decrease of the central nervous system's chronic inflammation, promoting neuroplasticity, and neural circuitry's reorganisation.

Preliminary analysis of the psychometric properties of Ryff's scales of psychological well-being in Portuguese adolescents.

This article presents a set of research studies that aim to adapt Carol Ryff's scales of psychological wellbeing (SPWB) and to analyze its psychometric properties in adolescents. The first two studies focused on the reliability and factorial validity of different Portuguese short versions of SPWB, revealing measurement models inadequacies and low internal consistency. In the third study we developed a shortened version (30 items), taking into account the application of psychometric criteria suggested by van Dierendonck (2005).
