Reliability and Validity of a Portable Traction Dynamometer in Knee-Strength Extension Tests: An Isometric Strength Assessment in Recreationally Active Men.

Background: the study determined the validity and reliability of measurements obtained using the portable traction dynamometer (PTD) (E-Lastic, E-Sports Solutions, Brazil) and the reproducibility between evaluators (precision) in the evaluation of the isometric muscle strength of the knee extensors of healthy male adults, compared to measurements obtained with the "gold standard" computerized dynamometer (CD) (Biodex System 3, Nova York, NY, USA).

Methods: we evaluated sixteen recreationally active men (29.50 ± 7.

Inter-individual variations in response to aerobic and resistance training in hypertensive older adults.

Background: Hemodynamic responses to physical training are not homogenous and uniform, and considerable inter-individual variations in the blood pressure of hypertensive individuals are noted in both aerobic and resistance training protocols. In this context, this study aimed to evaluate the effects of resistance and aerobic exercise on the blood pressure responses of hypertensive older adults.

Methods: Groups were randomly divided into resistance training, n = 20; aerobic training, n = 20; control group, n = 21).

Is resistance training alone an antihypertensive therapy? A meta-analysis.

Evidence concerning the prescription of isolated resistance training (RT) to hypertensive individuals is limited. Guidelines are divergent concerning RT inclusion for prehypertensive and hypertensive persons. A meta-analysis investigating data with larger sample sizes provides more robust effect size estimates and allows for inferences on clinical choices concerning the effectiveness of RT alone.

Parkinson Anxiety Scale: A Validation Study for the Brazilian Population.

Objective: The Parkinson Anxiety Scale (PAS) was developed to measure the severity of anxiety symptoms in patients with Parkinson's disease (PD), and it has not yet been adapted and validated in Portuguese. Thus, this study evaluated the reliability and validity of a translated and adapted version of the PAS for the Brazilian population of PD patients.

Methods: The Parkinson Anxiety Scale - Brazilian Version (PAS-BV) was completed by 55 patients with PD.

Resistance training reduces depressive symptoms in elderly people with Parkinson disease: A controlled randomized study.

Background: Depression affects up to 40% of individuals with Parkinson's disease (PD).

Purpose: To assess resistance training effects on the depressive symptoms of elderly PD patients.

Study Design: A randomized control study.

Strength training improves the respiratory muscle strength and quality of life of elderly with Parkinson disease.

Background: The progression of Parkinson disease can lead to respiratory muscle weakness, reduced peak expiratory flow and quality of life (QoL). The aim was to evaluate the effects of strength training on levels of respiratory muscle strength, peak expiratory flow and QoL of elderly with Parkinson disease.

Methods: A total of 28 patients were randomized into one of two groups: the control group (CG) comprised 16 participants, and the strength training group (STG) comprised 12 participants.

Low-volume resistance training improves the functional capacity of older individuals with Parkinson's disease.

Aim: To evaluate the effects of low-volume resistance training on the physical and functional capacity of older patients with Parkinson's disease.

Methods: A total of 54 patients (aged ≥60 years) were randomly divided into two groups: (i) a control group comprising 13 men and 14 women; and (ii) a resistance training group with 14 men and 13 women. The resistance training group, in addition to maintaining their pharmacological treatments, carried out 6 months of resistance training twice a week, whereas the control group maintained their pharmacological treatments.

Elite athletes have longer telomeres than sedentary subjects: A meta-analysis.

The aim of this meta-analysis was to investigate the effects of high levels of physical activity (in elite athletes) and sedentary lifestyle on telomere length. Our meta-analysis was carried out using the following electronic databases: PubMed, Cochrane Library, LILACS, Science Direct and EBSCO. After study selection, nine articles were included in our meta-analysis.

Resistance training alone reduces systolic and diastolic blood pressure in prehypertensive and hypertensive individuals: meta-analysis.

The purpose of this study was to evaluate the effects of resistance training alone on the systolic and diastolic blood pressure in prehypertensive and hypertensive individuals. Our meta-analysis, followed the guidelines of PRISMA. The search for articles was realized by November 2016 using the following electronic databases: BIREME, PubMed, Cochrane Library, LILACS and SciELO and a search strategy that included the combination of titles of medical affairs and terms of free text to the key concepts: 'hypertension' 'hypertensive', 'prehypertensive', 'resistance training', 'strength training', and 'weight-lifting'.

Swimming and cycling do not cause positive effects on bone mineral density: a systematic review.

Osteoporosis is considered a common metabolic bone disease and its prevalence is increasing worldwide. In this context, physical activity has been used as a non-pharmacological tool for prevention and auxiliary treatment of this disease. The aim of this systematic review was to evaluate the effects of cycling and swimming practice on bone mineral density (BMD).

Single- and multiple-set resistance training improves skeletal and respiratory muscle strength in elderly women.

Introduction: Aging involves a progressive reduction of respiratory muscle strength as well as muscle strength.

Purpose: Compare the effects of resistance training volume on the maximum inspiratory pressure (MIP), maximum expiratory pressure (MEP), functional performance, and muscle strength in elderly women.

Methods: Thirty elderly women were randomly assigned to a group performing either single sets (1-SET) or three sets (3-SET) of exercises.

Prevalence of the use of anabolic-androgenic steroids in Brazil: a systematic review.

The use of anabolic-androgenic steroids (AAS) is increasing among practitioners of recreational physical activity. The aim of this research was to evaluate the prevalence of AAS in practitioners of recreational physical activity in Brazil. After systematic review of four databases, 14 articles were included.
