A systematic review and meta-analysis investigating the impact of exercise interventions on heart rate variability in hemodialysis patients.

Patients with chronic kidney disease have a high incidence of cardiovascular diseases, and autonomic dysfunction has a determinant role in the relevant declines. Physical exercise influences heart rate variability and cardiac autonomic modulation. Thus, our objective was to systematically review, with a meta-analysis, the correlation between physical exercise interventions and alterations in cardiac autonomic modulation in hemodialysis patients.

Obesity phenotypes are, in part, associated with physical activity in diabetic hemodialysis patients.

Purpose: To investigate the prevalence of obesity phenotypes and their association with physical activity levels among diabetic hemodialysis patients.

Methods: This is a cross-sectional study with 84 diabetic hemodialysis patients (63.5 ± 9.

Effect of continuous progressive resistance training during hemodialysis on body composition, physical function and quality of life in end-stage renal disease patients: a randomized controlled trial.

Objective: This study aimed to investigate the effect of continuous progressive resistance training on body composition, functional capacity and self-reported quality of life in end-stage renal disease patients.

Design: A randomized controlled trial.

Subjects: The study included 52 hemodialysis patients (aged 55.

Factors Associated With Levels of Physical Activity in Chronic Kidney Disease Patients Undergoing Hemodialysis: The Role of Dialysis Versus Nondialysis Day.

Background: Patients on hemodialysis (HD) report lower physical activity (PA) levels. We analyzed factors associated with low levels of PA in patients with chronic kidney disease (CKD) and compared PA on HD day and non-HD.

Methods: 79 patients wore an accelerometer and were classified according to time spent on moderate-to-vigorous PA (MVPA).

Objectively Measured Physical Activity and Healthcare Expenditures Related to Arterial Hypertension and Diabetes Mellitus in Older Adults: SABE Study.

Research using questionnaires has shown that physical activity level (PAL) is associated with healthcare costs. The purpose of this study was to examine the association between objectively measured PAL and healthcare costs among hypertensive and diabetic noninstitutionalized Brazilian older people. The method consisted of a cross-sectional study forming part of the SABE Study, composed of 377 older people interviewed in 2010.

Moderate-to-Vigorous Physical Activity Among Postmenopausal Women: Discrepancies in Accelerometry-Based Cut-Points.

The objective of this study was to compare moderate-to-vigorous physical activity (MVPA), minutes per week (min/wk), and fulfillment of the current recommendation (150 min/wk of MVPA) based on different cut-points in postmenopausal women. The sample was composed of 233 postmenopausal women aged 59.8 ± 6.

Assessment of Physical Activity by Accelerometer and IPAQ-Short Version in Patients with Chronic Kidney Disease Undergoing Hemodialysis.

Aim: To compare the short version of International Physical Activity Questionnaire (IPAQ) and the accelerometer measurement of physical activity (PA) in patients undergoing hemodialysis.

Methods: Sample consisted of 40 patients (19 men) aged 45 ± 16 years. Patients reported their PA using the IPAQ during a face-to-face interview, and wore an Actigraph GT3-X accelerometer for 1 week to obtain minutes per day of light PA, moderate-to-vigorous PA (MVPA) and total PA as well as raw counts per day (vector magnitude).

[Physical activity and body composition in menopausal women].

Purpose: To analyze the relationship between physical activity and body composition in menopausal women.

Methods: The study included 62 menopausal women aged 50 years or more (61.2±7.

[Cardiorespiratory fitness and body fat distribution in women with 50 years or more].

To verify the relationship between cardiorespiratory fitness and body fat in women. Evaluations were performed on 229 women with ages ranging between 50 and 84 years. Anthropometric assessment was performed and waist/hip ratio and conicity index values were obtained.

Proposal of cut points for the indication of abdominal obesity among adolescents.

Background: The absence of critical values for the cardiovascular risk identification among Brazilian adolescents represents an important limitation.

Objectives: To prepare critical values for the waist circumference and to analyze its efficiency in indicating increased values of the arterial pressure.

Methods: Transversal study that evaluated 1,145 adolescents, from 11 to 17 years old (536 of the male sex and 609 of the female), their body weight values, stature, resistance, reactance, tricipital cutaneous fold, waist circumference and arterial pressure (n = 334) were collected.

[Accuracy of different body mass index cutoffs to predict excessive body fat and abdominal obesity in adolescents].

Objective: To analyze the agreement and accuracy of three body mass index cutoffs in the identification of excessive body fat and abdominal obesity in adolescents.

Methods: Cross-sectional analysis was carried out for which 807 adolescents of both sexes (11 to 17 years old) were recruited and their body mass, stature, waist circumference and body fat percentage measured. The ROC evaluated the accuracy of the body mass index cutoffs.
