Complex Network Model Reveals the Impact of Inspiratory Muscle Pre-Activation on Interactions among Physiological Responses and Muscle Oxygenation during Running and Passive Recovery.

Although several studies have focused on the adaptations provided by inspiratory muscle (IM) training on physical demands, the warm-up or pre-activation (PA) of these muscles alone appears to generate positive effects on physiological responses and performance. This study aimed to understand the effects of inspiratory muscle pre-activation (IM) on high-intensity running and passive recovery, as applied to active subjects. In an original and innovative investigation of the impacts of IM on high-intensity running, we proposed the identification of the interactions among physical characteristics, physiological responses and muscle oxygenation in more and less active muscle to a running exercise using a complex network model.

Purpose: The purpose of this review was to identify different types of physical training programs (aerobic, resistance, or combined), with or without counseling/diet modifications, and their impact on physical fitness in individuals who have class II and III obesity.

Data Sources: Medline and Medline In-Process, EMBASE, the Cochrane Central Register of Controlled Trials, the Cochrane Database of Systematic Reviews, Web of Science, LILACS, CINAHL, SPORTDiscus, PEDro, and PubMed were searched up to June 2017.

Acute effects of photobiomodulation therapy applied to respiratory muscles of chronic obstructive pulmonary disease patients: a double-blind, randomized, placebo-controlled crossover trial.

To investigate the effects of photobiomodulation applied to respiratory muscles on lung function, thoracoabdominal mobility, respiratory muscle strength, and functional capacity in COPD patients. This is a randomized double-blind crossover clinical trial. Twelve male COPD patients participated in the study.

Effects of Water-Based Aerobic Interval Training in Patients With COPD: A RANDOMIZED CONTROLLED TRIAL.

Purpose: Chronic obstructive pulmonary disease promotes systemic repercussions, which can be minimized with physical exercise. This study investigated the effects of a water-based aerobic interval training program on the autonomic modulation of heart rate (HR), quality of life (QoL), and functional capacity (FC) of patients with chronic obstructive pulmonary disease.

Methods: Nineteen patients with chronic obstructive pulmonary disease were enrolled in this randomized clinical trial and allocated to either the usual care group (n = 9) or training group (n = 10).

Water exercise in coronary artery disease patients, effects on heart rate variability, and body composition: A randomized controlled trial.

Background And Purpose: It is important to assess the effectiveness and efficiency of water-based training programs in order to prescribe it as an alternative in cardiac rehabilitation for patients who have coronary artery disease (CAD). In these patients, autonomic dysfunction is an important physiological change strongly associated with adverse outcomes, morbidity, and mortality. Given that the beneficial effects of physical training in CAD patients have been traditionally evidenced with programs involving land-based aerobic exercises, this study aims to evaluate the effects of water aerobic exercise training (WAET) on the autonomic modulation of heart rate (HR) and body composition, in the rehabilitation of CAD patients.

Analysis of autonomic modulation of heart rate in patients with Parkinson's disease and elderly individuals submitted to game therapy training.

Aim: Elderly patients and individuals with Parkinson's disease have a reduction in autonomic heart rate modulation, which may influence the survival of these patients, and rehabilitation can minimize this event. We tested the hypothesis that rehabilitation protocol with game console would influence the cardiac autonomic modulation of patients with Parkinson's Disease.

Methods: Eight-seven volunteers were divided into two groups, control (n = 45) and Parkinson's (n = 42), they completed the study 40 volunteers in the control group (CG) and 31 patients in the Parkinson group (PG), and subjected to 24 sessions of game therapy physiotherapy, thrice a week.

Evaluation of maximal inspiratory and sniff nasal inspiratory pressures in pre- and postoperative myocardial revascularization.

Objective: The objective of this study was to evaluate and correlate inspiratory muscle strength using maximal inspiratory pressure (MIP) and sniff nasal inspiratory pressure (Pnsn) in patients with coronary artery disease in pre- and postoperative of myocardial revascularization surgery.

Methods: Thirty-eight men were studied, divided into a control group (CG) comprised of healthy individuals (n=18), age 55.52 ± 7.

Postural drainage and manual lymphatic drainage for lower limb edema in women with morbid obesity after bariatric surgery: a randomized controlled trial.

Objective: The aim of this study was to evaluate the effects of postural drainage (PD) and manual lymphatic drainage (MLD) techniques on edema in the lower limbs of women with morbid obesity submitted to bariatric surgery.

Design: A total of 47 women between 20 and 40 yrs old with a body mass index of 40 kg/m or higher were randomly placed in three groups: control group (n = 15), PD group (PDG, n = 16), and MLD group (n = 16). Lower limb perimetry was carried out in the first and third days of the postoperative period.

Methods: We evaluated 243 healthy individuals (111 males and 132 females), between 20 and 80 years of age, with an FVC and FEV1/FVC ratio > 80% and > 85% of the predicted value, respectively. All of the subjects underwent respiratory muscle strength tests to determine MIP, MEP, and SNIP.

Autonomic modulation of heart rate in paraplegic wheelchair basketball players: Linear and nonlinear analysis.

This study aimed to evaluate the autonomic modulation of heart rate in sedentary paraplegics and paraplegic wheelchair basketball players with thoracic spinal cord injury below T6. Seven paraplegic wheelchair basketball players (active paraplegic group), five paraplegics who were not involved in regular exercise (sedentary paraplegic group) and 10 able-bodied participants (control group) took part in the study. The heart rate variability was evaluated by linear (low frequency and high frequency band in normalised units and low frequency/high frequency ratio) and nonlinear methods (Shannon entropy, corrected conditional entropy, and symbolic analysis).

The influence of motor impairment on autonomic heart rate modulation among children with cerebral palsy.

The study of heart rate variability is an important tool for a noninvasive evaluation of the neurocardiac integrity. The present study aims to evaluate the autonomic heart rate modulation in supine and standing positions in 12 children diagnosed with cerebral palsy and 16 children with typical motor development (control group), as well as to relate the level of motor impairment in children with cerebral palsy, as classified by to the Gross Motor Function Classification System, to the heart rate variability indices. The heart rate variability was analyzed by linear model in the frequency domain, at low and high frequency bands in normalized units and low and high frequency ratio.
