Beyond the common comorbidities related to obesity, such as type 2 diabetes and cardiovascular diseases, impaired lung function is already known, but whether the fat distribution (sub-cutaneous, visceral) affects the lung function and pulmonary immune response are poorly known. Few evidence has shown that visceral fat is associated with insulin resistance, low-grade inflammation, and reduced lung function. In the present study, the body composition and fat distribution were evaluated by multi-frequency octopolar bioimpedance.

The study seeks to understand whether a physically active lifestyle can improve respiratory capacity, the mechanical efficiency of the lungs, and, consequently, the quality of life of these individuals, comparing data between groups of active and sedentary hypertensive older adults.
Methods: This is a cross-sectional study.
Article Synopsis
- Aerobic physical training (APT) has been shown to decrease eosinophilic airway inflammation in asthma, but its specific effects and mechanisms in severe cases are still not fully understood.
- The study involved both in vitro experiments with human cells related to asthma and in vivo experiments with mice to observe the impact of APT on inflammatory markers and cell activity.
- Results indicated that APT reduced various inflammatory cytokines and other immune cell activities, improved lung function, and increased levels of the anti-inflammatory molecule IL-10, indicating a potential therapeutic role in managing severe asthma.
Article Synopsis
- Asthmatic children have higher levels of pro-inflammatory and pro-fibrotic mediators, leading to increased airway resistance and impaired lung function compared to non-asthmatic children.
- A study involving 78 children (39 asthmatic and 39 non-asthmatic) revealed significant differences in immune response and respiratory mechanics, with asthmatic children showing a marked increase in various blood cells and specific inflammatory factors.
- The research suggests that using impulse oscillometry can effectively measure airway resistance in asthmatic children, highlighting its importance in assessing and managing asthma severity.
Several benefits of aerobic training for asthmatic patients have been demonstrated. However, its effects on systemic inflammation and on airway remodeling mediators and lung mechanics are unknown. This prospective study included 21 intermittent and mild asthma patients, and as primary outcomes, the evaluation of pro- and anti-inflammatory and pro- and antifibrotic mediators in exhaled breath condensate (EBC) and blood were performed, beyond the cell counting in blood and in induced sputum.

We investigated the effects of 12 weeks of combined physical exercise (aerobic + resistance training), in non-obese ( = 12), overweight ( = 17), and obese grade I ( = 11) women. Lung function and lung mechanics were evaluated.

Whereas lung function impairment is well reported for older adult population, the effect of MS on functional and immunological responses in the lungs remains unclear. In this cross-sectional study we determined whether MS alters pulmonary function, and immunological responses in older adults with MS.
View Article and Find Full Text PDFEvidence 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.

Materials And Methods: C57Bl/6 mice were distributed into four groups: Control (Co), Exercise (Exe), Bleomycin (Bleo), and Bleomycin+Exercise (Bleo+Exe).
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.
The effect of resistance training on the anxiety symptoms and quality of life in elderly people with Parkinson's disease: a randomized controlled trial.

Objectives: To assess the effects of resistance training on the anxiety symptoms and quality of life in patients with Parkinson's disease.
Methods: Thirty-five elderly patients were randomly divided into two groups: 17 patients in the control group and 18 in the intervention group. All patients maintained standard pharmacological treatment for Parkinson's disease, but the intervention group participated in a 24-week resistance training program.
