Use of Hyperpolarized 129Xe MR Lung Imaging in Adults for Calibration

The goal of this study is to evaluate the usefulness of hyperpolarized (HP) 129Xe (xenon) gas MRI for regional assessment of lung function in a normal population of adults for the purposes of obtaining optimal images through MRI.

Effect of Aerobic and Resistance Exercise on Quarry Workers

The goal of this randomized clinical trial is to compare the effects of aerobic exercise training and resistance exercise training on ventilatory function in quarry workers. It will also evaluate their effects on functional capacity and health-related quality of life (HRQOL). The main questions it aims to answer are: Does aerobic exercise training improve ventilatory function more effectively than resistance exercise training? How do aerobic and resistance exercise training affect functional capacity and health-related quality of life in quarry workers? Researchers will compare aerobic exercise training and resistance exercise training with a control group receiving routine treatment and breathing exercises to determine which intervention is more effective in improving ventilatory function, functional capacity, and health-related quality of life. Participants will: Be randomly assigned to one of three groups: an aerobic exercise training group, a resistance exercise training group, or a control group. Receive the assigned intervention three times per week for eight consecutive weeks. Undergo ventilatory function assessment using spirometry. Complete assessments of functional capacity and health-related quality of life before and after the intervention.

Exercise Impact in Elderly With Multimorbidity: HbA1c and Blood Pressure

The main objective of the study is to compare the effect of two different types of physical exercise modalities on glycated hemoglobin and blood pressure in elderly individuals with multimorbidity. The main characteristic of the proposal is that it is experimental, with two intervention groups with physical exercise that will be randomized in the order of participation of the groups and forwarded to the researchers regarding the evaluations and training periods. In addition, the study will be controlled, as it has a control group that will not perform any intervention with physical exercises during the study period. To allocate the participants in each exercise group and for the control group, the researchers will use the 1:1 method, the user will receive an automatic generator through the random.org website. The main questions raised by the studies will be: Is land-based training more effective than aquatic training for this population in improving the primary outcomes? Is there a difference between training at these intensities and not doing any physical exercise in this population with these primary outcomes? Participants in the 2 intervention groups will: Train 3x per week for 10 weeks at intensities that will progress over the weeks.

Use of Hyperpolarized Xenon Gas for Lung Imaging in Children and Adults

The goal of this study is to evaluate the usefulness of hyperpolarized (HP) 129Xe (xenon) gas MRI for regional assessment of lung function in a normal population of children and adults and in adults and also in children with respiratory compromise due to a variety of diseases.

Effects of Pulmonary Rehabilitation in Salt Chambers on Functional Efficiency, Respiratory Parameters, and Blood Rheology in Elderly With Respiratory Diseases.

The aim of the study is to assess the impact of the rehabilitation and treatment stay at the underground Health Resort of the 'Wieliczka' Salt Mine in Wieliczka on the functional capacity, respiratory parameters, and rheological properties of blood in elderly individuals with respiratory diseases.
