This study will examine the relationship of airways resistance measured by oscillometry with ventilation defects measured by Phase Resolved Functional Lung (PREFUL) MRI in healthy human subjects.

This study will determine if airway resistance to airflow and pressure, measured by Oscillometry, is associated with abnormal findings on methacholine challenge testing and whether these findings are associated with body habitus,

The effects of manipulation therapy on the autonomic nervous system have been examined in the literature and while no sympathetic or parasympathetic changes were found after upper thoracic manipulation, a decrease in sympathetic data was observed after lower thoracic manipulation and an increase in parasympathetic data was observed. On the other hand, a different study found that thoracic manipulation did not cause any changes such as an increase or decrease in the autonomic nervous system. Therefore, although there are uncertainties in the autonomic role of manipulation therapy, its effect on respiration is intriguing when positive studies are considered. In a study aiming to evaluate the effect of thoracic manipulation on respiratory function, segmental manipulation treatment was applied to healthy individuals by detecting the vertebrae in the thoracic region where normal joint movements were lost, and it was determined that the respiratory functions of the manipulation group improved significantly compared to the group that did not receive treatment. In another study conducted on healthy individuals, the subjects were divided into manipulation group, exercise and manipulation group and control groups. At the end of the study, it was determined that there was a significant increase in the respiratory functions of the participants in the manipulation group, while an additional increase was observed in the group combined with exercise, but this was not significant. No change was observed in the control group. When the literature is examined, it is noteworthy that the effects of manipulation treatments on respiration remain unclear, and especially the inadequacy of studies on Olympic-style weightlifters and the ongoing search for increasing athletic performance in this area. This study aims to examine the effects of cervical and thoracic manipulation treatments on respiratory muscle strength, respiratory functions and cervical and thoracic region joint range of motion in weightlifters. The main question it aims to answer is: \- Is cervical and thoracic manipulation therapy applied to Olympic style weightlifters effective on respiration?

Thoracic surgeries are frequent and pulmonary rehabilitation is essential, since one of the problems that these patients present is dyspnea when performing aerobic exercise, which limits improvement and in some cases causes them to abandon physical exercise. Thanks to carrying out a correct effort retraining program, combining respiratory physiotherapy with therapeutic exercise, patients with respiratory pathologies manage to improve lung capacity and ventilatory mechanics, increase muscle strength and aerobic resistance, prevent long- term complications, reduce fatigue and, ultimately, improve your quality of life. Likewise, it is important to find the most appropriate type of muscular work that produces more benefits in the short and medium term to optimize our resources.The objective of the study is to demonstrate the effectiveness of eccentric training in patients who have undergone thoracic surgery, in terms of strength, lung capacity, functionality and quality of health in the short and medium term. For this purpose, a randomized clinical trial has been designed, with a blinded examiner, following the CONSORT guideline for clinical trials and the ethical principles of the Declaration of Helsinki. A total sample of 57 subjects has been estimated. The study is aimed at patients after scheduled thoracic surgery. A program of 12 group sessions spread over 4 weeks will be carried out. Each of them will last 75 minutes and will include strength and respiratory physiotherapy exercises, common to all subjects. Aerobic interval training will depend on the group assigned: treadmill with negative slope (experimental group), treadmill with positive slope (control group 1) or cycle ergometer (control group 2). On the first and last day of treatment, as well as one month after completing the intervention, the following variables will be measured: thickness, cross-sectional area and ultrasound intensity of the rectus femoris; diaphragmatic excursion and thickness; 6 minute walk test; Borg scale; maximum respiratory pressures; sit-to-stand test; grip strength in both hands; spirometric assessment of FEV1 and SF-12 health quality questionnaire. a
