Brief summary: Determining the effects of an intervention plan on the diaphragm related to the center of gravity and range of motion in the lumbar spine (static and dynamic) in healthy individuals is an area that lacks evidence and proper studies. Has such, the investigators consider this a interesting topic to study, therefore it is intended to improve the knowledge on this area.

Detailed description: All diaphragmatic activity is controlled by metabolic mechanisms and emotional states which may cause restrictions that might be related to disorders in the lower back.

The diaphragm and the lumbar segment of the spine are connected through the diaphgramathic pillars that connect the central tendon and the vertebrae of L2 (left side) and L3/L4 (right side). Consequently, the contraction of the pillars may be related to the fixation of the lumbar spine.

Proper function of the diaphragm is related to better parameters of static balance. It is also possible to conclude that a change in the proper function of the diaphragm is associated with changes in the center of gravity in healthy individuals.

This theme lacks scientific evidence, since no studies were found that focus on the analysis of diaphragmatic treatment only. In this way, the investigators intend to collaborate to increase knowledge in this area, determining the effects of the intervention plan on the diaphragm in relation to the range of motion and center of gravity in the lumbar spine (static and dynamic) in healthy individuals.

Eligibility criteria: Inclusion Criteria:

* Ages between 18 and 30 years old;
* Both genders;

Exclusion Criteria:

* Treatments with manual therapy in the last three months or more than three times in the previous year;
* Lumbar spine pathology (infection, spinal fracture or more severe neurological impairment, such as cauda equina syndrome) and respiratory pathologies;
* Psychiatric illness;
* Recent history of trauma;
* History of cancer;
* Systemic inflammatory conditions;
* Recent history of spinal surgery;
* Abdominal pain at the time of the intervention;
* Body mass index (BMI) equal to or greater than 31kg / m2, due to the difficulty in accessing the diaphragm;
* All of those that acquired a higher knowledge within the area of manual therapy, which may compromise its validation.
