Brief summary: Despite the literature evidence that the "balloon-blowing exercise" improves the pulmonary function as a long-term effect, this exercise has not yet been studied or tested experimentally, meaning that there are no specific and measurable results that attest the improvement on thoracoabdominal movement.


Eligibility criteria: The target population consisted of healthy physiotherapy students from School of Health - Polytechnic of Porto, who volunteered to participate in study.

Inclusion criteria:

- In the Experimental Group B were admitted individuals that, through the analysis of the training record sheet, had executed 2⁄3 of the programmed sessions.

Exclusion criteria:

* Individuals that had participated in aerobic physical activities of moderate (i.e., at least 30 minutes on five days per week) or vigorous intensity (i.e., at least 20 minutes on three days per week) for more than one year;
* Chronic nonspecific lumbopelvic pain (i.e., recurrent episodes of lumbopelvic pain for a period exceeding three months);
* Flu symptoms or respiratory infection up to one week before data collection;
* History of recent ribs fracture and pain in the last three months;
* Pulmonary or rib cage previous pathologies;
* Length discrepancy of the lower limbs or other postural asymmetries;
* History of spinal, gynaecological, or abdominal surgery in the previous year;
* Recurrent muscle/joint pain and history of musculoskeletal injury in the last three months;
* Smoking and/or drinking habits.
