NCT04737824 - Immediate and Long-term Effects of an Adaptation of the "Balloon-blowing Exercise" | Crick

Overview

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.

An adaptation of the "balloon-blowing" exercisePROCEDURE

The participants were positioned in supine, on a semi-rigid surface, with the upper limbs placed above the level of the head, at rest. Their feet were also placed at a resting position on a wall and with their hips and knees at 90o of flexion. The cervical was placed in a neutral position and the pelvis was maintained in a posterior pelvic tilt, both structures corrected by the researcher. The participants were asked to contract the adductors, maintaining a bilateral and symmetric pressure between 10 and 15 mmHg on two sphygmomanometers placed between the knees. Also, an isometric contraction of the hamstrings and gluteus was requested. A Threshold®, with a minimum resistance of 5 cmH2O, and they were instructed to close their lips around the mouthpiece, to avoid air leaks. To start the exercise, it was transmitted to the participants to make a maximum inspiration through the nose, for two seconds. Subsequently, a maximum exhalation throughout the threshold was made for three seconds.
