The one session of deep tissue massage will be performed. The patient's positions will be changed depending on the specificity of used techniques. The following techniques will be used: • Shifting the rectus abdominis m., • Stretching of the fascia within the costal arches, • trigger points compression (30-60 s). • Stretching of the chest fascia, superficially with forearm or fingertips on intercostal muscles, • "filleting" the pectoral muscles, • "hook and stretch" with the proximal phalanges of the fingers 2-4 and the forearm • "filleting" between the pectoral muscles and the deltoids, • Releasing the lateral edge of the scapula using the fingers and stretching the tissues, Releasing the medial edge of the scapula using the fingers and the weight of the patient, • "hook and stretch" of the trapezius muscle, • Subsequently, the patient will take a prone position. • Stretching of the levator scapulae and supraspinatus muscles using the fist, forearm and elbow will be performed.

The one session of classic massage will be performed. The massage will be performed with moderate force. The entire procedure will take about 15-20 min. The sequence of standard classic massage techniques will be used in standard way and patterns.

Administered as a soft tissue mobilization performed by the therapist with fingertips, knuckles, elbows and/or fists on the tissues that manifest symptoms of fascial restrictions. The techniques were performed with individually adjusted force until the change (eg. increased mobility) in the tissue being treated was stated by the therapist.

The vital capacity of the lungs will be assessed with spirometer. The subject stood with legs hip-width apart. For each measurement, disposable cardboard mouthpieces will be used. The examined person holds the device vertically with both hands. At the examiner's command, subject will take in as much air as possible, then tightly biet the mouthpiece with his mouth, and with all of their strength, exhale air into the device for as long as possible. The subject will have only 1 attempt-measured values were recorded with an accuracy of 50 mL.

The chest circumference will be measured with a measuring tape, wrapped horizontally around the chest at the level of the xiphoid process. The subject stand with feet hip-width apart, arms hanging along the body. At the command, the subject will take a maximum breathe in (first measurement) and exhale to the maximum for the next (second measurement). Obtained values will be recorded with an accuracy of 0.5 cm.

Testing blood oxygen saturation will be performed in a sitting position with digital pulseoximeter. The device will be put on the second finger of the left hand each time. The highest value displayed by the pulseoximeter within 30 s will be recorded with an accuracy of 1%.

Dynamic spirometry test will be performed with spirometer to assess the peak expiratory flow (PEF) measured in liters per second [l/s]. The subject will sit with his legs on the floor-hip joint flexed at an angle of 70o-90o and carry out the following command: "Breathe calmly. On my command, breathe in as much as possible, as quickly as possible, as intensively as possible, and while at the top of the inhalation, without waiting, breathe out as hard and as long as possible ". This cycle will be performed at least 3 times obtaining 3 measurements and the mean value will be calculated.
