Brief summary: This study investigates the effect of two different techniques, stretching of the diaphragm and cervical level impulse technique C3-C4, in the possible spirometric changes, vital capacity (CV), maximum expiratory flow (PEF) and maximum expiratory volume (FEV). in relation to the secondary variables (age, physical activity, BMI, sex). the subjects of the study were informed and clarified doubts about it and its subsequent reading and signing of informed consent. The subjects were randomly selected to determine which intervention group they would belong to (G1: intervention group of the diaphragm muscle stretch technique, G2: intervention group of the cervical rotation rotation impulse technique C3- C4, G3: Combined technique G1 and G2, G4: control group.The evaluation technique is spirometry.The intervention protocol is as follows, first the pre-intervention spirometry is performed, then the corresponding technique (according to intervention group), then the post-intervention spirometry, the intervention technique and at 5 minutes, the intervention technique is performed.

Detailed description: The objectives of the study are the following: 1. To evaluate the changes in the values of the simple spirometry after the application of the study techniques: muscle stretching technique of the diaphragm (G1), rotation impulse technique of the cervical level of C3- C4 (G2) and combined technique of both (G3); 2. Determine the influence of these on measurable respiratory parameters by simple spirometry; 3. Compare the spirometric values obtained after applying the study techniques (G1, G2, G3) and the control group (G4: simulation of a previous technique); and 4. Analyze the different variables measured (age, gender, weight, height, sports practice and body mass index) in the effects of the applied treatment.
