Soccer requires the activation of aerobic and anaerobic metabolism. The increase of the ventilatory demand stimulates the increase of the neural impulse to the respiratory muscles, increasing the mechanical power of the inspiratory muscles. The main objective of the study is to assess the effectiveness in the improvement of the strength of the inspiratory muscles and the muscular recovery with the Powerbreathe® device in semi-professional soccer players. Randomized double-blind clinical study with follow-up period. 36 semi-professional soccer players from the province of Soria will be randomly distributed to the study groups: experimental (inspiratory muscle training with 50% resistance) and control (10% resistance training). The dependent variables will be: aerobic and anaerobic sports performance (Cooper's 12-Minute Run Test and Repeated Sprint Ability), blood lactate concentration (Lactate Scout®), and lung function using the ergo-respiratory parameters (maximum inspiratory pressure, expiratory pressure maximum, forced vital capacity and forced expiratory volume in 1 second). The sample distribution will be calculated using the Kolmogorov-Smirnov test. The changes after each evaluation will be analyzed with the t-student test and with an ANOVA of repeated measures, the intra and intersubject effect will be observed. The effect size will be calculated using Cohen's formula. It is intended to observe improvement in inspiratory strength levels, decrease in blood lactate concentration and an increase in aerobic and anaerobic sports performance.

Primary | Change from baseline inspiratory force after treatment and at month | An assessment will be made by spirometry of the maximum inspiratory pressure. A portable spirometer will be used (Mir Smart One model, MIR INC, New Berlin, WI, USA). The evaluation will be carried out according to the protocol indicated by the American Thoracic Society. The athlete will be placed in standing position holding the mouthpiece with his hand and with the wise sealed around it. After a full expiration you will proceed to a quick and deep inspiration. The unit of measure of this measuring instrument is cmH2O. A higher score indicates a greater inspiratory force. | Screening visit, within the first seven days after treatment and after one month follow-up visit | |
Secondary | Change from baseline muscle recovery after treatment and at month | It will be done by measuring blood lactate concentration. The measurement protocol used was described by Coyle et al. A puncture will be made in the earlobe for blood measurement, using puncture lancets, while the results will be analyzed with a lactate analyzer, model Lactate Scout 4 (model Scout Lactate, EKF Diagnostics, Germany). The unit of measure is mmol / l. A lower concentration of lactate in the blood indicates a greater capacity for muscle recovery. | Screening visit, within the first seven days after treatment and after one month follow-up visit | |
Secondary | Change from baseline aerobic performance after treatment and at month | It will be done by applying the Cooper's 12-Minute Run test. With this test, the number of laps that the athlete is able to run in a period of 12 minutes, to an area of 300 meters, will be measured. The unit of measure is the number of turns that the player is able to perform, indicating a greater distance, a greater aerobic performance. | Screening visit, within the first seven days after treatment and after one month follow-up visit | |
Secondary | Change from baseline anaerobic performance after treatment and at month | It will be done by applying the Repeated Sprint Ability (RSA) test. With this test, the time it takes for the athlete to make 6 sprints of 40 meters (20 + 20) with 20 seconds of rest between each one will be measured. The unit of measure is temporary (seconds). Performing sprints in less time indicates greater anaerobic performance. | Screening visit, within the first seven days after treatment and after one month follow-up visit |
