Brief Summary

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.

Outcome Measures

Primary Outcomes (1)

• 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 Outcomes (3)

• Change from baseline muscle recovery after treatment and at month

  Screening visit, within the first seven days after treatment and after one month follow-up visit

• Change from baseline aerobic performance after treatment and at month

  Screening visit, within the first seven days after treatment and after one month follow-up visit

• Change from baseline anaerobic performance after treatment and at month

  Screening visit, within the first seven days after treatment and after one month follow-up visit

Study Arms (2)

Experimental group

EXPERIMENTAL

Each session will last 10 minutes, taking place 5 days a week, over a period of 6 weeks. The intervention will take place at the beginning of each training session. Prior to training, the muscle training technique will be performed against a resistance of 50% of the maximum inspiratory pressure of each athlete

Other: 50% resistance

Control group

ACTIVE COMPARATOR

Each session will last 10 minutes, taking place 5 days a week, over a period of 6 weeks. The intervention will take place at the beginning of each training session. Prior to training, the muscle training technique will be performed against a resistance of 10% of the maximum inspiratory pressure of each athlete

Other: 10% resistance

Interventions

50% resistance OTHER

Prior to training, the muscle training technique will be performed. The objective of applying the intervention using the Powerbreathe® device is to produce an increase in inspiratory force. The technique will be performed with the athlete standing, holding the device with his hand and his lips sealed on the mouthpiece. After a full expiration, you will make a quick and deep inspiration. The principal investigator of the study will ensure that the technique is performed correctly. There will be 2 series of 30 maximum inspirations. These interventions will be faced with a resistance of 50% of the maximum inspiratory pressure of each athlete
