First posted: 2017-12-27
Enrollment: 22
Sex: MALE
Minimum age (years): 18
Maximum age (years): 22
Standard ages: ADULT
Accepts healthy volunteers: yes
Allocation: RANDOMIZED
Intervention model: PARALLEL
Intervention model description: Participants will be randomized into two groups: experimental (G-IMT) and sham (Gn-IMT). The two groups will perform a protocol of 8 weeks of training (6 days / week) with the PowerBreath
Primary purpose: TREATMENT

Brief summary: The training of the respiratory muscles seems to be fundamental in people who require a high physical demand. There is abundant scientific evidence that relates the respiratory variables and the limitation to exercise. The published studies are athletics and cycling, however it is scarce in football. Objective. To assess the effects of inspiratory muscle training on lung function and sports performance in soccer players.

Detailed description: Objective. To assess the effects of inspiratory muscle training (IMT) on lung function, inspiratory muscle strength and athletic performance in soccer players.

Method. Participants will be randomized into two groups: experimental and sham . The two groups will perform a protocol of 8 weeks of training (6 days / week) with the PowerBreathe device. The EG will use progressive resistance loads up to 80% of the MIP, while the SG will use the device with a minimum load (20% PImax) during the 8 weeks. All participants will have the following tests before and after the intervention and 3 months after the end of the program: spirometry (FVC, FEV1), PImax, biophotogrammetry, and fit 30/15 test. For the statistical analysis, a 2-factor variance analysis will be performed for repeated measures and Pearson's correlations. The statistical significance will be set with a value of p \<0.05. The effect size will be calculated using the partial eta-square.
