About this study

In the literature, it has been shown in a limited number of studies that respiratory muscle training in sports such as football, cycling, swimming, and rugby reduces athletes' perceived exertion levels. However, the effects of inspiratory and expiratory muscle training on respiratory muscle strength, pulmonary function, and performance status in adolescent athletes are still unclear. Therefore, this study has been planned.

Who can participate

Healthy volunteers accepted: Yes

Only the study team can determine whether someone qualifies for participation.

Inclusion criteria

  • Athletes aged 12-18 who train at a submaximal level at least 3 days a week

Exclusion criteria

  • Adolescents with any history of chronic lung disease
  • unable to comply with the test and training
  • unwilling to participate in the study

Treatment and study plan

Inspiratory muscle training

Device

Inspiratory muscle training will be performed

expiratory muscle training

Device

Expiratory muscle training will be performed

Primary outcomes

  1. Respiratory muscle strength

    Time frame: First day

    Maximal inspiratory and expiratory muscle strength will be evaluated using mouth pressure device .

Secondary outcomes

  1. Constant load-inspiratory muscle endurance test

    Time frame: First day

    It will be evaluated with inspiratory muscle trainer

  2. FEV1

    Time frame: First day

    ulmonary function tests will be performed using a spirometry according to the American Thoracic Society and European Respratory Society criteria. FEV1 will be evaluated. The percentage of predicted value <70% will be expressed as abnormal

  3. FVC

    Time frame: First day

    ulmonary function tests will be performed using a spirometry according to the American Thoracic Society and European Respratory Society criteria. FEV1 will be evaluated. The percentage of predicted value <70% will be expressed as abnormal

  4. FEV1/FVC

    Time frame: First day

    Pulmonary function tests will be performed using a spirometry according to the American Thoracic Society and European Respratory Society criteria. FEV1/FVC will be evaluated.

  5. PEF

    Time frame: First day

    Pulmonary function tests will be performed using a spirometry according to the American Thoracic Society and European Respratory Society criteria. PEF will be evaluated. The percentage of predicted value <70% will be expressed as abnormal

  6. FEF2575

    Time frame: First day

    Pulmonary function tests will be performed using a spirometry according to the American Thoracic Society and European Respratory Society criteria. FEF2575 will be evaluated. The percentage of predicted value <50% will be expressed as abnormal

  7. Athletic performance

    Time frame: second day

    Performance will be evaluated with shuttle run test

  8. Fat free mass Body compositions

    Time frame: second day

    Fat free mass (kg) will be evaluated with bioelectrical impedance analyzer

  9. Fat mass Body compositions

    Time frame: second day

    Fat mass (kg) will be evaluated with bioelectrical impedance analyzer

  10. Fat percentage Body compositions

    Time frame: second day

    Fat percentage (%) will be evaluated with bioelectrical impedance analyzer
