Inspiratory and Expiratory Muscle Training in Adolescent Volleyball Players

Not Applicable

Recruiting

• Conditions: Adolescent Development

• Registration Number: NCT06759779
• Lead Sponsor: Gazi University

Brief Summary

This study will investigate the effects of inspiratory and expiratory muscle training on respiratory muscle strength, pulmonary function, and performance status in adolescent athletes

Detailed Description

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.

Primary Outcome Measures

Name	Time	Method
Respiratory muscle strength	First day	Maximal inspiratory and expiratory muscle strength will be evaluated using mouth pressure device .

Secondary Outcome Measures

Name	Time	Method
Athletic performance	second day	Performance will be evaluated with shuttle run test
PEF	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
Fat free mass Body compositions	second day	Fat free mass (kg) will be evaluated with bioelectrical impedance analyzer
FEF2575	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
Constant load-inspiratory muscle endurance test	First day	It will be evaluated with inspiratory muscle trainer
FEV1	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
FVC	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
FEV1/FVC	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.
Fat mass Body compositions	second day	Fat mass (kg) will be evaluated with bioelectrical impedance analyzer
Fat percentage Body compositions	second day	Fat percentage (%) will be evaluated with bioelectrical impedance analyzer
