Inspiratory Muscle Training in Amateur Athletes

Not Applicable

Active, not recruiting

• Conditions: Amateur Athletes
• Interventions: Procedure: Exercise

• Registration Number: NCT06611969
• Lead Sponsor: University of Valencia

Brief Summary

The main objective of the study is to study the changes in FEV1 with the introduction of the specific inspiratory muscle training programme in the training programme of the popular athletes included. In addition, the secondary aims are to observe the differences in the respiratory capacities of the patients, in the vital signs, VO2 max, respiratory frequency and cardiac variability, as well as to assess the running performance of the participants.

Participants will be assigned to one of 2 study groups: IMT group (n=20) or not-IMT group (n=20) The IMT group will perform inspiratory muscle training in conjunction with the conventional marathon training plan. The not-IMT group will follow only the conventional marathon training plan. The study will be conducted over a 12 week period.

Arm && Interventions

Group	Intervention	Description
Inspiratory muscle training (IMT) plus conventional training group	Exercise	IMT group will perform inspiratory muscle training in conjunction with the conventional marathon training plan
Conventional training group (not-IMT) group	Exercise	The not-IMT group will follow only the conventional marathon training plan

Primary Outcome Measures

Name	Time	Method
Expiratory forced volume in first second	Before starting the intervention and after its completion (12 weeks)	FEV1, in liters/second, assessed by spirometry

Secondary Outcome Measures

Name	Time	Method
Hearth rate variability	From the beginning to the end of the programme, recorded on a daily basis.	In miliseconds, assessed by hearth rate monitor
Hearth rate	From the beginning to the end of the programme, recorded on a daily basis.	Maximal and specifically in rest, measured in beats per minute, assessed by heart rate monitor
Respiratory rate	From the beginning to the end of the programme, recorded on a daily basis.	Measured in respirations per minute, estimated by the hearth rate monitor.
Running performance	From the beginning to the end of the programme, recorded on a daily basis.	Measured by running pace (time per kilometre) and perceived exertion (modified Borg scale 0-10), recorded individually in a written register.
Maximal inspiratory pressure	Before starting the intervention and after its completion (12 weeks)	MIP, in cmH2O, assessed by inspiratory manouever
Maximal consumption of oxygen	Before starting the intervention and after its completion (12 weeks)	VO2 max, in ml/kg/min, estimated by heart rate monitor in training efforts.
