Inspiratory Muscle Training in Amateur Athletes

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.

Treatment and study plan

Exercise

Procedure

The training programme will consist of 5 weekly sessions of aerobic work, strength and mobility, plus specific training of the inspiratory muscles, 3 times a week, at a load between 50 and 80% of the maximum inspiratory pressure of each participant, after re-education of their diaphragmatic ventilation.

Primary outcomes

  1. Expiratory forced volume in first second

    Time frame: Before starting the intervention and after its completion (12 weeks)

    FEV1, in liters/second, assessed by spirometry

Secondary outcomes

  1. Hearth rate variability

    Time frame: From the beginning to the end of the programme, recorded on a daily basis.

    In miliseconds, assessed by hearth rate monitor

  2. Hearth rate

    Time frame: 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

  3. Respiratory rate

    Time frame: 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.

  4. Running performance

    Time frame: 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.

  5. Maximal inspiratory pressure

    Time frame: Before starting the intervention and after its completion (12 weeks)

    MIP, in cmH2O, assessed by inspiratory manouever

  6. Maximal consumption of oxygen

    Time frame: Before starting the intervention and after its completion (12 weeks)

    VO2 max, in ml/kg/min, estimated by heart rate monitor in training efforts.
