Brief Summary

In this study, it was aimed to investigate the acute effect of inspiratory muscle training of different intensities on intercostal muscle oxygenation in healthy individuals.

Conditions

Healthy

Keywords

muscle oxygenation; inspiratory muscle training; intercostal muscle

Outcome Measures

Primary Outcomes (2)

• Evaluation of intercostal muscle oxygenation

  Before the inspiratory muscle training sessions, the muscle oxygen saturation (SmO2) of the intercostal muscles in recovery during and after the training session will be measured using a Moxy® monitor (Moxy, Fortiori Design LLC, Minnesota, USA).

  Second, Third and Fourth day

• Evaluation of intercostal muscle total hemoglobin level

  Before the inspiratory muscle training sessions, total hemoglobin level (THb) of the intercostal muscles in recovery during and after the training session will be measured using a Moxy® monitor (Moxy, Fortiori Design LLC, Minnesota, USA).

  Second, Third and Fourth day

Secondary Outcomes (3)

• Evaluation of respiratory muscle strength

  First day

• Evaluation of respiratory muscle endurance

  First day

• Evaluation of physical activity level

  First day

Study Arms (3)

Sham inspiratory muscle training (Maximal inspiratory pressure (MIP) 0%)

EXPERIMENTAL

Individuals participating in the study will be randomly assigned sham inspiratory muscle training sessions maximal inspiratory pressure of 0% under the supervision of a specialist physiotherapist for 15 minutes.

Device: Sham inspiratory muscle training (MIP 0%)

MIP 30% inspiratory muscle training

EXPERIMENTAL

Individuals participating in the study will be randomly assigned inspiratory muscle training sessions maximal inspiratory pressure of 30% under the supervision of a specialist physiotherapist for 15 minutes.

Device: MIP 30% inspiratory muscle training

MIP 70% inspiratory muscle training

EXPERIMENTAL

Individuals participating in the study will be randomly assigned inspiratory muscle training sessions maximal inspiratory pressure of 70% under the supervision of a specialist physiotherapist for 15 minutes.

Other: MIP 70% inspiratory muscle training
