Summary

The aim of the project will be to assess the functional condition of the respiratory tract and inflammation resulting from obesity, as well as the possibility of using inspiratory muscle training as a factor reducing the occurrence of dysfunction in the respiratory system.

Conditions

• Obesity & Overweight
• Inflammation
• Ventilation Disorders

Interventions

Type	Name	Description
DEVICE	inspiratory muscle training	The IMT experimental group will undergo training with a load of 30% of PImax, assessed in the first inspiratory muscle strength test. Training will be conducted twice a day, with 30 breaths in each training session. From the second week onwards, the training load will be increased by 10% each week. The maximum load will be 60% of PImax. The intervention will last 6 weeks and will be performed daily.
DEVICE	placebo-IMT	The control group will perform simulated inspiratory muscle training with a constant load of 15% PImax. Training will take place 7 times a week, 60 breaths once a day. The intervention will last 6 weeks and will be performed daily.
