NCT05759598

Brief Summary

The study's primary objective is to evaluate the acute and chronic (3 weeks) effects of two respiratory training protocols in obese adolescents (performed during a period of hospitalization for a body weight reduction program), with different characteristics and mechanisms of action, on GH and IGF-I secretion. The definition of the protocols is based on what has been observed by recent studies conducted on healthy people (Wuthrich et al., 2015; Schaer et al., 2018) and on patient populations in which respiratory dysfunction is a primary or secondary component of the pathology (Calcaterra et al., 2014; Pomidori et al., 2009). All planned interventions are safe and are adapted to the obese patient. Project objectives are:

  • assessment of GH-IGF-I responses (baseline), during the first training session of the respiratory muscles conducted in the first days of hospitalization of the patients in the clinic
  • assessment of GH-IGF-I responses (post), during the last training session of the respiratory muscles conducted at the end of the three weeks of each training session

Experimental group (RMT)

EXPERIMENTAL
Other: Rehabilitation protocol + specific respiratory muscle training program

Interventions

Standard integrated metabolic rehabilitation protocol + guided spontaneous breathing exercises

Control group (CTRL)

Standard integrated metabolic rehabilitation protocol + specific respiratory muscle training program according to the protocol recently proposed by Spengler et al. (Wuthrich et al., 2015; Schaer et al., 2018), adapted according to the baseline characteristics of the respiratory function of the subjects
