Differences in Ventilatory Function, Body Composition, and Cardiorrespiratory Fitness According to Training Status

Condition(s) studied

Investigational drug(s) / intervention(s)

Exercise: Incremental exercise test until volitional exhaustion

Study summary

The goal of this cross-over study is to evaluate the physiological response to exercise and body composition according to training status in participants with a wide spectrum of fitness states. The main questions it aims to answer are:

* Which are the physiological differences across participants with different training status?
* Which are the body composition differences across participants with different training status?

Eligibility

Primary outcome measure(s)

• Training status — breath-by-breath during the whole test
  Oxygen uptake at ventilatory threshold 1, ventilatory threshold 2 and maximal oxygen uptake
• Body composition — one determination before the test
  Fat mass (kg), fat free mass (kg), fat mass percentage, fat-free mass (FFM) percentage, weight (kg), and height (m). These variables are assesed by dual-energy X-ray absorptiometry (DXA).
• Bone mineral density — one determination before the test
  Total, lumbar spine and femoral neck bone mineral density (g/cm\^2). These variables are assesed by dual-energy X-ray absorptiometry (DXA).
