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

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?

About this study

To satisfy the objective of the project, participants will perform an incremental test until volitional exhaustion. During this test, respiratory gases will be measured via a gas analyser as well as the cardiac response via an electrocardiogram. The same participants will have their body composition measured by dual X-ray densitometry (DXA).

Who can participate

Healthy volunteers accepted: Yes

Only the study team can determine whether someone qualifies for participation.

Inclusion criteria

  • Be in enough physical fitness to perform the incremental test to volitional exhaustion.

Exclusion criteria

  • Present any health condition preventing to perform the incremental exercise test until volitional exhaustion.

Treatment and study plan

Incremental exercise test until volitional exhaustion

Primary outcomes

  1. Training status

    Time frame: breath-by-breath during the whole test

    Oxygen uptake at ventilatory threshold 1, ventilatory threshold 2 and maximal oxygen uptake

  2. Body composition

    Time frame: 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).

  3. Bone mineral density

    Time frame: 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).
