Body Composition, Cardiovascular Health, Ventilatory Physiology
Conditions
Brief 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?
Detailed description
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).

Design outcomes
Primary
| Measure | Time frame | Description |
|---|---|---|
| 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). |
