Brief summary
Several studies have shown relationship between exercise intensity and improvement cardiometabolic health. It has been suggested that high intensity interval training and also moderate training generate positive effects on metabolic risk factors. For these reasons, it is necessary to clarify which type of training, is more effective to improve cardiometabolic health in latinamerican population.
Interventions
BEHAVIORALHigh Intensity Interval Training
Exercise will be performed at three sessions per week. All sessions will be supervised by a trained health or exercise professional.
BEHAVIORALModerate Intensity Interval Training
Exercise will be performed at three sessions per week. All sessions will be supervised by a trained health or exercise professional.

Design outcomes
Primary
| Measure | Time frame | Description |
|---|---|---|
| Change from Baseline in endothelial function as measured by flow-mediated vasodilation (FMD) | Baseline, 2 and 12 weeks immediately after the interventions ends, preceding an 'unhealthy' meal. | FMD will be measured using the guidelines reported by Corretti et al. The diameter of the brachial artery will be assessed using a high-resolution ultrasound device (Siemens SG-60, USA), equipped with a 7.5 MHz linear array transducer |
Secondary
| Measure | Time frame | Description |
|---|---|---|
| Change from Baseline in HDL Cholesterol | Baseline, 2 and 12 weeks immediately after the interventions ends, preceding an 'unhealthy' meal. | — |
| Change from Baseline in Triglycerides | Baseline, 2 and 12 weeks immediately after the interventions ends, preceding an 'unhealthy' meal. | — |
| Change from Baseline in Glucose | Baseline, 2 and 12 weeks immediately after the interventions ends, preceding an 'unhealthy' meal. | — |
| Change from Baseline in Heart rate variability | Baseline, 2 and 12 weeks immediately after the interventions ends, preceding an 'unhealthy' meal. | HRV will be performed according to current recommendations by European Society of Cardiology using an evaluated share-ware |
| Aortic pulse wave velocity (PWVao) | Baseline, 2 and 12 weeks immediately after the interventions ends, preceding an 'unhealthy' meal. | PWVao (m s-1) will be performed within 3 to 4 minutes with the oscillometric, occlusive device, the Arteriograph. The measurement will be taken in a supine position and were accepted if the quality indicator of the recordings was within the acceptable range (i.e., if the standard deviation \[SD\] of the beat-to-beat measured PWVao values was less than 1.1 m/sec). |
| Change from Baseline in muscular fitness | Baseline, 2 and 12 weeks immediately after the interventions ends, preceding an 'unhealthy' meal. | Muscular fitness (MF) will be assessed using handgrip test (maximum handgrip strength assessment) using a standard adjustable handle analogue handgrip dynamometer T-18 TKK SMEDLY III® |
| Change from Baseline in LDL Cholesterol | Baseline, 2 and 12 weeks immediately after the interventions ends, preceding an 'unhealthy' meal. | — |
| Change from Baseline in peak uptake of volume of oxygen | Baseline, 2 and 12 weeks immediately after the interventions ends, preceding an 'unhealthy' meal. | — |
| Change from Baseline in Blood Pressure | Baseline, 2 and 12 weeks immediately after the interventions ends, preceding an 'unhealthy' meal. | — |
| Change from Baseline in Body Mass Index | Baseline, 2 and 12 weeks immediately after the interventions ends, preceding an 'unhealthy' meal. | BMI will be calculated as the body weight in kilograms divided by the square of the height in meters. |
| Change from Baseline in Body Mass | Baseline, 2 and 12 weeks immediately after the interventions ends, preceding an 'unhealthy' meal. | — |
| Change from Baseline in Quality & satisfaction with life by SF Community - short-form survey (SF-12™) Colombian version | Baseline and 12 weeks immediately after the interventions ends, preceding an 'unhealthy' meal. | — |
| Augmentation index (AIx) | Baseline, 2 and 12 weeks immediately after the interventions ends, preceding an 'unhealthy' meal. | AIx (%) will be performed within 3 to 4 minutes with the oscillometric, occlusive device, the Arteriograph. The measurement will be taken in a supine position and were accepted if the quality indicator of the recordings was within the acceptable range (i.e., if the standard deviation \[SD\] of the beat-to-beat measured AIx values was less than 1.1 m/sec). |
| Change from Baseline in Flexibility using the sit and reach test | Baseline, 2 and 12 weeks immediately after the interventions ends, preceding an 'unhealthy' meal. | It will be determined using a maximum treadmill exercise test (Precor TRM 885, Italy) following the modified Balke protocol |
