Brief Summary

This study evaluates the effects of physical exercise through active videogame in the microcirculation, macrocirculation, cardiorespiratory function and physical fitness in overweight adolescents. For that, they will be randomized into two groups, one being a control group and the other intervention group. The randomization will be made by school. The intervention group will perform the physical exercise through the active video game, three times a week, for 50 minutes, during 8 weeks. Reassessments will be performed before and after the intervention to evaluate the outcome variables.

GroupInterventionDescription
Active video gameActive video gameThe adolescents will be submitted to physical activity with active video game for 50 minutes, 3 times a week, for a period of eight weeks. The XBOX360® platform will be used with the Kinect accessory (Microsoft®) and Just Dance will be the selected game. The music used for intervention will be previously selected, including those that can lead to moderate intensity, and assembled in blocks of 10. For each week, a new block and challenges must be elaborated to increase the motivation to carry out the physical activity.
Primary Outcome Measures
NameTimeMethod
Microcirculatory blood flow during rest (RF)10 minutes

Variable measured in perfusion units (PU), obtained during the first five minutes of the microcirculation evaluation protocol by Cutaneous Laser Doppler Flowmetry (LDF).

Maximum blood flow (MF)10 minutes

Peak blood flow during post-occlusive reactive hyperemia (PORH), expressed in perfusion units (PU).

Area of hyperemia10 minutes

Scalar numerical variable corresponding to the geometric area related to the process of reflex hyperemia after the mechanism of arterial occlusion, expressed in perfusion units (PU).

Relationship between peak flow during PORH and resting blood flow.10 minutes

Continuous variable, MF / RF ratio expressed in perfusion units (PU).

PORH index10 minutes

Scalar numerical variable related to reactive hyperemia after the arterial occlusion. mechanism, expressed in perfusion units (PU)

Occlusion area10 minutes

Scalar numerical variable corresponding to the geometric area related to the region without reflex hyperemia after the arterial occlusion mechanism, expressed in perfusion units (PU).

Femoral Intima Media Thickness30 minutes

Variable measured in millimeters, obtained by the maximum value of 3 measurements made in the right femoral artery and 3 measurements in the left femoral artery. Performed with a portable device (General Eletric®, LogicE® model), with a high definition linear transducer.

Carotid Intima Media Thickness30 minutes

Variable measured in millimeters, obtained by the maximum value of 3 measurements performed in the right common carotid artery and 3 measurements in the left common carotid artery. Performed with a portable device (General Eletric®, LogicE® model), with a high definition linear transducer.

Cardiorespiratory Fitness - Maximum oxygen consumption10 minutes

Numerical, continuous, expressed in liters per minute per kilogram (l/mim/kg), obtained indirectly through the 20-meter run test.

Flexibility5 minutes

variable numeric, continuous, expressed in centimeters, obtained through the sit-and-reach test.

Abdominal resistance2 minutes

Secondary Outcome Measures
NameTimeMethod
Triglycerides5 minutes

Continuous numeric variable expressed in mg/dL.

nutritional status10 minutes
