- 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.

Group Intervention Description Active video game Active video game The 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
Name Time Method 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 hyperemia 10 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 index 10 minutes Scalar numerical variable related to reactive hyperemia after the arterial occlusion. mechanism, expressed in perfusion units (PU)
Occlusion area 10 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 Thickness 30 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 Thickness 30 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 consumption 10 minutes Numerical, continuous, expressed in liters per minute per kilogram (l/mim/kg), obtained indirectly through the 20-meter run test.
Flexibility 5 minutes variable numeric, continuous, expressed in centimeters, obtained through the sit-and-reach test.
Abdominal resistance 2 minutes numerical, continuous variable, expressed in absolute number of abdominal performed in one minute, obtained through the sit-up test.
- Secondary Outcome Measures
Name Time Method Triglycerides 5 minutes Continuous numeric variable expressed in mg/dL.
nutritional status 10 minutes measured weight (kilogram) and height (centimeters) for calculating body mass index, expressed in Kg/m\^2.
Blood Pressure 15 minutes measurement blood pressure (mmHg) through digital tensiometer OMRON.
abdominal adiposity 5 minutes measurement of abdominal circumference with inelastic tape, in centimeters.
Lung Function - Forced Expiratory Volume in the first second 20 minutes Evaluated by spirometry, with a computerized ultrasonic portable spirometer, with flow sensor, Easy One® brand, with internal Winspiro Software upgrade version 1.04 for connection to computer. The course will provide the values of Forced Expiratory Volume in the first second expressed in liters (l) and in percentage of the predicted value individually (%pred).
Lung Function - Total Lung Capacity 20 minutes Evaluated by spirometry, with a computerized ultrasonic portable spirometer, with flow sensor, Easy One® brand, with internal Winspiro Software upgrade version 1.04 for connection to computer. The course will provide the values of Total Lung Capacity expressed in liters (l) and in percentage of the predicted value individually (%pred).
Strength of the inspiratory and expiratory muscles 20 minutes Evaluated by digital manovacuometry, through a digital manovacuometer MVD300, will be obtained the measurement of respiratory maximum static pressures, maximum inspiratory pressure regarding inspiratory muscle strength and maximum expiratory pressure regarding the expiratory muscles. Both will be expressed in cmH2O.
Fasting blood glucose 5 minutes Continuous numeric variable expressed in mg/dL.
C-reactive protein 5 minutes Continuous numeric variable expressed in mg/dL.
Total cholesterol 5 minutes Continuous numeric variable expressed in mg/dL.
High density lipoprotein (HDL) cholesterol High density lipoprotein (HDL) cholesterol 5 minutes Continuous numeric variable expressed in mg/dL.
