Brief summary
There will be a three-month intervention with two groups: judo training and ball games, twice a week, for 50 minutes. The sample will consist of children and adolescents with low socioeconomic status, participants of a philanthropic institution, aged between 6 and 15 years, who will be randomized in the two groups mentioned above. Motor skills, physical fitness, cardiovascular parameters and questionnaire assessing socioeconomic status, quality of life, physical activity level, screen time, sleep quality, back pain, food intake and body image dissatisfaction will be evaluated.
Detailed description
The sample will be of 66 participants, randomized into two groups 33 in judo and 33 in ball games. According to the sample calculation based on the study of Bala and Drid (2010) title Anthropometric and Motor Features of Young Judoists in Vojvodina, who analyzed motor skills in young judokas and untrained control, using the variable slalom with 3 balls (functional coordination and the age group from 11 to 13 years. In which the difference between the means was of 36.86 and the standard deviation of 53.78, with the power of the 80% test and significance of 5% in boys. In girls the sample calculation was the same number (33 for group) using the same variable slalom with 3 balls (functional coordination and the some age group from 11 to 13 years, the difference between the means was 10.45 and the standard deviation of 15.05, with the power of the 80% test and significance of 5% The present study was approved by the Research Ethics Committee of FCT/UNESP (CAAE: 26702414.0.0000.5402), with the number of opinion 549.549. Interventions Judo Training Judo intervention will take place twice a week, lasting 50 minutes per session, divided into general exercises: warm-up and stretching specific to the sport; Specific exercises of the sport: shock absorption, falls cushioning (Ukemi-waza), immobilization techniques (hon-kesa-gatame and tate-shiho-gatame) and projection (o-soto-gari, o-goshi, ashi-guruma, koshi-guruma, tai-otoshi and others); And fight simulation: randori. Ball Games The Ball Games will take place twice a week, with a duration of 50 minutes per session, divided into general exercises: heating and specific stretching with ball; Specific exercises of the sport: fundamentals of sports with ball, exercises with ball; And games: games will be given at the end of the lesson to work out all the fundamentals and specific exercises in general. Statistical Analysis We will perform the Shapiro-Wilks normality test, analysis of variance (ANOVA) of repeated measures and the effect size will be calculated by Eta Squared, all using SPSS Software version 13.0 and adopting a significance of 5%.

Design outcomes
Primary
| Measure | Time frame | Description |
|---|---|---|
| Change of Equilibrium | Baseline and three months of follow up | The motor skills will be by means of the Körperkoordination Test für Kinder (KTK) (Kiphard, Schilling, 1974) test battery consisting of four stations, and Equilibrium Beam is one, in which the evaluated one must walk on backs of three different widths, measured in how many steps on the toolbar. |
Secondary
| Measure | Time frame | Description |
|---|---|---|
| Change of Lateral Jumping | Baseline and three months of follow up | The motor skills will be by means of the Körperkoordination Test für Kinder (KTK) (Kiphard, Schilling, 1974) test battery consisting of four stations: Lateral Jumping is one, consisting of the execution of the maximum of lateral jumps in 15 seconds, measured in number of jumps. |
| Change of Platform Transfer | Baseline and three months of follow up | The motor skills will be by means of the Körperkoordination Test für Kinder (KTK) (Kiphard, Schilling, 1974) test battery consisting of four stations: Platform Transfer the maximum transfers in 20 seconds. |
| Change of Monopedal jump | Baseline and three months of follow up | The motor skills will be by means of the Körperkoordination Test für Kinder (KTK) (Kiphard, Schilling, 1974) test battery consisting of four stations: Monopedal jump is one, in which the child jumps with one leg at a time trying to reach the maximum height, measured by means of a score adding the score of the two legs. |
| Change of Heart Rate | Baseline and three months of follow up | Heart rate will be measured using an Omron oscillometric device validated for this population (Zanuto et al., 2016), measured in beats per minute (bpm). |
| Change of Blood Pressure | Baseline and three months of follow up | Systolic and diastolic blood pressure will be measured using an Omron oscillometric device validated for this population (Christofaro et al., 2009), measured in millimeters of mercury (mmHg). |
| Change of Heart Rate Variability | Baseline and three months of follow up | he heart rate variability was evaluated by means of a Polar frequency meter model RS800, in which it measures linear time and frequency domains and nonlinear domains such as the Poincaré Plot. |
