Weight measured to the nearest 0.01 kg by Seca 767 scale. The first before the games, the second after the games.

Weight measured to the nearest 0.01 kg by Seca 767 scale. Z scores were calculated using national data for Turkish children. The first before the games, the second after the games. Positive z-scores indicates the number of standard deviations of the child above the mean of the population of the same age, whereas negative z-scores indicates the number of standard deviations of the child below the mean of the population of the same age.

Body Mass Index calculation of both groups before the games and after the games.

Weight and height were measured to the nearest 0.01 kg (Seca 767) and 0.1 cm (Seca 220). BMI Z-scores were calculated using national data for Turkish children derived from values obtained from calculations with Quetelet index. The first before the games, the second after the games. Positive BMI z-scores indicates the number of standard deviations of the child above the mean of the population of the same age, whereas negative z-scores indicates the number of standard deviations of the child below the mean of the population of the same age.

The biceps, triceps, suprailiac and subscapular regions skinfold thicknesses were measured by Holtain caliper at the beginning of and after the games. Durnin-Womersley formula was used to calculate body densities. Then fat ratio of whole body was derived from the Siri equation by integrating body densities obtained by Durnin-Womersley formula.

Determination of visual reaction times after games in intervention groups, and control groups. First before the games, second after the games.

The scale "Children and Youth Physical Self Perception Profile (CY-PSPP)" assessed the children's self-percetion about sports competence subscale in both groups at the beginning and at the end of protocol. The subscale was assessed by 6 questions with four ordinal levels (1-4) of response. Minimum and maximum total scores change between 6 to 24 for the subscale. Higher scores mean a better score.

The subscale was assessed by 6 questions with four ordinal levels (1-4) of response. Minimum and maximum total scores change between 6 to 24 for the subscale. Higher scores mean a better score.

For Sports category, there were 5 games of boxing, tennis, golf, baseball, and bowling. Thus, each child was evaluated after every single game by five bipolar scale questions. Questions 1 and 4 were starting from positive to negative answers (left to right) and scored as 7-1. Scale scores were determined by calculating the mean. All scale scores were summed to calculate the Category score. The higher the score, the better the enjoyment in this category.
