Many studies indicate that an adequate physical fitness is an important marker for a healthy body and a healthy mind. The aim of the study was investigate the level of physical fitness of students aged 11-13. Depending on the results, we will determine the type of measures to propose in order to improve the obtained data.
251 volunteer students participated in this research, including 95 boys and 156 girls aged 11 to 13, who participated in the physical education class two times a week. Subjects underwent six anthropometric characteristics and five physical tests. For the statistical analysis the mean, standard deviation, and multiple comparisons were used in order to find the differences between genders, using Anova and Bonferoni Test for differences between certain age groups. Anthropometric measurements included height, weight, arm span, waist, hip, body mass index and physical testing as agility, balance and strength.
The findings suggest some differences between male and female subjects, as well as between age groups, namely boys obtained higher mean results compared to girls.
