The sample comprised in the research was represented by 57 students (29 girls (145.4±7.28 cm, 38.97±9.89 kg)) and 28 boys (143±6.55 cm, 38.61±8.22 kg)), aged between 10 – 12 years old. The types of measurements included in the study were as follows: anthropometrical measurements and biomotor measurements (standing long jump, abdominal endurance, motion velocity, and resistance). Results. Among girls, the analysis of Pearson’s correlation between the series of results indicates significant connectionsbetween the trials of standing long jump and 30-m speed run (r = 0.45, p=0.012), resistance run and torso raises, respectively (r = -0.57, p=0.001). Among boys, the significant differences were recorded between the BMI and the standing long jump (r=-0.39, p=0.036), 30-m speed run and standing long jump (r=-0.56, p=0.001) and 30-m speed run and 200-m resistance run (r=0.42, p=0.022).
