Evaluation of the effects of training in children practicing field soccer from Mangueira Olympic Center

The aim of this study was to evaluate the differences, found after 12 weeks of training, in the development of the physical qualities of two groups of children practicing soccer at Mangueira Olympic Center, Both groups were in the third stage of biological maturation, and were submitted to two different methodologies, during the stage of basic formation: the traditional and the maturational. The sample was composed by 30 male infants. For the evaluation of the biological maturation the board of pictures" by Tanner was used (1962), for the self evaluation protocol proposed by Matsudo & Matsudo (1991). For the evaluation of the physical qualities the following protocols were used: coordination (test of coordination of Burpee), flexibility (angular goniometric test), dynamic power (test of manual dynamometric pressure), explosive power (test of vertical impulse) and speed (speed test of 30 meters sprint). The statistic procedure used was the Student’s t-test and Student’s t-test (independent protocol for inter-groups analysis). The study established p≤0.05 to statistic significance. . When we compared G1 with G2 observed the results do D% and p-valor, respectively: coordination (D% = 2,91%; p= 0,00), dynamic power (D%= 3,01; p=0,49) and explosive power (D%= 1,03; p=0,63), flexibility (D% = 4,39%; p= 0,00), aerobic resistance (D% = 0,91%; p=0,00) and speed (D% = -0,96; p=0,00). The results allowed concluding that the experimental group, which used the maturational methodology, showed significant statistic differences in the variables coordination, flexibility, aerobic resistance and speed compared to the traditional group.
