其他摘要：The objective of this study was to analyse the changes on gross motor development after five (T5), ten (T10) and 30 (T30) months of swimming or soccer practice. The study sample consists of 33 preschool - aged boys (4.8±0.5 yrs.): 11 soccer practitioners; 11 swimming practitioners; 11 controls (no previous involvement in sports). The Test of Gross Motor Development – Second Edition was used to assess common gross motor skills (locomotion, object control skills). Both experimen tal groups improved significantly in their gross motor quotient and the standard scores for locomotion and object control skills between T5 and T10. At T10, all soccer practitioners have already reached the maximum descriptive rating for the gross motor qu otient. Between T10 and T30, swimming practitioners were able to improve the standard scores for object control skills. Main results showed a positive impact of swimming and soccer participation in motor proficiency.
