The aim of this study was to verify differences between boys contrasting in futsal practice level groups on gross motor coordination and growth indicators. A sample of 196 boys aged 11 to 14 years was measured for anthropometric variables and Körperkoordinationstest für Kinder (KTK). Results revealed that there were no significant associations of the futsal practice level on growth parameters. On the other hand, ANCOVA results (chronological age as a covariate) indicated that boys participating in futsal practice ≥ 2 days/week had significantly better performances in jumping sideways, hoping for height, and total score of KTK than their less practicing counterparts. These findings encourage the most frequent practice of sports for the development of gross motor coordination. Keywords: Motor skills; Adolescent; Maturation; Sport.

Context:Croton sp. are plants with a well-reported antimicrobial activity. Croton limae A.P. Gomes, M.F. Sales P.E. Berry (Euphorbiaceae), known as ‘marmeleiro-prateado’, is commonly used to manage abdominal pain in Brazil.Objective: This work evaluates the phytochemical composition, antimicrobial and modulatory activities of the essential oil of C. limae leaves (EOCL).Materials and methods: The minimum inhibitory concentration (MIC) and the modulation of the antibiotic activity were determined using a microdilution method. The concentration of EOCL ranged between 512 and 8 μg/mL. Staphylococcus aureus, Escherichia coli, Pseudomonas aeruginosa, Klebsiella pneumonia, Candida tropicalis, C. krusei and C. albicans strains were used in the MIC and modulation assays. The antibiotics, amikacin, gentamicin and neomycin, and the antifungals, amphotericin B, benzoylmetronidazole and nystatin, were used in concentrations ranging between 2500 and 2.5 μg/mL. The phytochemical analysis of the EOCL was performed through gas chromatography coupled to a mass spectrometer (GC/MS).Results: Only Staphylococcus aureus was inhibited by a clinically relevant concentration of EOCL (MIC 512 μg/mL). Synergism between the EOCL and amikacin against S. aureus (9.76 μg/mL) and E. coli (39.062 μg/mL); neomycin against E. coli (2.44 μg/mL); and benzoylmetronidazole against C. krusei (256 μg/mL) were observed. The GC/MS analysis identified cedrol, eucalyptol and α-pinene as the main compounds of EOCL.Conclusion: EOCL inhibited the growth of S. aureus and potentiated the antibiotic and antifungal effects of drugs against all bacterial and Candida strains, respectively.
