Introduction: Maturation is a biological phenomenon inherent to the human being that acts alongside environmental factors in its relationship with the development of children and adolescents.Objective: To analyse the motor skills during maturational stages of female adolescents. Methods:This study included 133 female adolescents aged between 10 and 17 years from federal schools in the city of Rio Branco, State of Acre, Brazil. Sexual maturation was evaluated using Tanner's self-assessment. Motor skills were assessed using the following tests: strength (Jump Test); coordination (Burpee Test); balance (Flamingo Test); flexibility (Sit and Reach Test); agility (Shuttle Run Test). The data were analyzed using SPSS 20.0 software through analysis of variance. The significance level was fixed at 5%. Results:No significant statistical results were found for strength, agility, balance and flexibility, evidencing that maturational advances did not influence these skills. In the coordination variable, significant results were obtained. Conclusion:The results of this study suggest that maturational advancement in adolescents does not influence strength, agility, balance or flexibility. However, it does influence coordination, presenting better performance at stage P2.

-Intermanual Transfer of Learning (IMTL) is the ability to learn a certain skill in an easier way with one hand after that skill has been learnt by the opposite hand 1 . This research aimed to investigate IMTL in a Fine Manual Dexterity (FMD) task in subjects presenting different Hand Preference (HP). The sample comprised 882 right and left-handers, both genders, aged 6 to 95 years old. The Dutch Handedness Questionnaire 2 was used to assess HP and the Purdue Pegboard Test 3 evaluated FMD. Direction and intensity of HP, Direction of Transfer (DT), gender, age and nationality were analyzed. IMTL changed according to DT and age, tending to be asymmetric, holding high values in the direction of Non-Preferred Hand (NPH) to Preferred Hand (PH). Children had got a higher IMTL rather than youngsters, adults and old adults with significant differences in adults.
