There is growing interest in identifying morphological, motor, maturation characteristics, as well as their changes, of children and adolescents in systematized training in various sports. Knowledge of these characteristics is important for coaches and researchers because they provide parameters for assessing youth development during training. For track and field, studies on the category under 16 are scarce. Thus, the objectives of this study are to describe the profile and to design a percentile table of morphological, motor, maturation and eventspecific variables of under 16 athletes. 105 young athletes were evaluated on two consecutive days. On the first day, an anamnesis of athletes and coaches was performed. Anthropometric and anaerobic measurements were analyzed in shot put, long jump, 800 m run. On the second day, flexibility, vertical impulse, upper limb strength, speed and maximal aerobic speed were evaluated. The biological maturation was evaluated by the percentage of the predicted adulte height. A table with percentiles was prepared with the data of all athletes. Another table with the results of the whole group plus mean and standard deviation was prepared. A last table was prepared containing data divided by group of sports events. The morphological variables presented differences between the groups as to body mass, BMI and sum of skinfolds. Significant differences were observed only for the motor variable MAS. No significant differences were observed only for long jump. When divided by groups, it was evident that throwers are different from the other athletes in some morphologic variables and in specific sports events.

O estudo investigou diferenças na motivação de atletas do atletismo, comparando grupos de provas, nível competitivo, categoria e sexo. Avaliamos a motivação através do questionário (SMS-BR28) de 133 atletas, 56% do sexo masculino e 44% do sexo feminino. Não teve diferenças significativas entre grupos de provas e nível competitivo, nível de significância (P<0,05). Houve diferença significativa comparando à motivação de juvenis e adultos vs pré-mirim e mirim. Concluímos que a motivação para treinar Atletismo independe da prova disputada, atletas juvenis, sub-23 e adultos são mais motivados intrinsecamente que os atletas pré-mirim e mirim, em relação ao sexo os homens tem maior motivação extrínseca que as mulheres.
