ABSTRACT: Study of the dermatogliphy, somatotype and basic physical qualities of children from 9 to 14 years-old, from PID – Niterói, RJ according to the different stages of sexual maturity. In relation to dermatogliphy, in the sample of 96 children from both sexes, from a total of 360, it was found the predominance of the digital formula L > W. The averages and derived from the somatotype of the masculine sex, differ from the feminine sex that presents an increase in endomorphy. The mesomorphy to both sexes present a decrease according to the increase of the sexual maturity levels. The basic physical qualities test showed that the bigger the sexual maturity level, bigger are the VO2 máx Vertical Impulsion and Coordination values. It is concluded that the study is important to make new correlations possible.

Palabras clave: Identificación, Dermatoglifia, Somatotipo, Cualidades Físicas Básicas, Maduración INTRODUCTION It is incontestable the growth of sports in Brazil and in the world. Even with all of the technology advance and at the training methods, the identification and the selection of sportive talents shows errors due to paradigms so hard to be transposed. However, in spite of the science’s advance in all fields and the development each time more qualified of professionals involved with the physic activity, it continues the great difficulty in identifying the characteristics that will cooperate with the population’s health evolution and even so with the orientation and sportive selection (FERNANDES FILHO, 1997). Moskatova, quoted by Gomes (1998), said: “However more perfect the training technology is, it cannot amplify the pre-determination genetic of individual functional capacity in the athlete”. Moskatova’s considerations has turned out important ones, when we verify sporting icons as Oscar Schmidt (A Famous Basketball player in Brazil), Robson Caetano (A famous athletics in Brazil), Manoel Tobias (A famous football player in Brazil), and many others, that in spite of not having the support from one national athletics politic, without the quality of implements, materials and a necessary space to obtain an international project, they have gotten brands / marks, sportive reputation and financial only reached by sporting countries worried with the scientific and with the first places in the world sport. The goal of this study is to identify the dermatoglyphics characteristics, somatotypes and the basic physic qualities in different stages of sexual maturity among children with ages between 9 and 14 years old from Niterói – RJ, inscribed in the Athletics Starting Program – ASP / PID in Caio Martins Athletics Complex. The study is turned to be important in looking forward to identify the dermatoglyphics characteristics, somatotypes and the basic physic qualities according with the different stages of sexual maturity, meeting truth information among the characteristics of this population. The variables studied were the qualities in aerobic resistance physic, explosive strength, speed and coordination; the Dermatoglyphy; the somatotypes and the stage of sexual maturity. 316 The study is delimitated or restricted at the 360 students from the Athletics Starting Program – PID / ASP, in Caio Martins Athletics Complex, from different places in Niterói – RJ, from both sexes, with ages between 9 and 14 years old whose practice many different sporting modalities. Review of the Reading The sport’s characteristic physic quality identifications in training, and the adjust of this valence to the goals prescribed are basic for the sporting success. Tubino & col. (2003, p. 195) suits among the qualities indispensable to the athlete, the aerobic capacity. The speed is another physic quality indispensable to be measured in initial tests of physic capacity, in spite of being classified in displacement speed, reaction’s speed and the member’s speed (DANTAS 1995, p. 161). The level of coordination is especially important to obtain results on sporting games. According to Platonov & Bulatova (2003, p. 230), the improvement’s method of the motor coordination is primordial in athlete’s technique development, using a large scale of exercises with the aerobic resistance and / or anaerobic, are the most important physic qualities for the sporting practice. Besides, the identification importance on the physic’s value tests; the genetics characteristics, are relevant matter to estimate one individual. Regarding to the genetic aspects, the usage of previous knowledge on ability and the genetic tendency, allied to a phenotype contribution, it would assist, as the talent’s decision as to its development. As you have one methodology of genetic mark to the sporting valuation, it grows a possibility to find out individual ones with one genetic pre-disposition to determine experimental or sport’s modality. It distinguishes of three dermatoglyphic groups: bow (A), loop (L), and the verticule (W). The shape of the draws establishes one Fit Perf J, Rio de Janeiro, 2, 6, 316, Nov/Dec 2003 characteristic qualitative. The amount of lines – QL, and the sum of the total amount of lines inside the draw – SQTL, represents a characteristic amount. The intensity valuation of the draws occurs starting from the presence of deltas, and calculating the delta’s index – D10; bow_ the draw without deltas; Being one bow_ “0”, Loop_ “1” and the Verticule_ “2”; and yet, referring to the classification_ the sum of ten fingers, can be at the minimum “0” and the maximum “20”. It winds up that the simplest drawing is the bow one and the most complicated one is the verticule one (GLADKOVA, 1996). Norton & Olds (2000, p 139) emphasized that “the SOMATOTYPE is one method that allows one study significant about the example physic type for each sportive modality, through the Somatotyphology; it characterized the tendency to one determined sport. The observation of one set of information’s by the means of the Somatotyphology could make easier such task” In Recent studies, they are searching in planning the profile of athletes from different sports, in attempt to qualify the talent sporting selection ones. Medina & Fernandes Filho (2002) have shown one identification effort of genetic profile through the dermatoglyphic and from the somatotypes which characterizes the Volley ball Male Adult team in high efficiency of Brazil. The sexual maturity is showed on the adolescence as one decisive factor on the athletic development. The secondary sexual characteristics have already been studied and displayed regards with the biological maturation. The testosterone is produced in an elevated quantity through the puberty. This growth of sexual hormones concentration determines the changes of primary and secondary sexual characteristics during the puberty’s extension. The secondary observation in developing and characteristics is the most common tool used to evaluate the sexual maturity. It is exactly through the beginning of the puberty that the testicles, the penis, the mammal and the pubic hair shows modifications and, so, it allows the monitoring biological development of this phase of life. Methodology There was used the descriptive method (THOMAS & NELSON 2000, p. 34), with base in status study, on which looking for obtaining information near the existence conditions, regarding to the variables or conditions in one determined situation. – Not being inscribed officially on the Sportive Starting Program in Caio Martins Complex; – Not having enough average age between 9 and 14 years old; – Refused on participating on the study as a volunteer, without the return or financial advantage; – Being refused by the teachers / tutors of the offered tests; – Not agreeing, with the compromised terms assumed with the researchers; Research Ethics This task was accomplished in accordance with the Rules for the Research Accomplishment in Human beings, Resolution 196/96, from the Brazilian Board of Health from 10/10/1996. Sticking out that the research was submitted to one analyze from COMEP – Ethic and Research Committee. Involve Human Beings, from Castelo Branco University – RJ, which have been issued suitable concept. Proceedings of the collection of data The data were collected in Caio Martins Sporting Complex, Niterói – RJ, where the students from both sexes of the present study participate from the following sports: Basketball, volleyball, football of saloon, swimming, sportive gymnastic rhythmic, artistic gymnastic and judo. The collection was accomplished at the Gymnasium Pole sportive from Caio Martins Complex, Niterói, RJ, with exception of valuation of the stages of sexual maturity according with Tanner that it happened at the medical department, and the Volume test of maximum Oxygen, which it was accomplished on the football field, both in the Sportive Complex in Caio Martins, Niterói – RJ. In all tests were given specific information, the most objective possible ones, showing how it should be performed. The heating beforehand the tests or any type of trial were just allowed if it was adjusted on the protocol. All the individual ones stayed rest during the break of test accomplishments. To obtain the data necessary to the study, there were used the following protocols: – Genetic Mark Protocol – Dermatoglyphic Method – ID (CUMMINS & MIDLO 1942 quoted by FERNANDES FILHO 1999, p. 26); – Somatotypic Characteristic Protocol – Endo, Meson and Ectomorphy (HEATH & CARTER 1967 quoted by NORTON & OLDS 2000, p. 139); – Speed Test Protocol (30 m) – (POPOV 1986, quoted by MARTINS & GIANNICHI 1998, p.68); – 1000 meters Test Protocol – (VO2 max.) – (KLISSOURAS, quoted by FERNANDES FILHO, 2003); – Manual Pretension Test Protocol – Strength (Dynamometer) – (FERNANDES FILHO 2003, p. 189); – Coordination Test Protocol – Burpee – (JOHNSON & NELSON 1979, quoted by MARTINS & GIANNICHI, 1998, p.94); Sample After have been applied the rules of inclusion and exclusion, there was valuated one sample with 96 children, from a total of 360, from both sexes, with ages between 9 and 14 years old. Inclusion’s Criteria With the inclusion’s criteria, it had considered that the inscription in any sportive modality of the Athletics Starting Program in Caio Martins Complex, in Niterói, from average age students comprehended among 9 and 14 years old. Exclusion’s Criteria The exclusion’s criteria were: Fit Perf J, Rio de Janeiro, 2, 6, 317, Nov/Dec 2003 317 – Explosive Strength Test Protocol (Impvert) – (JOHNSON & NELSON 1979, quoted by MARTINS & GIANNICHI, 1998, p. 86). Picture 1 – Types of finger digital drawings Statistic of the Training There was accomplished one statistic treatment described enclosing an average and a standard bypass of data obtained on the somatotypes, dermatoglyphic and basic physic qualities in related to the sexual maturity stage. Conclusions and Recommendations The average corresponds to the values observed on the composed samples by children inscribed on the PID – Niterói, in many different rank of sexual maturity. It is convenient to say that, in despite of the sample valuated corresponds to an identification of parameter; it does not have any representative to the Municipal or State’s level. Regarding to the sex male ones (CHART 1) it is clear that, with the growth of age, the level of sexual maturity will also grow, the same it happens with the variables in weight and size. The O2’ variables maximum (aerobic resistance) and the Vertical Impulse (Explosive Strength of the inferior members) it also shows one growth on the amount, according with the larger sexual maturity in little boys studied. The motor coordination valuated through the Burpee tests also shows a slight growth, although this growth does not show one high variation among the maturational stages 1, 2 and 3. Nevertheless, it is verified one higher Preens ion Strength variation, according with the dynamometry, with the enlargement of the sexual maturity levels. The speed valuated through the 30 meters test, has showed an improvement among the levels 1 and 2, however it keeps in one constant platform among 2 and 3 levels of sexual maturity (Chart 1). The somatotypes has its endomorph and mesomorph components showing the decrease in related to the growth of sexual maturity length, mean while the ectomorpho component grows, due to the decrease of corporeal fat and the growth of testosterone’s hormone levels composition, which it helps, besides the appearance of the males sexual characteristics, the growth of strength among others (chart ). On the Chart 2 related to the female sex, it is verified that, as in the male’s sex, the growth of sexual maturity stages according with the increase of age, weight and size, as well as the progressive Table 1 – Median and standard deviation of the studied characteristics in relation to Tanner in male sex Tanner Age Weight Stature VO2máx Impvert Burpee Din 30m Endo Meson Ecto 1 9.95±1.23 38.85±12.61 139.20±10.31 30.84±12.24 23.93±3.89 4.20±0.89 17.15±12.28 6.48±0.78 4.66±2.44 5.65±2.00 2.23±1.60 2 11.76±1.20 44.34±7.30 151.26±7.61 38.84±11.93 27.29±7.90 4.47±0.80 29.47±16.05 5.74±0.47 3.73±1.73 5.52±1.09 2.86±1.22 3 13.43±0.65 55.58±10.66 164.54±6.88 44.46±4.56 34.51±5.99 4.50±0.65 50.86±18.92 5.77±0.56 3.08±1.42 4.68±1.17 3.23±1.41 Source: Macêdo & Fernandes Filho (2003) Table 2 - Median and standard deviation of the studied characteristics in relation to Tanner in female sex Tanner Age Weight Stature VO2máx Impvert Burpee Din 30m Endo Meson Ecto 1 9.95±0.85 33.21±9.46 135.60±7.91 20.76±7.16 25.40±3.89 4.10±0.74 5.30±6.75 6.69±0.66 4.54±1.86 4.43±1.61 2.74±1.77 2 12.20±1.21 45.50±11.19 152.93±7.11 34.54±9.38 27.03±5.86 4.60±0.74 26.20±9.34 5.93±0.74 4.15±1.54 4.31±2.07 3.21±1.76 3 13.41±0.87 55.11±11.34 160.76±5.97 37.38±9.33 28.09±5.11 3.94±0.66 35.94±9.86 6.20±0.51 5.01±1.44 4.19±1.24 2.62±1.21 Source: Macêdo & Fernandes Filho (2003) 318 Fit Perf J, Rio de Janeiro, 2, 6, 318, Nov/Dec 2003 the stage 1 to 2, however it shows the decrease on the 3rd stage in related to the 2nd one. However, such difference is not so big among the stages 1, 2 and 3, as it also happens on male sex. Picture 2 - Development phases of the pubic hair and the genital development The speed shows a better among the 1st and the 2nd stages on sexual maturity and the decreasing on the 2nd stage to the 3rd one. However, as it happens on the male sex, this decreasing is not so big (Chart 2). On the contrary of the male sex, at the somatotypes the female sex (CHART 2) shows one growth of endomorph according with the sexual maturity level growth, due to the growth of composition female’s sexual hormones level, which it helps the accumulation of corporeal fat in characteristic regions of female sex. The Ectomorphy shows one growth between the 1st and the 2nd stages of sexual maturity and the decreasing between the 2nd and the 3rd stages, on which it can manage to one tendency on later stages. It is recognized the importance of the Dermatoglyphy as one of the variables to the orientation and selection of sportive talent ones, it becomes primordial the need to obtain this profile in any characteristics on human being identification study.

The digital formula L>A shows the levels 1, 2 and 3 of sexual maturity, according to Tanner, in spite of one low number of representatives (Graphic 1). it is necessary not only in working with determined average ages, divided in categories, as also take in consideration the different sexual maturity of stages on individual analyzed ones. On the data Dermatoglyphy collected of female sex, there is one predominance on the levels 2 and 3 of the sexual maturity protocol, according to Tanner, the digital formula L>W, while the level 1 there was the predominance of the digital formula W>L, The digital formula ALW and L=W shows on the levels 1 and 2 and L>A shows on levels 1, 2 and 3 of the sexual maturity in low percentages (Graphic 2). The investigation about the applying this study it can not stay restricted just to identify the profiles of the studied ones, but the correlation of the same above can create precious information to each sexual maturity stage, which certainly could cause on making a map of work to the sporting development, which it will cooperate in an effective way to the success of Brazil’s sports. In both sexes the digital formula predominant was the L>W, in spite of the male sex shows with more frequency on the levels 1 and 2 of sexual maturity from Tanner, mean while , on the female ones, it shows with more frequency the levels 2 and 3. The children’s profile identification and the comparison of the same profile of one sportiest of a high qualification will have to be accomplished with the maximum criteria, in that way the results obtained will be used as a tool from all professionals that act on the sports in general. After the identification of the characteristics proposed on the research, it is important to emphasize that, in former studies, Guba & Tchernova (1995) have exposed that the lessen amount of lines it contains, the more speed and strength it will have; Arutiohian (1998) mentions the balance relates with a few quantity of lines and with a low intensity of drawings. Like that, it justify the study of Dermatoglyphy, the characteristics Somatotypic and the basic physic qualities when looked for a higher number of possibilities of skills on the valuation, as on the search for genetically super enlarger to one sportive segment or to one future symptom of these individuals.

The results are showing a great influence on the variations of amount from the tests of basic physic qualities as higher it is the sexual maturity stage showed by the individual one. Knowing the dermatoglyphic standards from the individual ones of the sample showed the genetic potential of each one studied, we can say that, this genetic potential, is not always showed on the basic physic qualities tests, therefore it will depend on the sexual maturity stages that the individual is found and, mainly, the Phenotype (environment) that act straight on the individual.
