Aerobic capacity is a vital factor for soccer achievement. Disclose by professionals over VO2max of 60 ml/kg/min recommended as the minimum fitness condition for male soccer players to play at leading levels. Founded on the principle kinetics analyse, which confirms that among competitive soccer players, wing-backs and central midfielders cover long distances at high speed, then by defenders and attackers. Our objective is to test 180 well-trained male senior player, first division Algerian Championship. Dived biased on their postgame. Controlled at the end of the preparatory phase before the start of the Algerian Championship 2016-2017. Tested by Cooper tests to estimate their VO2max and body fat percent (BFP) and index body mass (BMI). As simple tools to control their optional body weight relates to their aerobic fitness. Our results support the uniform of Algerian training programmes aerobic capacity. Conclude through the present founded on kinetics analyse, which confirmed that in competitive soccer players, wing-backs and central midfielders cover long distances at high speed, then by defenders and attackers. Our results show that VO2max L/min was insignificant based on the postgame, where this result confirms to users the negative effect of the moderate-intensity exercise intervention and its consequences on develops of recommended levels of VO2max relative to proper individuals programme fitness helping players to manage body weight or stroke. Disclose by professionals over VO2max of 60 ml/kg/min recommended as the minimum fitness condition for male soccer players to play at leading levels.

“…Estos métodos de predicción también han sido comparados con estudios longitudinales. En un estudio desarrollado por Silva et al (2016) en adolescentes deportistas, se comparó el valor de estatura adulta predicha por el método KR y cuatro años después se midió la estatura real alcanzada, sin encontrarse diferencias entre lo predicho y observado. Resultados similares se encontraron en atletas donde se validó el método de TW, el cual es una versión anterior al método TW3, para la estimación del PEA en atletas caucásicos masculinos, sin encontrarse diferencias entre el valor predicho y el valor real alcanzado de estatura final (Ostojic, 2013).…”

FLORES, O. L. A.; DE LEÓN, F. L. G.; BARRIGAS, C. F. & FRAGOSO, M. I. C. J. Comparación de tres metodologías para estimar el porcentaje de estatura adulta en niños y niñas de 7 a 16 años. Int. J. Morphol., 37(2):632-640, 2019.RESUMEN: El porcentaje de estatura adulta (PEA) es un indicador del estado de maduración, que refleja la variación en la tasa y progreso de crecimiento. Existen diversos métodos para estimar la estatura adulta, sin haberse documentado en la literatura de manera concreta sus similitudes o diferencias. Los objetivos del presente trabajo fueron comparar tres métodos de estimación del PEA, identificar cambios seculares en niños y adolescentes y establecer valores de referencia del PEA para población portuguesa. Se midieron en 799 niños y 736 niñas, de 7,0 a 16,49 años, la edad ósea, el peso y la estatura, para estimar el porcentaje de estatura adulta por las metodologías TW3, KR y RWT. Los valores del método TW3 del presente estudio, fueron comparados con los reportados en décadas atrás para identificar cambios seculares. Se utilizo un ANOVA de medidas repetidas para estimar las diferencias entre los métodos en el presente estudio, así como gráficas de Bland y Altman. Se utilizó la prueba de Kruskal-Wallis para analizar las diferencias entre los valores encontrados en la presente investigación y los presentados en décadas atrás en otros estudios. No se encontraron diferencias entre los métodos TW3 y KR en los diferentes grupos de edad cuando se clasificaron los sujetos por edad cronológica, en ambos sexos (P>0,05). Así mismo, no se observaron cambios seculares en el PEA (P>0.05). Los métodos TW3 y KR pueden ser intercambiables entre sí, debido a que no presentan diferencias en la estimación a diferentes edades y en ambos sexos. Además, no existió cambio secular en la estimación de PEA por estas metodologías, lo que las hace útiles en la actualidad.

Skeletal age (SA) is considered the gold standard to assess the degree of maturation and has been widely used in sports, education and public health areas; however, it requires sophisticated equipment and well-trained technicians. Therefore, it is important to develop non-invasive methods for its evaluation. The aim was to develop an equation to predict SA using the percentage of adult height. SA was measured by Tanner-Whitehouse-3 method, and the percentage of adult height was estimated by two methodologies: Tanner-Whitehouse-3 method (P-TW3) and Khamis-Roche method (P-KR) using 839 schoolchildren of both sexes. Linear regression was used for predicting SA from P-TW3; then P-TW3 was replaced in the equation for P-KR value. Bland–Altman graphs, interclass correlation coefficient and Kappa index were used as validation tests. Model showed a SA predictive capacity of 93.2% in boys and 96.8% in girls. The average differences between SA measured and SA predicted by P-TW3 was 0.0504 (± 0.664) in boys and 0.0144 (± 0.435) in girls (P = 0.229 and 0.667, respectively). When P-TW3 was replaced for P-KR value in the equation, the average differences were − 0.0532 in boys and 0.0850 in girls (P = 0.509 and 0.167 respectively). The present model, based on the percentage of adult height, showed an adequate estimation of SA in children and adolescents and it can be used in the absence of bone X-ray equipment, in healthy boys aged 9 to 15 and girls 8 to 13.
