dc.description.abstractINTRODUCTIONTennis is among of the most popular sports. According to International Tennis Federation ITF more than 60 million people practice this sport and 200 countries are members of ITF (Pluim et al., 2006) Hence, tennis is a sport extensively studied. Most of the scientific literature focused on physiological (kovacs, 2006; 2007), biomechanical variables (Elliot et al., 2003), physical performance, (Fernandez-Fernandez et al., 2006; 2015; 2016) and prevention and treatment of injuries (Bylak & Hutchinson, 1998).Studies about skeletal maturation in youth tennis players are still limited, and are mainly related to growth status (Malina, 1994; Myburgh, et al., 2016a) or maturity-associated variation in functional characteristics (Myburgh et al., 2016b).METHODSA single anthropometrist measured height, sitting height body mass in each country. Chronological age was calculated as the year between the date of birth and the day of the x-ray examination, the radiograph was taken by an onsite trained and certified technician in each country.ParticipantsThe sample is composed of 80 male tennis players aged 8.69-16.79. They were from Great Britain, Portugal and Colombia. Skeletal maturationMature state was obtained considering FELS method and the fact that a skeletal age of 18.0 years corresponds to the mature state. The respective classification for TW3 is 16.5 years (score=1000) for males. Statistical analysisDescriptive statistics were calculated for the total sample to chronological age, stature of the father, stature of the mother and anthropometry, equally descriptive statistics for maturity offset, estimated age at the peak height velocity, predicted mature (according to concurrent protocols) and skeletal aged determined by concurrent protocols. Analysis of variance ANOVA was used to compare Fels and TW3 SAs in players who were not classified as skeletally mature by either method.RESULTSMean of chronological age is 12,91 years, stature 159,86cms and body mass 49,70kgs. Mean of skeletal age determined by TW2 is greater than means of TW3 and Fels methods, and Fels SA mean is greater than TW3 SA. Among players who were not skeletal mature by either method (n= 72) The difference between mean Fels and TW3 SAs are significant (F=37,50 , p<0,001).CONCLUSIONSThe present study examined the agreement between concurrent protocols for determination of skeletal age (FELS and TW3) in a sample of male tennis players. Mean of skeletal age determined by Fels was greater than TW3 SA. Among players who were not skeletal mature by either method the difference between mean Fels and TW3 SAs was significant (F=37,50 , p<0,001.To measure skeletal ages have impact on the selection, development and progression in the talent, as well as on long term training. Competitive youth tennis needs speed, agility and aerobic capacity to competition (Kovacs, 2007).eng
dc.description.abstractINTRODUCCIÓNEl tenis es uno de los deportes más populares. Según la Federación Internacional de Tenis (ITF), más de 60 millones de personas practican este deporte y 200 países son miembros de la ITF (Pluim et al., 2006). Por lo tanto, el tenis es un deporte ampliamente estudiado. La mayor parte de la literatura científica se enfocó en las variables biomecánicas (Elliot et al., 2003), fisiológicas (Fernández-Fernández y cols., 2006, 2015, 2016) y en la prevención y tratamiento de lesiones (Bylak y Hutchinson, 1998).Los estudios sobre maduración esquelética en jugadores de tenis juveniles son todavía limitados y están relacionados principalmente con el estado de crecimiento (Myburgh et al., 2016b).MÉTODOSUn solo antropometrista evaluo la altura, la masa corporal sentada para los participantes de cada país. La edad cronológica se calculó como el año entre la fecha de nacimiento y el día del examen de rayos X, la radiografía fue tomada por un técnico capacitado y certificado en cada país.ParticipantesLa muestra está compuesta por 80 jugadores masculinos de tenis de 8,69-16,79. Eran de Gran Bretaña, Portugal y Colombia.Maduración del esqueletoEl estado maduro se obtuvo considerando el método FELS a una edad esquelética de 18,0 años. La clasificación respectiva para TW3 es de 16,5 años (puntuación = 1000) para los varones. Como lo estipulan estos dos protocolosAnálisis estadísticoSe calcularon estadísticas descriptivas de la muestra total a la edad cronológica, estatura del padre, estatura de la madre y antropometría, estadísticas igualmente descriptivas para el desfase de madurez, edad estimada del pico de velocidad de crecimiento, predicción de la estatura final (según diferentes protocolos) y edad esquelética determinados por diferentes protocolosRESULTADOSLa media de edad cronológica fue 12,91 años, estatura 159,86cms y masa corporal 49,70kgs. La media de la edad esquelética determinada por TW2 es mayor que la media de los métodos TW3 y Fels, y la media de Fels SA es mayor que TW3 SA. Entre los jugadores que no tenían madurez esquelética por ninguno de los métodos (n = 72) La diferencia entre la media de Fels y TW3 SA es significativa (F = 37,50, p <0,001).CONCLUSIONESEl presente estudio examinó el acuerdo entre los protocolos concurrentes para la determinación de la edad esquelética (FELS y TW3) en una muestra de tenistas masculinos. La media de edad esquelética determinada por Fels fue mayor que TW3 SA. Entre los jugadores que no eran esqueléticos maduros por ninguno de los dos métodos la diferencia entre la media de Fels y TW3 SAs fue significativa (F = 37,50, p <0,001.Para medir las edades esqueléticas tienen un impacto en la selección, desarrollo y progresión en el talento, así como en el entrenamiento a largo plazo. El tenis juvenil competitivo necesita velocidad, agilidad y capacidad aeróbica para competir (Kovacs, 2007).por
