    El objetivo de este estudio es observar las diferencias entre atletas cadetes de Taekwondo de diferentes niveles competitivos en t茅rminos antropom茅tricos, de potencia muscular, flexibilidad y velocidad de reacci贸n. Veinte atletas varones fueron analizados, divididos en dos grupos: medallistas nacionales y no medallistas nacionales. Para cada atleta se tomaron datos antropom茅tricos, de velocidad de reacci贸n, potencia muscular y rango de movimiento articular de la articulaci贸n coxofemoral. Los atletas medallistas mostraron valores significativamente menores en altura, envergadura, tiempo de reacci贸n 贸culo-podal, y tiempo de reacci贸n 贸culo-manual con mano no dominante; y valores mayores para longitud de piernas, flexi贸n pasiva de cadera, y abducci贸n de cadera tanto activa como pasiva. Las leves diferencias observadas entre grupos en potencia muscular, grasa corporal y flexi贸n activa de cadera no concuerdan con estudios previos. Conocer est谩 informaci贸n podr铆a ser de inter茅s para los entrenadores para llevar a cabo programas de detecci贸n de talentosThe aim of this study was to determine the differences between Taekwondo cadet athletes belonging to different competition levels in terms of anthropometry, legs power, flexibility and reaction time. Twenty male athletes were analysed, divided in two groups: national medallist and non-national medallist. Data of every athlete鈥檚 anthropometric measurements, reaction speed ability, leg power and hip ROM (range of movement) were taken. Medallist athletes showed significantly lower values for height, arm span, foot reaction time (dominant and non-dominant) and non-dominant hand reaction time; and higher values for leg length, passive hip flexion, active hip abduction and passive hip abduction in ROM tests. Slight differences observed between medallists and non-medallists in leg power (CMJ), body fat (危 skinfolds) and active hip flexion do not agree with previous studies. Knowing this information could be interesting for coaches in order to carry out talent detection program
