| Abstract (English): | This study investigated the relationship between variables of the deep squat jump (DSJ) and the Abalakov jump (ABK) and the performance of the rear leg roundhouse kick in elite combat sport athletes. Twenty-seven elite taekwondo athletes (12 females) performed three attempts of each movement: DSJ and ABK (measured with Pasco® force platforms), and the roundhouse kick (analyzed with Vicon® motion capture systems). The key findings demonstrated that specific force and power metrics from the jumps are significant predictors of kicking kinematics. For the DSJ, the rate of force development (RFD) in the first 100 ms of the concentric phase (RFDcon) was a primary predictor, independently explaining 21% of the variance in linear foot velocity (p=0.009) and 30.3% in linear foot acceleration (p=0.003). Furthermore, for the non-dominant (stance) limb, takeoff peak force independently predicted angular hip acceleration (R²=0.144, p=0.029). For the ABK, the eccentric braking RFD at 100 ms (RFDecc) emerged as a strong predictor, accounting for 24% of the variance in angular hip acceleration (p=0.006). In conclusion, this study validates the DSJ and ABK as practical tools for assessing qualities critical to roundhouse kick performance. Coaches should prioritize monitoring RFDcon and stance limb strength during a DSJ, as well as the RFDecc during an ABK, to evaluate and train for improved kicking power. [ABSTRACT FROM AUTHOR] |
| Abstract (Spanish): | Este estudio investigó la relación entre variables del salto en cuclillas profundo (DSJ) y del salto Abalakov (ABK) y el rendimiento de la patada circular con la pierna trasera en atletas de deportes de combate de élite. Veintisiete atletas de élite de taekwondo (12 mujeres) realizaron tres intentos de cada movimiento: DSJ y ABK (medidos con plataformas de fuerza Pasco®), y la patada circular (analizada con sistemas de captura de movimiento Vicon®). Los hallazgos clave mostraron que las métricas específicas de fuerza y potencia de los saltos son predictores significativos de la cinemática de la patada. Para el DSJ, la tasa de desarrollo de fuerza (RFD) en los primeros 100 ms de la fase concéntrica (RFDcon) fue un predictor principal, explicando de forma independiente el 21% de la varianza en la velocidad lineal del pie (p=0.009) y el 30.3% en la aceleración lineal del pie (p=0.003). Además, para el miembro no dominante (de apoyo), el pico de fuerza en el despegue predijo de forma independiente la aceleración angular de la cadera (R²=0.144, p=0.029). Para el ABK, la RFD de frenado excéntrico a los 100 ms (RFDecc) surgió como un fuerte predictor, explicando el 24% de la varianza en la aceleración angular de la cadera (p=0.006). En conclusión, este estudio valida el DSJ y el ABK como herramientas prácticas para evaluar cualidades críticas para el rendimiento de la patada circular. Los entrenadores deberían priorizar el monitoreo de la RFDcon y la fuerza del miembro de apoyo durante un DSJ, así como la RFDecc durante un ABK, para evaluar y entrenar la mejora de la potencia de la patada.

Para o DSJ, a taxa de desenvolvimento de força (RFD) nos primeiros 100 ms da fase concêntrica (RFDcon) foi um preditor primário, explicando de forma independente 21% da variância na velocidade linear do pé (p=0.009) e 30,3% na aceleração linear do pé (p=0.003). Além disso, para o membro não dominante (de apoio), o pico de força na decolagem previu independentemente a aceleração angular do quadril (R²=0,144, p=0,029). Para o ABK, a RFD de frenagem excêntrica aos 100 ms (RFDecc) emergiu como um forte preditor, respondendo por 24% da variância na aceleração angular do quadril (p=0,006). Em conclusão, este estudo valida o DSJ e o ABK como ferramentas práticas para avaliar qualidades críticas para o desempenho do chute circular. Treinadores devem priorizar o monitoramento da RFDcon e da força do membro de apoio durante um DSJ, bem como da RFDecc durante um ABK, para avaliar e treinar a melhoria da potência do chute.
