Relationship Between Mechanical Effectiveness in Sprint Running and Force-Velocity Characteristics of a Countermovement Jump in Australian Rules Football Athletes

Abstract: Morris, CG, Weber, JA, and Netto, KJ. Relationship between mechanical effectiveness in sprint running and force-velocity characteristics of a countermovement jump in Australian rules football athletes. J Strength Cond Res 36(3): e59-e65, 2022-This study evaluated the mechanical determinants of 40-m sprint performance in elite Australian Rules Football (ARF) athletes and identified variables of countermovement jumps (CMJs) that related to the sprint. Fourteen elite male ARF athletes (age 5 22.7 6 3.6 years; hei… Show more

“…The strength and power values of athletes are critical indicators of sprinting performance, which, at the same time, is the base of RSA [ 16 ]. One of the best indicators of lower limb neuromuscular fatigue is CMJ performance, which has been related to sprint ability [ 17 , 18 ] and has been employed within the Bosco Index to identify the force−velocity characteristics of athletes [ 19 , 20 ]. CMJ performance has been used as a tool to individualize training loads during sprinting sessions, providing information about the mechanical and physiological response of athletes, instead of employing a standard fixed number of sprints for all players [ 21 ].…”

“…En tanto, los niveles de fuerza pico relativos al CMJ se asociaron significativamente con la cinética de sprint (potencia y fuerza horizontal) y tiempos de sprint de 5-20m (r=-.589 a r=-.630) y la altura del salto y el tiempo concéntrico en el CMJ se correlacionaron significativamente con el tiempo de sprint a 20m (r=-.550 y r=-.546) respectivamente (Morris et al, 2020). Estas relaciones son próximas a las obtenidas en este estudio al compararla con la velocidad (10-30 m) a pesar de ser atletas adultos, estos sugiere que los resultados obtenidos pueden deberse a la cantidad de horas destinadas a mejorar la condición física de los jugadores jóvenes en el proceso de formación (Metaxas et al, 2019).…”

“…Finalmente hay que destacar que la literatura propone que los métodos de entrenamiento enfocados en la pliometría (vertical u horizontal) puede producir mejoras en el salto vertical, agilidad y velocidad (Manouras et al, 2016), así como los estudios enfocados en la potencia máxima relativa (Morris et al, 2020) y a los entrenamientos de fuerza explosiva (Hammami et al, 2015). Sin embargo es importante señalar que debe existir un foco específico en mejorar la potencia pico relativa y en entornos de tiempo limitado para los deportes colectivos (Morris et al, 2020).…”

“…Firstly, as shown by several studies, muscular power is a strong predictor for explosive type athletic performance. [9][10][11] It is unknown if a reduction in the squat jump (SJ)-FV IMB without changes in P max will be advantageous for other relevant performance measures such as countermovement jump (CMJ) and sprinting performance. A shift in the FV-profile, without a concomitant increase in P max , implies that power has decreased either at high or low velocities.…”
