Resumen
The 2021 study by Martínez-García et al. investigated how two different pre-activation methods—Variable Intra-Repetition Resistance (VIR-R) and Isometry (ISO)—affected the throwing velocity of female handball players. While group-level significance was not reached, a high percentage of individual players (86–93%) saw improvements in throwing velocity after the protocols.
Los hallazgos enfatizan la importancia de las estrategias de entrenamiento individualizadas. Si bien los resultados grupales fueron mixtos, la alta tasa de éxito individual sugiere que los entrenadores deben probar estos métodos de preactivación caso por caso.
