Introducción: El método de entrenamiento de fuerza isoinercial presenta beneficios tanto en el campo del deporte y la rehabilitación. La evidencia disponible sugiere que este tipo de entrenamiento aumenta la fuerza y velocidad de las respuestas musculares. El objetivo de este estudio fue analizar los efectos de seis semanas de entrenamiento isoinercial sobre la capacidad de salto, velocidad de carrera y equilibrio postural dinámico en adultos no entrenados. Método: El diseño de este estudio fue pre-experimental. La selección de los participantes fue realizada de manera no probabilística por conveniencia. La muestra fue compuesta por 8 adultos, 4 personas de sexo femenino y 4 de sexo masculino. Se realizaron evaluaciones de evaluación de la fuerza explosiva a través del countermovement jump (CMJ), la prueba de carrera de 20 metros y la prueba de equilibrio postural dinámico Star Excursion Balance Test modificada (SEBTm). Todas las evaluaciones fueron realizadas pre y post un entrenamiento isoinercial. Resultados: Posterior al programa de entrenamiento isoinercial, la capacidad de salto aumentó un 17% en hombres y un 15% en mujeres. El tiempo de carrera disminuyó un 22% tanto en hombres como mujeres. El equilibrio postural dinámico también mostró un mejor rendimiento en las tres direcciones evaluadas en hombres y mujeres sometidos al entrenamiento isoinercial. Conclusión: El entrenamiento de fuerza con el método isoinercial parece ser una herramienta eficaz para la mejora de la capacidad de salto CMJ, velocidad de carrera y equilibrio postural dinámico en adultos saludables no entrenados.

Abstract. Introduction: The isoinertial strength training method has benefits both in the field of sports and rehabilitation. The available evidence suggests that this type of training increases the strength and velocity of muscle responses. The aim of this study was to analyze the effects of six weeks of isoinertial training on jumping ability, running speed, and dynamic postural balance in untrained adults. Method: The design of this study was pre-experimental. The selection of the participants was carried out in a non-probabilistic way for convenience. The sample was composed of 8 adults, 4 females and 4 males. Explosive strength assessment tests were performed through the countermovement jump (CMJ), the 20-meter sprint test, and the modified Star Excursion Balance Test (SEBTm) for dynamic postural balance test. All evaluations were performed before and after isoinertial training. Results: After the isoinertial training program, jump ability increased by 17% in men and 15% in women. Race time decreased by 22% in both men and women. Dynamic postural balance also showed better performance in the three directions evaluated in men and women who underwent isoinertial training. Conclusion: Strength training with the isoinertial method seems to be an effective tool for improving CMJ jump ability, running velocity and dynamic postural balance in healthy untrained adults.
