Introduccion. En los adultos mayores existe una disminucion de la fuerza muscular que es mas significativa en mujeres que en los hombres. Objetivo. Conocer los cambios que en fuerza explosiva puedan generarse, posterior a la intervencion con un programa de entrenamiento en fuerza maxima. Materiales y Metodos. Estudio cuasiexperimental con diseno pre-prueba y post-prueba, en una cohorte de adultas mayores quienes durante 12 semanas, recibieron entrenamiento en fuerza maxima, entre un 44% y un 54% de su RM. Los criterios de inclusion fueron, ser adultas mayores (≥60 anos), con indice de masa corporal (IMC: 19-30 kg/m 2 ), que asistieran al programa de actividad fisica para el adulto mayor, de la Universidad Santo Tomas en Bogota (Colombia). Resultados. Se encontraron cambios en la fuerza explosiva con el entrenamiento, pero no son estadisticamente significativos, pero en cambio se encontraron cambios en la antropometria que si tienen una correlacion significativa con la fuerza explosiva medida a traves de SQJ. Conclusiones. Los resultados evidencian que es posible generar cambios en porcentajes de tejido graso a traves de entrenamiento en fuerza y no exclusivamente en resistencia aerobica y es necesario aumentar la muestra poblacional para reconocer con mayor claridad los cambios que se puedan generar en fuerza en el adulto mayor. Abstract. Introduction. In older adults there is a decrease in muscle strength that is more significant in women than in men. Objective. Assess the changes in explosive force that can be generated after an intervention with a training program on maximum force. Materials and methods. A quasi-experimental study with pre-test and post-test design, in a cohort of older adults who, during 12 weeks, received training on maximum strength, between 44% and 54% of their MRI. The inclusion criteria were to be older adults (≥60 years);to have a body mass index of 19-30 kg / m2); to attend the physical activity program for the elderly of the Santo Tomas University in Bogota (Colombia). Results. We found changes in the explosive force after the training; however, they are not statistically significant. Changes were found in anthropometry, this showing significant correlation with explosive force measured through SQJ. Conclusions. The results show that it is possible to generate changes in percentages of fat tissue through strength training and not exclusively with aerobic resistance. Also, it is necessary to increase the sample size in order to recognize with greater clarity the changes that can be generated in strength in elderly.
