Fuerza explosiva en adultas mayores, efectos del entrenamiento en fuerza máxima

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 (e»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 Tomás University in Bogotá (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.
