Abstract
The alteration in nerve conduction produced by MS leads to functional displacement. Specifically, this increase produces losses of muscle mass, bone mineral density (BMD) and power as well as an increase in fat mass. In general, physical exercise has shown improvements at the functional level, however, strength training seems to show the best results for these parameters. The purpose of this study was to evaluate the effects of two power and hypertrophy training programs on BMD and potency in people with MS. Ten subjects with MS participated with a mean age of 56 years, of which eight were women and two men. The sample was divided into two groups randomly. Each group is assigned a training program randomly. BMD, power, strength and speed measurements were obtained before and after both training programs. Differences were found in the BMD variables in the hypertrophy training group (EH) and in the potency of the power training group (PE). No differences found between both groups were found for any of the other variables. Hypertrophy training reduces BMD and does not improve power, strength and speed. While power training improves potency and does not improve the body composition of this type of population.
