Sarcopenia is associated with morbidities such as risk of falls, loss of autonomy, hospitalization and death in seniors due to reduced lean mass and increased body fat. Resistance training is a good option for the treatment of of this elderly patients, however, access to gymnasiums is restricted especially to the most needy populations that only rely on the services offered for primary health care. functional exercises that can be performed at home can be a good alternative to maintain mobility and functional capacity, however it is not known if this kind of exercises can change body composition of sarcopenic elderly. The objective of this study was to verify the effectiveness of a physical exercise protocol in the body composition and functional capacityof sarcopenic elderly in a central region of Brazil.
Its a quasi-experimental study performed with community-dwelling women (70-80 years) diagnosed with sarcopenia according to the EWGSOP divided into three groups: Group 1: functional exercises (HOPE); Group 2: HOPE and pre and post workout snack and group 3: health education. Groups 1 and 2 were performed twice weekly for 12 weeks and group 3 once weekly for 12 weeks.
HOPE is a program of 19 functional exercises developed by Clegg et al (2010) whose progression is based on the performance of the time up and go test, indicated for frailty elders.
Body composition: we used the octopolar electric bioimpedance (BIA) InBody 570; its following the protocol of calibration and data capture according to the manufacturers instructions, referring to fat free mass, skeletal muscle mass,% fat and hydration before and after the intervention.
Functional capacity: the short physical performancy battery (SPPB) was performed, as well as handgrip and gait speed tests.
The study was approved by the ethics committee under opinion 1,128,355/2015.
30 women completed the study. When comparing the pre and post-intervention body composition by means of BIA no statistical differences were observed within and between groups, showing that the protocol was not effective in the subjects body composition.
The HOPE protocol seems to be a good training strategy with regard to the reversal of the state of low functional capacity, however it is insufficient to generate changes in the morphology of the body composition of sarcopenic elderly. When comparing pre and post intervention results in functional capacity, there was a significant improvement in intragroup parameters of handrip and gait speed group 2 in relation to group 3, as well as in SPPB. Group 1 also presented significant improvements when compared to group 3 in handgrip and SPPB. No observed intragroup differences were observed.
