Effectiveness of multicomponent training on physical performance in older adults: A systematic review and meta-analysis

Abstract

Multicomponent training (MCT) is characterized by the combination of at least 3 types of training. The purpose of this meta-analysis was to assess the effectiveness of MCT programs for improving physical performance in healthy older adults. A systematic review and meta-analysis of randomized control trials (RCTs) was conducted. The systematic search was performed in the Web of Sciences, PubMed (MEDLINE), and Cochrane Library databases. Articles were included if participants were healthy and 65 years or older, and the control group did not perform any type of training. Studies were excluded if the interventions lasted less than 8 weeks. PEDro scale and Risk of Bias tool (RoB) were used in order to assess the quality of the articles. The search strategy found a total of 388 studies. After inclusion and exclusion criteria, 19 studies were included for the qualitative analysis. Finally, 13 articles were included in the meta-analysis, with a total of 808 healthy older adults analyzed. The main results of the meta-analysis showed that MCT improves physical performance significantly more than no training (SMD: 0.78; 95% CI: 0.55, 1.00; Z = 6.84, p < 0.01; I2 = 54%). In addition, the MCT also seems to significantly increase in upper and lower limb strength, walking speed and aerobic capacity. MCT improves general functionality, strength in upper and lower extremities, walking speed and aerobic capacity. Implementation of MCT programs should be encouraged as an effective strategy in the prevention of adverse conditions in the older adult.
