Comparison of High-Intensity Resistance and Power Training Programs in Pre-Frail and Frail Older Adults

Abstract

Abstract Aims: The purpose of this study was to determine if high-intensity resistance training or power training is more effective in improving strength and functional outcomes in pre-frail and frail older adults. Methods: Participants underwent a 10-week intervention, two times per week, performing either high-intensity resistance or power training programs. Strength and functional outcome measurements were performed pre and post-intervention, with statistical analyses completed to compare the relative impact of the two interventions. Results: High-intensity resistance training outperformed power training in 4/14 dependent variables; including one repetition maximum strength of three muscle groups, and 30 second sit to stand performance. Power training did not result in statistically greater change relative to high-intensity resistance training in any outcomes measured. Conclusions: Further research comparing the two training methods is necessary to determine which intervention is more effective in impacting frailty, and its associated impairments, in older adults.
