Resistance Training on an Outdoor Exercise Structure Improves Lower-Body Relative Strength in Older Adults.
Improving relative strength is important for maintaining functionality with age, and outdoor exercise structures could be useful to facilitate this. A total of 29 adults aged 65+ participated in a non-randomized crossover study with a 6-week control followed by a 6-week resistance training intervention on an outdoor exercise structure (3x/week). Relative strength (predicted maximal leg press/lower body lean mass [Dual-energy X-ray Absorptiometry]) and physical function variables were measured at baseline, post-control, and post-intervention. Represented as median (25th-75th), lower body relative strength improved from 7.91 (7.01-9.35) post-control to 8.50 (7.99-9.72) post-intervention (p = .002) in study completers (n = 17). Maximum leg press (p = .002), 30-second chair stand (p< .001), one-leg stance (p = .011), and maximum chest press (p = .009) also improved significantly during the intervention. There were no significant changes in aerobic activity, grip strength, lean mass, or muscle power. This study demonstrates that there could be potential relative strength benefits associated with the use of outdoor exercise structures in older adults.
期刊介绍:
Gerontology and Geriatric Medicine (GGM) is an interdisciplinary, peer-reviewed open access journal where scholars from a variety of disciplines present their work focusing on the psychological, behavioral, social, and biological aspects of aging, and public health services and research related to aging. The journal addresses a wide variety of topics related to health services research in gerontology and geriatrics. GGM seeks to be one of the world’s premier Open Access outlets for gerontological academic research. As such, GGM does not limit content due to page budgets or thematic significance. Papers will be subjected to rigorous peer review but will be selected solely on the basis of whether the research is sound and deserves publication. By virtue of not restricting papers to a narrow discipline, GGM facilitates the discovery of the connections between papers.
