Abstract
Objective
To investigate the effects of different movement velocities during progressive resistance training (PRT) on bone mineral density (BMD) in older adults, with an emphasis on program design and training principles.
Methods
Seven databases were comprehensively searched to identify studies investigating the effect of PRT at different movement velocities on BMD. The primary outcome was BMD at fracture-relevant sites measured by dual-energy X-ray absorptiometry (DXA). Meta-analysis of within-group changes was conducted using a random-effects model.
Results
Of 1830 screened records, 9 studies met the inclusion criteria. No statistical comparison was possible regarding movement velocity. However, the findings suggest benefits of incorporating high-velocity movements. The analysis revealed that moderate-velocity programs frequently failed to prevent bone loss. In terms of program design, significant benefits of variation in PRT programs were observed. Moreover, the interventions demonstrated substantial interindividual variability in efficacy.
Conclusion
High-velocity PRT effectively enhanced BMD when overarching training principles were met. Nevertheless, further research is required to confirm the superior efficacy of high-velocity training. Moreover, individualization is essential since responses to programs vary, prompting questions about underlying differences. Considering that osteoporosis involves defective mechanotransduction, factors beyond established confounders may influence the intervention's efficacy.
期刊介绍:
Archives of Gerontology and Geriatrics provides a medium for the publication of papers from the fields of experimental gerontology and clinical and social geriatrics. The principal aim of the journal is to facilitate the exchange of information between specialists in these three fields of gerontological research. Experimental papers dealing with the basic mechanisms of aging at molecular, cellular, tissue or organ levels will be published.
Clinical papers will be accepted if they provide sufficiently new information or are of fundamental importance for the knowledge of human aging. Purely descriptive clinical papers will be accepted only if the results permit further interpretation. Papers dealing with anti-aging pharmacological preparations in humans are welcome. Papers on the social aspects of geriatrics will be accepted if they are of general interest regarding the epidemiology of aging and the efficiency and working methods of the social organizations for the health care of the elderly.
