简要总结
This study aims to identify the mechanisms by which physical exercise can counter inflammation and improve immune function in older persons. These mechanisms will be investigated to develop exercise-based/derived strategies to improve recovery of older patients suffering from immunosenescence and/or immune suppression.
In this randomized controlled trial, the effects of resistance exercise (RE) on inflammation and chronic low-grade inflammation (CLIP) will be investigated.
The investigators expect that exercise-induced changes in immunosenescence will be reflected by changes in the various domains of interest: 1) the expression of immunosenescence-related genes in PMBC, in circulating markers of inflammation and in PMBC behaviour following LPS stimulation, 2) the proportion of circulating PMBC showing surface and/or intracellular markers for cell senescence, and 3) markers reflecting alterations at the level of the extracellular matrix.
Additionally, the investigators want to verify whether 1) resistance exercise improves inflammation and immunosenescence in skin tissue, and 2) resistance exercise improves the stress response in skin tissue after an in-vivo inflammatory challenge by saline injection.
The results of this project will allow us to provide new insights in the complex interaction between physical exercise and immunosenescence as well as to present evidence-based guidelines for exercise in elderly persons to counter CLIP
