Resistance training in older adults at the cellular level

Published on January 17, 2023

Aging and related diseases are associated with alterations in oxidative status and low-grade inflammation, as well as a decreased endoplasmic reticulum (ER) unfolded protein response (UPR). UPR is a functional mechanism by which cells attempt to protect themselves against ER stress. Researchers analyzed these proteins in peripheral blood mononuclear cells of elderly subjects and used computer simulation to predict the key proteins associated with these biomolecules underlying physiological adaptations to exercise. They collected blood samples about five to six days before and after the training period and analyzed various oxidative stress biomarkers in peripheral blood mononuclear cells. The study takes research one step further in helping to elucidate the benefits of exercise in this population.
