Senescence of human skeletal muscle impairs the local inflammatory cytokine response to acute eccentric exercise.

Abstract

The impact of aging on the cytokine response of human skeletal muscle to exercise-induced injury remains poorly understood. We enrolled physically active, young (23-35 years old, n=15) and old (66-78 years old, n=15) men to perform 45 min of downhill running (16% descent) at 75% VO2max. Biopsies of vastus lateralis were obtained 24 h before and 72 h after… (More)
