SUMMARY
Skeletal muscle mitochondria produce 50%-80% more H2O2 in older mice (28-29 months) than in younger mice (6-8 months), and moreover, muscle fibers from older mice have fewer copies of mtDNA than younger mice (Harper et_al, 2021; Harper et_al, 2021). Endurance training in the elderly improves mtDNA integrity, mitochondrial density, SDH enzyme activity, ETC activity (such as complexes I, II, III, IV, and V . . .
