Biological ageing is one of the biggest risk factors for a range of diseases, including cancers, neurodegenerative disease, and heart disease. Mitochondrial dysfunction is associated with both ageing and diseases of ageing. As exercise is increasingly being viewed as a potential anti-ageing therapy, we sought to assess the impact of exercise on the fitness and lifespan of D. melanogaster[1]. In addition, we assessed the exercise-induced changes to mitochondrial physiology through high-resolution respirometry and label-free mass spectrometry. Exercise in late life extends the lifespan of male and female D. melanogaster compared with those exercised throughout their entire lifetime. Exercise also increases Complex-II-linked respiration and upregulates the expression of proteins from the electron transfer Complexes I, III, IV.
