Physical activity benefits muscles through mitochondrial processes, as evidenced by nematode worm experiments conducted at the University of São Paulo’s Biomedical Sciences Institute (ICB-USP).
Regular exercise can guarantee the quality of life and longevity, specialists agree. However, exactly how exercise influences the functioning of muscle cells is poorly understood.
The new study helps understand at the cellular level how physical activity contributes to fitness during the aging process.
The study was supported by FAPESP. An article describing it is published in the Proceedings of the National Academy of Sciences (PNAS).
According to the authors, the answer lies in mitochondria, membrane-bound organelles that generate most of the chemical energy needed to power the cell’s biochemical reactions.
