We can all recognise that feeling of muscle fatigue after taking a brisk walk, cycling, running or playing football. Our ability to engage in physical activity for long periods of time is thanks to ...

This partial figure from the paper illustrates the steps taken to compare the mitochondria of young and old mice. First, thin tissue slices were imaged with an advanced imaging method called serial ...

Researchers from the University of Southern Denmark investigated how eight weeks of high-intensity interval training affect the structure of mitochondria—the parts of muscle cells that produce energy.

Mitochondria are the powerhouses in our cells, producing the energy for all vital processes. Using cryo-electron tomography, researchers at the University of Basel, Switzerland, have now gained ...

Eight weeks of HIIT increases both the number and efficiency of muscle mitochondria by expanding their energy-producing inner membranes.
