Phosphagen refers to a group of molecules in our bodies that store and release energy during activities like sprinting or weightlifting. They help provide quick bursts of energy for intense physical efforts. Full definition
When we are utilizing power and training power, we are making use of phosphagen system. (christianbosse.com)
Interestingly, there is some rising evidence pointing to a link between aspirin consumption and storage of phosphagens in the muscle tissue. (strengthsensei.com)
Lastly, for very short bursts of energy, such as a 10 - second sprint, muscles can rely on another type of anaerobic system: they use up energy - storing compounds, called phosphagens, in muscular tissues. (sciencemag.org)
