Exercise-induced fatigue is accumulated when lactic acid cannot be timely eliminated after intensive exercise, resulting in sport injuries. Traditional lactic acid removal methods are limited in timeliness, metabolic burden, and potential toxicity. To solve the thorny problems, in this study, nanomedicine was introduced for lactic acid removal. Magnesium trisilicate was coated on the surface of magnetic nanoparticles. These nanoparticles exhibited a prompt and efficient lactic acid adsorbing behavior. Moreover, they have favorable magnetic properties and good biocompatibility. The results showed that the prepared nanoparticles hold great potential in the removal of lactic acid for preventing exercise-induced fatigue.
