Hydrogen peroxide as a signal for skeletal muscle adaptations to exercise: What do concentrations tell us about potential mechanisms?

Hydrogen peroxide plays a crucial role in cell signaling, triggering positive changes in muscle strength and endurance during exercise.  

Hydrogen peroxide helps send signals for various processes, such as making our muscles stronger and more efficient during exercise. When we exercise, our muscles undergo positive changes like increased strength and endurance that are triggered by reactive oxygen species (ROS) i.e., hydrogen peroxide. At first, it was believed ROS were harmful, but now we know they play a vital role in signaling and regulating processes within our bodies. This article suggests that hydrogen peroxide, an ROS, is essential for the positive adaptations in our muscles.
