Exercise Induced Cellular Stress

Meaning

Exercise Induced Cellular Stress refers to the temporary and controlled physiological challenge imposed on cells and tissues during physical exertion, which includes the generation of reactive oxygen species (ROS), metabolic byproducts, and minor structural damage. This acute stress is a necessary catalyst for adaptation, triggering beneficial cellular signaling pathways that ultimately lead to improved fitness, resilience, and mitochondrial health. It is a hormetic effect, where a small dose of stress yields a positive long-term response.
