Abstract:
Exercise-induced fatigue is closely associated with mitochondrial dysfunction, and mitophagy plays a critical role in maintaining mitochondrial homeostasis by clearing damaged mitochondria and reducing oxidative stress. This review systematically summarizes current evidence on the regulatory mechanisms of mitophagy in exercise-induced fatigue, particularly through pathways such as PINK1/Parkin, BNIP3/Nix, FUNDC1, and AMPK, and examines how natural compounds including sulforaphane, Rhodiola crenulata, ginseng, modulate these pathways to alleviate fatigue. These findings suggest the presence of mitophagy threshold in different models and highlight its potential as a therapeutic target for fatigue management. Ultimately, this review proposes novel strategies for developing natural anti-fatigue agents based on mitophagy regulation, while underscoring the need for further mechanistic studies in diverse physiological and pathological settings.

Translocation of Proteins into the Mitochondria
Sorting of outer membrane proteins:
Mitochondrial outer membrane proteins are of two types: the transmembrane, beta-barrel porins, and the membrane-anchored, alpha-helical proteins. Beta-barrel porin precursors are translocated by the TOM complex and inserted into the outer mitochondrial membrane by the SAM complex. In contrast,...
