Abstract: BACKGROUND: Currently, the research on the fatigue elimination effect of hyperbaric oxygen therapy mainly involves two forms: single-session intervention and periodic multiple intervention, with the application research of single therapy being the main focus. However, the effectiveness of single-session hyperbaric oxygen therapy on exercise-induced fatigue remains controversial, affecting its application in sports training. 
OBJECTIVE: To summarize the intervention effect of a single hyperbaric oxygen therapy on exercise-induced fatigue from two aspects: the commonly used biochemical monitoring indicators and physiological monitoring indicators for exercise-induced fatigue, and proposes corresponding application strategies based on the current status of application research and training practice. 
METHODS: Literature searches were conducted in both Chinese (e.g., CNKI and WanFang) and English (e.g., PubMed) databases using the keyword combinations “hyperbaric oxygenation, micro-barometric oxygen, oxygen therapy, micro-hyperbaric oxygen” and “exercise fatigue, high intensity exercise, heart rate, heart rate variability, rating of perceived exertion, blood urea, creatine kinase, testosterone, cortisol, white blood cell, hemoglobin,” respectively. The search period spanned from January 2001 to June 2025. A total of 62 papers were ultimately for review and analysis. 
RESULTS AND CONCLUSION: (1) Single-dose hyperbaric oxygen intervention can promote the elimination of exercise fatigue, but the intervention effect on commonly used physiological monitoring indexes is better than that of biochemical indexes, in which the type of fatigue and the degree of fatigue (the variability of fatigue-inducing protocols), the insufficient dosage of hyperbaric oxygen, and the metabolic characteristics of the biochemical indexes in the body may be the main factors causing this problem. (2) In view of the current research situation, it is suggested that the follow-up research should be conducted in the following directions: “Comprehensively compare the advantages and disadvantages of different hyperbaric modes, deeply compare the intervention effects of different hyperbaric intervention times on exercise fatigue, clarify the intervention effects of single hyperbaric oxygen therapy during non-acute exercise fatigue, and establish a comprehensive evaluation index system for the intervention effects of hyperbaric oxygen.”
