INTRODUCTION: There is a current belief in aviation suggesting that aerobic training may reduce G-tolerance due to potential negative impacts on arterial pressure response. Studies indicate that increasing maximal aerobic capacity ( $\dot{\text{V}}$ o₂ max) through aerobic training does not hinder G-tolerance. Moreover, sustained centrifuge training programs revealed no instances where excessive aerobic exercise compromised a trainee’s ability to complete target profiles. The purpose of this review article is to examine the current research in the hope of establishing the need for routine $\dot{\text{V}}$ o₂-max testing in air force pilot protocols.

METHODS: A systematic search of electronic databases including Google Scholar, PubMed, the Aerospace Medical Association, and Military Medicine was conducted. Keywords related to “human performance,” “Air Force fighter pilots,” “aerobic function,” and “maximal aerobic capacity” were used in various combinations. Articles addressing exercise physiology, G-tolerance, physical training, and fighter pilot maneuvers related to human performance were considered. No primary data collection involving human subjects was conducted; therefore, ethical approval was not required.

RESULTS: The $\dot{\text{V}}$ o₂-max test provides essential information regarding a pilot’s ability to handle increased G_z-load. It assists in predicting G-induced loss of consciousness by assessing anti-G straining maneuver performance and heart rate variables during increased G-load.

DISCUSSION: $\dot{\text{V}}$ o₂-max testing guides tailored exercise plans, optimizes cardiovascular health, and disproves the notion that aerobic training hampers G-tolerance. Its inclusion in air force protocols could boost readiness, reduce health risks, and refine training for fighter pilots’ safety and performance. This evidence-backed approach supports integrating $\dot{\text{V}}$ o₂-max testing for insights into fitness, risks, and tailored exercise.
