NOTE: Video of this presentation is not available.

This study investigates the multifaceted effects of Arginine (Arg) supplementation on energy metabolism and its subsequent impact on athletic performance. Through a rigorous systematic review and meta-analysis, the research probes into the nuanced effects of Arg supplementation across aerobic (≤VO2max) and anaerobic (>VO2max) performance spectrums. Arg distinguishes itself in sports nutrition by synthesizing Nitric Oxide (NO), promoting vasodilation, and optimizing blood flow. This process is instrumental in enhancing the delivery of oxygen and nutrients to muscles during physical exertion, a critical factor in sports performance.

The physiological mechanisms through which Arg exerts its effects are thoroughly explored in the study. These include its role in NO synthesis, pivotal for effective blood circulation and muscle oxygenation. Furthermore, Arg's involvement in muscle contraction, gas exchange, oxygen kinetics, and mitochondrial function is meticulously dissected. The study also acknowledges the role of Arg in promoting the release of growth hormones, which are integral in muscle development, fuel mobilization, and overall physical performance. Given the intricate nature of the body's response to supplements and the variation in individual physiology, the study underscores the importance of tailored Arg supplementation protocols. It recommends acute dosing of 0.15 g/kg body weight 60–90 minutes before exercise, and for sustained improvement in aerobic and anaerobic performance, a regimen of 1.5–2 g/day over 4–7 weeks and 10–12 g/day over 8 weeks, respectively.

While the results indicate Arg's potential benefits in sports nutrition, the study acknowledges the need for further research to comprehend its efficacy across diverse athletic disciplines and conditions fully. This comprehensive review lays a solid foundation for future explorations, aiming to optimize supplementation strategies and maximize the athletic performance and recovery of sports enthusiasts and professional athletes alike.
