About the Journal

Mission

The mission of the Journal of Exercise and Nutrition (JEN) is to provide open-access, high-quality, and innovative research that advances understanding of exercise, nutrition, and dietary supplementation. JEN is committed to translating scientific discovery into meaningful, evidence-based applications that improve health, performance, and measurable outcomes across clinical, athletic, community, and real-world settings. Published by Pinnacle Science, JEN is part of a growing platform that generated over 132,000 abstract views and more than 67,000 downloads in 2025 alone.

Peer-Review Process

The journal and its editorial board are dedicated to providing authors with an efficient and streamlined peer review process, ensuring timely feedback while maintaining the highest standards of quality and integrity.

Aims and Scope

JEN is dedicated to advancing high-quality basic, translational, and applied research at the intersection of exercise science, nutrition, human performance, and health. The journal welcomes innovative investigations that integrate physiological, biochemical, behavioral, and clinical perspectives to better understand how exercise and nutritional strategies influence health, performance, recovery, and disease prevention across the lifespan.

JEN publishes concise, impactful scholarship including original research, research briefs, systematic and narrative reviews, clinical case reports, and applied performance studies. Submissions should demonstrate methodological rigor, clear statistical reporting, and meaningful practical applications for researchers, clinicians, sport scientists, dietitians, strength and conditioning professionals, and allied health practitioners.
