In this episode of Day Adder, Vic breaks down four breakthrough studies that reveal how exercise acts like a drug, changing the molecular signature in your blood—and why everyone responds differently.You’ll learn:Top 6 Proteins that predict healthspan and lifespan. C5a – A key protein in the body’s immune system. Higher levels are linked to chronic inflammation and a greater risk of disease.AGER – This receptor is involved in oxidative stress and vascular damage. Elevated AGER is often seen in people with poor cardiovascular health.RGMB – A molecule tied to blood vessel development and repair. It supports healthy circulation and may reflect how well your body adapts to exercise.CDNF – A neuroprotective protein. It helps protect brain cells during stress and may play a role in long-term cognitive health.LSAMP – Associated with nerve and muscle tissue maintenance. It may reflect the integrity of muscle and neural networks.TNR – A structural protein involved in tissue integrity and repair, especially in muscle and connective tissue.How to find your personal dose of exercise for maximal benefitWhy it’s possible to improve your blood markers without major fitness gains📚 Cited Studies & Authors (full reference text, no need to click)1. A Plasma Proteomics Signature of Cardiorespiratory Fitness and Its Association with Future Mortality and MorbidityPublished: Nature Medicine, 2024Summary: Researchers analyzed 4,792 proteins in 20 population cohorts to discover a blood-based signature that predicts long-term health outcomes. Six proteins—CFA, AGER, RGMB, CDNF, LSAMP, and TNR—were closely associated with cardiorespiratory fitness and future disease risk.Authors:Andrew S.

Plasma Proteomic Signature of BMI Reveals Heterogeneous Cardiometabolic Risk Profiles Within and Across Standard BMI ClassificationsPublished: Nature Medicine, 2023Summary: This study challenges the use of BMI as a health marker. It shows that two individuals with the same BMI can have vastly different cardiometabolic risk profiles, depending on their blood protein expression.Authors:Keoni Jacobs, Eric Leszczynski, Jacob Barber, Prashant Rao, Michael E.

Plasma Proteomic Changes in Response to Exercise Training Are Associated With Cardiorespiratory Fitness AdaptationPublished: JCI InsightSummary: Over 600 adults completed a 20-week exercise intervention. The study found that even if VO2 max didn’t improve dramatically, blood proteins consistently shifted in ways that supported better health.Authors:Jeremy Robbins, Prashant Rao, Shu-Ling Dun, Michelle J.

Familial Aggregation of VO₂max Response to Exercise Training — The HERITAGE Family StudyPublished: Medicine & Science in Sports & Exercise, 1999Summary: This foundational study revealed that people respond differently to the same workout—and that genetics play a major role in determining how much benefit (like VO2 max increases) someone gets from exercise.Authors:Claude Bouchard, Ping An, Trevor J.
