The PhenoMol computational model analyzes biomarkers of cellular activity to help predict an individual’s physical fitness level. The model could advance future studies to improve fitness training and speed injury or disease recovery. Patterns of molecular activity in the blood may hold clues not only to how fit someone is, but also to the biological processes that support physical performance. Researchers at MIT, GE HealthCare, and the U.S. Military Academy at West Point have dev... [7786 chars]
