Circulating protein levels may serve as a biomarker for cardiorespiratory fitness, an important but previously hard-to-measure component of overall health, according to a study published in Nature Medicine.
Although cardiorespiratory function can provide a snapshot of holistic health, no standardized method currently exists to measure cardiorespiratory fitness, said Ravi Kalhan, MD, MS, professor of Medicine in the Division of Pulmonary and Critical Care, of Preventive Medicine in the Division of Epidemiology, and a co-author of the study.
“As a doctor seeing patients, I can’t measure the fitness of a patient sitting in front of me,” said Kalhan, also the Louis A. Simpson Professor of Pulmonary Medicine. “We could do various fancy tests, but that’s a big undertaking, and not every patient can walk on a treadmill, such as those who are older or have chronic lung disease.”
Cardiorespiratory fitness impacts almost every system in the body, from the metabolism to the brain, Kalhan said, so developing a way to measure it would allow physicians to accurately assess general health.
