Skin autofluorescence is associated with arterial stiffness and insulin level in endurance runners and healthy controls - Effects of aging and endurance exercise

To our knowledge, these are the first data to show that skin autofluorescence (SAF) is linked to human arterial stiffness and insulin resistance in well-trained elderly and young men as well as sedentary controls. SAF may in the future be a helpful tool to predict vascular and metabolic dysfunction (early signs of aging and pathology). Surprisingly, endurance running only had modest effects on cardiovascular function compared to lean healthy controls.
