SHR # 2590 :: Exercise Induces Secretion of Biomarkers Into Sweat plus Exercise Improves Children's Blood Pressure - Dr. Sira Karvinen, PhD - A new study shows that in addition to blood, endurance exercise induces changes in sweat biomolecule levels. These findings lay the groundwork for the development of future noninvasive exercise monitoring systems that utilize sweat as a biomarker source. Sweating is an important part of thermoregulation during exercise, yet the potential for sweat as a biomarker source has not been established. Currently, the key limiting steps of using sweat as a biomarker source for exercise monitoring are the low abundance of biomarkers and variation in the volume of sweat in different environments and in different people. PLUS High blood pressure and arterial stiffness is a thing today in young school-aged children. A recent study showed that a very simple exercise intervention can completely reverse this condition.
