As part of Valencell’s ongoing commitment to creating true, smart, and fun precision biometrics, the company is continuously validating our technology through internal and external clinical trials.  A recent landmark tied to those principles was the presentation of clinical trials of the PerformTek (formerly V-LINC) continuous heart rate monitoring.  At the 59^th Annual Meeting of the American College of Sports Medicine, Meir Magal, Ph.D., FACSM, presented the findings of his independent study on the accuracy of Valencell's technology. The study confirmed Valencell earbud sensors were a valid and reliable instrument for continuous measurement of heart rate during exercise. The sensors were strongly correlated to the heart rate measure obtained from a twelve lead electrocardiogram and preformed reliably on a day-to-day basis.  

Dr. Magal utilized a dynamic undulating treadmill protocol that ranged from low to vigorous exercise intensity (from walking to 7 mph) in an effort to test the robustness of the sensors.    Our team was excited to attend the presentation and obtain details of the research.  The following summaries are from the presentation itself including the first figure that contains 7080 data points recorded in the study:

Stay tuned for data reports from our ongoing internal validation including cycling, running at high speeds, high intensity workouts, and even our fun interoffice lunch-time cycling session.
