Video: Testing the science behind Kenzen's Echo H2 Sensor

A few days ago I came across this Indiegogo crowdfunding campaign for a new wearable device called the Echo H2 Sensor which claims it can detect your glucose levels, hydration status, and lactate levels in real-time during exercise by analyzing your sweat.  I set out to do some research on whether there's any science behind their claims.

John J Davis, PhD

I have been coaching runners and writing about training and injuries for over ten years. I've helped total novices, NXN-qualifying high schoolers, elite-field competitors at major marathons, and runners everywhere in between. I have a Ph.D. in Human Performance, and I do scientific research focused on the biomechanics of overuse injuries in runners. I published my first book, Modern Training and Physiology for Middle and Long-Distance Runners, in 2013.
