A new wearable by Sweetzpot seeks to measure breathing and heart rate using a chest band called FLOW that eliminates the need for a clunky face mask and helps athletes find their stamina sweet spot.
The device, which can be used inside or outdoors, offers athletes metrics about the air flowing into their body by litres per minute, providing users data about the breathing patterns they can then tweak to maximize athletic performance. Ventilation can spike to as high as 160 liters/min during high intensity workouts from six to eight liters/min at rest, according to the data provided by the company.
