Wearable devices have become a common accessory for those participating in sports and fitness activities, and have contributed to the increase in popularity of active pursuits. Such devices are able to estimate external parameters such as number of steps, calories consumed, distance travelled, and heart rate. However, the available devices are not able to measure true biometrics that can give personalised and quantifiable indications of performance, effect of dietary intake, response to exercise, effect of rest periods and data relevant to the prevention of injuries. Every human body is unique, breaks down food differently, and has varying metabolic needs, energy expenditure, response to exercise and other related stimuli. In order to solve the present inactivity crisis (both in Europe and worldwide) without a subsequent proliferation of sports injuries, it is crucial to provide tools that enable users to truly engage with their personal training plans and take control of their health and fitness. The overall objectives for Caura are to introduce Smart Tracker to the market. Smart Tracker is an innovative, platform technology capable of unlocking the body's molecular signature to provide a true picture of performance in real-time. The platform has been integrated into a revolutionary wearable device that can measure a range of health-related parameters and provide personalised recommendations for ongoing improvement.
