With approximately 60% of adults having wearable devices to track fitness and training, this presentation will discuss how data typically obtained with those devices can measure both internal and external loads to subsequently create a training load score during training and rehabilitation sessions. By monitoring acute and chronic training stress loads, risk of injury can be decreased in both individual and team sport athletes. Hardware and software for managing data will be discussed as will other data that may be of benefit in rehabilitation programs such as right left balance, ground contact time, heart rate variability and muscle oxygen saturation.
