1. A computer-based method for identifying risk during physical activities comprising:
- locating a wearable first device at a first location on a wearer;
location a wearable second device at a second location on the wearer;
receiving a first signal from the wearable first device generated from dynamic activity of the first device over time;
receiving a second signal from the wearable second device generated from dynamic activity of the second device over time;
identifying, from the first signal or the second signal, an initiation time for a physical activity performed by the wearer of the first device and the second device;
excerpting a first signal segment from the first signal for a time period following the initiation time for the physical activity;
excerpting a second signal segment from the second signal for the time period following the initiation time for the physical activity;
determining a conclusion time for the physical activity;
calculating measurements of the wearer for the time period during the physical activity from the first signal segment and the second signal segment; and
calculating a risk metric from a risk model based on the measurements of the wearer for the time period during the physical activity, the risk metric being indicative of high risk physical activity,wherein the initiation time and the conclusion time are each determined based on sensor data from the first device or the second device; and
wherein the initiation time for the physical activity is determined prior to the conclusion time for the physical activity.
