Aspects relate to a portable device that may be used to identify a critical intensity and an anaerobic work capacity of an individual. The device may utilize muscle oxygen sensor data, speed data, or power data. The device may utilize data from multiple exercise sessions, or may utilize data from a single exercise session. The device may additionally estimate a critical intensity from a previous race time input from a user.

Embodiments are related to systems and methods for data determining information about a subject, and more particularly to systems and methods for utilizing and distributing information related to measurements of a human subject.

A universal 6-DOF mems sensor combined with six degree of motion algorithms and human motion parameters permits individualized real time motion analysis of a user to enable accurate measurements. Data derived thereby is wirelessly sent for viewing to a Bluetooth enabled smartphone or combination smartphone and eyeglass device, such as the Google Glass headset. The sensor is worn on a wrist or ankle band or in combination with a chest mounted cardio heart rate monitor dependent on the biometric parameters measured. Typical physical exercise data gathered includes reps, sets, 10-100 yard dash times, vertical, horizontal and broad jump distances, a range of shuttle times, RAST, steps taken, distance traveled, velocity, acceleration, and calories burned. The heart rate monitor provides cardio assessment and the 6-DOF sensor measures a runner's pace and cadence data.

Methods, systems and devices are provided for motion-activated display of messages on an activity monitoring device. In one embodiment, method for presenting a message on an activity monitoring device is provided, including the following method operations: downloading a plurality of messages to the device; detecting a stationary state of the device; detecting a movement of the device from the stationary state; in response to detecting the movement from the stationary state, selecting one of a plurality of messages, and displaying the selected message on the device.

The present invention relates to a fitness device comprising a display having plurality of lights that are configured for illumination as fitness intervals are achieved by a user. The fitness device is interchangeable with plural wearable articles. This functional fitness device allows a user to track their steps while at work, shopping, an evening out, or anytime one is on the move, even when it is interchanged between different wearable articles.

In one embodiment, a method for generating a message to a friend of a user is provided, comprising: processing activity data of a first user measured by an activity monitoring device to update a value of an activity metric for the first user; identifying a change in an inequality relationship between the value of the activity metric for the first user and a value of the activity metric for a second user; in response to identifying the change in the inequality relationship, prompting the first user to generate a message to the second user.

A method of determining blood pressure measurements includes inflating a cuff, receiving an indication of pressure inside the cuff during inflation, determining a blood pressure based at least in part on the received indication, assigning a confidence level to the blood pressure, and determining whether the confidence level satisfies a threshold confidence level. Based at least on a determination that the confidence level satisfies a threshold confidence level, the method can include causing a display to display the blood pressure. Based at least on a determination that the confidence level does not satisfy a threshold confidence level, the method can include deflating the cuff, receiving an indication of pressure inside the cuff during deflation, determining another blood pressure, and causing a display to display a blood pressure.
