Multi-Mode Acceleration-Based Athleticism Measurement System

A non-transitory computer readable medium storing instructions that, when executed by a processor of an apparatus, cause the processor of the apparatus to:

• track movement of a sensor, wherein data from the movement of the sensor is recognized as a user's physical activity, and wherein the data includes an average contact time for a foot of the user;
• compare the data to a predetermined performance criterion;
• and
• electronically providing a guide for improving running movement efficiency of the user based on the comparison of the physical activity data to the predetermined performance criterion.

An apparatus comprising:

• a user input device;
• a sensor;
• a processor;
• and
• memory storing computer readable instructions that, when executed by the processor, cause the processor to at least:
• track movement of the sensor, wherein data from the movement of the sensor is recognized as a user's physical activity, and wherein the data includes an average contact time for a foot of the user;
• electronically transmit a guide for improving a running movement efficiency of the user, wherein the guide for improving running movement efficiency is calculated by analyzing acceleration data associated with at least one of the user's shoes to characterize running stride information.
