Feedback Provision on Running Technique with a Smartphone

Abstract

Most runners run by themselves and do not have access to a trainer for feedback on their running form. We thus investigated the use of a standard smartphone for feedback provision while running, which is available to almost everyone. We investigated the use of body-worn sensors for assessing running technique on the example of arm carriage. In a pre-study with 10 runners, we found that arm carriage can be monitored by a single sensor on the upper arm. We developed an Android application to monitor arm carriage in real time. The application was validated in a user study with 23 participants. Results from questionnaires revealed high user acceptance
