3. Introduction into Mobile Coaching PART 1

4. » The technological progress in computer science involves the development of new coaching and training methods: Background aspects Part: 1 2 3 4 5 Computer-aided training Feedback systems Mobile Coaching Feedback is crucial Integration of mobile communication and information technologies into the training process

5. Mobile Coaching » Goal: to allow mobile and handy training support for sport-related people, primarily by the use of modern technologies: » Mobile device › PDA, smartphone, MID etc. » Wireless communication › Sensor network (e.g. ANT) › Internet connection (WiFi, UMTS etc.) Part: 1 2 3 4 5

6. Aims & objects » Generic Mobile Coaching system » Mobilization (by handheld computers) » Location independency » Prompt online (expert) feedback during the training Part: 1 2 3 4 5 Athlete with mobile device I N T E R N E T Remote feedback (expert, PC)

7. A server-based Mobile Coaching approach PART 2

8. System architecture Part: 1 2 3 4 5 Athlete-Client Expert-Client

9. Components » Sensor system › Heart rate & force sensor, accelerometer etc. attached to the athlete/equipment » Mobile device application ( A thlete-client) › PDA/MID for receiving parameter values & synchronization with server » Server › Administration, organization of the synchronized data » Server-based web applications ( E xpert-client) › Analysis & feedback to A-client from a distant place Part: 1 2 3 4 5

10. Scenario - cycling Part: 1 2 3 4 5 » Based on measured parameters, the cyclist is provided with feedback information during the training Athlete Expert

11. Development & implementation results PART 3

12. Development (tools) Part: 1 2 3 4 5 » A-Client › IBM Lotus Expeditor Client » E-Client › PHP & JpGraph » Server › IBM Lotus Expeditor Server Description Tool Bundle Developer Kit IBM Lotus Expeditor Toolkit Development Environment Eclipse 3.2 IDE Supporter Client Runtimes j9/jclDesktop, j9/jclDevice Programming Language Java Database Development IBM DB2 Components IBM DB2 Server (+ DB2 Everyplace Synch) IBM HTTP Server IBM WebSphere Server PHP & JpGraph

13. Implementation results – heart rate (MID) Part: 1 2 3 4 5 » Feedback returned to mobile device via web application on server CALM DOWN CALM DOWN

14. Visualization example - forces in rowing (PDA) Part: 1 2 3 4 5 » Vizualization tool for experts, illustrating 1 stroke in rowing

15. Discussion PART 4

16. Crucial points » Mobilization factor › Web-enabled mobile device › Location-independent › Expeditious feedback » Monitoring by experts › Analyzing the athlete‘s performances › Returning feedback from distant places Part: 1 2 3 4 5 » User scope › Sportsmen › Coaches › Experts » Applied sports (generic) › Running › Cycling › Fitness › Rowing Scope of use

18. Conclusions PART 5

19. Conclusions A server-based Mobile Coaching approach was presented, which assists athletes and coaches in their workout process by the integration of: › wireless sensors applied to the bodies/equipment of the athletes › mobile communication technologies › server-based feeback methods offering a mobile feedback support between athletes and remotely located experts.
