Analysis with the LPM- System

• Triangulation

• 12 base stations

• Camerasystem (Realtime)

• Vests with transponders

What did we measure?

• Total distance on ice (m)

• Timezones (low-high intensity) (min)

• Changes of directions

• Number of sprints

• Average and maximal speed (m/s)

• Accelerations (m/s2)

• Average and maximal heartrate (bpm)

Pro LPM

• Indoor and outdoor

• Precision: ± 5cm (GPS is less precise)

• 1000Hz dynamic movements

• Telemetry (Heartrate)

• Full automatic analyse (real time)

• Direct monitoring

• Many variabels are measured (Time on Ice, accelerations, Impact, HF...)

Contra LPM

• Transponders in the vest are actually too big (Abatec is working on it)

• Installation of the portable system (1-2 days)

• Manpower
