CHALLENGE

To analyze athlete movements & techniques in real conditions

To support its research activities, Rouen’s University in France needed to find a solution to measure inter-segmentary angles on athletes in real conditions of practice. The university was looking for a simple and small system enabling specific data collection in the usual practice space without altering the athlete performance.

Wireless, miniaturized and energy self-sufficient, HIKOB wireless data acquisition systems are mobile and re-usable for multiple sporting activities. They enable data collection in real conditions analyzing more representative cycles of the entire activity than traditionnal multicameras systems.

The University deploy HIKOB system and set it up on athletes body in various sport disciplines: ice hockey, trail running, swimming & climbing. They thus analyzed movements fluidity of a climber, measured variations in acceleration of a trail runner carrying a bag on his back, studied swimmers coordination in crawl and observed regardless gesture frequency, skating cycle phases and lower limbs organization in ice hockey.

« HIKOB provides inertial measurement units individually equipped with a data logger and their own storage space. They provide a very high battery life and automatically synchronize themselves to communicate with each other. It is a very light and miniaturized system. »

« The HIKOB team was highly receptive and understanding for carrying out the project. We are very interested to continue the collaboration with HIKOB on systems evolution in order to adapt it more preci- sely to our application field. »

SOLUTIONS

Synchronized network of wireless inertial measurements units

  • +12 HIKOB FOX: inertial measurement units placed on the athlete
  • Each HIKOB FOX nodes includes 9° of freedom inertial measurement unit:
    – 3D accelerometer
    – 3D gyrometer
    – 3D magnetometer
  • 1 synchronization gateway
BENEFITS

Reliable and specific data to improve performance

  • Reliable, miniaturized and robust equipment adapted to be worn by an athlete
  • Data collection during long time series in order to analyse behavior on a sufficiently representative time allowing to study movement variability
  • Synchronized field data, interpretable and exploitable, acquisition in real conditions of practice
  • Opening of new fields of research improving the athlete technique and performance thanks to a full body analysis
