Track and Field Performance Analysis
Accurately track the athlete's movement during all his trainings
The small GNSS-IMU sensor, weighting only 36 grams, is worn on the upper back during the entire training. Because of the small size and low weight the athlete is not aware of being tracked. At the end of the training, the data is uploaded from each sensor to our servers. There, our advanced algorithms and biomechanical models will automatically process the data and compute selected performance parameters. Everything is web-based and no special programs are needed.
Performance Analysis Options
For the moment we can analyze: sprint running, mid-distance running, hurdles, long jump. Triple jump, high jump, and pole vault are experimental and only the approach phase can be analyzed.
- Centre of mass speed
- Left / right step detection
- Speed changes inside a step
- Average step speed
- Vertical oscillations
- Cadence and step duration
- Step length
For easy interpretation of the performance data, for example for technique training, the synchronization unit allows to synchronize videos automatically with the data. Speed overlays on the video can thus be created automatically and help to browse through the data and understand better the performance of the athlete.
Each step is automatically detected and assigned to the left or right side. The curves are time-normalized to 100% step duration and speed and vertical displacement are averaged for the automatically detected maintenance phase. These plots allow to rapidly check if the athlete has asymmetries and whether his movement is executed efficiently.
Using motion constraints and the center of mass vertical acceleration, our system detects each foot strike. Combining that data with the center of mass kinematics obtained from our specialized fusion algorithm the system can then compute cycle duration, cycle speed, and cycle distance. Cycles parameters can be plotted against the running time or against covered distance.
Analyze the vertical displacement of the centre of mass. Our app provides the range of motion of this displacement for each step (black line with blue and orange dots) and the continuous displacement (gray) line. As with the cycle parameters, you can choose between a time or distance representation of the data.
