Challenge:
In competitive swimming a fraction of a second can have great effect on the outcome. How can trainers gain more insight in the propulsive action of the grab start to increase performance of the athlete?
Solution:
Four national level swimmers were investigated. LifeMOD 3D models were created for each swimmer based on morphological parameters and kinematic data obtained by high speed video cameras.
The proposed approach allows predicting swimmer’s joint moments for each important articulation during the impulse phase of the grab start and to analyze the segmental coordination for each studied swimmer in order to optimize the performance. The model was successfully validated by comparing the predicted speed and power values with experimental ground reactions data collected in situ.

Value:
With validated models of the swimmers, this approach can be used for segmental coordination analysis of each phase of the grab start associated with the muscular activation investigation for each swimmer in order to optimize their performances.
