In sport, it is important to get the best out of an athlete, in order to guarantee the highest performance possible. Science has always given support to sport in order to reach this goal.
Nowadays, science is working on a new challenge: making athletes finish a marathon competition in less than 2 hours. Projections say that this goal will be accomplished in 2025. However, companies are putting their efforts into the development of technologies that could help making this happen earlier. In fact, in 2017, thanks to the project “Breaking 2 attempt” (Nike), this goal has almost been achieved: during a marathon in Monza, the winner completed the competition in only 2 hours and 25 seconds.
Different technical aspects and different parameters have to be analyzed in order to enhance an athlete’s performance. One of the most important aspects is the ground reaction force, that provides information about the interactions between foot and ground. Therefore, biomechanical models have to be created in order to optimize the push of the foot on the terrain and, from this point of view, the shoe can make a big difference in the athlete’s performance and therefore it has to be designed accurately.
Technology offers new solutions to monitor different parameters while the athlete is running. This is possible placing some wearables on the athlete’s foot. These devices are made up of inertial measurement units, sensors that are able to measure accelerations, angular velocities and magnetic fields in order to get information about the position and orientation of an object.
