A team led by the Electronic and Biomedical Instrumentation (IEB) research group at the Universitat Polit\u00e8cnica de Catalunya – BarcelonaTech (UPC) is developing an electronic chip that enables more objective detection of potential infractions in race walking, which are currently judged solely by visual observation. The technology, already tested in official competitions, provides accurate, objective, and fair data on race walkers\u2019 loss of ground contact.<\/h4>

Race walking is a discipline based on walking, governed by specific rules that distinguish it from running. According to these rules, athletes must maintain continuous visual contact with the ground, and the leading leg must remain straight from first contact until it is vertically aligned under the body. However, it has been shown that human perception is not sufficiently accurate to detect certain losses of contact, which can lead to disputes and erroneous disqualifications by judges during competitions.

In this context, the Race Walking Electronic Control System (RWECS)<\/a> offers a technological solution that is both objective and precise for detecting infractions in race walking\u2014a sport where judges must currently determine whether athletes maintain constant ground contact using only visual cues, as required by current regulations. The system is based on electronic devices attached to shoelaces, weighing less than 15 grams and about the size of a one-euro coin, making them minimally intrusive for race walkers. This new device (dubbed the \u201cVAR for race walking\u201d) offers an objective, reliable, and fair solution, as it can record every step and detect losses of contact with the ground at a resolution of 0.002 seconds\u2014yielding a margin of error smaller than that of human observation.

As part of the project, a network infrastructure has been designed, configured, and deployed to track the devices using Bluetooth and WiFi technologies. Additionally, video processing tools have been developed to monitor compliance with the other key rule of the sport, which requires the front leg to remain straight from heel strike to the vertical position. This aspect is also currently judged subjectively, posing an additional challenge for implementing technological means to ensure objective enforcement.

Putting the \u2018VAR\u2019 to the test<\/h4>

The system has already been tested in an official competition of the Royal Spanish Athletics Federation (RFEA) in Tarragona and in an event held by the Catalan Athletics Federation in Barcelona. As a final project test, the system was validated during the Gran Premio Internacional Madrid Marcha Silb\u00f6 Telecom, a Gold category event of the World Race Walking Tour, which took place on Sunday, 1 June, on Madrid\u2019s Gran V\u00eda.

The development of RWECS marks the culmination of over a decade of research by the participating team, part of UPC\u2019s Department of Electronic Engineering. This latest trial was made possible thanks to students from the Bachelor\u2019s Degree in Telecommunication Technologies and Services Engineering (GRETST) at ETSETB, who tested the RWECS as part of the Advanced Engineering Project (PAE) subject.
