Oxymotion Sp. z o.o., based in Lublin, Poland, develops and distributes the Q‑Lac sensor—a non-invasive wearable technology that monitors muscle oxygenation and lactic acid concentration in real time, without interrupting training sessions. This allows coaches and sports scientists to optimize training loads and performance continuously, rather than relying on invasive blood sampling. For example, one sports innovation program noted that the solution enables coaching staff to "prepare effective training tasks and manage the team line-up during a match."
