Abstract

Abstract Athletes continuously seek out creative methods and technologies to improve their physical fitness and overall performance. Wearable technology's progress offers a swift and eco‐conscious way to consistently observe physiological changes evidenced by biomarkers, stemming from an athlete's internal exertion or external workload. However, there is still a long distance to further understand the internal physiology of athletes which may bring hope to tailor training and recovery programs individually. The ongoing challenges faced by sports healthcare personnel are in finding biomarkers safely and continuously to control athletes' physical condition and tailor their recovery and eating patterns. The summary of this review encompasses the development of flexible and wearable electrochemical sensors. This article provides an overview of biofluids, commonly detected by wearable biochemical sensors and their mutual anatomical formations, with a focus on sweat and its associated biomarkers. Following this, its real‐world application in sports medicine becomes apparent, both theoretically and potentially. The paper ends by highlighting challenges and imagining the possible development of this exciting emerging field.
