To meet the urgent demand for real-time

non-invasive and continuous monitoring in precision sports science

sweat wearable biosensors become a key research direction in competitive sports.Sweat wearable biosensing technology for competitive sports is systematically reviewed.Core detection techniques and performance verification status of key indicators such as electrolytes

lactic acid

glucose

pH value and cortisol are summarized.Their application value in typical scenarios such as hydration management in endurance sports

fatigue assessment in high-intensity interval training

and load monitoring in team sports is further discussed.Moreover

the enabling effect of artificial intelligence in interpreting complex sweat data is analyzed.Core technical challenges including sensor stability

data interpretation

and validation in actual competition environments are deeply investigated.Finally

future trends such as multimodal sensor integration

self-powered systems

and closed-loop interventions are discussed to provide forward-looking references for sports science and related industries.
