Abstract

This study examines the effect of Far Infrared (FIR) active fabrics on muscle activity and blood oxygen saturation during exercise. FIR fabrics, containing nano-ceramic particles, emit infrared radiation that promotes blood circulation and thermal regulation. A comparative experimental approach was used with 30 male participants performing standardized workouts while wearing three types of sportswear: fully FIR-integrated, traditional polyester-spandex, and a hybrid design combining both materials. Results showed that the FIR-based garments led to the highest oxygen saturation and the lowest muscle activation, indicating improved efficiency and reduced fatigue. Traditional sportswear required greater muscular effort and resulted in lower oxygen levels, while the hybrid model delivered moderate results. The findings underscore the physiological advantages of FIR textiles in enhancing performance and comfort. This research offers practical implications for the design of smart sportswear and supports the integration of nanotechnology-based fabrics to meet the needs of athletes and individuals engaged in physical training.
