In recent years, nanotechnology (NT) has shown to be a multidisciplinary study area, increasing its range of applications in several spheres of human activity. Advancements in nanotechnology have been made in textile materials as a result of the quest for enhanced multifunctionality in engineering, industrial, technical, and medical textiles. Textile materials now have several uses thanks to the integration of cutting-edge technologies including photonic crystals, plasmonics, luminescence, architectural colorants, holography, LED displays, and metamaterials. The physicochemical behaviors of textiles, such as self-cleaning, UV protection, flame resistance, and antibacterial capabilities, have been enhanced by textile nanotechnology innovations such as nanoparticles (NPs) and sensor integration into textile materials. It is appropriate for use in health, medical, sporting, advanced engineering, pharmaceuticals, aerospace, military, automobile, food, and agricultural industries, among others since it offers flexible sensing capabilities, robotics, electrical conductivity, flexibility, and comfort. Metallic fibers that have been injected with nanoparticles, such as copper and silver NPs, have demonstrated antiviral and antibacterial activities. The purpose of this study is to give an overview of the uses of nanotechnology in several sports-related sectors, with a special emphasis on sports-related flooring, apparel, and footwear. Sport has been injected with several important factors. In-depth research is also done on garments made using nanotechnology. According to current trends, all types of sportswear will soon be impacted by the nanotechnology revolution.
