Physical exercise is prone to cause various abrasions and the wound has no certain rules, prone to inflammation, slow healing and easy to form scars. Sports skin trauma is a major problem that plagues sportsmen. How to use effective methods to promote sports injury wound healing, reduce wound surface and shorten the course of disease is a problem worthy of discussion and research. This article analyzes the characteristics of sports wounds, skin structure and their effects on wound healing, and discusses the effects of nano-material bacterial fibers on sports wound healing. This article mainly conducts experiments from the effects of nano-material bacterial fibers on skin tissue's foreign body metabolism, growth catalysis, skin surface capacitance and surface gas exchange. Tissue samples in different chemical environments are set up. Experimental results show that the adsorption capacity of nano-material bacterial fiber is 50% higher than that of carbon fiber and polyester fiber, which can remove harmful bacteria on the skin surface to prevent inflammation in a short time. In skin tissues, bacterial fibers combined with zinc ions at a concentration of 0.5wt% can achieve the highest catalytic effect and promote cell regeneration and wound healing at the wound. When the contact concentration of the wound and the bacterial fiber is 4.5wt%, the wound can get the highest rate of oxygen, which can achieve the best healing effect.
