摘要

Graphene materials can emit far-infrared radiance, and existing studies have confirmed that graphene far-infrared radiation can promote microcirculation and promote locomotor ability. To study the effects of graphene content and knitted fabric structure on exercise-induced muscle fatigue, 12 kinds of specimens were prepared, including 4 kinds of far-infrared nylon yarns with graphene content and 3 kinds of tissue structures. Subjects wore different knitted pants and muscle fatigue was induced through jogging, with rectus femoris muscle activity monitored via surface electromyography. Results demonstrated that graphene far-infrared nylon fiber knitted pants significantly reduced exercise-induced muscle fatigue, and the type of face yarn was the main factor affecting the degree of muscle exercise fatigue, and the sweatpants with graphene added had a low degree of muscle fatigue at the rectus femoris muscle, and the tissue structure would also affect the degree of muscle fatigue, the 1 + 3simulated rib showed better anti-fatigue effect due to the thicker structure. Among them, the sample with 0.4% graphene content performed the best, and its rectus femoris fatigue threshold reached 214.10 s, which was 21.5% higher than that of the pure nylon control group.
