Resumo: | ABSTRACT Introduction Skeletal muscle injuries account for 10% to 50% of treadmill sports injuries. Insulin-like growth factor (IGF) is a family of polypeptides with both insulin-like anabolic and growth-promoting effects. Sports play a vital role in the recovery of skeletal muscle injuries. Objective The paper analyzes the ability of insulin-like growth factor 1 (IGF-1) to repair skeletal muscle injury caused by treadmill exercise. Method We injected drugs under the wound after exercise-induced injury in rats. The control group was injected with saline, and the experimental group was injected with an insulin-like growth factor. We conduct histological and electron microscopic structural analysis of rats, Results: After an injury, the experimental group formed a basal lamina protective film earlier than the control group, activated myoblasts, formed myofilaments, formed myotubes, and fused into muscle fibers earlier than the control group. The healing quality was also better. The experimental group was endogenous. The mRNA content of sex IGF-1 and IGF-2 both increased earlier than the control group. Conclusion Local injection of exogenous insulin-like growth factor-1 can stimulate the proliferation of myoblasts and accelerate the post-traumatic repair process of skeletal muscle caused by treadmill sports. Level of evidence II; Therapeutic studies - investigation of treatment results. |
