| Research Abstract |
Although exercise induces muscle damage, the underlying mechanisms are not fully understand. The present study examined the involvement of neutrophils and macrophages in the exhaustive exercise-induced acute muscle damage in mice by application of the inhibitory neutrophil migration model and macrophage depletion model. The administlation of anti-neutrophil antibody inhibited the infiltration of Ly-6G positive cells (neutrophils) in the gastrocnemius, and the administration of clodronate liposome reduced the infiltration of F4/80 positive cells (macrophages) and related inflammatory reactions. Therefore, it was demonstrated that neutrophils and macrophages are involved in the exercise-induced muscle damage.
