Increase in plasma concentrations of pro- and antiinflammatory
cytokines (e.g., interleukin-6,
interleukin-10, and interleukin-1 receptor antagonist).
Cytokines are low molecular-weight proteins and
peptides that help control and mediate interactions
among cells involved in immune responses.
Prolonged and intensive exercise bouts induce muscle
cell injury, causing a sequential release of pro- and
anti-inflammatory cytokines
