  • This experiment determined the acute and cumulative responses of IL-6 and TNF-7 to three consecutive days of intensive training (Session I, II and III). Results showed that exercise caused a similar increase in IL-6 from pre- to post-exercise for all sessions, but no changes in resting, baseline values. Results also showed an increase in TNF-7 after Sessions II and III, but not Session I. The percent change in TNF-7 was greatest for Session II, and resting TNF-7 was significantly elevated by the end of the study. In conclusion, three days of intensive training separated by ~24 hours do not result in a significant widening of the “Open Window” period following exercise, as the environment created by exercise in predominantly anti-inflammatory, as evidenced by increased IL-6. This means that athletes who train intensively for three consecutive days do not appear to be at a greater risk of becoming ill.
