Interleukin-6 (IL-6) and IL-10 responses to seated control, moderate-intensity continuous and higher-intensity intermittent exercise protocols. Data presented are from plasma samples taken before, immediately after, 20 and 90 min post-protocol. All data are mean (95% confidence interval).
a
Higher at 0 min post-protocol compared with baseline (P < 0.05).
b
Higher during moderate-intensity visit compared with higher-intensity and control visits in lower fit group only (P < 0.05). P-values in bold represent a significant difference (P < 0.05).
