Figure 4

Serum inflammatory cytokine levels tested using ELISA in week 0 (immediately following the training period) or after performing either a low repetition low force (LRLF), high repetition low force (HRLF), low repetition high force (LRHF) and high repetition high force (HRHF) task for 12 weeks. (A & E) Tumor necrosis factor alpha (TNF-alpha) in weeks 0 and 12. (B & F) Interleukin 1-beta (IL-1beta) in weeks 0 and 12. (C & D) IL-1alpha in weeks 0 and 12. Symbols: aa: p < 0.01, compared to LRLF rats; bb: p < 0.01, compared to HRLF rats; cc: p < 0.01, compared to LRHF rats; **: p < 0.01, compared to normal controls (NC) rats (mean values of NC rats are indicated by dashed line). Mean and SEM are shown.
