Figure 2. Changes in muscle soreness (DOMS) from the pre-exercise level following eccentric exercise of the knee extensor (KE), knee flexor (KF) and elbow flexor (EF) muscles. * p < 0.05 and ** p < 0.01 indicates significant difference compared with the baseline (pre-exercise). ‡‡ p < 0.01 and ‡‡‡ p < 0.001 indicates significant difference compared with EF. The symbols (●, ▪, Δ) and their error bars denote mean and SEM.
